The answer to the question, for most people, would be “variety, of course!”.
However:
- For some people, it may be easier to stick to “always the same”, increasing the probability of success
- “Always the same” may lead to the consumption of better foods. For example, Dr. Valter Longo argues for garbanzos, black beans, vegetables, olive oil, nuts and salmon as good foods
- “Always the same” may also lead of a bit of variety. For example, vegetables may range from tomatoes to cauliflower, for example
Is there any scientific evidence arguing pro “always the same” or “variety”?
