Lol don't get rid of garlic, it's super beneficial for the digestive system
I didn't eat garlic for months and my digestive system works way better than before. It's hard not to take garlic, because it is (same as onions) mixed in nearly everywhere (sauces, ketchup, mustard, snacks, meat). Sometimes it's not even mentioned on the ingredients or just as 'herbs'. But I found a way that works for me and I'm feeling much better today.
I do not eat any factory produced foods - mainly only what I cook...maybe three to four meals a year at a restaurant. Never from a take-away. If I want a sauce, I make it myself.
More important that not eating garlic and onions, is that you stop eating factory and or restaurant made foods. I'm not saying you must go to extremes, our bodies can easily handle the rare ham, bacon, jam and so on.
Watch out for spices and herbs (and honey of course) which have been radurised. They not only have no nutrition, they can harm you.
Interesting. But it seems to be merely anecdotal evidence backed. I guess it'd be good to run some control experiments. You don't have a bunch of homozygotic siblings (identical twin / triplets etc), do you, by any chance? Surely, the health benefits could have been from a range of changes in your lifestyle, assuming you don't restrict your diet / lifestyle which would make your claim somewhat more meaningful? Congrats on your improved health, of course, all the same. Long may it last. :)
