DLM: Bubka and Bryan are right IMHO. You've got to produce some specific studies showing oil and diet are direct causes of male pattern baldness.
I haven't seen any. I do agree that bad diet can only hurt our ailment but cause it.......hmmm?
Btw, the pre-war Japanese people I knew ate alot of white rice. Aren't there alot of carbs. in white rice?
there is also fat and protein in rice so the macronutrient ratio is better plus they ate a lot of good fats in fish. plus baldness DID exist in the pre-war japs (altho rare) but anyways the second of these articles is based on these studies:
