LONGECITY

I've heard a lot of conflicting ideas about whether or not Poly Unsaturated Fat's are good for you. 

Omega 3's are good for telomeres and skin, but they have PUFA's. Some say to use more mono-unsaturated fats than Poly.. What do you believe these days. 

I'd like to hear your opinions and conclusions you have drawn from the research you took the time to do whether or not PUFA's are good or bad. Please site your sources. 

Also I heard that Olive oil increases Adipose tissue which is generally a good thing, i'll try to post some studies on this later as I find them. 

PUFAs are good or bad considering the context. They are actually essential, you must have them for health and survival. And the following is just my opinion based on my research... And I am not going to cite these claims because it is too tedious to do, but I guarantee the science is there:

The endogenous fats in the human body is saturated-fat (SF) and monounsaturated-fat (MF). These are the primary fats found in milk and also are the fats we can make ourselves from carbohydrates and it seems to be that the body prefers to have mostly these fats as the main types of fat stored in the body. PUFAs are suppose to make up a small percentage of total body-fat or in other words the body prefers to have a high ratio of both SF & MF to PUFA.

Their are two types of PUFAs. One is the omega-6 and the other is the omega-3. The balance should be 1:1 or no greater than 5:1, but currently the ratio of omega-6 to omega-3 is 20:1. This imbalance causes some very serious issues and underlines most chronic diseases. Efforts should be taken to lower the consumption of omega-6 in order to balance out the ratio between the two.

What many people do and what the mainstream suggests, is to take large amounts of fish-oil and flaxseed-oil to bring the ratio back into better balance, but that is not correct for two main reasons. The first is that taking in large amounts of fish and flaxseed oils causes more lipid-peroxidation and depletes vitamin-E. The second is that it lowers the SF & MF to PUFA ratio, which has serious problems as well, mainly diabetes and hormonal imbalances.

The solution is to lower consumption of foods high in omega-6 and supplement slowly with omega-3s to try and restore balance.
