best diet for longevity

It is the billion-dollar question. What are the best foods for longevity? What lifestyle choices will increase my chance of a longer life? Here are 7 ways that research has demonstrated potential longevity returns.

1. Community

The book The Blue Zones  looked at clusters of people living over 100, and one of the biggest common denominators was the strong community in each location.

The power of community is hard to measure due to a complex interaction between our neurotransmitters, sense of belonging, purpose, and reduction of stress. To read some fascinating examples, please see this article: Inspiring Effect of Community on Health.

2. Skip a meal once and a while or eat within a 9-12 hour window each day

Most of us will not realistically be able to stick to a caloric restricted diet indefinitely.  But we can rejoice and reap some of the benefits of calorie restriction by intermittently fasting or by condensing our eating window to 9-12 hours each day, with the latter being the easiest to implement and stick to.

Try to eat or drink your last stint of calories no later than 8 pm each night and hold off on anything that requires metabolizing (that includes coffee with caffeine) until 8 am the next day.  This will give you 12 hours of fasting for your body to repair and regenerate.

3. Take a cold shower or (if you are up to it) a cold bath, and hit the sauna

Some studies have shown with mice that as few as 2 exposures to cold each week (we are talking about ~50F bath for 15-20mins) promote health benefits that persist in the body for multiple weeks after the cold exposure discontinues.  Heat exposure in saunas causes the body to release heat shock proteins (HSP), which offer many benefits.  After one exposure, HSP remains elevated in the body for around 48 hours.

With that, we suspect 2-3 times a week may be a sufficient dose and an approach that is easy to maintain. Remember, pay attention to your body and do not overdo it.  We do not recommend “stacking” these stressors, although a cool shower after a sauna may be necessary to cool the body down more quickly so we can return to daily life without sweating profusely.

At The Health Beat, our favorite way to cool down after a sauna session is to drink a cold 750ml Gerolsteiner mineral water while rinsing off in the shower.  This also helps replenish the minerals lots through sweating.  Try to stay away from cold therapy right after weight training, since it may blunt the beneficial muscle-building inflammatory response.

Our recommendation is to focus on heat in the warm months and cold in the winter months.  This more closely mimics the environmental thermal stressors we would have experienced naturally in the past, and also improves our acclimation to those seasons, making outdoor activities more enjoyable (less sweating and overheating in summer and less shivering and chills in the winter!).

4. Exercise: mix it up between aerobic activities and high-intensity training

We pretty much always hear good things about exercise.  The advice here is to mix it up and rotate between endurance (aerobic) type activities like jogging and muscle building high-intensity interval training.  They have both shown enormous health benefits but target different pathways and mechanisms in the body. Again, do not forget to rest.  Going for a walk or hike in nature counts too.

5. Take up yoga and meditation

In addition to reducing inflammation by inhibiting the NF-kB pathway, yoga and meditation also reduce phycological stress in studies.  Meditation even enhances grey matter in the brain. A good strategy would be to slip in these de-stressing activates between other stressors like exercise or do them on alternating days. Yoga, deep breathing techniques, Qi Gong, and mindfulness are examples that would fit this category.

6. The best foods for longevity: diversity

Before we dive into all things phytochemicals, we need to first remind you again of the importance of vitamins and minerals.  Cells, genes, and enzymes need these macro and micronutrients, trace minerals and essential minerals to undertake their complex and essential activities in the body.  We all need to ensure we are getting adequate intake of hard-to-get minerals and vitamins such as Magnesium, Vitamin D,  B-vitamins, Vitamin C, choline, trace minerals (e.g. Boron, Lithium), Selenium, and Zinc.

Recall:  22% of all enzymes require a micronutrient to function (67). Eating a diet rich in phytochemicals is a must, and with conflicting research around supplementing with anti-aging compounds in isolation, a food first strategy is our recommendation.  Aim to increase your intake of a diverse variety of vegetables, fruits, herbs, and spices.  Many foods that are rich in polyphenols tend to have anti-inflammatory effects and also contain many of the compounds identified above.  Some polyphenol-rich foods are:

Cloves Peppermint Star anise Raw cacao
Mexican oregano Celery Fennel Flaxseed meal
Black elderberry Chestnut seeds Dried sage Rosemary
Spearmint Thyme Blueberries Blackcurrant
Capers Olive oil Hazelnuts Pecans
Coffee Tea Black cumin seed Cardamom


If you do a quick search on the internet for these foods, you will notice that Black cumin (nigella sativa) seed oil is touted as a miracle health food.  This may be a stretch from the truth but it does offer some impressive health benefits.  In vivo treatment with black cumin seed oil exerts an insulin-sensitizing action and has also been shown to activate AMPK. Black cumin seed oil contains a phytochemical called thymoquinone, which protects the liver from injury, boosts our bodies master antioxidants glutathione and superoxide dismutase, and inhibits NF-kB activity (94)

Polyphenols can also affect other pathways such as COMT in a negative way.  Catechins are especially troubling for slow COMT, which you will find a ton of in teas (especially green tea), coffee and chocolate; and concentrated berry/grape products such as red wine.  In addition, if you are a slow metabolizer of caffeine, tea and coffee may cause more harm than good.  Fortunately, there are some high-quality decaffeinated varieties available if you still choose to consume these products for their polyphenols.

For tea and coffee, consider the Nutrition Genome Report to identify if your COMT gene needs some extra attention and if caffeine is your friend or foe.

Polyphenols get most of the attention when it comes to health-promoting plant phytochemicals, but terpenes are also very important to consume.  They are especially good at inhibiting the NF-kB pathway and keeping chronic inflammation low (95).  Here are some Terpenoid rich foods (96):

  • Monoterpenes: Lemons, oranges, grapefruit, caraway, bergamot, peppermint, spearmint, dill, tomatoes
  • Diterpenes: Carrots, spinach, pumpkin, broccoli, mango, papaya, cherries, tomatoes, oranges, cabbage, watermelon, lettuce
  • Triterpenoids: Olives, mangos, strawberries, grapes, figs
  • Terpenoid chromanols: Almonds, walnuts
  • Carotenoids: Tomatoes, oranges, carrots, peas, sprouts, greens

Research suggests that for reducing inflammation and for inhibiting the NF-kB pathway, Triterpenoids may be the most beneficial.  Many herbs and mushrooms are high in these compounds including reishi mushroom, ashwagandha, ginseng and boswelia (97).  Reishi mushroom is especially rich in triterpenes; containing more than 100 different types, with 50 of these being new and unique to this mushroom (98).

Another notable mushroom with anti-aging properties is Cordyceps.  Cordyceps enhances the activity of AMPK while also assisting with the hypothalamic–pituitary–adrenal axis (HPA axis) balance and anti-cancer activity. Its ability to activate AMPK is believed to be one of its anti-aging components in the body, along with its anti-diabetic effects.

Cordyceps also inhibit intracellular lipid accumulation and the militaris variety induces fatigue recovery.  These results are primarily attributed to activating AMPK, targeting mTOR pathways and regulating serum hormone level (99). Some additional foods that are colloquially known as “anti-inflammatory” are:

Green leafy vegetables Bok Choy Celery Beets
Broccoli Blueberries Pineapple Salmon / Fish oil
Fermented Vegetables Bone Broth Coconut Oil Walnuts
Chia Seeds Flaxseeds Turmeric Ginger
Buckwheat Tea Garlic Shiitake Mushrooms


An honorable mention goes to the Isothiocyanate phytochemical class and the specific potential of sulforaphane.  Sulforaphane offers a lot of promise since it helps the liver with detoxification, acts as an antioxidant, offer broad-spectrum antimicrobial activity and is a power anti-inflammatory.

Sulforaphane seems to hold promise in the prevention and treatment of nearly all age-related diseases including, but not limited to, cancer, cardiovascular disease, inflammation, dermatitis, cognitive decline, and blood vessel health (100).  Studies show that sulforaphane significantly reduces the activity of NF-kB, so eat your broccoli sprouts (101)! Depending on your gut health, you may also want to consider a probiotic supplement since consuming them activates SIRT and inhibits NF-kB.  Probiotics and a proper gut lining and microbiome play an important role in managing inflammation (102) (103).

7. Sleep, circadian rhythm, and sun

We all know intuitively sleep is important.  It is great that science has verified this intuition, and demonstrated that it effectively and beneficially targets anti-aging pathways.  We recommend that you keep a routine with sleep (bedtime and wake time) and try not to deviate from it by more than 2 hours on the weekend.

It is also important to expose yourself to bright blue (short wavelength) light during the day to ensure melatonin and cortisol are following the proper circadian rhythm dance. It may also be important to aid your body in boosting melatonin levels at night.  This can be done with the consumption of foods that contain melatonin such as wine, cherries, and berries.  Please note that alcohol affects sleep (especially deep sleep), so if you chose to consume it do so with quantities that boost PON1 activity, with your dinner meal and ideally 3-4 hours prior to bedtime.

That same blue light that we want exposure to during the day is detrimental to our circadian rhythm if we are exposed to it after sunset.  Try to limit “screen time” since most devices emit blue light.  If you are on devices or watching TV in the evening, it has been shown that wearing short-wavelength blocking glasses increases nighttime melatonin levels by 58% compared to carrying out the same digital routine in the evening without the glasses (104).

We recommend staying away from melatonin supplements since they can cause dependency and reduce the body’s natural production of this important hormone. Getting adequate sunshine not only enhances our mood but creates Vitamin D and boosts nitric oxide production which activates AMPK.

As a rule of thumb, if your shadow is longer than you are tall, you are not producing Vitamin D from the sun.  Blood Vitamin D levels should be measured to ensure they are in the optimal range and Vitamin D supplementation may be necessary.  As with other recommendations in this article, do not overdo it with the sun since overexposure to the sun can accelerate skin aging, cause sunburns, increase inflammation and increase skin cancer risk.
