Busting Food Myths with Nicole Senior

Myth: Festive overeating is harmless.
Fact: Festive overeating can have adverse health consequences. It’s time to outsmart our primitive instincts and engage higher order thinking about how much we eat during the holidays.

The holiday season is rapidly approaching and chief cooks in households around the world are starting to think about what festive fare to serve family and friends (of course the better organised ones have already made the Christmas puddings, mince pies and cakes). Serving the special foods that are part of your cultural traditions is part of the ritual and something everyone looks forward to. In my family, ensalada rusa (Spanish potato salad) will always be on the buffet table along with other traditional Spanish and Aussie Christmas fare. It's all so tempting, it's hard not to overfill your plate ...

However, is it really harmful? Well, professor of nutrition and psychiatry at Tufts University Susan Roberts reports Americans gain an average of between five and eight pounds in the short interval between Thanksgiving and the New Year (just one month). I’d bet most of that stays put after the Christmas tree is packed away.

The big problem these days with our festive fare is the the holiday season seems to have spread way beyond that special Christmas eve dinner or Christmas lunch with parties and celebrations galore, each vying for your eating affections. However each time you overload your system with excessive food, it’s akin to metabolic assault: your blood becomes milky with fat (post-prandial lipaemia); glucose, insulin levels and inflammatory hormones rise; your blood vessels become less flexible (called endothelial dysfunction) and your blood becomes more likely to clot (or pro-thrombotic). Unfortunately for those with diabetes or pre-diabetes, these adverse effects are worse.

And did you know that rather than signalling the body to ease-off at subsequent meals, huge meals actually increase appetite for the next meal perpetuating a vicious cycle of overeating (people often say their stomach has stretched). Eating high GI foods makes things worse. It’s no wonder emergency rooms experience a rush of cardiac patients on Christmas and Boxing Day.

Surely it’s time to move on? The planet can no longer sustain such excess and our physical health is suffering as a result. Here are some tips to help you resist the pull of festive overeating and holiday weight gain:

HOW to eat
Many of the adverse effects of overeating can be reversed by exercise, but it’s hard to throw a ball around when you’ve fallen into a postprandial stupor and can’t get out of your chair. Perhaps the best test of eating the right amount is having some get-up-and-go a few hours after getting up from the table? Sincere best wishes to you and yours for a happy and healthy festive season.
