Experts Reveal the Top 10 Foods to Combat Aging

While time continues to move forward, scientific studies suggest that we can slow down the physical signs of aging. One proven method is adopting a nutritious diet, which has been shown to enhance longevity.

"Focusing on the plant-based world—such as fruits, vegetables, beans, nuts, seeds, whole grains, herbs, spices, and tea—is a great starting point," advises Wendy Bazilian, DrPH, MA, RDN. However, she emphasizes that longevity isn't just about living longer but living better. "Most people aim for a long and healthy life, full of vitality and activity, rather than simply reaching a specific age," Bazilian explains. Words worth remembering.

How to Add Anti-Aging Foods to Your Daily Meals

Be cautious of trendy wellness foods and miraculous products promising to reverse aging. "Many so-called 'superfoods' do offer nutritional benefits," says Dr. Bazilian. "However, while research supports their role in health and disease prevention, I believe it's not sufficient on its own."

Incorporate these foods into your daily routine

According to her, for a food to truly impact health, it must be consumed consistently and in sufficient quantities. "Occasional consumption or small portions won't yield significant benefits. It's the consistent, often daily, intake of these foods that contributes to aging gracefully, anti-aging, and longevity."

What defines an anti-aging food?

Bazilian explains that for a food to be considered anti-aging, it must be nutrient-rich, research-supported, easily accessible, versatile, and appealing. Keeping these criteria in mind, here are the standout foods known for their ability to fight premature aging.

1. Blueberries

Blueberries are packed with vitamin C, fiber, and antioxidants. Extensive research highlights their benefits in supporting cognitive function, heart health, reducing cancer risk, and more, according to Bazilian.

"The deep blue hue of blueberries comes from anthocyanin, a powerful phytochemical and antioxidant. These nutrients not only combat oxidative aging but also enhance cellular protection and skin health through their vitamin C content."

2. Walnuts

Walnuts are a powerhouse for promoting longevity. A 2020 study revealed that women who regularly ate nuts, especially walnuts, during midlife were more likely to experience healthy aging compared to those who didn't. (Healthy aging was characterized by the absence of chronic diseases, memory issues, physical disabilities, and maintaining mental health after 65.)

Walnuts are also crucial for heart health. "The groundbreaking research on walnuts and cardiovascular health was published over 25 years ago in the New England Journal of Medicine, and since then, numerous studies have reinforced their benefits," explains Bazilian.

A comprehensive review of 26 heart health studies found that walnuts help reduce total cholesterol (especially LDL "bad" cholesterol), lower triglycerides, support healthy blood pressure, and are rich in anti-inflammatory phytochemicals.

Cognitive health is a cornerstone of longevity: Numerous studies highlight that walnuts, with their unique blend of nutrients and phytochemicals—such as omega-3 fats, fiber, protein, polyphenols, and essential vitamins and minerals—can help delay cognitive decline, slow its progression, and support brain health as we age. "This is a major anti-aging objective," Bazilian notes. "Living well and living long go hand in hand, and cognitive health is essential."

3. Tea

As the second most consumed beverage globally after water, tea offers a wealth of anti-aging benefits. It’s hydrating and rich in antioxidants like EGCG, catechins, flavonoids, and theanine, which combat inflammation and promote overall health.

"The most extensive research on tea consumption and heart disease suggests that drinking two to three 8-ounce cups of unsweetened green or black tea daily could reduce the risk of heart disease-related mortality by approximately 8 to 12 percent," says Taylor C. Wallace, PhD, CFS, FACN.

"The study also highlights that older adults (65 and above) may experience the greatest benefits, with each cup of tea potentially reducing heart disease mortality risk by 10 percent." Regular tea consumption supports heart health by reducing total cholesterol and LDL levels, as well as slowing coronary artery calcium buildup compared to non-tea drinkers. Adding unsweetened tea to your daily routine is a simple way to potentially extend your lifespan.

4. Beans and Legumes

Beans uniquely belong to two food groups: carbohydrates and protein. "They are a staple in the Mediterranean diet, renowned for its health benefits and prevalent in regions known for longevity and vitality," explains Bazilian.

"Legumes are a powerhouse of plant-based protein, linked to reducing the risk of chronic diseases and enhancing overall health and longevity. They are packed with phytonutrients, vitamins, minerals, and fiber, which support heart and gut health, stabilize blood sugar, lower cancer risk, aid in weight management, and more."

Beans are incredibly versatile. Whether kidney, black, red, fava, garbanzo, or cannellini, they can be added to soups, salads, stews, lasagna, or casseroles. They can also be mashed with herbs and spices to create a flavorful dip. Even canned beans, when low in sodium and rinsed (removing 40 to 50% of the sodium), are convenient, affordable, and nutrient-dense.

5. Herbs and Spices

"Herbs and spices are like an anti-aging superfood group," Bazilian notes. "Their primary role is to enhance flavor, which is the top factor influencing food choices, even more than convenience or health. By making nutritious, anti-aging foods taste amazing, they serve a dual purpose."

Essentially, herbs and spices elevate the taste of healthy foods like vegetables, fish, and plant-based proteins—while helping us cut back on salt and added sugar, which supports healthy aging and reduces inflammation.

Emerging research highlights the phytochemical, anti-inflammatory, and other unique benefits of herbs and spices. They are also a key component of the Mediterranean diet, closely linked to longevity and overall well-being.

Some of our top picks? Ginger (famous for its anti-inflammatory and anti-nausea properties), rosemary, cinnamon, turmeric (known for its strong anti-inflammatory effects), and red pepper.

6. Pasture-Raised Eggs

Eggs are rich in a lesser-known but essential nutrient. "Choline is vital for maintaining cognitive health and sharp memory as we age," explains Tami Best, MS, RDN, IFNCP. "Pasture-raised whole eggs are an excellent source of this nutrient."

A single pasture-raised egg provides 147 mg of choline, covering roughly 27% of the daily recommended intake for adult women. The yolk, where most of the choline is found, should be included for maximum benefit.

"Some healthcare providers might suggest a choline supplement since it can be challenging to meet the required intake through diet alone," Best notes. Choline is also present in foods like chicken, shrimp, peas, potatoes, and mushrooms.

Research shows that pasture-raised eggs contain higher levels of vitamin A, vitamin E, and omega-3 fatty acids compared to eggs from caged hens—nutrients essential for maintaining health as we age.

7. Pears

A 2020 study in Neurology found that consuming fruits, vegetables, tea, and wine positively impacted cognitive health in participants of the Rush Memory and Aging Project. Higher intake of flavonols, present in pears, leafy greens, broccoli, oranges, tomatoes, beans, olive oil, tea, and wine, was linked to a lower risk of Alzheimer's-related dementia.

8. Cruciferous Vegetables

Cruciferous vegetables like kale, Brussels sprouts, and broccoli are rich in glutathione, a vital antioxidant. "Antioxidant-rich foods help reduce damage from toxins that accumulate over time and accelerate aging," explains Best. "Glutathione, our body’s primary antioxidant, aids the liver in detoxification by neutralizing harmful free radicals."

Cruciferous vegetables are also a source of sulforaphane, a compound known to extend cellular lifespan and protect against neurodegeneration.

9. Pasture-Raised or Wild-Caught Proteins

Ensuring adequate protein intake is crucial as you age, according to Best. "From around age 35, natural muscle loss called sarcopenia begins. Consuming high-quality protein with every meal can help slow this aging process."

Best suggests consuming 25 to 35 grams of protein daily, distributed evenly throughout the day. "Our bodies process protein more efficiently in smaller, frequent doses," she explains.

Opt for high-quality protein sources like pasture-raised, organic meats and dairy, wild-caught seafood, and non-GMO soy products such as edamame, tofu, and tempeh. Similar to eggs, pasture-raised meats and dairy are richer in antioxidants and healthy fats compared to conventionally raised options.

10. Avocados

Avocados are a great source of glutathione, a crucial antioxidant for liver health, according to Best. For those worried about skin aging, avocados contain carotenoids, which are known to enhance skin elasticity and reduce visible signs of aging.

Avocados are also packed with fiber, vitamin K, and healthy fats that support heart health. Additionally, their high vitamin E content can boost cognitive function.
