    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.
