Good for what ails you? Junk food like burgers could make you less stressed, new research suggests (AFP)

New Australian research shows that eating junk food appears to lower stress levels.

Professor Margaret Morris from the University of New South Wales conducted research on mice who had been separated from their mothers.

Animals given junk food appeared less stressed and agitated than those fed on a healthy diet.

Professor Morris says the brain pathways regulating appetite in rats are similar to those in humans.

The research was presented at the Australian Neuroscience Society meeting in Hobart.

That is interesting. Since high levels of stress can lead to disease, could junk-food be healthier? Research has not shown any benefits to eating healthy food (whatever that is?) compared with a moderate consumption of junk food and regular excercise.

In my opinion the taste of food is more important than the health benefits.

However if I was to avoid one food for health reasons it would be organic maize as it usually has high levels of this lovely toxin:

Fumonisin B1 is the most prevalent member of a family of toxins produced by several species of Fusarium moulds which occur mainly in maize. Fumonisin B1 contamination of maize has been reported worldwide at mg/kg levels. Human exposure occurs at levels of micrograms to milligrams per day and is greatest in regions where maize products are the dietary staple.

Fumonisin B1 is hepatotoxic and nephrotoxic in all animal species tested. The earliest histological change to appear in either the liver or kidney of fumonisin-treated animals is increased apoptosis followed by regenerative cell proliferation. While the acute toxicity of fumonisin is low, it is the known cause of two diseases which occur in domestic animals with rapid onset: equine leukoencephalomalacia and porcine pulmonary oedema syndrome. Both of these diseases involve disturbed sphingolipid metabolism and cardiovascular dysfunction.

Oh and I should point out that transgenic maize usually contains1000-fold less fumonisin than organic maize.

Like my grandma said every time she started a cigarette:

"We need a reason to die, don't we?"

In Spanish:
"de algo hay que morir, no?"
