Answer 1.

FUNCTION OF CARBOHYDRATES IN OUR BODY:

1. It provides energy to our body.
2. Excess carbohydrate in our body in the form of glucose, stores in liver in the form of glycogen. This polymeric reaction is catalysed by the insulin hormone.
3. They help in sparing the use of proteins for energy.
4. They also act as biological receptors in many cells of the human body.
5. In times of fasting, glucagon hormone catalyses the conversion of glycogen to glucose. That provides energy to our body.

FUNCTION OF PROTEINS IN OUR BODY:

1. They act as building blocks of our body.
2. They form an integral part of the plasma membrane.
3. Antibodies are proteineous in nature which help in providing the immunity.
4. Most of the hormones are proteineous in nature. Hormones are the chemical messengers, each hormone has got a specific action in our body.
5. They also help in providing energy to our body.

FUNCTION OF FATS IN OUR BODY:

1. They also form an integral part of the plasma membrane. As plasma membrane is composed of lipids and proteins.
2. They act as insulators for our body.
3. Adipose tissue in our body is composed of fats, they provide cushion to our body organs and help in protecting them from mechanical injury.
4. They provide good energy as like proteins. 1 gram of fat on oxidation provides 9KCal of energy.
5. Low density lipoproteins or LDL form the bad cholesterol that causes atherosclerosis. High density lipoproteins or HDL forms the good fat for our body.

Answer 2. In times like today it is tough for the people to go with the Paleo diet. Because we are more dependent upon the dairy products, cereals, junk food, refined sugar etc and there is a strict no for such foods in paleo diet. This diet is similar to what primitive man used to eat in paleolithic times.

This diet is good for us because the nutritional approach of this diet is far high in comparison to today's diet. Because today food is toxicated by the use of chemicals. Diseases like cancer, heart diseases, various auto immune diseases are common these days because of our diet. Paleo diet people rarely had these type of ailments, thus, it is good to follow it.

Answer 4. Complete proteins contain all the essential amino acids that are required by our body. They are present in meat, fish, dairy products and poultry.

Incomplete proteins do not contain all the essential amino acids. Example of it are, wheat, nuts, rice and beans.
