The best foods and longevity supplements to improve your healthspan

Looking for the secret to longevity? Incorporating these nutrients into your diet can help you live a long, healthy life. Here are the top science-backed foods and longevity supplements to help improve your healthspan.

Aging. It happens to everyone, yet few of us are truly comfortable with getting older. While no single food will add years to your life, eating a balanced, nutrient-dense diet filled with fiber, vitamins, and antioxidants can help you stay on top of your health and look and feel your best year after year. But could supplements also help extend your life and improve your healthspan?

Here’s what science has to say about foods and supplements that can increase longevity and keep you looking (and feeling) youthful. But before we get started, let’s first examine what longevity and healthspan mean so we can better understand how nutrition plays a role.

Healthspan and longevity definition

According to experts, longevity describes the ability to live a long life beyond the average lifespan, whereas healthspan is defined as the length of time that someone is healthy—not just alive [


]. As such, these two terms are often associated with living a long and healthy life, free from diseases, and maintaining physical and mental well-being.

The best foods to improve your healthspan

Studies continue to show that what you put on your fork can make a significant impact on your healthspan and longevity. But in addition to longevity supplements, what else can you do to improve the odds of reaching triple digits?

To answer this question, we have turned to science to unveil the best anti-aging foods. From curcumin to magnesium, here are some of the best foods to consider adding to your diet.

assortment of nuts in a bowl


Whether you enjoy cashews, walnuts, or almonds, these nutrient-dense morsels are packed with healthy fats, protein, and fiber, which promote heart health, satiety, and laxation. Eating nuts regularly has been shown to reduce the risk of obesity, hypertension, diabetes, and cardiovascular disease - the latter of which is the leading cause of death in adults in the United States [



In addition, recent evidence has shown that consuming an additional 5 g of nuts/day is associated with 6% and 25% lower risks of pancreatic and colon cancers, respectively, and a 4% lower risk of overall cancer mortality [



And while nuts, in general, have a variety of longevity benefits, we can take a closer look at a few different nuts to see what they have to offer. 

For example, almonds have been shown to improve glycemic control and insulin resistance, raise HDL (“good”) cholesterol, and support weight loss [




]. Walnuts provide similar benefits and contain omega-3 fatty acids, which help fight inflammation, support cognition, and promote heart health [



To reap these health benefits, enjoy nuts raw or roasted, blended into nut butter, or sprinkled on cereal for a crunchy, nutritious snack. 

assorted berries in a white bowl


Don’t be shy about eating the rainbow. Blueberries, strawberries, raspberries, blackberries, and cranberries are powerful nutrient gems that are low in calories and rich in antioxidants, vitamins, minerals, fiber, and other bioactive compounds to fight inflammation [





Emerging evidence further suggests that the bioactive compounds in berries help protect against chronic diseases (such as cardiovascular disease, cancer, Alzheimer’s, and other disorders) and improve your healthspan [



Other health benefits include:

  • Vitamin C (found in blueberries and strawberries) can regulate collagen development, helps skin remain firm, and may decrease skin wrinkling [






    ]. Conversely, reduced collagen production can result in saggy skin and increased wrinkles [



  • Improved bone and heart health [





  • Positive impact on insulin sensitivity, oxidative stress, and inflammatory markers [



  • Decreased systolic blood pressure (found with increased strawberry consumption) [

Cruciferous vegetables

Broccoli, cauliflower, brussels sprouts, kale, and cabbage are all members of the cruciferous vegetable family, a class of veggies that may help protect against various chronic diseases. 

Sulforaphane is present in broccoli, cabbage, and cauliflower and has been shown to have antioxidant and antitumor properties [


]. Several observational studies have demonstrated an inverse relationship between cruciferous vegetable consumption and cardiovascular disease [


]. In addition, research indicates that high intakes of cruciferous vegetables may help reduce your risk of colorectal and gastric cancers by as much as 8% and 19%, respectively [



So, go ahead and get cooking with cruciferous veggies to promote longevity. From soups and salads to stir-fries and smoothies, there are dozens of tasty options to include on your menu.

Whole grains

Studies have found a correlation between fiber consumption and all-cause mortality, as a high-fiber diet is associated with lower concentrations of serum inflammatory biomarkers [


]. Research also shows that soluble fiber also helps reduce total and LDL (“bad”) cholesterol levels, as it binds to cholesterol particles in the intestine and prevents them from entering the bloodstream [



For heart health benefits, aim to eat 30-40 g of fiber-rich foods per day, 5-10 g of which should come from soluble fiber [


]. Studies have found that soluble fiber (found in oats, beans, and barley) can help reduce your risk of heart disease by absorbing cholesterol in the GI tract and lowering total and LDL cholesterol levels by 5-10% [

Avocados are packed with fiber, monounsaturated fatty acids, vitamins K and E, potassium, and magnesium, all of which support cardiovascular health, weight management, and healthy aging [



Furthermore, studies have shown that eating avocados can help lower LDL (“bad”) cholesterol, improve glycemic control, and reduce the risk of metabolic syndrome, making them a delicious option to increase longevity and promote youthfulness [

lentils, chickpeas, and other beans and legumes separated into bowls

Beans and legumes

Beans and legumes (such as chickpeas, lentils, kidney beans, and black beans) are nutrient powerhouses that may help protect against colon cancer, diabetes, and heart disease, all of which can contribute to increased mortality [


]. Studies also show that beans and legumes can lower cholesterol, triglycerides, and blood pressure (all of which benefit heart health), increase insulin sensitivity and lower HbA1c (which provide anti-diabetes effects), and positively impact gut health by increasing microbiome diversity and reducing inflammation [



You can enjoy these little morsels in soups, stews, salads, skillets, and even desserts.


As you age, it’s important to pay closer attention to nutrients that promote a long, healthful life. Eating a balanced, nutrient-dense diet filled with nuts, berries, cruciferous vegetables, whole grains, beans, and avocados can help you offset your risk of chronic disease, manage weight, boost skin health, and prevent nutrient deficiencies.
