1 Carbohydrates
1.1 Carbohydrates are a source of energy. Foods rich in carbohydrates include:-Bread,Pasta,Rice,and Breckfast Cerals,as well as sugar. Simple carbohydrates are known as sugars,and this energy is released quickly. Complex carbohydrates are starchy foods such as bananas,chickpeas,nuts,potatoes and whole grain cereals. These foods release energy slowly and they are digested,which makes your energy levels more stable. For a healthy siet,eat more of the complex carbohydrate foods.
2 Protein
2.1 Protein is needed for growth and repair,and is also a source of energy. Protein-rich foods include:-Meat,Fish,Chicken,Eggs,Beans and nuts.Vegitarians obtain their protein from foods such as pulses:-peas,beans,lentils,soya products,grains,pasta,brad,nuts and seeds. a balanced diet should contain all the proteins the body needs.
3 Fibre
3.1 Fibre is needed to keep the gut healthy and prevent constipation. Fibre is not digested when we east it.In the UK most people eat far too little fibre,on average about 12 grams a day or less. ideally adults should aim for 18 grams a day,or a little more.
3.1.1 All plant-based foods contain fibre. Good sources of fibre are fruit and vegetables,wholegrain rice and pasta,wholemeal bread,many breckfast cereals,nuts,seeds and bran. The food lable shows the amount of fibre in a food product and you can use a nutrional analisis program to help
4 Fats
4.1 Fat is a good source of energy and a source of the essential fatty acids that the body cant make itself,and the fat helps the body to absorb some vitamins. All fat is high in calories,so if you are watching your weight,you should limit your fat intake.The total amount of fat you eat should make up no more than 30% of your calories from food.Foods high in fat include:-butter,oil,margarine,and fried food.
4.1.1 There are two types of fats: Unsaturated fats and Saturated fats Eating too much of saturated fat can increase blood cholesterol levels and the risk of coronary heat disease. The healthier type of fat is unsaturated fat which can improve cholesterol levels. Solid fats which contain saturated fat include butter and ghee (clarified butter),lard and coconut cream. replace saturated fats in cooking with rapeseed or coorn oil,which contain unsaturated fat or just use less of them. fats and oild are liquid at room temperature are more likely to be products high in saturated fat include meat,sausages,pies,hard cheese,cakes,pastries,biscuits and food containing coconut or palm oil.
5 vitamins and minerals are called micronutrients,which means they are needed in smaller quantities than the macronutrients-protein,carbohydrate and fat. if you eat a variety of foods and a balanced diet you will get most of the nutrients you need.
6 Vitamins
6.1 There are two groups of vitamins:fat-soluble and water soluble. the fat- soluble vitamins-A,D,E and K-Desolve in fat and are stored in your liver. Vitamin A-Maintains healthy eyes,skin and hair Vitamin D-helps form strong bones and teeth. Fat-Soluble vitamins are found in animal fats such as butter and lard,vegetable oils,dairy foods and oily fish.Margarines can have vitamin A and D
6.1.1 The water-soluble vitamins-C and the B-complex vitamins-dissolve in water so that your body can absorb them. Your body can't store these vitamins and any vitamin C or B that your body doesn't use is passed out in your need a supply or these vitamins everyday. Vitamin C is required for the structure and maintenance or blood vessels,cartilage,muscle and bone. the B group of vitamins help convert food to energy and also help to build healthy nerve tissue. these vitamins are found in fruit,vegetables and grain.
7 Minerals
7.1 Minerals are found in the soil and water,and pass into plants and animals that we eat for food.your body needs small amounts of minerals to grown and to stay healthy. minerals are necessary for three reasons: building strong bones and teeth controlling body fluids turning food into energy. important minerals include:calcium,iron,magnesium,phosphorus,potassium and sodium.
8 Phosphorus
8.1 Phosphorus is also essential for healthy bones and teeth and is found in red meat,dairy foods,fish and bread
9 Iron
9.1 Iron helps to make red blood cells which carry oxygen around the body.Eat food rich in Vitamin C at the same time as you eat food containing non-meat sources of iron to help the body absorb the iron.for example: frink orange juice with fortified breckfast cereal.
9.1.1 good sources of iron include liver,meat,beans,nuts,dried,fruit,whole grains,fortified breckfast cereal,soybean flour,and most dark green leafy vegetables.
10 Calcium
10.1 Calcium is essential for the healthy growth and maintenance of teeth and bones and helps blood clotting and muscle contraction. Good sources of calcium include,Milk,Cheese,,and other dairy products,green leafy vegetables,soya beans,tofu,and soya drinks with added calcium
