Essential nutrients There are seven essential nutrients that we must include in our diet, in order to remain healthy. These are listed below. In this series of lessons, we will learn about each essential nutrient.

Carbohydrates The main function of carbohydrate foods is to provide energy. Carbohydrates are made up of building blocks of glucose and other simple sugars. Glucose is the main energy source used in the human body. Carbohydrates provide us with approximately 4 calories of energy per gram. Carbohydrate foods are often a rich source of fibre, vitamins and minerals. NUTRITION AND HEALTHY EATING
Carbohydrates There are three different types of carbohydrate in the human diet. Starchy Sugars Non-starch carbohydrates Sugar polysaccharides Rice Honey Pasta (NSP)/fibre Treacle Cereals Syrup Vegetables Bread Jam/marmalade Fruit Beans/pulses Milk sugar (lactose) Noodles NUTRITION AND HEALTHY EATING
Carbohydrates You can see the carbohydrate-rich foods on the Eatwell Guide – fruit and vegetables (the NSPs) are in the green section, and starchy carbohydrates are in the yellow section. Foods high in sugar are not included in a health diet, but are added in small amounts, shown in the bottom left corner. NUTRITION AND HEALTHY EATING
Do you think you can find carbohydrates in your diet? Using the Essential Nutrients worksheet, write down a typical breakfast, lunch and tea that you often eat – it could be what you ate today, or yesterday, or a favorite meal. Once you’ve done that, see if you can find examples of the following types of carbohydrate, and make a note of them. • Star Starchy c hy carb arboh ohydr drates tes • Non Non-star starch ca h carbo rbohy hydr drates ( tes (fibr fibre-ri rich h foo oods) ds) • Su Suga gars NUTRITION AND HEALTHY EATING
Carbohydrates All types of carbohydrate are made up of simpler units of sugars, known as monosaccharides. Sugars, fruits and sweet tasting foods are made of simple sugars (monosaccharides and disaccharides), and starchy carbohydrates and fibre-rich foods contain chains of sugars, called polysaccharides.

Carbohydrates It is recommended that approximately 50% of our diet is made up of carbohydrate foods, but this should come mostly from starchy carbohydrates, and vegetables and fruit (the fibre, or NSPs). No more than 5% of our carbohydrate intake should come from added sugar. Starchy carbohydrates (also called complex carbohydrates) take longer to digest and provide energy for longer; sugars are absorbed quickly and give a quick spurt of energy.
