To give the best support to the brain functioning one should eat 130 grams of cabs in a day. Carbs are of two types: simple and complex. Simple carbohydrates need less energy to break down and is available in fruits. Complex carbohydrates need more energy in the breaking process and can be acquired thorough grains, vegetables and starch food
Another source of energy is macronutrient known as lipids of fats.Among all the funtions of the body,fats helps to transport and in the absorption of the fat-soluble vitamins like A,D,E and K.The presence of fat in the body protect us from any type of injury and regulates the temperature of our body.This is because of the reason that the fat cells stores excess energy in the body and when all energy is used then it comes from this stored fact on the body.The lipids can be simple,compound or derived form of energy and each form represents a different structure of chemical.Fat comprises of around 20% to 30 % of the daily intake of calories with 9 calories per gram.
The most essential nutrient in our body for growth is protein.Proteins are the building blocks and help in the repair of the damaged tissues of our body.A normal fluidic balance make up of the hormones of the body,anti-bodies and enzymes is possible due to protein.This is also one of the best source of energy.Protein are also required for the growth of hair,muscles,blood,nails and bones and muscles.A 10-15% daily calories comes from the consumption of proteins and it has around 4 calories per gram.Also,the sources of proteins are so many even for vegetarians.
