15 Healthiest Foods I Eat Every Week as a Doctor

There are 15 foods that I eat pretty much every week that have probably done more for my long-term health than anything else I've tried. Most of what determines how long we live and how well

we age comes down to what we consistently put into our bodies. And

that largely means food. After nearly 10 years working in emergency medicine, I've seen the end result of decades of poor dietary choices play out in real time. People arrive with heart attacks,

time. People arrive with heart attacks, with strokes, type 2 diabetes, and a whole cascade of preventable conditions that all share a common thread. Years of

eating the wrong things. The interesting

part is that most people think longevity is about finding the right supplement stack or discovering some exotic superfood when in reality it comes down

to boring, repeatable, single ingredient foods that you'd recognize instantly if you walked past them in a supermarket.

Ultrarocessed foods have made nutrition feel impossibly complicated when it genuinely shouldn't be. I'm Dr. Alex and during my time working as a doctor in the UK, I've become quite obsessed with

the patterns and the data behind living longer and living in genuine good health. What I want to do is share the

health. What I want to do is share the insights I've gathered over those years and hopefully teach you something that in this day and age our doctors simply don't have time to explain. And if you

stay until the end, I'll also mention one of the worst everyday foods that quietly makes up a huge proportion of most people's diets without them ever realizing it. Starting at number 15.

realizing it. Starting at number 15.

Now, before we go on to the good stuff like dark chocolate or eggs, I have to mention water. I know that sounds almost

mention water. I know that sounds almost too obvious, but most people really are walking around in this chronic state of mild dehydration without knowing about

it. Your thirst mechanism isn't actually

it. Your thirst mechanism isn't actually that reliable, especially as you get older. By the time you feel thirsty,

older. By the time you feel thirsty, you're already dehydrated, and that lag gets worse with age. Working in A&E, one of the most routine blood tests that we

do is to measure your kidney function.

It's called GFR or glomeular filtration rate. It's genuinely surprising how many

rate. It's genuinely surprising how many people over the age of 40 have a GFR lower than it should be for their age, meaning their kidneys aren't filtering blood as efficiently as they should do.

While some decline in your kidney function is normal aging, a significant portion is preventable. Chronic

dehydration forces your kidneys to work harder to concentrate urine and maintain electrolyte balance. Over time, that

electrolyte balance. Over time, that extra strain leads to gradual kidney decline. And once that function is lost,

decline. And once that function is lost, you don't get it back. Dehydration

affects pretty much every system in your body. Your blood becomes more viscous,

body. Your blood becomes more viscous, making your heart work harder. Your

brain function declines. Even mild

dehydration impairs your concentration, your memory, and your mood. Your joints

and your muscles don't function as well.

Your digestive system slows down, leading to constipation. often. Most

people don't connect these symptoms to hydration because they've been mildly dehydrated for so long that it just feels normal. So, what I do is

feels normal. So, what I do is incredibly simple. Whenever I go into

incredibly simple. Whenever I go into the kitchen at home, I drink a glass of water. It doesn't matter if I'm thirsty

water. It doesn't matter if I'm thirsty or not. It's just a habit tied to being

or not. It's just a habit tied to being in that space. At work, I take a couple of bottles and make sure to finish them before my shift ends. The goal isn't to

force down liters and liters of water because that really is dangerous. The

goal is just to be consistent throughout the day and drink gradually as you go.

The longevity link here is about kidney preservation and cellular function. Your

kidneys fill to waste. They regulate

electrolytes and they maintain your blood pressure. When they're not

blood pressure. When they're not functioning properly, you get a cascade of metabolic problems that accelerates aging and increases your risk of cardiovascular disease. Staying hydrated

cardiovascular disease. Staying hydrated is one of those really boring, unglamorous habits that doesn't feel like it's doing much in the moment, but over decades is one of the most protective things that you can do for

your long-term health. That's why water makes the list, even though it's not technically a food. Moving on to number 14, and we have dark chocolate. And I'm

talking about proper dark chocolate with at least 70% cocoa content. Now, I know what you're thinking. Chocolate on a list of the healthiest foods sounds

suspicious, but there's a reason I eat a small amount of high quality dark chocolate almost every day, and it has nothing to do with taste alone. The

thing is, most people don't realize that cocoa is actually one of the richest sources of polyphenols you can find in food. And these compounds have a

food. And these compounds have a measurable effect on vascular health.

What happens when you eat dark chocolate with a very high cocoa content is that those flavonoids, a specific type of polyphenol, get absorbed and eventually trigger the production of nitric oxide

in the lining of your blood vessels.

Nitric oxide is essentially a signaling molecule that tells your blood vessels to relax and expand, which improves blood flow and reduces your blood pressure. That might sound trivial, but

pressure. That might sound trivial, but vascular flexibility is one of the key markers of cardiovascular health as we age. Stiff, inflexible arteries are what

age. Stiff, inflexible arteries are what leads to hypertension, to heart attacks, and strokes decades down the line.

Obviously, that doesn't mean you should eat an entire bar every day because dark chocolate is still calorie dense. What I

do is keep it around 10 to 20 grams, which is enough just to get the benefits without meaningfully affecting my overall calorie intake. The longevity

link here is fairly straightforward.

Vascular health is directly tied to reduced heart attack and stroke risk, which are the two leading causes of death globally. That's why dark

death globally. That's why dark chocolate makes the list. Moving on to number 13, and we have eggs. And I eat these almost every single day in some

form. Whether it's boiled, scrambled in

form. Whether it's boiled, scrambled in olive oil, poached, or even dippy eggs.

Eggs have had a really complicated reputation over the years, largely because of outdated concerns about dietary cholesterol. But the science has

dietary cholesterol. But the science has moved on significantly since then. What

we now understand is that for most people, the cholesterol that you eat in food has very little impact on the cholesterol levels in your blood. The

liver produces the majority of your cholesterol anyway, and it regulates that production based on how much you're consuming. The real driver of unhealthy

consuming. The real driver of unhealthy blood cholesterol is not dietary cholesterol. It's excessive saturated

cholesterol. It's excessive saturated fats, trans fats, and chronic inflammation, which comes from lots of different things. The reason eggs are so

different things. The reason eggs are so valuable is that they're a complete protein, meaning they contain all nine essential amino acids that your body can't produce on its own. That makes

them incredibly efficient for muscle maintenance and repair, which becomes more important as you age. As well as that, eggs are one of the best sources of choline, a nutrient that's critical

for brain health and neurotransmitter function. Most people don't get enough

function. Most people don't get enough choline, and cognitive decline is one of those things that you really want to prevent early rather than try to reserve later. From a metabolic perspective,

later. From a metabolic perspective, eggs are also exceptionally good at keeping you full. Protein has a high satiety effect, which means it stabilizes your blood sugar and reduces

the likelihood of you reaching for snacks an hour later. That stability is what protects you from the glucose spikes and the crashes that over time

contribute to insulin resistance and type 2 diabetes. The longevity angle here is about muscle preservation and metabolic stability. Two things that

metabolic stability. Two things that determine how well you function in your 70s, 80s, and beyond. Number 12 is cottage cheese. And I usually have this

cottage cheese. And I usually have this on seeded sourdough toast, sometimes with a bit of smoked salmon or some seeds on top. Cottage cheese is one of those foods that doesn't get nearly

enough attention, but it's genuinely one of the most useful things that you can keep in your fridge. The main reason is the protein density. Cottage cheese is

around 80% protein by calorie, which is rare for something that's also relatively low in fat and easy to eat in decent quantities. What happens when you

decent quantities. What happens when you eat protein alongside carbs is that it slows down the rate at which glucose gets absorbed into your bloodstream.

That means that if you are having toast, adding cottage cheese dramatically reduces the glycemic impact of that meal compared to eating toast on its own.

Lower glucose spikes mean lower insulin spikes and lower insulin spikes over time mean better insulin sensitivity and a lower risk of metabolic disease. As

well as that, cottage cheese is a fermented dairy product, which means it contains beneficial bacteria that supports your gut health. The

fermentation process also makes it easier to digest for people who struggle with regular dairy. Now, from a longevity perspective, cottage cheese hits multiple targets at once. High

protein intake is associated with better muscle mass as you age, which is one of the strongest predictors of functional independence and quality of life in older adults. The calcium content

older adults. The calcium content supports bone health, which helps to prevent fractures and the downstream complications that often follow a fall in later life. That combination of

muscle preservation, of bone health, and metabolic stability is exactly what you want to optimize if your goal is to age well and stay capable as long as possible. Coming in at number 11, and we

possible. Coming in at number 11, and we have peacans and walnuts, which I usually eat just out of a packet that are lightly roasted and salted. Now, I

know the immediate concern here is calories. Nuts are really calorie dense,

calories. Nuts are really calorie dense, and if you're not paying attention, it's really easy to overdo it. But the thing is, nuts have an extremely high satiety

effect, meaning they keep you full for hours despite the calorie content.

That's because of the combination of fat, of fiber, and protein in these nuts, which slows your digestion down and helps prevent blood sugar crashes that make you reach for more food.

Walnuts in particular are one of the richest plant sources of omega-3 fatty acids, specifically alpha linoleic acid, which gets partially converted into the

longer chain omega-3s that your brain and heart need. There's solid evidence that regular nut consumption improves lipid profiles. It raises HDL

lipid profiles. It raises HDL cholesterol. It lowers LDL cholesterol

cholesterol. It lowers LDL cholesterol and reduces triglycerides. That's a

meaningful shift in cardiovascular risk.

and it happens from eating a handful of nuts most days. What's really compelling about nuts is the consistency of the data around longevity. Large perspective

studies have repeatedly shown that people who eat nuts regularly have a lower risk of all cause mortality compared to people who don't. Now,

that's not just cardiovascular death.

That's death from all causes, which suggests that nuts are doing something beneficial across multiple systems in the body. The fiber content supports

the body. The fiber content supports your gut health. The fats reduce inflammation. And the micronutrients,

inflammation. And the micronutrients, the magnesium, the vitamin E, the selenium, they fill gaps that most people's diets are missing. That's why

nuts make the list even though they're calorie dense. The benefits massively

calorie dense. The benefits massively outweigh the concerns as long as you're eating them in reasonable amounts. At

number 10, we have pumpkin and sunflower seeds. And I sprinkle these on almost

seeds. And I sprinkle these on almost every meal that I eat, from salads to toast to soups, most breakfasts, or just eaten on their own as a snack. Seeds are

one of those foods that people completely overlook, but they are genuinely one of the most nutrient-dense things that you can add to your diet, and they go on anything. Pumpkin seeds

are loaded with magnesium, which is a mineral that the majority of people don't get enough of. Magnesium is

involved in over 300 enzyatic reactions in the body, including energy production, muscle function, and blood pressure regulation.

Sunflower seeds are high in vitamin E, in selenium, and healthy fats. And both

types of seeds contain a decent amount of fiber. Now, that fiber is what feeds

of fiber. Now, that fiber is what feeds the beneficial bacteria in your gut. And

those bacteria produce short chain fatty acids that reduce inflammation and improve insulin sensitivity. There's

also evidence that a diverse gut microbiome is associated with better metabolic health, better immune function, and even better mental health through the gut brain axis. From a

longevity perspective, seeds are really, really valuable because they fill micronutrient gaps that are difficult to address otherwise. Just like the nuts we

address otherwise. Just like the nuts we just talked about, most people eating a western diet are deficient in magnesium, in zinc, and selenium. And those

deficiencies have downstream effects on everything from bone health to immune function to DNA repair. Seeds are just so incredibly easy to incorporate into your diet. You don't need to cook them.

your diet. You don't need to cook them.

You don't need to prepare them. You just

add them to whatever you're already eating. And that's the kind of

eating. And that's the kind of loweffort, high impact habit that actually sticks over time. Moving on to number nine, and we have beetroot or

beets if you're across the pond. And I

eat these roasted, raw in salads, or just as a simple side dish with a bit of olive oil and salt on top. Beetroot is

one of those vegetables that people either love or hate. But from a physiological perspective, it's doing some genuinely remarkable things in your body. The key compound here is dietary

body. The key compound here is dietary nitrate, which gets converted into nitric oxide through a multi-step process involving bacteria in your mouth

and your stomach. Nitric oxide is the same molecule I mentioned earlier with dark chocolate and then also later on with kale. It's what keeps your blood

with kale. It's what keeps your blood vessels flexible and responsive. The

difference with beetroot is that the nitrate content is extraordinarily high, which means that you get a significant boost in nitric oxide production from eating it regularly. That translates

into lower blood pressure, better blood flow, and improved exercise performance.

There's actually data from control trials showing that beetroot juice can lower systolic blood pressure by several points, which might not sound dramatic, but at a population level, that

reduction would prevent thousands and thousands of heart attacks and strokes.

What's really interesting about beetroot is that the benefits seem to extend beyond just cardiovascular health.

There's evidence that the nitrates improve mitochondrial efficiency, which is how your cells produce energy. Better

mitochondrial function means better physical performance, better recovery, and potentially slower aging at the cellular level. Beetroo also contains

cellular level. Beetroo also contains beta lanes, which are these pigments that have antioxidant and anti-inflammatory properties. Those

anti-inflammatory properties. Those compounds help reduce oxidative stress, which is one of the underlying mechanisms of aging. The longevity link with beetroot is really about

cardiovascular protection and metabolic efficiency. Keeping your blood vessels

efficiency. Keeping your blood vessels healthy and your mitochondria functioning well are two of the most important things that you can do to reduce your disease risk as you age. The

fact that beetroo is low in calories, high in fiber, and easy to prepare makes it one of those foods that's worth eating regularly, even if you're not convinced by the taste at first. At

number eight, we have kafir, which is a fermented dairy drink that I usually have in the morning, sometimes mixed with berries or seeds. Kafir is similar to yogurt in some ways, but the

fermentation process is different, and that difference matters quite a bit from a health perspective. Kafir is made using kafir grains, which are a

combination of bacteria and yeast that ferment the milk and produce a much more diverse range of probiotic strains than you'd get from regular yogurt. What

happens when you consume kafir regularly is that you're introducing these beneficial bacteria into your gut and those bacteria help maintain the balance of your gut microbiome.

A healthy microbiome is linked to better immune function, better metabolic health, reduced inflammation, and even better mental health again through the gut brain axis. The fermentation process

also breaks down lactose, which means that many people who struggle with dairy can tolerate kafir without issues. As

well as that, kafir is high in protein, in calcium, and B vitamins, all of which support your muscle maintenance, your bone health, and your energy metabolism in general. There's growing evidence

in general. There's growing evidence that fermented foods are associated with better health outcomes. A study from Stanford showed that people who increase their intake of fermented foods

experience reduced markers of inflammation and increased microbiome diversity, both of which are protective against chronic disease. Kafir

specifically has been studied for its effects on blood pressure, on cholesterol levels, and blood sugar control. And the results are

control. And the results are consistently positive. The mechanism

consistently positive. The mechanism seems to be partly due to the probiotics themselves and partly related to the bioactive peptides that are produced during fermentation.

The longevity angle is about maintaining a healthy gut microbiome which becomes increasingly important as you age.

Microbiome diversity tends to decline with age and that decline is associated with frailty with immune dysfunction and increased inflammation.

Eating fermented foods like kafir is one of the most effective ways to preserve that diversity and support your long-term metabolic and immune health.

The fact that it's also high in protein and easy to incorporate into your daily routine makes it one of those foods that's well worth prioritizing. Now,

kale has become a bit of a cliche in health circles, but there's a reason it keeps coming up. It's genuinely one of the most nutrient-dense leafy greens that you can eat. What makes kale

particularly valuable is the combination of polyphenols, vitamin K, and nitrates.

Polyphenols are the plant compounds that have antioxidant and anti-inflammatory effects, and they've been consistently linked to lower rates of chronic disease. Vitamin K is essential for bone

disease. Vitamin K is essential for bone health and proper blood clotting, and most people don't get nearly enough of it. The nitrates in kale are what really

it. The nitrates in kale are what really sets it apart from other veg. Nitrates

get converted into nitric oxide in the body. And as I mentioned earlier with

body. And as I mentioned earlier with beetroot and dark chocolate, nitric oxide is what keeps your blood vessels flexible and responsive. That vascular

flexibility is one of the key determinants of cardiovascular health as you age. Stiff arteries lead to high

you age. Stiff arteries lead to high blood pressure which leads to heart attacks and strokes. So anything that improves vascular function is worth paying attention to. The longevity link

with kale is about chronic inflammation and oxidative stress, both of which accelerate aging at a cellular level.

There's data showing that people who eat more leafy greens, like spinach and kale, have slower rates of cognitive decline, better cardiovascular outcomes, and lower all cause mortality. The

practical note here is that it doesn't have to be fancy. All I do is put a bag of sliced kale into a bacon tray, drizzle it with olive oil, put some salt on, and put it in the oven for 10

minutes. The goal is consistency, so

minutes. The goal is consistency, so just try eating it every week if you can. Coming in at number six, and we

can. Coming in at number six, and we have salmon. And I would say I eat this

have salmon. And I would say I eat this probably twice a week. Either smoked

salmon with some scrambled eggs for breakfast or as fillets for dinner.

Salmon is one of the best sources of omega-3 fatty acids that you can get, specifically EPA and DHA, which are the longchain omega-3s that your body can

actually use directly without needing to convert them first. Those omega-3s have a measurable anti-inflammatory effect.

And chronic inflammation is one of the underlying drivers of almost every age related disease. Cardiovascular disease,

related disease. Cardiovascular disease, dementia, cancer, you name it. What

happens when you eat omega-3 rich fish like salmon is that those fatty acids get incorporated into the membranes of your cells, including the cells in your

brain and your heart. Now, that changes how those cells function, reducing inflammation, improving insulin sensitivity, and protecting against arhythmias. There's strong evidence from

arhythmias. There's strong evidence from randomized control trials that omega-3 supplementation reduces the risk of cardiovascular events. And eating whole

cardiovascular events. And eating whole fish gets you all of that plus high quality protein, vitamin D, and selenium. The brain protection angle is

selenium. The brain protection angle is really important for longevity. DHA

makes up a significant portion of the fat in your brain. And higher omega-3 intake is associated with better cognitive function and slower rates of cognitive decline. That's not just about

cognitive decline. That's not just about memory. It's about maintaining executive

memory. It's about maintaining executive function, processing speeds, and the ability to live independently as you age.

The reason salmon makes the list is because it's one of the most efficient ways to get those omega-3s without needing to rely on supplements, and it's something that you can eat regularly without getting bored. At number five,

we have blueberries. And I almost always eat these with yogurt and seeds to reduce the glucose spike and to add protein to the meal. Blueberries are one of the most studied fruits when it comes

to health and longevity. And the reason for that is the extraordinarily high concentration of polyphenols, particularly anthocyanins, which are what gives blueberries that deep blue

color. Those anthocyanins have powerful

color. Those anthocyanins have powerful antioxidant and anti-inflammatory effects, and they've been shown to cross the bloodb brain barrier, which means they can directly affect brain function.

The thing about eating blueberries on their own is that they do contain natural sugars. And while eating fruit

natural sugars. And while eating fruit sugar is different from added sugar, it can still cause a glucose spike if you're eating a large amount without anything else. That's why I pair

anything else. That's why I pair blueberries with yogurt and seeds. The

protein and fat slow down the absorption of glucose, which keeps your blood sugar stable and prevents the insulin spike that would otherwise occur. That

combination also keeps you full for longer, which is important if you're trying to maintain a healthy weight.

There's compelling data showing that people who eat berries regularly have better cognitive outcomes as they age.

One study followed older adults over several years and found that those who ate more blueberries and strawberries had slower rates of cognitive decline compared to those who didn't. And the

mechanism seems to be related to reduced oxidative stress and inflammation in the brain. Both of which contribute to

brain. Both of which contribute to diseases like Alzheimer's.

As well as that, there's evidence that blueberries improve vascular function and may reduce blood pressure, which adds another layer of cardiovascular protection. The longevity link with

protection. The longevity link with blueberries is really about brain health and metabolic protection. The polyphenol

supports cognitive function, and fiber supports your gut health, and the low calorie density means that you can eat them regularly without affecting your weight. The key is eating them as part

weight. The key is eating them as part of a balanced meal or a snack rather than isolation, which is why pairing them with yogurt and seeds is such an effective strategy. And number four, we

effective strategy. And number four, we have black coffee. Though I need to make this really clear that it's not good to drink this immediately when you wake up.

The reason for that is cortisol, which naturally peaks in the first hour or so after you wake up. Drinking coffee

during that peak can blunt your body's natural cortisol response over time, which means that you end up relying on caffeine more heavily just to feel normal. What I do is drink water first

normal. What I do is drink water first and then have a coffee about an hour after waking up, which respects that natural cortisol rhythm and makes the caffeine more effective. The health

benefits of coffee have been studied extensively and the data is remarkably consistent. Moderate coffee consumption

consistent. Moderate coffee consumption is associated with lower all cause mortality. Again, that's not just

mortality. Again, that's not just cardiovascular death. It's death from

cardiovascular death. It's death from all causes, which suggests that coffee is doing something protective across multiple organ systems. The polyphenols in coffee have antioxidant and

anti-inflammatory effects. And there's

anti-inflammatory effects. And there's specific evidence that coffee consumption is linked to better liver health and a lower risk of liver disease. What's interesting about coffee

disease. What's interesting about coffee is that the benefits seem to come primarily from polyphenols, not the caffeine. Decaf coffee still shows

caffeine. Decaf coffee still shows protective effects in studies, which means it's not just the stimulant effect that's valuable. Having said that,

that's valuable. Having said that, caffeine itself does have some benefits.

It improves your cognitive function. It

enhances physical performance and it may reduce the risk of neurodeenerative diseases like Parkinson's and Alzheimer's. Drinking two to three cups

Alzheimer's. Drinking two to three cups of coffee a day, either black coffee or just with a bit of milk, seems to be the sweet spot where you get the benefits without the downsides of excessive

caffeine intake like destructed sleep or increased anxiety. Number three on our

increased anxiety. Number three on our list is mushrooms. And I usually fry these lightly in olive oil and eat them on toast or as a side to meals.

Mushrooms are one of those foods that don't get nearly enough credit for how nutritionally dense they are. They're

incredibly low in calories, but high in fiber, in B vitamins, and minerals like selenium and potassium. What makes

mushrooms really interesting from a health perspective is the presence of betaglucans, which are the polysaccharides that have immune modulating effects. Betagal glucans

modulating effects. Betagal glucans essentially train your immune system to respond more effectively to threats without becoming overactive which is important because an overactive immune

system leads to chronic inflammation and autoimmune conditions. There's also

autoimmune conditions. There's also evidence that certain types of mushrooms like shiakei or oyster have specific compounds that support immune function and may even have anti-cancer

properties. So obviously that research

properties. So obviously that research is still in the relatively early stages.

From a longevity perspective, mushrooms are really valuable because they're nutrient-dense without adding many calories, which is exactly what you want if your goal is to age well without gaining weight. They're also one of the

gaining weight. They're also one of the few non-animal sources of vitamin D, especially if they've been exposed to sunlight or UV light during growing.

Vitamin D deficiency is extremely common and linked to everything from bone health to immune function and mood regulation. The fact that you can get a

regulation. The fact that you can get a decent amount of vitamin D from mushrooms makes them really useful, especially if you're not eating much fatty fish or spending much time in the

sun. And number two, we have sauerkraut,

sun. And number two, we have sauerkraut, which is a fermented cabbage that I usually eat as a side with main meals or sometimes just on its own. Sauerkraut is

another one of those fermented foods that's doing multiple things at once for your health. The fermentation process

your health. The fermentation process increases the bioavailability of nutrients in the cabbage, which means that your body can absorb more of the vitamins and minerals that are present.

As well as that, sauerkraut is packed with probiotics, beneficial bacteria that support your gut health and immune function. What's particularly valuable

function. What's particularly valuable about sauerkraut is that it's one of the most affordable and accessible fermented foods that you can eat. You don't need to buy expensive probiotic supplements

when you can get live bacteria from real food. The probiotics in sauerkraut help

food. The probiotics in sauerkraut help maintain the diversity of your gut microbiome, which is linked to better metabolic health, reduced inflammation, and improved immune function. There's

also evidence that fermented vegetables specifically can reduce the risk of certain cancers, particularly digestive cancers, though the mechanisms are still being studied. The other benefit of

being studied. The other benefit of sauerkraut is that it has a high fiber content. Cabbage is naturally high in

content. Cabbage is naturally high in fiber and that fiber feeds the beneficial bacteria in your gut, creating short- chain fatty acids that have anti-inflammatory effects. Those

short- chain fatty acids also improve your insulin sensitivity and support your metabolic health, which is critical for preventing type 2 diabetes and maintaining a healthy weight as you age.

The vitamin C content in sauerkraut is also surprisingly high, especially if it's eaten raw or minimally cooked. And

vitamin C is essential for immune function, collagen production, and antioxidant protection. The longevity

antioxidant protection. The longevity link with sauerkraut is really about gut health, and inflammation. A healthy,

diverse microbiome is one of the strongest predictors of healthy aging.

And fermented foods, like we've touched on earlier, are one of the most effective ways to support that diversity. The fact that sauerkraut is

diversity. The fact that sauerkraut is low in calories, it's easy to store and can be eaten regularly without much preparation makes it one of those foods that fits seamlessly into a long-term

healthy eating pattern. And finally, at number one, we have extra virgin olive oil. And I use this every single day

oil. And I use this every single day really generously on pretty much everything from salads to toast instead of butter, any sort of veg, and pretty

much any cooking that I do. Olive oil is one of the most wellstudied foods in the context of longevity, largely because it's a central component of the Mediterranean diet, which is

consistently associated with lower rates of cardiovascular disease, of dementia, and all cause mortality. What makes

extravirgin olive oil particularly valuable is the polyphenol content which is what gives it that slightly bitter peppery taste. Those polyphenols have

peppery taste. Those polyphenols have powerful anti-inflammatory and antioxidant effects and they specifically protect the endothelium which is the lining of your blood

vessels. Endothelial dysfunction is one

vessels. Endothelial dysfunction is one of the earliest signs of cardiovascular disease and it happens years before you develop high blood pressure or have a heart attack. Olive oil helps preserve

heart attack. Olive oil helps preserve that endothelial function which keeps your blood vessels flexible and responsive. There's also evidence that

responsive. There's also evidence that olive oil improves your lipid profiles.

It raises your HDL cholesterol and it reduces oxidative stress. The longevity

around olive oil is some of the strongest that we have for any single food. Large prospective studies show

food. Large prospective studies show that people who consume more olive oil have a lower risk of cardiovascular events, neurodeenerative diseases, and overall mortality. Now, that's not just

overall mortality. Now, that's not just correlation. There are plausible

correlation. There are plausible mechanisms that explain why olive oil is protective. And those mechanisms have

protective. And those mechanisms have been validated in control trials. The

key is making sure that you're using extra virgin olive oil because that's the type that retains the polyphenols.

Refined olive oil loses most of those beneficial compounds during processing.

So, it's not going to give you the same benefits. Now, as I promised earlier, I

benefits. Now, as I promised earlier, I want to mention one of the worst everyday foods that quietly makes up a huge proportion of most people's diets without them ever realizing it. And that

food is soft sliced white bread. The

everyday white bread that we see. And

the reason this is such a problem isn't because one slice is going to kill you.

It's obviously not. The problem is that white bread is ultrarocessed. It's low

in fiber and has an extremely high glycemic load. When you eat it, your

glycemic load. When you eat it, your blood sugar spikes rapidly. Your insulin

spikes in response and then an hour or two later, your blood sugar crashes and you're hungry again. What makes this particularly insidious is that most people eat white bread around twice a

day. toast for breakfast, a sandwich for

day. toast for breakfast, a sandwich for lunch, and that means it's making up a disproportionate amount of the daily calorie intake. Over time, that pattern

calorie intake. Over time, that pattern leads to insulin resistance. It leads to weight gain and eventually type 2 diabetes. The other issue is that white

diabetes. The other issue is that white bread crowds out real food. If you're

filling up on white bread, then you're probably not eating eggs, veg, nuts, or seeds, or any of the other nutrient-dense foods that actually support your long-term health. The thing

is, bread itself isn't the enemy. A

seeded sourdough that I eat most days, for example, can absolutely be part of a healthy diet when eaten with protein and fat. But soft white bread is basically

fat. But soft white bread is basically empty calories with a massive metabolic cost. It's one of those foods where the

cost. It's one of those foods where the cumulative effect over years and decades is what matters. It doesn't feel harmful in the moment, but it quietly replaces real food every single day, and that's

where the damage happens. So to bring this all together, longevity isn't about eating perfectly all the time or finding some magic superfood that fixes

everything. It's about repeatable,

everything. It's about repeatable, somewhat boring, single ingredient foods that you can eat consistently over years and decades. Most people don't need

and decades. Most people don't need supplements. They need fewer packets,

supplements. They need fewer packets, fewer processed foods, and more real food that looks like it came from a plant or an animal. The 15 foods I've

talked about today aren't exotic.

They're not expensive, and they're not difficult to find. They are just consistently good choices that over time compound into better metabolic health, better cardiovascular health, and a

longer, more capable life. And if you found this video useful and you learned something today, then please subscribe to the channel because it genuinely helps this channel reach more people who
