Study Notes
Dietary Supplements
- The Dietary Supplement Health and Education Act of 1994 (DSHEA) allows manufacturers to classify nutrient supplements and certain herbal products as foods (not drugs).
- DSHEA defines a dietary supplement as a product (excluding tobacco) that contains a vitamin, a mineral, an herb or other plant product, an amino acid, or a dietary substance that supplements the diet by increasing total intake.
Factors That Influence Jamaicans' Health
- Lifestyle: a person's usual way of living, including dietary practices and physical activity habits.
- Risk factors for chronic diseases include:
- Poor dietary practices
- Lack of physical activity
- Drug use, particularly tobacco and alcohol use
- Genetics, family history, and age
- Environmental conditions
- Psychological factors
Healthy People 2030
- It is a report by the U.S. that sets national health objectives for the decade.
- It also contains information on key beneficial nutrients.
Nutrient Densities
- Nutrient density measures the amount of nutrients per calorie.
- Foods that are high in nutrients and low in calories are considered nutrient-dense.
Energy In Food
- Energy in food is measured in kilocalories (kcal).
- Carbohydrates provide 4 kcal per gram
- Fats provide 9 kcal per gram
- Proteins provide 4 kcal per gram
- Alcohol provides 7 kcal per gram
Energy Density
- Energy density refers to the energy value of a food in relation to its weight.
- Foods with high water content (for example, most fruits and vegetables) are generally low in energy density.
- Some foods are both nutrient-dense and energy-dense, such as nuts and nut butters.
Enjoying Eating All Foods in Moderation
- Moderation means obtaining adequate amounts of nutrients while balancing calorie intake with calorie expenditure.
- Choose nutrient-dense foods and limit serving sizes of energy-dense foods.
- Incorporate moderate-to-vigorous physical activities into your daily routine.
Range of Safe Intake
- Physiological dose: the amount of a nutrient that is within the range of safe intake and enables the body to function optimally.
- Megadose: the amount of a nutrient (e.g., vitamin or mineral) that greatly exceeds the recommended amount.
Food as the Best Source of Nutrients and Phytochemicals
- Dietary supplements should not be considered substitutes for nutrient-dense foods.
- The most natural, reliable, and economical way to ensure a healthy diet is to eat a variety of "whole" and minimally processed foods.
- Processing (including refinement) often removes nutrients and other beneficial food components.
Individualized Nutrition
- There is no "one size fits all" approach to planning a nutritionally adequate diet.
- Use food guides to individualize your diet based on your likes and dislikes, budget, and lifestyle.
- Medical nutrition therapies are special diets designed to meet the needs of people with chronic illnesses.
- Even the nutritional needs of healthy people vary during different stages of their lives.
Foods and Nutrients are Not Cure-Alls
- Nutrients do not cure ailments other than nutrient deficiencies.
- Diet is only one aspect of life that influences health.
- Functional foods are made to boost nutrient intakes, reduce the risk of disease, or manage specific health problems.
Malnutrition Includes Undernutrition as Well as Overnutrition
- Malnutrition is the state of health that occurs when the body is improperly nourished.
- Malnutrition can result from inadequate or excessive amounts of nutrients.
- Overnutrition results from long-term excesses of energy or nutrient intake, often characterized by obesity (excess energy).
Nutrition is a Dynamic Science
- As researchers continue to explore the complex relationships between diets and health, nutrition information constantly evolves.
- Dietary practices and recommendations often change as new scientific information becomes available and is reviewed and accepted by nutrition experts.
- It is important to evaluate research results published in scientific journals.
Nutrition Facts Panel
- Provides information about energy and nutrients in packaged foods.
- Indicates serving size and the number of servings in the package.
- Required to list the following:
- Total fat, saturated fat, trans fat, and cholesterol
- Sodium
- Total carbohydrate, fiber, sugars
- Protein
- Vitamin A, vitamin C, calcium, and iron
Summary
- Nutrition refers to the scientific study of nutrients and how the body uses them.
- A nutritious diet plus regular exercise may reduce your chances of developing chronic diseases.
- There are six classes of nutrients: carbohydrates, lipids (including fats), proteins, vitamins, minerals, and water.
- Nonnutritients, including phytochemicals, may be beneficial to human health.
- Macronutrients are classes of nutrients that provide energy and are needed in relatively large amounts by the body.
- Micronutrients are needed in relatively small amounts by the body, and they do not supply energy.
- Choosing a variety of foods and eating them in moderation can help ensure the nutritional adequacy of a diet.
