Eating for everyday wellness

Sure, you know you're supposed to eat well to live a long and healthy life, but what do we really know about how the foods you eat affect how you feel right now? Can red wine give you a headache, do sweets make you and the children spin out of control and will pizza really make your face break out?

Yes and no. Experts say that when it comes to eating for everyday wellness, sometimes the myths about how some foods affect health may be more powerful than the truth.

In fact, researchers may never be able to definitively separate the effects of the food from other factors to prove or disprove many of these common myths.

Just take sugar, for example.

"A lot of people think sugar causes hyperactivity, but it's actually the circumstances in which it's given in large doses like at a fun party, Halloween or a birthday that causes hyperactivity," says dietitian Nelda Mercer. "The hyperactivity link simply hasn't been proven."

“Oh my aching head”

Many people avoid also certain foods such as chocolate or red wine because they're afraid it's going to give them a headache.

However, headache expert Dr Seymour Diamond says several studies have unequivocally shown that there is no link between food and headaches. However, that doesn't mean the myth still won't hold true for some people, especially those who suffer from recurring migraine headaches.

"I've been doing this for almost 40 years, and I believe people. And people routinely tell us about certain foods triggering migraines,” Diamond tells us. "But only about 30% of migraineurs are really sensitive to anything."

Migraine Action recommends that people who experience recurring headaches keep a diary of foods eaten before migraine attacks to determine any possible food sensitivities. Foods frequently reported as headache triggers include:

• Aged cheeses
• Foods containing caffeine, such as coffee, tea, fizzy drinks and chocolate
• Anything pickled, fermented or marinated
• Processed meats containing nitrates
• Aspartame (artificial sweetener)

Diamond says alcohol can also trigger a headache, as anyone who has suffered a hangover after drinking too much can attest. That's because alcohol causes blood vessels to widen, causes dehydration and even can decrease your blood sugar, all of which can lead to a headache. In addition, certain drinks that have been aged or processed in a flask or barrel, such as red wine, may also contain certain by-products that can cause headaches.

“It'll make me break out”

What teenager hasn't been told to stay away from pizza or other greasy foods because it'll make their face break out with spots?

However, experts say the truth is that extensive scientific research has yet to find a connection between diet and acne. In other words, foods don't cause breakouts.

Dermatologist Dr Doris Day, says some studies are being done that are starting to show that there might be something to the food-acne link, but the problem is that it's a difficult link to prove.
