Omega Fat Ratio Linked to Depression and Heart Disease

A recent study buttresses one explanation for the rise of depression and heart disease in recent generations: an increase in processed vegetable oil in the diet. Doctors at Ohio State University measured blood ratios of omega-3 to omega-6 fatty acids and found….

The more omega-6 fatty acids people had in their blood
compared with omega-3 fatty acid levels, the more likely they were to
suffer from symptoms of depression and have higher blood levels of
inflammation-promoting compounds…. The 6 individuals diagnosed with
major depression had nearly 18 times as much omega-6 as omega-3 in
their blood, compared with about 13 times as much for subjects who
didn’t meet the criteria for major depression.

That’s a striking correlation.

Omega-3 fatty acids are found in foods such as fish, flax seed oil and walnuts, while omega-6 fatty acids are found in refined vegetable oils used to make everything from margarine to baked goods and snack foods. The amount of omega-6 fatty acids in the Western diet increased sharply once refined vegetable oils became part of the average diet in the early 20th century.

According to the Vegetarian Society of the United Kingdom, a reliable source of omega-3 is ground flax seed. Tofu, apparently, is only so-so.

A BETTER WAY TO DO THIS?

We have an ambitious $350,000 online fundraising goal this month and we can't afford to come up short. But when a reader recently asked how being a nonprofit makes Mother Jones different from other news organizations, we realized we needed to lay this out better: Because "in absolutely every way" is essentially the answer.

So we tried to explain why your year-end donations are so essential, and we'd like your help refining our pitch about what make Mother Jones valuable and worth reading to you.

We'd also like your support of our journalism with a year-end donation if you can right now—all online gifts will be doubled until we hit our $350,000 goal thanks to an incredibly generous donor's matching gift pledge.
