I must say myths are quite delicious, backed with delightful stories, passed on from one friend to another, easy to spread and enjoy because the truth can be, well, actually boring. Here are some common myths and the...."boring" truth:
1. The main reason to brush your teeth is to remove food debris.
False. Brushing is a great way to get the gunk out of your teeth after a meal. But the real benefit of brushing is to eliminate the bacteria that cause cavities and gum disease. Bacterial plaque constantly forms on teeth and gums and is one of the main causes of tooth decay and gum disease. Since plaque-building bacteria thrive on foods that contain sugars and starches, you need to brush your teeth twice a day for at least two minutes each time and floss once a day. If calcified plaque, known as tartar, starts to get under your gum line, it's time to head to the dentist for a professional cleaning, usually every six to nine months.
2.Once you've had a caesarean section, you'll always have to have one.
Not so. Fifty to 80 per cent of women who deliver by C-section because their labour failed to progress (known as dystocia) or their babies were in a breech position can successfully have vaginal deliveries for the next baby. This is known as vaginal birth after caesarean. There are, however, some circumstances under which a woman would always have to have another C-section; these include a vertical incision for the original C-section or extensive uterine surgery. Both can increase the risk of uterine rupture during a subsequent labour and delivery.
3. Cracking your knuckles will cause arthritis or big knuckles.
Cracking your knuckles occasionally may annoy those around you and make your joints sore, but there's no evidence that this directly causes arthritis, a disorder characterized by sore and swollen joints. If you crack your knuckles all the time, however, you could injure the cartilage and cause the joints to swell. Keep this up and eventually it may lead to degenerative joint disease, such as arthritis.
4. If you drop food on the floor and pick it up within five seconds, it's safe to eat.
The "five-second rule," or other timed variations, doesn't prevent bacteria and other germs from getting on fallen food. If you can't wash the food that has fallen on the floor, don't eat it. Sometimes adults, often jokingly, say this myth in front of children. It's important to teach children that the "five-second rule" isn't true and that they shouldn't eat food that has fallen on the floor.
5. Microwaving food destroys the nutrients -False
According to Harvard Publications, "Some nutrients break down when they’re exposed to heat, whether it is from a microwave or a regular oven. Vitamin C is perhaps the clearest example. But because microwave cooking times are shorter, cooking with a microwave does a better job of preserving vitamin C and other nutrients that break down when heated."
6. Washing your vagina with soaps, feminine washes and scented creams helps keep it fresh and clean.
False. The vagina (not to be confused with the vulva) is capable of cleaning itself. Douching with chemicals that are supposed to make your vagina smell like a field of flowers actually ends up having quite the opposite effect. They wash out all the healthy bacteria that helps your vagina stay clean and infection-free. The chemicals left behind by douches can cause irritation and even burning, and the same goes for feminine sprays. Using just warm water and your fingers is sufficient in cleaning the vagina.
7. Deodorants can cause breast cancer.
False. Researchers at the National Cancer Institute (NCI), a part of the National Institutes of Health, are not aware of any conclusive evidence linking the use of underarm antiperspirants or deodorants and the subsequent development of breast cancer. The U.S. Food and Drug Administration (FDA), which regulates food, cosmetics, medicines, and medical devices, also does not have any evidence or research data that ingredients in underarm antiperspirants or deodorants cause cancer.
