How Nutrients Work

Nutrients from food are absorbed by the body as it passes through the digestive system:

Nutrients are essential for cell growth, maintenance and repair. Nutrients provide energy to enable your body to function efficiently. Nutrients, along with fiber and water, are essential to your good health.

Although nutrients can work alone, each depends upon the others to be the most effective. The main nutrients are the macronutrients, carbohydrates, proteins, and fats – and the micronutrients, vitamins and minerals. Milkthistle, cranberries, spinach leaves, and acerola cherries.

What Macronutrients Do

Macronutrients Are Essential for Good Health:

They assist in breaking down carbohydrates and fats, which provide energy to the body.

They assist in the absorption of protein, which provides the building blocks necessary for cell growth and repair.

What Micronutrients Do

Vitamins and minerals do not in themselves provide energy, but macronutrients depend on them to regulate the release of energy from food.

Vitamins are organic substances.

They activate enzymes, which are proteins that act as catalysts to speed up biological reactions that take place in your body.

Your body produces a certain amount of vitamins D and K, but all other vitamins come from your diet or supplementation.

Minerals are inorganic substances that originate from rocks and ores and enter the food chain through the soil.

We get minerals either by eating plants grown on mineral-rich soil or by eating animals that have fed on these plants.

Calcium, magnesium and phosphorus are the major constituents of bone.

Sodium and potassium control your body's water balance.

Other minerals (chromium, iron, and magnesium) are needed for various chemical processes to take place in the body.

Omega Fatty Acids

Natural nutrients, also referred to as phyto-chemicals, are compounds that act as a natural defense system in plants, and that also have a beneficial effect on human health.
