    Understanding how food works is an essential first step to a healthier life.

    We don’t need to understand how everything works in order to enjoy it. You can enjoy the photos on Instagram without knowing how the app functions. But food is different. Eating without understanding is a surefire recipe for a bigger waistline, more trips to the doctor and an early death. So it’s important to understand at least the basics – the macronutrients that we need in large quantities.

    First up are carbohydrates, sugar molecules that our body breaks down into glucose. Once it hits the bloodstream, glucose provides energy to the body, so we definitely need carbohydrates in our diet. But it’s far better to get this energy from complex carbohydrates like whole grains and fiber than from simple carbohydrates like white flour or refined sugar.

    Complex carbohydrates release glucose into the blood slowly, giving us sustained energy. Simple carbohydrates such as a sugary treat or white bread act quickly, providing an instant energy boost. But they are also linked to all sorts of problems, from diabetes and weight gain to impotence.

    Proteins are another source of energy, but their real purpose is to serve as building blocks. Made up of amino acids, they can combine together into structures that the cells in our body need to run properly. Everything from celery to ground beef contains protein, but proteins in animal cells contain different amino acids than those in plant cells. That’s why, if you are a vegetarian, you should strive to maintain a diverse vegetarian diet to get the full variety of amino acids that your body needs.

    The next key macronutrient is fat. Like carbohydrates, it’s a source of energy. But fat contains a lot more energy than carbohydrates; 2.25 times more, in fact. Fat is an essential component of our diets, but it’s important to know that you should concentrate on good fats – unsaturated fats from olives, avocados and nuts or fats like the omega-3 oil found in salmon

    In contrast, you should avoid saturated fats that are typically found in animal products such as cheese and butter. There’s considerable evidence that swapping out saturated for unsaturated fats in your diet reduces inflammation, risk of cancer and heart disease and even cognitive decline.
