A truly balanced diet rich in whole foods meets nutrient needs for most healthy adults without supplements. Supplements serve as insurance for deficiencies, not replacements, with evidence showing no broad benefits for disease prevention in well-nourished people.
When a Normal Diet Suffices
Whole foods provide synergistic nutrients better absorbed than pills:
-
Vitamins/minerals: Fruits, veggies, grains, proteins deliver 100% RDA.
-
Bioactives/fiber: Phytochemicals, antioxidants absent in supplements.
-
Large trials: Multivitamins/fish oil show no CVD/cancer/mortality reduction.
Exceptions Needing Supplements
Certain groups benefit:
-
Deficiencies: B12 (vegans), D (low sun), iron (women).
-
Life stages: Pregnancy (folate), elderly (absorption issues).
-
Conditions: Malabsorption, restricted diets.
-
Indian context: Protein gaps (dal-rice diets), vitamin D (indoor lifestyles).
Table: Diet vs. Supplements
| Aspect | Whole Foods | Supplements |
|---|---|---|
| Absorption | Optimal + synergies | Variable, often lower |
| Excess Risk | Self-regulates | Possible toxicity |
| Evidence | Reduces NCDs | No general benefit |
| Cost | Sustainable | Unnecessary expense |
