Types of Nutrition
There are six main categories of nutrition, organized by their primary source of energy and nutrients: Macronutrient-based nutrition, Micronutrient-based nutrition, Plant-based nutrition, Animal-based nutrition, Supplement-based nutrition, and Functional nutrition.
Main Categories
- Macronutrient-based nutrition focuses on the three main energy-providing nutrients: carbohydrates, proteins, and fats, with a concrete example being the Atkins diet, which restricts carbohydrate intake to induce weight loss.
- Micronutrient-based nutrition emphasizes the importance of vitamins and minerals, such as the DASH diet, which is rich in fruits, vegetables, and whole grains to help manage blood pressure.
- Plant-based nutrition centers around plant-derived foods, including the Ornish diet, which is a lacto-ovo-vegetarian diet that has been shown to reverse heart disease.
- Animal-based nutrition relies on animal products as primary sources of nutrition, with the Paleo diet being a notable example, which excludes grains, dairy, and processed foods.
- Supplement-based nutrition involves the use of dietary supplements to fill nutritional gaps, such as Ensure, a brand of nutritional supplements designed for older adults or those with specific dietary needs.
- Functional nutrition focuses on using food to address specific health issues, such as the FODMAP diet, which is used to manage irritable bowel syndrome.
Comparison Table
| Category | Primary Source | Cost | Speed of Results |
|---|---|---|---|
| Macronutrient-based nutrition | Carbohydrates, proteins, fats | Moderate | Variable |
| Micronutrient-based nutrition | Fruits, vegetables, whole grains | Low-Moderate | Long-term |
| Plant-based nutrition | Plant-derived foods | Low-Moderate | Variable |
| Animal-based nutrition | Animal products | High | Rapid |
| Supplement-based nutrition | Dietary supplements | High | Rapid |
| Functional nutrition | Specific foods for health issues | Moderate-High | Variable |
How They Relate
The categories of nutrition often overlap, with Macronutrient-based nutrition and Micronutrient-based nutrition being closely related, as a diet that is balanced in terms of macronutrients is also likely to provide adequate micronutrients. Plant-based nutrition and Animal-based nutrition are distinct but can be combined in a Flexitarian diet, which is primarily plant-based but includes occasional consumption of animal products. Supplement-based nutrition can be used in conjunction with any of the other categories to fill nutritional gaps, while Functional nutrition can involve elements of all the other categories, as it uses specific foods to address health issues. For example, the Ornish diet, which is a type of Plant-based nutrition, also incorporates elements of Functional nutrition by using diet to reverse heart disease.
