Study Notes
Macronutrients and Micronutrients
- Macronutrients include fats, carbohydrates, and proteins.
- Micronutrients encompass vitamins and minerals.
- Complete protein sources are meat, fish, and poultry.
- Incomplete protein examples are nuts and legumes.
Calories and Energy
- Calories measure energy intake.
- Food energy is quantified in kilocalories.
- Carbohydrates primarily serve as essential nutrients for energy.
Fats and Their Functions
- Fats help absorb fat-soluble vitamins and enhance food flavor and texture.
- Major roles of fats include energy storage.
- Monounsaturated fats are found in olive oil; polyunsaturated sources include corn, cottonseed, and soybean oils.
Saturated and Trans Fats
- Saturated fatty acids naturally occur in animal products and are solid at room temperature.
- Leading sources of saturated fat in the American diet are hamburgers, hot dogs, and whole milk.
- Trans fats raise levels of low-density lipoprotein ("bad" cholesterol) while decreasing high-density lipoprotein ("good cholesterol").
- To reduce trans fat intake, check for partially hydrogenated oils in ingredient lists.
Essential Fatty Acids
- Essential components of the diet include alpha-linolenic acid and linoleic acid.
- The role of alpha-linolenic acid includes maintaining blood pressure.
Cholesterol
- Cholesterol is a waxy substance that synthesizes vitamin D and hormones.
- Low-density lipoproteins transport cholesterol to organs and tissues, potentially depositing in artery walls when excessive.
Processing Grains
- During processing of whole grains to refined carbohydrates, the germ and bran are removed while calories are retained.
- Not all nutrients lost in refining are restored during the enrichment process.
Carbohydrates
- There are two main classifications of carbohydrates: simple (e.g., sucrose and fructose) and complex (e.g., lentils, rye, yams).
- Unrefined complex carbohydrates digest more slowly, providing sustained energy.
Dietary Recommendations
- To lower saturated fat intake, reduce consumption of cheese and red meat.
- Trans fats must be listed on nutrition labels if they total 0.5 grams or more per serving.
