Study Notes

Supplements Overview

Fresh and minimally processed foods are the best sources of vitamins and minerals.
Nearly 60% of the population uses multiple vitamin and mineral supplements.

Characteristics of Supplement Users

Individuals likely to need supplements include:
- Those on restricted diets
- Pregnant women
- Individuals experiencing appetite loss due to illness or surgery
- People with severe food allergies
- Those with depleted immune systems

Categories of Vitamin and Mineral Supplements

- Contains daily dosages that do not exceed daily values (DVs).

Regulations and Market Dynamics

The FDA regulates vitamin-mineral supplements but has limited authority.
The Dietary Supplement Health and Education Act (DSHEA) of 1994 allows manufacturers to introduce supplements without pre-market approval.
Since DSHEA, dietary supplements have surged in number—growing nearly 20 times since 1994.

Food-First Approach

A food-first strategy is recommended for obtaining vitamins and minerals.
Foods provide complex carbohydrates, fiber, protein, unsaturated fats, and antioxidants.
Example daily menu includes nutritious meals like cereal with low-fat milk, tuna sandwiches, and roasted almonds.

Nutritional Content of Common Foods

A small carrot provides 6000 IU of Vitamin A (100% DV).
An ounce of almonds contains over 7 mg of Vitamin E (50% DV).
A medium orange has 70 mg of Vitamin C (78% DV).

Health Claims on Supplement Labels

Manufacturers may claim:
- Health: Links between ingredients and reduced disease risk.
- Nutrient: Information on relative nutrient amounts.
- Structure/Function: Effects on body systems without mentioning diseases.

Recommended Dietary Allowances (RDAs)

RDAs are updated every 5–10 years and serve as goals for healthy individuals.
Specific RDA examples for iron intake:
- Adolescent females: 15 mg
- Adult females: 18 mg
- Adolescent males: 11 mg
- Adult males: 8 mg

Market Segmentation of Supplements

Supplements tailored to different demographics:
- Children's vitamins feature catchy packaging and flavors.
- Prenatal vitamins use pastel coloring, while seniors’ vitamins come in silver packaging.

Scientific Perspective on Supplements

Little scientific backing supports the need for vitamin-mineral supplements in the absence of deficiency.
Foods are typically more bioavailable than supplements.
Supplements may be essential in certain circumstances, but a food-first approach is emphasized.

Dietary Guidelines and Nutritional Insights

RDAs were initially developed during World War II for nutritional guidance.
The Dietary Guidelines, updated every five years, emphasize the importance of nutrient-dense food choices.
The 2020–2025 Dietary Guidelines promote the concept of “Make Every Bite Count,” encouraging healthy dietary patterns throughout all life stages.
