Nutritions Nutrients are substances in food that your body needs to grow, repair itself, and supply you with energy.
5
Calorie A unit of heat to mesuare the energy your body uses and the energy it receives from food
6
Nutrients that provide Energy Carbohydrates Proteins Fats Carbohydrates Proteins Fats
7
Carbohydrates Main source of energy 45 to 65% per day Simple = sugar – fructosa, lactosa (fruits, milk) Complex = starches – long chains of sugars linked togetger (pasta, bread, potatoes…) Fiber = complex can not be digested by the body (whole grain, seeds, nuts, legumes), (26. 35 g per day) Main source of energy 45 to 65% per day Simple = sugar – fructosa, lactosa (fruits, milk) Complex = starches – long chains of sugars linked togetger (pasta, bread, potatoes…) Fiber = complex can not be digested by the body (whole grain, seeds, nuts, legumes), (26. 35 g per day)

Proteins Nutrients the body uses to build and maintain it’s cells and tissues Made up of chemical called amino acids Body uses 20 amino acids 9 amino acids are essential, must get them from food.

Proteins Animal resourses: meat, eggs, dairy products Plants resourses: soya, graints, nuts, seeds, legumes Important specially for teens (bones, muscles, ligaments, hormones, enzyme…) Boys: 52 grams, girls 46 grams per day Animal resourses: meat, eggs, dairy products Plants resourses: soya, graints, nuts, seeds, legumes Important specially for teens (bones, muscles, ligaments, hormones, enzyme…) Boys: 52 grams, girls 46 grams per day

Fats Body needs fat to survive Unsaturated fats Vegetable oils, nuts, seeds Saturated fats Animal based foods, dairy, palm oil, coconut oil, Trans fat Formed by hydrogenation process, Worst type of fat! Margarine, snack foods, baked goods – cookies, crackers Recomandation – less that 25% fat´s energy per day Body needs fat to survive Unsaturated fats Vegetable oils, nuts, seeds Saturated fats Animal based foods, dairy, palm oil, coconut oil, Trans fat Formed by hydrogenation process, Worst type of fat!

Cholesterol waxy fat-like substance in your blood HDL – „Good“ Create cell wals, hormones and vit D X LDL, reduce heart attack, stroke, reducing trans fats LDL – „Bad“ Can clogs arteries Couse hard attack waxy fat-like substance in your blood HDL – „Good“ Create cell wals, hormones and vit D X LDL, reduce heart attack, stroke, reducing trans fats LDL – „Bad“ Can clogs arteries Couse hard attack
