Anything that helps keep your immune system strong is a plus. Fermented foods that aid your intestinal tract, vitamin D, exercise, ect all help your immune system. Strengthening your immune system has no downside.
Sadly our Healthcare system is ran by morons who care more about making money by focusing on symptoms of disease instead of causes, like lifestyle choices, diet, ect.
Granted there are real diseases that plague us, but prevention deserves more focus. Mercola and those like him aren’t scam artist as prevention if the wise course. The problem is that we are seeing polarization on every view these days. Eating well and prevention is a must, but sometimes you need a Doctor who can operate and prescribe a medication or antibiotics, ect. Balance is the key and every individual is different.
I just had a check-up after not seeing a Dr. for over a decade, I never get a flu shot, haven’t had a vaccine of any kind since preparing for Kindergarten over 40 years ago. There’s absolutely nothing wrong me and I look 36. I eat no fast food, eat fermented foods, steak, veggies, eggs. I always have my morning coffee, smoke my pipe sometimes, drink plenty of alcohol, ect. Maybe I’m just lucky??
