What Should You Eat To Get More Zinc In Your Daily Diet?
Your best bet is to talk to a doctor about it, word of mouth isn't always the best thing for you. If your doctor says this is o.k., he/she can tell you how much you need for acne, if indeed it does work that way. Hope this helps.
If you need zinc every day, consider lentils as a staple in your diet. They complement many main dishes, and if seasoned right will not bore you.
I was looking for info on Zinc as well, right now I take a multivitamin which provides 100% of your daily zinc but was looking for a way to eat it. I know the multi vitamin helped clear up the acne on my arms!
