Back on track 

With gyms and pools all now re-opened, we have been able to get our health and fitness routines going again. But whether you are just starting back up, or are at the top of your game, it’s probably about time to get in the know about how berries, or more specifically the nutrients they contain, can support your general health and also help with your performance or post-workout recovery.

Can berries really help?

Fruit and vegetables in general have the potential to benefit performance and recovery, because of the essential nutrients they contain; including numerous vitamins, minerals and other compounds that can keep the body in tip-top condition. Specific compounds, anthocyanins, found in many fruits and vegetables have gained a lot of attention in sport and exercise research. Anthocyanins are the pigments that give plants their red, blue and purple colouring - so you guessed it, many berries are packed full of them.

So what’s the deal with anthocyanins?

In sporting events where the smallest difference can mean first or second place, any marginal advantage could give you your competitive edge and that’s why berries and other anthocyanin-rich foods are being researched. So what is the science behind them? 


Anthocyanins can act as antioxidants and many have anti-inflammatory properties. They have been shown to improve muscle function and reduce fatigue, factors that can help with performing your best during exercise. Interestingly some studies suggest they can improve fat oxidation and blood circulation during exercise – which means they have the potential to positively impact longer distance endurance performance [1]. Although we don’t know the exact timing, anthocyanins are most abundant in your bloodstream soon after consuming them, so taking them approximately 1-2 hours before exercise is probably the best plan to boost your performance [2].


Exercise, particularly of a strenuous nature, can result in muscle damage and soreness. While some amount of damage may be inevitable and necessary to adapt and improve, being able to recover quicker and get back to it may also be beneficial. A number of studies have shown foods such as berries and cherries might be able to lessen muscle damage, reduce levels of soreness, and ultimately enhance recovery potentially via their antioxidant and anti-inflammatory effects (which have been proposed to be attributable to their high anthocyanin content) [3-6].

I’m not an Olympian!

Good news: you don’t have to be going for gold to benefit from the power of berries.

Amongst other health benefits, a higher intake of anthocyanin-rich foods is thought to be helpful for many aspects of health that include weight maintenance [7], lowering cholesterol levels and blood pressure [8]. There aren’t many studies yet, but in those where exercise and these foods are combined, anthocyanins might complement the health benefits, when compared to exercise alone. For example, exercising individuals given 150 g of blueberries for 4 weeks had less “bad” (LDL) and more “good” (HDL) cholesterol than those who just did exercise [9]. In another study, individuals were fed a high-fat meal in the morning with or without 60 ml of tart cherry juice. It was found that they had lower triglycerides if they had exercised the day before with the juice compared to exercising without the juice [10]. These data are exciting because we already know exercise and a healthy diet go hand-in-hand for better health, but it would appear that anthocyanins may boost the health benefits of exercise, as well as performance.


Whether you are a gym bunny, athlete or even none of the above, berries can still help keep you healthy and also could be beneficial for your performance and recovery.
