Question

types of prorien and sources​

Answer 1

Answer:

Protein can be categorized into two types: complete and incomplete proteins. Proteins are made up of smaller units, called amino acids. Complete proteins contain all of the amino acids your body needs and include meat, fish, poultry, dairy, and soy products.

Answer 2

Explanation:

Protein is the basic component of living cells and is made of carbon, hydrogen, oxygen, nitrogen and one or more chains of amino acids. The three types of proteins are fibrous, globular, and membrane.

Sources of protein

Some sources of dietary protein include:

lean meat, poultry and fish

eggs

dairy products like milk, yoghurt and cheese

seeds and nuts

beans and legumes (such as lentils and chickpeas)

soy products like 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.

The Australian Dietary Guidelines recommend particular serves per day from the lean meat and poultry, fish, eggs, tofu, nuts and seeds and legumes/beans food category, including:

men aged 19-50 years = 3 serves

men aged 51 years and over = 2 ½ serves

women aged 19-50 years = 2½ serves

women aged 51 years and over = 2 serves

pregnant women = 3 ½ serves

breastfeeding women = 2 ½ serves.

A standard serving size is one of:

65 g cooked lean meats such as beef, lamb, veal, pork, goat or kangaroo (about 90-100 g raw)

80 g cooked lean poultry such as chicken or turkey (100 g raw)

100 g cooked fish fillet (about 115 g raw weight) or one small can of fish

2 large eggs

1 cup (150 g) cooked dried beans, lentils, chickpeas, split peas or canned beans (preferably with no added salt)

170 g tofu

30 g nuts, seeds, peanut or almond butter or tahini or other nut or seed paste (no added salt).

The daily recommendations for adults for foods from the milk, yoghurt, cheese and/or alternatives (mostly reduced fat) group are:

men aged 19-70 years = 2 ½ serves

menu aged 70 years and over = 3 ½ serves

women aged 19-50 years = 2 ½ serves
