Effects of nutrition trends on your teeth

There are now numerous diet trends aimed at reducing weight or simply leading to a healthier lifestyle. It is also well known that your food intake has a major influence on your dental health. That's why we've looked at some of the most popular diet trends and their impact on your teeth.


Ketogenic diet

A ketogenic diet is characterised by a diet low in carbohydrates and sugar, but very high in fat. This allows the body to return to the natural state of ketosis and enables it to survive on a low food intake. If this diet is successful, the body burns fat instead of carbohydrates. This releases strong smelling chemicals called ketones. This is why your breath may start to smell like nail polish remover. To prevent this, make sure that you maintain extensive oral hygiene by brushing your teeth thoroughly, using mouthwash and flossing the spaces between your teeth. A positive side effect of a ketogenic diet is that a diet low in carbohydrates and sugar reduces the risk of tooth decay. This is because the bacteria that cause caries are deprived of their favourite breeding ground: sugar.


There are many different forms of fasting. For example, core fasting that reduces the calorie intake to a minimum over several days. With intermittent fasting, on the other hand, your food intake is concentrated on 8 hours a day, the remaining 16 hours are fasted and not eaten. Studies have shown that reduced eating and snacking also reduces the risk of tooth decay. Fasting can also improve and regulate your oral health in the long term. However, with intermittent fasting it is important that you pay attention to what you eat during the "eating hours" so that there is a positive effect on your teeth.

Low fat and vegan nutrition

A low-fat and vegan diet is very common nowadays. However, it is important that your body gets a good balance of the nutrients it needs. If you avoid dairy products, you should also make sure that you take vitamins A, D and K, as your body needs them to absorb calcium and keep your teeth healthy. If you follow a balanced diet with appropriate supplements and substitutes, a vegan lifestyle is a sustainable way of eating that does not affect your oral health. Herbal foods are also more alkaline, which helps to maintain the pH level in your mouth and has a positive effect on your teeth.

The coffee diet

The coffee diet promises weight loss if you drink a cup of black, hot coffee immediately after a meal. You should drink at least 720 millilitres a day, but you should avoid milk, cream and sugar in your coffee to avoid unnecessary calories. It is also advisable to use coffee with a light roast, as it contains more antioxidants and increases the health-promoting effect. Drinking coffee alone is not enough, of course. A balanced and calorie-reduced diet is also important to ensure that success is visible. As promising as the coffee diet might sound, it can be harmful to your teeth. The dark pigments of coffee get caught in the fine grooves on the surface of your teeth and can lead to discolouration. Coffee also contains acids that can change the pH value in your mouth and attack the tooth enamel. If the coffee diet still convinces you, make sure you drink plenty of water to protect your teeth from the acid and to stay hydrated. Also, brush your teeth thoroughly 30 minutes after drinking coffee, and ensure that you maintain good oral hygiene.
