Bananas are a Real Food Option for Runners.

An encouraging move towards a FOOD FIRST approach is highlighted in a recent study published in 2023.Many athletes are interested in a food first approach, because food is seen to be a more cost-effective choice than sports products, and carbohydrate whole foods offer wider nutritional benefits, as they include other nutrients e.g., vitamins, minerals and fibre.

Potassium

An average banana contains 400-420mg of potassium which is approx. 9-12% of the recommended daily intake of potassium which ranges from 3500-4700mg per day for an adult.

As an endurance runner we tend to sweat and as a result lose minerals (also known as electrolytes) such as potassium, sodium and magnesium which may lead to an electrolyte imbalance. This in turn can lead to muscle cramping in our legs or feet, or side stitches and can influence stomach cramps/diarrhoea.

A banana will contribute to potassium status but don’t forget to include potassium rich foods in your everyday diet and and adding food and drinks to your pre/during/post nutrition plan to support electrolytes will be helpful.
