With nutrition, the main thing to think about is staying fit, healthy and being able to perform in the sport or activity you've chosen. Therefore eating a variety of foods, including plenty of fruit and vegetable, will be useful to get the vitamins and minerals your body needs.
Protein (such as seeds, nuts, beans, dairy products, eggs, meat and fish) are useful to help with recovery and repair.
As carbohydrates (such as bread or pasta) are our main source of fuel, these should be used around any exercise or activities especially when it goes over the 60 minute mark.
Fats (such as avocados, nuts and seeds) are also vital for our health, and eating a varied diet should mean you cover all bases with looking after your nutrition.
