Study Notes
Importance of Minerals
- Minerals are essential for human health and can be obtained through diet from various food sources.
- There are 20 essential minerals required for a healthy diet.
Classification of Minerals
- Major minerals are required in the diet in amounts larger than 100 milligrams per day.
- Examples of major minerals include sodium, potassium, chloride, calcium, phosphorus, magnesium, and sulfur.
Food Sources of Minerals
- Major minerals can be found in various foods, including dairy, mixed dishes, desserts, and vegetables.
- Calcium, for example, is consumed in the diet in Guam through dairy, mixed dishes, desserts, and vegetables.
Bioavailability of Minerals
- Minerals have low bioavailability, meaning they are not as efficiently absorbed as vitamins.
- Plant-based foods often contain factors that inhibit mineral absorption, such as oxalate and phytate.
- Animal-based foods tend to have better mineral absorption.
- Increasing dietary intake of a particular mineral can decrease its absorption.
Interactions between Minerals and Vitamins
- Excess zinc in the diet can impair iron and copper absorption.
- Certain vitamins, such as vitamin C, can enhance mineral absorption (e.g., iron).
- Vitamin D can enhance calcium and magnesium absorption.
Factors Affecting Mineral Absorption
- Gastrointestinal disorders and diseases, such as Crohn's disease and kidney disease, can impair mineral absorption.
- The aging process can also impair mineral absorption, putting the elderly at higher risk for mineral deficiencies.
