The percentage of lactose in milk varies with species. Human milk has a high lactose content, the percentage of lactose in human milk ranges from 6.5 to 7.5%. Unprocessed cow milk has about 4.7% lactose, unprocessed goat milk has about 4.7% lactose, unprocessed buffalo milk has about 4.86% lactose. The average in cow and goat milk is less than 5% and vary according to the breed. When human babies are reared on cow or goat milk, it is customary to add lactose, sucrose, glucose, or malto-dextrin in their feed.

Cirrhosis is an abnormal liver condition in which there is irreversible scarring of the liver. People with cirrhosis may develop jaundice, itching and extreme tiredness. When liver tries to break down alcohol, the resulting chemical reaction damage its cells. This damage can lead to inflammation and scarring as the liver tries to repair itself.

Meat, eggs and pulses are good sources of proteins. Proteins are body building substances and are an important part of a balanced diet. For vegetarian people pulses can be a good source of proteins. Our country produces a variety of 'dals' and these can be consumed as protein sources.

Carbohydrates provide us energy and are the primary cellular fuel. Carbohydrates can be simple sugars or polymers like cellulose and starch. Cereal grains like rice, wheat, maize etc. are rich in carbohydrates.

Carbohydrates provide us with energy. Carbohydrates can be monosaccharides (composed of one monomer unit only like glucose, fructose etc.), disaccharide (composed of two monomer units like maltose which is made up of two units of glucose; sucrose made up of one unit of glucose and one unit of fructose) or polysaccharide (made up of multiple monomer units example starch which is composed of multiple units of glucose).

Carbohydrates can be stored in body for subsequent use. Starch is an important storage polysaccharide in plants and glycogen is an important storage polysaccharide in animals. Both starch and glycogen are homopolymers of glucose.

The food guide pyramid is a pyramid-shaped guide of healthy foods divided into sections. Each section shows the recommended intake for each food group (i.e. Protein, Fat, Carbohydrates, and Sugars). Therefore, (b) is the correct answer.

Fish flour is a source of amino acids and vitamin with very high protein content, made of fresh sea fish or unprocessed fish wastes. Due to its rich nutritional content, it is the most important material in the rations of barn animals, poultry and fish and is commonly used in the feed industry.

• Fiber is the indigestible part of plant foods that travels through the digestive system and absorbs the water along the way.
  
• It is also known as roughage.
  
• Dietary fiber contains non-starch polysaccharides such as cellulose, dextrins, inulin, lignin, beta-glucans, and waxes.
