The secret to longevity may seem elusive—but a life-lengthening diet doesn’t have to be overly complicated! In fact, according to longevity-focused nutrition experts, many of the foods that best support long-term health are simple and accessible. When you prioritize nutrients, anti-inflammatory benefits, and high-quality proteins, you can do wonders to boost your metabolism, strengthen your muscles, and protect cognitive function as you age.
ButcherBox lead nutritionist and registered dietitian Amy Shapiro says longevity-supportive eating is refreshingly straightforward when you focus on foods that nourish your system at the cellular level. “As a dietitian, I find that the foods that truly support longevity aren’t complicated,” she explains. “They are simply nutrient dense whole foods that support metabolism, cellular health, decrease inflammation, and keep your body functioning optimally over time.” Below, she and other experts share the foods they consider “non-negotiables” for building a longer, stronger, and healthier life—along with tips for adding them to your weekly meals.
This Clean, Effective Powder Helps Support Muscle Growth, Endurance, And Recovery
1. Wild-Caught Salmon
When it comes to longevity, omega-3–rich seafood tops Shapiro’s list—salmon, in particular, is a standout. Not only is it delicious, but its powerful fatty acids support heart and brain function, reduce inflammation, and lower the risk of chronic diseases tied to aging. That means better focus, better cardiovascular health, and improved longevity potential over time.
Wild-caught salmon is packed with EPA and DHA omega-3s, vitamin D for strong bones and immune health, selenium for thyroid support, and high-quality protein to keep muscles strong as you age.
Shapiro recommends making salmon a weekly staple. "I recommend 2–3 servings per week. Add it baked, grilled, or air-fried to salads, grain bowls, or pair with veggies for a simple dinner," she says. And don’t stress about finding it fresh. According to Shapiro, "Frozen is just as good as, or often better than, fresh and is more easily available for cooking regularly."
2. Grass-Fed Beef
Protein is essential for your wellbeing, especially when it comes to maintaining muscle mass, which naturally declines as we age. Shapiro says grass-fed beef offers a high-quality source of protein plus longevity-friendly nutrients that support metabolism, energy, and healthy aging. It’s also rich in iron, zinc, and CLA, making it a nutrient powerhouse for anyone looking to preserve strength and vitality.
"High-quality protein is essential for maintaining muscle mass, which slowly declines with age and is strongly tied to longevity," Shapiro explains. Grass-fed beef delivers omega-3s, heme iron for energy, zinc for immune health and skin integrity, B vitamins for energy metabolism, and CLA to support fat metabolism.
Make it a staple! Shapiro suggests "a few 3–4 ounce servings twice weekly." Try it in stir-fries, tacos, meatballs, or simply grilled with roasted vegetables. Keeping some in the freezer is a pro move—"Keeping a stash in your freezer allows for great quality meat anytime you need it," she says. Noted!
3. Crate-Free Pork
Crate-free pork earns is another longevity-supporting food thanks to its complete protein profile and nutrients that power cellular repair and energy production. It contains key micronutrients like thiamin and selenium, which play a role in healthy metabolism and thyroid regulation—two things that often become more important with age.
Shapiro highlights pork for its amino acids and nutrient density. "Pork provides essential amino acids for tissue repair, plus important nutrients for energy metabolism and thyroid function," she explains.
Lean cuts like tenderloin or center-cut chops are ideal choices. Shapiro recommends slow-cooking, roasting, or using leftovers to top salads and bowls. "I recommend keeping great quality crate-free pork cuts in your freezer to allow for healthy meals at any time with proteins you can trust!"
4. Leafy Greens
It's not all about meat—don't forget to eat those greens, too! Dr. Sarah Bonza, MD, board-certified US physician, emphasizes the importance of incorporating leafy greens such as spinach, kale, and collards into your diet for a longer life.
She notes, "Leaves are rich in vitamins, minerals, and antioxidants, and help to fight chronic inflammation and oxidative stress, two factors implicated with aging." These nutrient-packed greens not only support overall health but also promote gut health and aid in controlling blood sugar levels, reducing the risk of chronic diseases that can impact longevity.
We suggest whipping up a big, healthy salad for dinner.
5. Nuts and Seeds
Craving something crunchy? Add these life-lengthening treats to your meals or munch on them as a snack. Nuts and seeds offer a plethora of health benefits, including immune support.
Dietitian Lisa Andrews explains, "Nuts and seeds provide healthy fats as well as selenium and zinc." Selenium acts as an antioxidant, protecting cells against free radicals, while zinc is crucial for normal immune function.
For these reasons and more, adding nuts and seeds to oatmeal, trail mix, salads, or enjoying them as a snack can provide a nutrient boost that may contribute to longevity.
6. Seasonal Fruit
If you're craving something sweet, ditch the added sugar. Instead, reaching for some healthy fruit can be great for your tastebuds and your longevity efforts! Just like vegetables, seasonal fruits provide essential vitamins, antioxidants, and fiber to support a healthy immune system.
Andrews recommends adding berries (which are packed with benefits) to smoothies or cereal, and using citrus fruits in salads or salsa. By incorporating seasonal fruits into your diet, you not only satisfy your sweet cravings but also provide your body with vital nutrients that can contribute to longevity.
