A short-term low-calorie diet may help reduce gum inflammation, according to a new study. Researchers found that people who followed a fasting-style diet had lower signs of inflammation in their gums and blood. The study suggests that healthy lifestyle changes may support regular dental care. The study was published in the Journal of Clinical Periodontology (JCP).
The research was carried out by scientists at King’s College London. It is the first study to show a clear link between fasting and better gum health. Gum disease is a common problem around the world. Millions of people suffer from it. A severe type of gum disease is called periodontitis. It can damage the tissues that support teeth and may even lead to tooth loss.
Scientists have also linked gum disease to other health conditions. These include heart disease and diabetes. Because of these findings, researchers are looking at new ways to improve treatment. Dr Giuseppe Mainas, one of the researchers, said that lifestyle habits could play an important role in gum health. He explained that excellent oral hygiene is still important, but other healthy changes may also help patients.
The study involved 28 people receiving treatment in hospitals across Spain. The participants were divided into two groups. One group followed a special low-calorie diet. The other group continued eating normally. Those on the diet reduced their calorie intake for five days at a time. For the first two days, they consumed around 1,100 calories per day. For the next three days, they ate about 750 calories daily.
On the sixth day, they slowly increased their food intake with soft foods. By the seventh day, they returned to their normal eating habits. This process was repeated three times over a six-month period. Researchers said most participants found the diet easy to follow. They were able to stick to the plan without major difficulties.
At the end of the study, scientists collected samples from the participants. These included blood samples and fluid from the area between the teeth and gums. This fluid plays an important role in protecting the gums. It helps fight harmful bacteria and supports gum health. The results showed clear differences between the two groups. People who followed the fasting-style diet had lower levels of inflammation markers. Both their blood and gum tissues exhibited these improvements.
One important marker was C-reactive protein. This substance is often used to measure inflammation in the body. Lower levels usually indicate reduced inflammation. The fasting group also showed lower levels of molecules linked specifically to gum inflammation. Professor Luigi Nibali, a senior researcher involved in the study, said there could be several reasons for these benefits.
One possible reason is a reduction in oxidative stress. Oxidative stress happens when harmful molecules damage cells and tissues. It is a major cause of inflammation in the body. Fasting may help lower this damage. Another reason could be reduced consumption of unhealthy foods. Foods high in calories and refined carbohydrates, such as cakes, biscuits, and sugary snacks, can increase inflammation. Eating less of these foods may help the body stay healthier.
Researchers also believe fasting may affect the microbiome. The microbiome is the community of bacteria that lives in the body. Many of these bacteria help keep people healthy. However, scientists say more studies are needed to understand this connection fully. The researchers envision the potential use of fasting-style diets alongside standard gum disease treatments in the future. These treatments include professional dental cleaning and proper oral care at home.
The findings add to previous research from King’s College London. Earlier studies showed that following a Mediterranean-style diet can improve gum health. Researchers also found that successful treatment of gum disease may help lower the risk of conditions such as diabetes and heart disease. The new study further confirms the close connection between oral health and overall health. It also highlights how simple changes in diet may support healthier gums and a healthier body.
