I'm not a doctor and you should definitely talk to your physician about this. That said, the general medical consensus seems to be that moderation is key. Most health concerns come from extremes in either direction.

I work in healthcare and see this question frequently. The short answer is that individual results vary enormously. What works for one person might not work for another. The best approach is to work with your doctor to find what's right for your specific situation.

The evidence on this is actually mixed. Some studies show one thing, others show the opposite. When the science is unclear, I default to common sense: eat a varied diet, exercise regularly, get enough sleep, and don't stress too much about individual health fads.

Stress does more damage to your health than people give it credit for. Half the physical symptoms I used to worry about turned out to be tension and anxiety. Sometimes the best medicine is a vacation and a good night's sleep.

I asked my doctor this exact question. They said most of what you read about this is overblown and the actual risk is small for a normal healthy person. The news loves a scary health headline. Ask your own doctor before you panic.
