Protein
Protein provides the building blocks of the body, and not just for muscle. Every cell, from bone to skin to hair, contains protein.
Proteins are made of up different amino acids. While the body can create some amino acids on its own, there are many essential amino acids that can only come from food. You need a variety of amino acids for your body to function properly.
Carbohydrates
Carbohydrates are necessary for a healthy body. Carbs fuel your body, especially your central nervous system, and brain, and protect against disease, according to the Mayo Clinic.
Carbohydrates should make up 45 to 65 percent of your total daily calories, according to the Dietary Guidelines for AmericansTrusted Source
Fats
Fats often get a bad rap, but recent research has shown that healthy fats are an important part of a healthy diet.
According to Harvard Medical School, fat supports many of your body’s functions such as vitamin and mineral absorption, blood clotting, building cells, and muscle movement.
Including healthy fats in your diet can help you to balance your blood sugar, decrease your risk of heart disease and type 2 diabetes, and improve your brain function. They’re also powerful anti-inflammatories, and they may lower your risk of arthritis, cancer, and Alzheimer’s disease
Vitamins
Vitamins are vital for warding off disease and staying healthy. The body needs these micronutrients to support its functions. There are 13 essential vitamins that the body needs to function properly, including vitamins A, C, B6, and D.
Each vitamin plays an important role in the body, and not getting enough of them can cause health problems and disease.
Vitamins may lower the risk of lung and prostate cancer, and they’re powerful antioxidants. Vitamins like vitamin C boost the immune system and help the body heal.
water
You can go for weeks without food, but you can’t last more than a few days without water. Water is absolutely crucial for every system in your body. It’s also the main thing you are made of. About 62 percent of your body weight is water.
Water improves your brain function and mood. It acts as a shock absorber and a lubricant in the body. It also helps flush out toxins, carry nutrients to cells, hydrate the body, and prevent constipation.
