Macronutrients

Carbohydrates are important to give our body energy. There are three types of Carbohydrates:

• Monosaccharides: These are the worst ones and they are often in fast food, white flour products, or candies, which you can try to avoid (with exceptions of course)
• Disaccharide: This type can be found in milk products and some fruits 
• Polysaccharide: This is the best type of Carbohydrate. They are usually in rice, sweet potatoes, etc. You can get your energy from these products.

The opinion on proteins diverges a lot among experts. There are the ones that say that you need 0.5 or 1g protein per kg and others say it has to be 2g protein per kg. There was a time when I was obsessed with proteins and even counted them (also because I try to avoid meat and animal products and that makes it a little harder to get your proteins). I think if you pressure yourself like that the result won’t be good. So now I am more relaxed. I try to eat protein on all 3 meals, but I don’t count the proteins anymore.

Sources of protein: meat, nuts, oat, eggs and milk products, peanut butter, legumes

Many people try to avoid fat as much as possible and think this is very healthy. That’s only partially true. It depends on the type of fat you eat and on the amount. Some fat, like the unsaturated ones (mono and poly) are super important for our health and should therefore be consumed.
 
There are four types of fats in food:

• trans fat: These are the worst ones. They can be found in fast food. Try to avoid as much as possible (of course you can make exceptions sometimes)
• saturated fat: Saturated fat isn’t very good and can be found in animal products. You can eat it without problems, but maybe decrease the amount a little.
• mono-unsaturated fat: Unsaturated fat is considered "good" fat. You can find it in avocados or olive oil.
• poly-unsaturated fat: This is the best one which can be found in nuts and seeds as already mentioned.
