News – “Can food change your mood?”

theguardian.comIn medieval times people believed that what they ate affected their mood. If they wanted erotic stimulation it would be eggs, beef, pomegranates or peacock. Feeling down? They’d reach for quince, dates and elderflowers. In the absence of valium, they used lettuce and chicory as tranquillisers. So when did we lose the idea that food can affect one of our biggest organs – the brain? While the link between food and diabetes, heart disease and obesity is well established, any association between mental health and diet is tentative by comparison. But it is gradually emerging as a serious topic of study.

The solution

Research carried out by a team led by Lina Begdache, assistant professor of health and wellness studies at Binghamton, New York, found that young adults (under 30) who ate fast food more than three times a week scored higher on levels of mental distress. Fast food is usually high in the saturated, trans- and omega-6 fatty acids that can provoke a low-grade inflammatory response in the body, which, in turn, is linked to anxiety and depression in both animal and human research. Those in her study who ate meat three times a week or less (which she classifies as low consumption) also had more mental health problems. “We were surprised by this,” says Begdache. But mood and meat are linked at a cellular level; tryptophan in meat is a precursor of serotonin, the brain’s “feelgood” chemical.

For adults over 30, the study found that eating less carbohydrate and more fruit reduced anxiety and depression. Fruits are high in antioxidants that protect the brain, but the low carbohydrate effect is a puzzle because carbohydrates promote serotonin production. The study looked at both the effects of diet on mood and vice versa. “But much of it is hypothetical,” says Begdache. “We can really only say they are linked.”

This is some interesting stuff, I’m definitely going to give this a try and keep track of the results, because lord knows after devouring a triple bacon cheeseburger I mayyyyyy not feel the best about myself…..but also no regrets.
