New research is suggesting that the less animal products in your diet, the more likely you are to be depressed. vegetarian-depression link
The evidence is not conclusive, and the article even states how Seventh-day Adventists didn’t fit that pattern, but the correlation seems to be quite strong to me.
The article also explains what I think is one of the biggest reasons for this – which is that people who think long and hard enough to make huge changes in their lifestyle, often are prone to depression anyway because of how life looks so hopeless. Frankly, if I wasn’t Christian, I would most likely be depressed myself.
This also fits in with inspired counsel that I read today, to not make diet any kind of test for salvation. It’s important, but it’s not what saves us. Only Jesus can save us. 🙂
