Scientists told about the dangers of dentures MOSCOW, 11 Dec — RIA Novosti. The use of dentures a person faces malnutrition. To such conclusion scientists from king’s College London, a study published in the journal Geriatrics & Gerontology International. Dentures prevent to chew on healthy foods — such as meat, nuts, fibrous fruits and vegetables. The same problems arise in those who once lost teeth, but dentures are out. As the researchers note, in both cases due to malnutrition weakened muscles, bones and joints, prone to injuries and fractures. “Today, almost all combat trauma is tied to the diet and the development of people’s professional approach to nutrition, and the effect on teeth problems in old age is denied,” said one of the authors of scientific works, Dr. Wael Sabbah. The study involved more than 1800 people, the average age of participants was 62 years. They were split into groups
