Junk foods: link to fat and sadness?

November 4, 2009

That’s what some researchers are saying. 

Researchers at University College London say a diet high in processed and fatty foods leads to higher risk of depression.   According to a story from AFP, those who ate “whole foods” were 26 percent less likely to develop depression than those who ate mainly processed foods or foods high in fat and sugar. 

And in today’s Huffington Post, Dr. Mark Hyman talks about research that links food allergies with obesity.   He says that common food allergens, like gluten, dairy, eggs, corn, yeast,  peanuts and soy, may trigger inflammation, which leads to an insulin reaction, which leads to storing fat in the body.   But what can trigger food allergies in the first place?  You guessed it.  Here’s what Dr. Hyman writes:

High-fat diets change the bacterial flora in the gut. Toxin-producing bugs are promoted by the high-fat diet while anti-inflammatory and protective bugs die off. (And there are over 500 species of bugs in your gut all fighting for territory.)

In fact, our highly processed, high-sugar, high-fat, low-fiber diet – plus many drugs like antibiotics, steroids, anti-inflammatories, acid-blockers, and hormones – completely alters the bacterial ecosystem in the gut, leading to breakdown, inflammation, and a leaky gut…

In fact, when you eat a bad diet, bad bugs flourish. Your whole gut ecosystem is upset and the outside world “leaks” in across a damaged gut lining. The result is not just obesity, diabetes, and heart disease, but so many allergic, autoimmune, and inflammatory diseases.

The new research provides more good reasons to stay away from the leftover Halloween candy and eat a healthier, more fiber-filled diet.  


  1. This makes so much sense. I was so proud of my grocery cart yesterday – lots of fruits and vegetables. I bought white whole wheat flour for the first time. Oh, we like sweets, too, but most of those we make from scratch.

  2. Wow, Sharon, that’s great! I’ve become a fan of white whole wheat flour, too. It seems a great way for our kids to get whole wheat, too.
