here are some of the craziest health and food rumors that we people believe in... find out which one are you guilty of.
1. Working out on an empty stomach burns more fat.
When you exercise, your body burns calories from both fat and carbohydrates. Recent studies show that working out on an empty stomach might burn a few more fat calories since you don’t have as many carb calories to spare, but overall calorie burn is about the same. And, based on research so far, that's what really counts when it comes to fitting into a smaller size. It does, but don't expect any fat-melting miracles
2. Does Listerine mouthwash help keep mosquitoes away?
No. Although Internet postings swear it's true, scientists beg to differ. Our research has found that people who sprayed Listerine on their arms were just as likely to be bitten as those who didn't use any repellent, says Grayson Brown, PhD, a University of Kentucky public health entomologist. The myth persists thanks to a strong placebo effect and because Listerine has eucalyptol, an ingredient found in some botanical bug sprays. But the concentration in mouthwash (less than 1%) is too low to have an impact.
3. Spicy foods boost metabolism
I wish! Your metabolic rate is determined by your gender, height, present weight/body composition, and age. These factors determine the amount of calories the body will burn to maintain the basic functions of life that occur even when we sleep—the energy used by the heart, brain, lungs, intestines, etc. Eating spicy foods cannot significantly increase metabolic rate and help you burn more calories at rest. Although your body temperature may temporarily rise and your heart may beat a bit faster after eating "hot" foods, over the long term spices will not make any changes in the rate of metabolism.
4. It’s safe to follow the 5-second rule for dropped food
It's probably not even safe to follow a 1-second rule: The transfer of bacteria from a contaminated surface to food is almost instantaneous—or, at the very least, quicker than your reflexes. In one study, Clemson University food scientist Paul Dawson, PhD, and students contaminated several surfaces (ceramic tile, wood flooring, and carpet) with salmonella. They then dropped pieces of bologna and slices of bread on the surfaces for as little as 5 seconds and as long as 60 seconds. After just 5 seconds, both food types had already picked up as many as 1,800 bacteria (more bad bugs adhered to the moisture-rich bologna than the bread); after a full minute, it was up to 10 times that amount.
