Study Notes
Nutrition
Macronutrients
- Carbohydrates: provide energy, composed of sugar, starch, and fiber
- Types: simple (sugars), complex (starches, fiber)
- Protein: builds and repairs tissues, composed of amino acids
- Essential amino acids: cannot be produced by the body, must be obtained from diet
- Non-essential amino acids: can be produced by the body
- Fat: provides energy, aids in absorption of vitamins, composed of fatty acids
- Types: saturated, unsaturated, trans
Micronutrients
- Vitamins: organic compounds essential for various bodily functions
- Fat-soluble: A, D, E, K
- Water-soluble: B, C
- Minerals: inorganic compounds essential for various bodily functions
- Macrominerals: calcium, phosphorus, magnesium, potassium, sodium, chloride
- Microminerals: iron, zinc, iodine, selenium, copper, manganese
Nutrition Recommendations
- Daily intake of fruits and vegetables: 5-10 servings
- Whole grains: 50-60% of total daily carbohydrate intake
- Protein intake: 0.8-1.2 grams per kilogram of body weight
- Fat intake: 20-35% of total daily energy intake
- Saturated fat intake: <10% of total daily energy intake
- Cholesterol intake: <300 milligrams per day
Nutrition Deficiencies
- Protein-energy malnutrition: inadequate protein and energy intake
- Iron deficiency: most common nutrition deficiency worldwide
- Vitamin D deficiency: common in populations with limited sun exposure
- Iodine deficiency: can lead to goiter and cretinism
Nutrition and Health
- Malnutrition: can lead to impaired immune function, poor wound healing, and increased risk of disease
- Obesity: associated with increased risk of chronic diseases, such as diabetes and heart disease
- Nutrition and mental health: diet has been linked to depression, anxiety, and cognitive function

Micronutrients
- Vitamins are organic compounds essential for various bodily functions, with fat-soluble (A, D, E, K) and water-soluble (B, C) types
- Minerals are inorganic compounds essential for various bodily functions, with macrominerals (calcium, phosphorus, magnesium, potassium, sodium, chloride) and microminerals (iron, zinc, iodine, selenium, copper, manganese)
Nutrition Recommendations
- Aim for 5-10 daily servings of fruits and vegetables
- Consume whole grains to make up 50-60% of total daily carbohydrate intake
- Set a daily protein intake goal of 0.8-1.2 grams per kilogram of body weight
- Limit fat intake to 20-35% of total daily energy intake
- Restrict saturated fat intake
Ingredients
Types of Ingredients
- Staple ingredients are basic ingredients used frequently in cooking, including flour, sugar, rice, and pasta.
- Pantry ingredients are non-perishable items stored in a pantry, such as canned goods, spices, and oils.
- Fresh ingredients are perishable items that require refrigeration, including meat, dairy, fruits, and vegetables.
- Aromatic ingredients are herbs and spices that add flavor and aroma to dishes, such as onions, garlic, and ginger.
- Protein ingredients are ingredients high in protein, including meat, poultry, fish, eggs, and legumes.
Measurement Units
- Dry measurements are used to measure dry ingredients, including cups, teaspoons, and tablespoons.
- Liquid measurements are used to measure liquids, including cups, milliliters, and liters.
- Weight measurements are used to measure ingredients by weight, including grams and ounces.
Ingredient Functions
- Thickeners are ingredients that add thickness to liquids, including cornstarch and flour.
- Emulsifiers are ingredients that combine two or more liquids, including egg yolks and mustard.
- Leavening agents are ingredients that help baked goods rise, including baking powder and baking soda.
- Flavor enhancers are ingredients that add flavor, including salt, sugar, and spices.
