If someone asked you, “How long do you hope to live?”, what would you say? While many people will blurt out “100!”, I can only assume they envision themselves at that ripe old age without having major health problems. After all, who wants to live that long if your quality of life is sh*t?
That’s why it matters to take a health-first perspective when we talk about longevity.
You won’t be surprised to hear that nutrition is foundational whether you want to improve your health today, tomorrow, or 40 years from now. Is there a longevity diet? Sure, but you can design it yourself.
What you’re putting into your mouth is literally changing your gut microbiome — the community of microbes living and thriving in your digestive tract — and affecting every other part of your body.
If you’re not sure what I’m talking about, just search “gut-brain axis” or “how my gut microbiome affects my immune system”. Everything is connected and so much of it stems from our dietary choices. We can talk about that more later.
Anyway, I wanted to share some of the simple foods I prioritize in my diet to support my longevity.
Are they death-proof foods? Of course not, and I’m not Bryan Johnson.
But as a preventive health dietitian, I like to understand the evidence behind my food options and make the best choices for me. There’s plenty of data on how these foods can help me avoid conditions that could cut down my healthy living years.
Most importantly, these are everyday foods that don’t come with a crazy price (with the exception of inflation).
So, if you’re looking for an easy way to optimize your health today and down the road, here are 10 great longevity foods to look for at the grocery store.

1. Leafy Greens
Leafy greens like spinach, Swiss chard, romaine lettuce, and arugula are nutritional powerhouses that promote longevity.
Packed with vitamins A, C, and K, fiber, lutein, and antioxidants, they help combat oxidative stress and support bone and heart health. Eating greens is also associated with slowed cognitive decline.
I’ll admit, I used to really dislike greens and sometimes it’s still hard for me to get into a regular rhythm with them. But because I know how valuable they are as longevity foods, they stay on my grocery list.
How to Eat Them
- Add spinach to your smoothies, along with green apples, pears, pineapples, or ginger to help balance out the flavor
- Sautee Swiss chard with olive oil and garlic
- Chop romaine and arugula for a salad that can last all week in the fridge
- Toss greens into your breakfast tofu scramble or burrito
- Add them to your soup or pasta dishes
2. Berries
Berries, including blueberries, strawberries, blackberries, and raspberries, are among the best foods for longevity due to their high antioxidant content, which fights inflammation and protects against chronic diseases. They’re also a great source of fiber, promoting gut and cardiovascular health.
How to Eat Them
- Sprinkle berries on oatmeal
- Use frozen berries for smoothies
- Make a mixed berry compote for your waffles or pancakes
- Add them to muffin batters
- Try dehydrated or freeze-dried berries
- Enjoy them on their own!
3. Nuts and Seeds
Nuts and seeds, such as walnuts, almonds, cashews, Brazil nuts, sunflower seeds, chia seeds, hemp seeds, and flaxseeds, are rich in heart-healthy fats, plant-based protein, and essential nutrients like magnesium and omega-3s.
Eating nuts and seeds is associated with a lower risk of heart disease and improved brain health.
I try to eat 4 Brazil nuts per month to help ensure I meet my selenium needs without overdoing it. Just one Brazil nut provides over 100% of your daily needs!
How to Eat Them
- Add them to yogurt
- Mix them into salads
- Top your oatmeal with them
- Use raw cashews to make “cashew cream” for thickening up your soups (equal parts cashews and water, blended until smooth)
- Make a homemade trail mix with nuts, seeds, dried fruit, pretzels, and dark chocolate
- Add chia, flax, and hemp seeds to your smoothies
- Mix them into pancake and muffin batter
- Use chia or ground flax seeds to make vegan “eggs” to use for baking (1 “egg” = 1 Tbsp seeds + 2.5 Tbsp water, mixed and let sit until it forms a gel)
4. Legumes
Legumes are admittedly a food group I wasn’t super comfortable with until I went plant-based. Now, they’re a regular on my menu.
Legumes include beans, peas, lentils, and peanuts. They’re a longevity staple, providing a rich source of fiber, protein, and essential minerals like iron and folate. They support heart health, regulate blood sugar, and improve gut function.
How to Eat Them
- Toss chickpeas into salad, make chickpea noodle soup, or use them to make “chickpea salad” sandwiches in place of shredded chicken
- Blend beans into a paste to slather on tortillas and make enchiladas or quesadillas
- Throw beans, peas, and lentils into your soups, salads, and stews
- Mix peas into your spaghetti or mac and cheese
- Use tofu for stir-fries, pasta dishes, and breakfast scrambles
- Add edamame to your salads or make edamame hummus
5. Whole Grains
Whole grains like quinoa, brown rice, and oats are excellent for promoting longevity due to their high fiber content and nutrient density. They help lower high cholesterol, stabilize blood sugar levels, and reduce inflammation.
How to Eat Them
- Choose brown rice over white rice
- Make oatmeal for breakfast, like the kind that comes in bulk, not the sugary packets
- Choose 100% whole wheat bread and pasta over white versions
- Make grain-based bowls using quinoa, barley, or amaranth
6. Fermented Foods
Probiotics are friendly bacteria that help support your digestive system, immune function, and overall health. While you can get probiotics from supplements, you can also find them in fermented foods such as kimchi, sauerkraut, miso, and kefir.
How to Eat Them
- Use tempeh (fermented soybeans) in stir-fries or crumbled up for chili or Sloppy Joes
- Add some sauerkraut or kimchi to your grain bowls, wraps, or sandwiches
- Make miso soup full of vegetables and tofu
7. Cruciferous Vegetables
Cruciferous vegetables like broccoli, cauliflower, Brussels sprouts, and cabbage are packed with compounds that promote longevity, including sulforaphane, which has been shown to reduce inflammation and protect against certain cancers.
They are also high in fiber, supporting digestive health and weight management.
How to Eat Them
- Roast cruciferous vegetables in the oven drizzled with a bit of olive oil, salt and pepper
- Chop broccoli and cauliflower florets to add to soups
- Slice Brussels sprouts and red cabbage for your salads and slaws
- Eat them raw with hummus or dip
- Massage chopped kale with olive oil and lemon juice until soft for a nutrient-rich salad base
8. Mushrooms
Mushrooms, such as shiitake, maitake, white button, and cremini, are unique longevity foods, packed with compounds like beta-glucans that support immune health, brain health, and reduce inflammation. They’re also rich in antioxidants and B vitamins.
Personally, I don’t love mushrooms, but I can tolerate them chopped small and sauteed into various dishes.
How to Eat Them
- Sauté mushrooms as a side dish
- Add them to soups
- Chop them and use them as a meat substitute, like in homemade meatballs
- Slice them and add to breakfast scrambles
9. Green Tea
Green tea is revered for its longevity-promoting properties, thanks to antioxidants like EGCG that protect against cellular damage, support heart health, and enhance brain function. Sipping green tea can also improve metabolism and reduce stress levels.
How to Drink It
- Enjoy a warm cup of green tea in the morning
- Make iced green tea to keep in the refrigerator
10. Dark Chocolate
Dark chocolate, ideally with at least 70% cocoa, is not only a treat but also a longevity ally. Rich in flavonoids, it supports heart health, reduces blood pressure, and enhances mood. Its antioxidant properties make it a great choice for fighting inflammation.
How to Eat It
- Find a delicious dark chocolate bar to enjoy as a dessert
- Shave it to add to your oatmeal or yogurt
- Add dark chocolate chunks to pancake or muffin batters
