Good oral health is essential to our everyday lives. Apart from brushing twice a day and flossing, what we eat plays a big role in keeping our teeth healthy. Australian dentist Dr Steven Lin, according to The Independent, has revealed which foods we should be consuming to do so. You may be surprised by the suggestions, with butter, salami and soft cheeses making the list. Writing on his website, Dr Lin explains that many people who brush and floss regularly still end up with regular dental cavities, whereas those who seem to take worse care never seem to have dental problems. “Teeth are living organs and require proper nutrition to regenerate and maintain healthy levels of enamel and dentin,” Dr Lin explains. “And without proper nutrition, your teeth will struggle to stay intact.” If you’re consuming enough vitamins and minerals, your teeth will naturally regenerate, staying strong and healthy. But if you’re not feeding your body with the right nutrients, the bacteria and acid in your mouth hinder this natural process, causing your teeth to break down faster than they can regenerate. “It’s not just sugar alone that causes cavities, it’s the lack of nutrients that strengthen teeth,” Dr Lin says. “Malnutrition has become prevalent with the modern Western diet.” So what should you be eating? Essentially it all comes down to four fat-soluble vitamins: A, D, K2, and E. Here are good sources of each: Vitamin A: Beef liver, fish, milk, and eggs. Vitamin D: Fatty fish, mushrooms and grass-fed dairy products (but sunshine is the best source). Vitamin K2: Soft cheeses, eggs, butter, liver and salami. Vitamin E: Spinach, broccoli and nuts. With a balanced, nutritious diet, you’ll keep your teeth in check, your body in shape and your skin glowing.
Everyone knows that alcohol impairs cognitive and motor functions.
It can also impair 'executive functions,' which include the ability to remember, pay attention, and inhibit inappropriate behaviours, are particularly sensitive to the acute effects of alcohol. But according to a new research, alcohol might impair the ability to speak a second language. On the other hand, alcohol increases self-confidence and reduces social anxiety, both of which might be expected to improve language ability when interacting with another person. The researchers tested the effects of a low dose of alcohol on participants' self-rated and observer-rated ability to converse in Dutch. Participants were 50 native German speakers who were studying at a Dutch University (Maastricht) and had recently learned to speak, read and write in Dutch. Participants were randomized to consume either a low dose of alcohol or a control beverage that contained no alcohol, before they chatted with an experimenter in Dutch for a few minutes. The exact dose of alcohol varied depending on participants' body weight, but it was equivalent to just under a pint (460ml) of 5 percent beer, for a 70kg male. The chat was audio-recorded and participants' foreign language skills were subsequently rated by two native Dutch speakers who did not know if the participant had consumed alcohol or not (observer-ratings). Participants also rated their own Dutch language skills during the conversation (self-ratings). The researchers found that participants who had consumed alcohol had significantly better observer-ratings for their Dutch language, specifically better pronunciation, compared to those who had not consumed alcohol. "Our study shows that acute alcohol consumption may have beneficial effects on the pronunciation of a foreign language in people who recently learned that language. This provides some support for the lay belief (among bilingual speakers) that a low dose of alcohol can improve their ability to speak a second language," said Dr Inge Kersbergen, from the University of Liverpool's Institute of Psychology, Health and Society. Dr Fritz Renner who was one of the researchers who conducted the study at Maastricht University, shared, "It is important to point out that participants in this study consumed a low dose of alcohol. Higher levels of alcohol consumption might not have beneficial effects on the pronunciation of a foreign language."
