“Food is the primary source of survival, rather than personal satisfaction or psychological reward. So food must feed the body not the emotions! Healthy food is so rich in nutrients that will then be absorbed by our body” from Joe Hoertig-Paulus

Read the composition (nutrition facts) on the label before buying your food in your supermarket.

Each food contains macronutrients (substances with caloric intake: carbohydrates, fats and proteins) and micronutrients (nutrients in small quantities e.g. vitamins, minerals, phytochemicals, …).

All foods contain a combination of the 3 caloric macronutrients and all the whole-foods (especially vegetables) have the best content of micronutrients.

By law, food industries are required to label the exact food composition on each package for sale. Labeling is therefore crucial for knowing the food composition of the product we are buying (e.g. the percentage of fats, proteins, carbohydrates and other ingredients). They are given a lot of information in this way. Take advantage of it!

About whole-foods… Why should be whole? Aristotle already knew that by wisely combining the various ingredients it was possible to obtain added value. So eat whole-foods for more micronutrients, vary what you eat every day and avoid added sugars.

Check the food label!
