Nutrients
Provide energy, provide structure and regulate body processes
Essential nutrients
Our bodies cannot make them so it is essential that we consume them
High nutrient density foods
Contain more nutrients per calorie
Low nutrient density foods
contain fewer nutrients per calorie
Fortified foods
Nutrients added to foods.
Dietary supplements
Supplement the diet
Organic vs inorganic
Organic = Carbon structure, vitamins, carbs, protein, lipids Inorganic = water (H20), doesn't contain carbon, minerals
Carbohydrates
Carbon, hydrogen, oxygen
4kcal energy per gram
Simple and complex carbs
(sugar, starch, fibre)
Proteins
Carbon, hydrogen, oxygen and nitrogen
4kcal energy per gram
Composed of amino acids
bone and muscle health
Lipids
Carbon, hydrogen and oxygen
9kcal per gram
Saturated: animal fats
Unsaturated: plant oils
Energy for lower intensity and longer duration activities
(saturated, mono-saturated, polysaturated omega 3 and 6)
Vitamins
Enable chemical reactions ADEK = fat soluble BsC = water soluble (vitamin c and d, niacin) (Regulation of energy production, maintenance of vision, blood clotting, etc.)
Minerals
The nervous system, cells, water balance, skeletal system
(Iron, magnesium, calcium, zinc)
16+ essential minerals
Water
Hydrogen and oxygen (h2o)
Purpose = nutrient and waste transportation, solvent, lubricant
Phytochemicals
Present in foods from plants
Non-nutrient subs in foods that are beneficial to the human body and may have health-promoting factors
Zoochemicals
Present in foods from animals
Functional foods
Way to provide health benefits beyond basic nutrition
Ex) blueberries reduce risk of disease and cancer
Designer foods
Other functional foods are designer foods or nutraceuticals
Ex) vitamins added to water. Orange juice with added calcium
