Protein
Protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.
For this reason, you should eat high-quality protein at every meal.
Carbohydrates
Sources of carbohydrate include whole grains, fruit, and vegetables. Carbohydrates, also known as saccharides or carbs, are sugars or starches. They are a major food source and a key form of energy for most organisms. They consist of carbon, hydrogen, and oxygen atoms.
Unsaturated Fats
Overall, saturated fat has a less healthful effect on the body compared to unsaturated fat. This means unsaturated fat may be a wiser dietary choice, although there are some exceptions.
