Can a supplement replace healthy eating?
It’s a question that comes up often.
If an orange contains vitamin C, why not just take a vitamin C supplement?
If fish contains omega-3 fats, why not take fish oil instead?
The answer comes down to something called food synergy.
Whole foods provide much more than individual nutrients. They contain combinations of vitamins, minerals, fiber, water, protein, healthy fats, and other compounds that interact in complex ways.
Research continues to suggest that the health benefits associated with foods often come from the entire package rather than a single isolated nutrient.
In Episode 245 of Real World Nutrition, I discuss:
✔ Whole foods versus supplements
✔ Food synergy and the matrix effect
✔ Fish versus fish oil
✔ Green powders and produce
✔ When supplements may be appropriate
