What you eat should supply your body with all the nutrients and fuel that it needs to keep it healthy, but this is easier said than done Your nutritional needs depend on many different things including your lifestyle, age, size, gender and state of health. A perfect diet would be one that matches your individual requirements. However, without becoming a trained dietician, deciding what is the perfect diet for you is a daunting task. Luckily, there are some basic food-facts that can start you on your way. The human body needs three major food groups - protein, carbohydrate and fat.
Protein is used as the building blocks of our body tissue.
Carbohydrates and fats, on the other hand, are mostly used as energy. Carbohydrates include sugar, starch and fibre. Sugar is good for short energy boosts whereas starch supplies a slower energy release, and fibre can't be digested at all. Despite the bad press it gets, we do actually need some fat in our diet. Like the essential amino acids, there are some fatty acids that we can't manufacture ourselves and we need them in our diet.
