What is Protein? KEY FACTS • Meat- fish and poultry - High grade proteins • Full of nutrients • Protein is good for Growth and repair of muscles, tissues and organs – helps children grow • Lack of protein – kwashiorkor • Protein is made up of amino acids • Some proteins have all the essential amino acids HBV( meat, fish, eggs, soya beans) – some have some of the essential amino acids LBV and need to be combined to get all the essential amino acids ( peas, lentil and bean).

Sources of Protein?

What is protein made up of? • A macronutrient – needed by all animals and humans • The molecules are made up of building blocks - amino acids • 20 different amino acids • Found in a combination of proteins from meats to beans and pulses

Vegetarian alternatives – meat replacements What are these? Foods • Vegetarian ? ? • Vegan ? ? • Tofu – soya means – can be used in desserts or usually stir fried • TVP- Textured vegetable protein soya beans sausages, burgers, ready meals • They need to ensure they get the right balance of proteins from replacement foods. Combining LBV foods to ensure all essential amino acids present. • Quorn _mushroom like fungus and egg white – mycoprotein – chunks, mince, fillets • Most made to look and taste like real meat • Can be marinated before cooking to give more taste

Protein alternatives • Tofu (bean curd) – made from treated soya milk – • Tempeh – made from fermented soya beans • TVP (textured vegetable protein) – made from soya bean flour (after soya oil removed • Mycoprotein (quorn) – made from high protein fungus

When you eat protein – what happens • Your body breaks the protein down into amino acids. It body breaks up (digests) the molecules • It uses them to build new proteins • Your body then uses them to make muscle and repair- repair what? ? ? • It breaks it down into individual amino acids • It then makes new protein molecules for our body to digest

Functions of protein in the body 3 main: • Growth – from baby to adult then when this growth has completed its phase – hair, nails etc • Repair – helping recovery after an injury or operation - also replace certain parts of the body regularly ie skin cells and red blood cells • Energy – though your body prefers to get it from carbohydrates

Why are proteins important? • Some of the 20 amino acids the body cannot make • We need to get these from food that we eat • These are called Essential Amino Acids • 8 are needed by children and adults • Younger children 2 more

What else does protein do? • Hormones – make you grow and reproduce • Enzymes – digest your food • Antibodies – helps the immune system fight infections

Essential amino acids • Foods that contain ALL the essential amino acids are called HBV (high biological value) • Foods that contain some of the Essential Amino Acids are LBV ( low biological value) • Complementation of proteins is when you combine a mix of LBV’s to ensure you get the right essential amino acids to make it HBV • Think of a LBV meal and make it HBV • How would you make a meal high in protein? • Name an example

HBV and LBV HBV LBV • Meat • Quinoa • Soya beans • Eggs • Dairy foods • Fish • Nuts • Beans and lentils • Seeds • Gelatine sheets and powder • Sorghum

Examples of complementation of protein meals pictures

Deficiency of protein Effect Why? • Children will not • The body needs the right amount grow properly and combination pf and may not nutrients to grow reach full height effectively • Loss of hair • Skin and nail in poor condition • Hair is made of protein – as we can live without hair the body will use protein it gets for something more important in the body • These contain protein and will be weakened by not having enough protein

Deficiency Effect Why • Will easily develop infections • We need protein to boost and maintain our immune system, not having enough will weaken it. • Not able to digest food properly • A deficiency causes changes in the digestive system – various nutrients cannot be absorbed into the body

Excess protein • Protein contains different chemical elements • Nitrogen is one of them • Too much nitrogen is dangerous and therefore removed from our body on our urine • The liver and kidneys have to work harder to expel the excess nitrogen • The stress could harm them
