The macronutrients are the three main nutrients your body needs to survive. They include carbohydrates, dietary fats and protein. But what exactly do they do for your body?

Read on for six of the fantastic benefits they can provide.

1) DISEASE PROTECTION

Dietary fats can protect you from a number of diseases. They reduce your heart disease risk by lowering blood pressure, lowering blood triglyceride levels and reducing the presence of lipoprotein (a) (a strong risk factor for heart disease) in your blood. Dietary fats have also been shown to protect you from breast cancer, colon cancer and prostate cancer. Finally, they keep your immune system strong which further enhances your ability to fight disease.

2) ENERGY

Carbohydrates provide your body with a quick, convenient source of energy. This enables all the cells in your body to function properly. Whilst your body can break down dietary fats and protein for energy it is a much less efficient process.

3) FIBRE, PHYTONUTRIENTS AND VITAMINS

Carbohydrates provide your body with a number of important nutrients. Fibre is an indigestible carbohydrate that keeps your blood glucose levels stable and promotes good bowel health. Phytonutrients are naturally occurring chemicals found in plants that protect your body from damage and disease. Vitamins are essential nutrients that protect you from disease, keep your immune system strong, support healthy growth and much more.

4) HEALTHY CELLS

The primary function of protein is to build, maintain and repair your body’s cells. When you are growing your body uses protein to build strong bones, muscles and more. When you are fully grown your body uses protein to keep these cells strong and repair any that become damaged. Dietary fats also support your cells by assisting in the production of healthy skin cells and keeping the cell walls strong.

5) HEALTHY ORGANS

Dietary fats play a key role in organ health. They keep your brain healthy by promoting the production of cell membranes and signal pathways. They also support heart health by providing palmitic acid and stearic acid (two types of saturated fat that the heart uses for fuel when stressed). On top of this they protect your liver from harmful substances and have been shown to reverse liver damage. Finally, they reduce surface tension in the lungs by supporting the production of lung surfactant.

6) WEIGHT LOSS

Research suggests that dietary fats can both burn and prevent the build up of body fat. Protein can also help you lose weight in two ways. First, a meal high in protein can burn up to 25% more calories during digestion than a meal high in carbohydrates. Secondly, protein (and in particular the amino acid leucine) has been shown to act as an appetite suppressant.

I hope this article has given you a better insight into the macronutrients and how they benefit your health. As you can see they do almost everything your body requires. They give you energy, protect you from damage and disease, support healthy growth and even help you lose weight. So if you want to enjoy all these benefits make sure your diet contains sufficient levels of all three macronutrients.
