DAILY ENERGY REQUIREMENTS Food comes via three important components (Macro nutrients) Carbohydrates Fats Protein These components are the only sources of fuel for humans and are found in varying amounts of different foods.

Carbohydrates 2 main groups of carbohydrates commonly called starches and sugars 1. Complex carbohydrates- starches 2. Simple carbohydrates- Simple sugars Carbohydrates are a great source of energy Complex carbohydrates are a lot healthier. They supply energy but also have vitamins, minerals and fibre. Eg potatoes, rice, bread, pasta and other cereal foods. Simple Sugars offer energy but have fewer vitamins and minerals and little fibre. Examples table sugar and maple syrup. Hidden very well in common food e.g. chocolate, soft drink, ice cream and confectionary These foods are extremely high in energy however this is excess energy not needed by the body and is quickly converted into fat

Fats Fats generally come in 2 forms 1. Saturated and 2.Unsaturated. Fats are important to the body.
