Starter – protein card sort using BHF cards https://www.youtube.com/watch?v=ywH2_KfrOUc

In groups of 4-5 find all of the protein cards in the BHF packs.Sort them into Animal HBVPlant LBVIs there a difference in the FAT/SAT FAT content between HBV and LBV? Can you explain why?

What is Protein?

KEY FACTSMeat- fish and poultry - High grade proteinsFull of nutrientsProtein is good for Growth and repair of muscles, tissues and organs – helps children growLack of protein – kwashiorkorProtein 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 acids20 different amino acidsFound in a combination of proteins from meats to beans and pulses

Protein in purple

Vegetarian alternatives – meat replacementsWhat are these?

Vegetarian ????Vegan ????They need to ensure they get the right balance of proteins from replacement foods. Combining LBV foods to ensure all essential amino acids present.FoodsTofu – soya means – can be used in desserts or usually stir friedTVP- Textured vegetable protein - soya beans - sausages, burgers, ready mealsQuorn _mushroom like fungus and egg white –

mycoprotein

– chunks, mince, filletsMost made to look and taste like real meatCan be marinated before cooking to give more taste

Protein alternativesTofu (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 removedMycoprotein (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 moleculesIt uses them to build new proteinsYour body then uses them to make muscle and repair- repair what???It breaks it down into individual amino acidsIt then makes new protein molecules for our body to digest

Functions of protein in the body3 main:Growth – from baby to adult - then when this growth has completed its phase – hair, nails

etcRepair – helping recovery after an injury or operation - also replace certain parts of the body regularly ie skin cells and red blood cellsEnergy – 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 eatThese are called Essential Amino Acids8 are needed by children and adultsYounger children 2 more

What else does protein do?Hormones – make you grow and reproduce

Enzymes – digest your foodAntibodies – 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 HBVThink of a LBV meal and make it HBVHow would you make a meal high in protein?Name an example

Examples of complementation of protein meals pictures

Deficiency of proteinEffect

Children will not grow properly and may not reach full heightLoss of hairSkin and nail in poor condition Why?The body needs the right amount and combination pf nutrients to grow effectively 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

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

Excess proteinProtein contains different chemical elementsNitrogen is one of them

Too much nitrogen is dangerous and therefore removed from our body on our urineThe liver and kidneys have to work harder to expel the excess nitrogenThe stress could harm them
