Nutrients
Water, Fats, Carbohydrates, Minerals, Protein & Vitamins
1 of 16
Macronutrients
Proteins, Fats & Carbohydrates. These are needed in relatvley large quantities and form the bulk of our diet.
2 of 16
Micronutrients
Vitamins & Minerals. Found in food and are vital to health but are required in very small amounts.
3 of 16
Protein
Growth, Repair of body tissue, renewal of cell proteins. Enzymes, vital for metabolism, are composed of proteins. Hormones composed of protein, secondary source of energy.
4 of 16
High biological value (HBV)
Contain all essential amino acids. Come from animal sources (meat, fish, poultry and dairy) vegetable source, soya (soya mince, textured vegetable protein and tofu. Quorn.
5 of 16
Low Biological Value (LBV)
Vegatble sources of protein include cereals, peas, beans, pulses, nuts & seeds. They dont contain all essential amino acids. Easily combined in a meal or product to provide all amino acids. This is called food combining or complementary proteins.
6 of 16
Fat
Used by the body for energy and also form part of the structure of cells. Stored under the skin. Kidneys are protected by a layer of fat. Fat is a source of fat-soluble vitamins A, D, E and K. Gives food texture and flavour. Feeling of satiety.
7 of 16
Sources of fat
Animal and plant sources. Fruits, avocado pears, olives, nuts & pulses, peanuts and walnuts, seeds, sesame, sunflower & soya. Animal - meat, lard and suet, milk, butter, cheese & cream, fish, particularly oily fish, tuna, salmon and sardines.
8 of 16
Carbohydrates
Provide the body with energy for physcial activity, provide the body with energy to maintain bodily functions. Provide dietary fibre (non-starch polysaccharide) to help digestion. They sweeten and flavour foods
9 of 16
Starches
Found in grain products, bread, rice, cereals and pasta. Broken down slowly into simple sugars by the digestive system to provide energy, adds bulk to our diet, provides a feeling of fullness, excess is converted into fat.
10 of 16
Fibre (NSP)
Non starch polysaccharide is the non-digestable cellulose found in plant foods. It passes straight through the digestive systems, absorbing moisture and providing bulk
11 of 16
Dietary Fibre
Holds water and keeps the faeces soft and bulky. Helps prevent various bowel disorders, including constipation, bowel cnacer, appendicitis and haemorrhoids (piles) Can help people to control their body weight & can HF diets lead to low cholesterol.
12 of 16
Vitamins
To maintain health, help prevent diseases such as beri beri and rickets. Regulate repair of body cells, help combat ageing process, help process carbohydrates and release energy in the body.
13 of 16
Vitamins
Fat soluble A & D - can be stored in the liver and used when needed. Water soluble vitamins dissolve in water, they include the group B & C, these are not stored in the body, so foods that contain vitamins need to be eaten regularly.
14 of 16
Minerals
Micronutrients - body building (bones & teeth), control of body processes, especially the nervous system, essential part of body fluids and cells, form part of enzymes and other proteins necessary for the release of energy.
15 of 16
Water
helps regulate the bodys temperature. Sweat evaporates and cools us. Without this we would get heat stroke. Helps kidneys flush out harmful excess or foreign substances from our blood. transports nutrients, oxygen and carbon dioxide round the body.
