HUMAN NUTRITION

Detailed explanation-1: -Carbohydrate digestion begins in the mouth where salivary amylase starts the breakdown. After breaking down throughout the digestive system, monosaccharides are absorbed into the bloodstream. As carbohydrates are consumed, the blood sugar levels increase, stimulating the pancreas to secrete insulin.

Detailed explanation-2: -Vitamins B2 and B3 These two vitamins help break down carbohydrates into absorbable products by processing their calories. This happens before absorption to ensure that you obtain maximum energy by metabolizing them. Niacin also supports the digestive system by ensuring that almost all carbohydrates are broken down.

Detailed explanation-3: -Carbohydrates, as the body’s primary source of energy, generally pass through the digestive tract more rapidly than either protein or fats. Protein digests faster than fats.

Detailed explanation-4: -Carbohydrates are the quickest, and fats are the slowest. Carbohydrates, proteins, and fats are digested in the intestine, where they are broken down into their basic units: Carbohydrates into sugars. Proteins into amino acids.
