About 30% reduction in acne severity and pimple count is great, but it\u2019s a far cry from getting completely clear. This isn\u2019t that surprising given the limited scope of this study.<\/p>\n<ul>\n<li>The study period was 10 weeks. The researchers noted, and I agree, that had the study been longer the results would have gotten even better.<\/li>\n<li>The study focused on glycemic index as a factor but ignored other dietary factors, such as dairy, allergic effect of foods, etc.<\/li>\n<li>The low GI treatment diet still included lot of grains and other potentially problematic foods.<\/li>\n<li>Diet is just a part of the solution. Acne is also affected by stress, gut health, sleep patterns and external skin care. So you can\u2019t really expect to get perfect results with diet alone.<\/li>\n<\/ul>\n<p>In conclusion, nothing that new here. This study just adds to the evidence that diet does affect acne. And that you should treat acne with both internal (diet and lifestyle) and external means.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Into my Google Reader account popped this Korean acne-diet study.
