Toda​y's Objectives

by the end of this lesson students will be able to : ​

  1. Identify two (2) food sources high in protein needed in the human diet with 80% accuracy.

  2.     State two (2) elements that make up proteins in the body with 80% accuracy.

  3.  Differentiate between high biological and low biological value protein available for human consumption with 80% accuracy.

Objective One ​

​Identify two (2) food sources high in protein needed in the human diet with 80% accuracy.

5

Some food sources of dietary protein include:

  • lean meats – beef, lamb, veal, pork, kangaroo

  • poultry – chicken, turkey, duck, emu, goose, bush birds

  • fish and seafood – fish, prawns, crab, lobster, mussels, oysters, scallops, clams

  • eggs

  • dairy products – milk, yoghurt (especially Greek yoghurt), cheese (especially cottage cheese)

  • nuts (including nut pastes) and seeds – almonds, pine nuts, walnuts, macadamias, hazelnuts, cashews, pumpkin seeds, sesame seeds, sunflower seeds

  • legumes and beans – all beans, lentils, chickpeas, split peas, tofu.

Some grain and cereal-based products are also sources of protein, but are generally not as high in protein as meat and meat-alternative products.

  1. ​Amino acids are molecules that combine to form proteins.

  2. Amino acids and proteins are the building blocks of life.

  3. Th​e body need 22 Amino acids.

What are Amino Acids?

13

Fill in the Blank

Amino acids are molecules that combine to form __________

14

media

When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body:

  • Break down food

  • Grow

  • Repair body tissue

  • Perform many other body functions

Amino acids can also be used as a source of energy by the body.

3 Groups of Amino Acids

  1. Essential Amino acids

  2. Nonessential Amino acids

  3. Conditional Amino acids

Essential amino acids cannot be made by the body. As a result, they must come from food.

Fill in the Blank

Essential amino acids cannot be made by the ______.

As a result, they must come from ______.

19

Nonessential means that our bodies can produce the amino acid, even if we do not get it from the food we eat.

NONESSENTIAL AMINO ACIDS

Fill in the Blank

Nonessential means that our bodies can produce the ___________, even if we do not get it from the food we _____

21

Conditional amino acids are usually not essential, except in times of illness and stress.

High-quality protein is also referred to as “complete protein

A complete protein contains all the necessary amino acids for a nutritional protein-based meal.

High Biological Value Proteins

Low biological value (LBV) proteins are missing one or more of the essential amino acids we need. They're only found in plant sources e.g. peas, lentils, nuts, seeds and most beans, and in smaller amounts in vegetables like spinach and broccoli.

Low Biological Value Proteins

Conclusion

​What We learnt TOday

What We Learnt Today

  1. We were able to identify two (2) food sources high in protein needed in the human diet.

  2.  We also stated two (2) elements that make up proteins in the body.

  3.  Lastly we differentiate between high biological and low biological value protein available for human consumption.​
