YOU IN? DIGESTING FOOD
Here’s the basic information on how food works for you:
Cells are the building blocks of every single living organism on earth, including us. They’re tiny little structures so small, you need a microscope to look at them. The total content of a cell is called protoplasm. It is surrounded by a thin membrane.

We have millions of living cells within us, and every one of them needs a very precise form of energy in order to function.
The energy is provided by carbohydrates (carbs), proteins, and fats in the food we eat and drink. During digestion, the structure of proteins, fats, and carbs is broken down, down, down into very tiny usable pieces, which are carried through our blood to cells.
Each cell is like an incredibly complex little factory that has a specific job to complete for the good of our whole body.
THE MACROS (AKA MACRONUTRIENTS)
Proteins, carbohydrates, and fats are called macronutrients (big nutrients). We need lots of these. They’re our only source of energy.
Foods contain a variety of different nutrients. Some foods are famous for their high protein content (tofu, fish, chicken, and lentils, for example), others are famous for their high carb content (whole grains, including cereals and rice), and others are famous for their fat content (olive oil and nuts).
