Performance Enhancing Nutrition Series Part I: Tart Cherry

Enhancing our sports performance, recovery and whole body health

Tart cherries and tart cherry juice are an abundantly rich source of antioxidants and anti-inflammatory polyphenols. Because exercise causes oxidative stress, inflammation, and muscle damage it has been proposed that these compounds in tart cherries may help both strength and endurance athletes by reducing muscle damage, reducing pain levels, improving recovery, bolstering the immune system, and improving sleep.

Improve Recovery
Improved Sleep Duration & Quality
Bolster Immune System

Dosage and Food Form 
The immediate allure of tart cherries, for me, is that they can be taken in whole food form – we don’t need them to be processed into a supplement. I firmly believe in turning to whole foods first. That is if the researched dose of the beneficial elements of a food can be healthfully obtained through the whole food. And, tart cherries can.
Dose: 50 tart cherries
Frequency: 1-2 times daily
Timing: varies depending on desired benefit.  Research on recovery often gives athletes tart cherries over an acute time period, centered around a competitive event. Typically around 4-5 day prior to and 2-3 days post event. 
Most researchers use the ‘equivalent of 50 tart cherries’ once or twice daily. Naturally, my nutrition nerd curiosity got the best of me and I wondered how the different forms of tart cherries stacked up- by nutrition, cost, and added ingredients. So, here it is:

Tart Cherry Product, Serving Size *Cup Equiv., Calories, Carbohydrates, Fiber Added, Ingredients, Price per serving
Cheribundi Regular 8 oz, 1, 130, 32, 0, Apple juice, $1.63
Cheribundi Light 10 oz, 1 & 1/4, 100, 26, 0, water, Reb A, $2.05
Cherry Bay Orchards, concentrate 4/5 oz,<2 Tbsp, 64,15, 0, $0.50
Dried Tart Cherries, sweetened 46 gm 1/3, 151, 37, 1.2, sugar, oil, $1.53
Dried Tart Cherries, unsweetened 44 gm 1/3, 141, 33, 3.3, $2.00
Tart Cherries, canned in water 151 gm, scant 1 cup, 96, 22, 3.2, water, $1.75
*equal to 50 tart cherries

Please note: the information in the table above is representative of the nutritional value and price of these products as provided by their customer service and sales in Jan 2018. There are many different brands of tart cherry products – this is a small sample of the brands which are easily accessible to athletes with transparent tart cherry concentration information. I purchased all these products – no compensation was provided for including.  

The information provided in the table above are things that, as a dietitian, I feel may weigh into someones choice of using one avenue of cherry consumption vs another. If you are unsure which is best for you and your training, or you’re wondering when you should eat/drink your cherries, contact me.
Concerns or Unknowns
There may be a time during training when we do not want to override our body’s stress response by providing exogenous antioxidant sources  – say during the build up phase of training, where we do not want to blunt the bodies natural physiological adaptations to training. However, more research is needed on this and it may be less of a concern when consuming a whole food product vs a mega dose antioxidant supplement.
Only one study has been conducted on non-land athletes, and it did not show a benefit to consuming tart cherries. This raises the question, are tart cherry compounds less beneficial to athletes who aren’t going through the wear and tear of a land athlete? Is there a differing oxidative stress load in aquatic athletes that may be responsible for the lack of benefit? Perhaps.
Long term benefits? Research hasn’t explored this in depth. It would be interested to see more studies on joint pain and tart cherry intake in athletes over a 3-4 month training period. There is some anecdotal ‘word on the street’ that professional and Olympics athletes are using tart cherries in this manor.
Final Thoughts 
There’s no doubt that the antioxidant and anti-inflammatory components of tart cherries are beneficial to our bodies. Current research shows promise that tart cherries could be an advantageous addition to an athletes diet in various ways. For many athletes, the allure is the proposed alternative of using tart cherries in place of NSAIDs.
With this being consumed in a whole food form, the potential benefits certainly outweigh the very minimal risk. And, when taken at the appropriate times during training, could certainly give a well trained athlete the edge they are looking for.
