Explanation
Dietary fats are one of the three major components or macro-nutrients of all foods. The other two are carbohydrates and proteins. During digestion, dietary fats are broken down and their constituents, glycerol and fatty acids, are released. Fatty acids have many important functions in the body.
Dietary fat is a source of energy for your body. The glycerol you get along with dietary fatty acids can be converted directly into glucose by the liver. The fatty acids, however, have to go through a series of transformations before they are turned into glucose.
Here are 10 high-fat foods that are actually incredibly healthy and nutritious.
Avocado, nuts, cheese, oil, ghee, fish, milk, dark chocolates, whole egg and full fat yoghurt.

Cattle fed with spoilt hay of sweet clover which contains dicumarol ..........................

  1. Are healthier due to a good diet

  2. Catch infections easily

  3. May suffer vitamin K deficiency and prolonged bleeding

  4. May suffer from Beri-Beri due to deficiency of B vitamins
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sweet clover poisoning is caused when feeding moldy sweet-clover hay or silage that contains dicoumarol. Dicoumarol is a toxic compound that is produced through weathering of a normal component of sweet clover called coumarol. It is the dicoumarol that causes the sweet clover poisoning, preventing normal blood clotting and causing extensive hemorrhaging. When sweet clover becomes spoiled or is improperly cured the coumarol is converted to the toxic substance dicoumarol. This toxin interferes with the metabolism and synthesis of vitamin K. 

Vitamin K is essential for liver function, necessary to prevent the seepage of blood from the circulatory system and to establish blood clotting. Without vitamin K, the blood will not clot properly after an injury, and this is why sweet clover poisoning is also called sweet clover bleeding disease.

Which one of the following is the richest source of vegetarian protein?

  1. Gram

  2. Soybean

  3. Wheat

  4. Rice
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The soybean or Glycine max is a species of legume widely grown for its edible bean. The plant is classed as an oilseed rather than a pulse by the UN food and agricultural organization. Soybeans are considered by many agencies to be a source of complete protein. A complete protein is one that contains significant amounts of all the essential amino acids that must be provided to the human body, because of the body's inability to synthesize them. For this reason, soy is a good source of protein, amongst many others, for vegetarians and vegans or for people who want to reduce the amount of meat they eat. Thus, the correct answer is option B.
