Not providing energy
- Water
- Fiber
Dietary fiber
Dietary Fiber or roughage is the portion of plant-derived food that cannot be completely broken down by digestive enzymes.
It has two main components -
- Soluble fiber - which dissolves in water -- is readily fermented in the colon into gases and physiologically active by-products, such as short-chain fatty acids produced in the colon by gut bacteria; it is viscous, may be called prebiotic fiber, and delays gastric emptying which, in humans, can result in an extended feeling of fullness.
- Insoluble fiber - which does not dissolve in water -- is inert to digestive enzymes in the upper gastrointestinal tract and provides bulking.Some forms of insoluble fiber, such as resistant starches, can be fermented in the colon.Bulking fibers absorb water as they move through the digestive system, easing defecation.

Protein
Health Guidelines for Indians by Indian Council of Medical Research
As per ICMR an adult should consume 0.8g-1g of protein as per his body weight. For someone who is an active person, protein requirement is 1g-1.2g of their body weight. Proteins provide amino acids which are vital for almost every function of the body. Include protein rich foods such as chicken, fish, eggs, paneer, lentils, beans, nuts and seeds to fulfil your daily protein requirements.
Combining cereals with pulses in the ratio of 3:1 will improve the protein quality of your meal as per ICMR.
