In the colder months, maintaining a healthy vitamin D content can be a challenge. But why is this nutrient so important and can we get enough out of our diet? We dove into this subject with Professor Eric De Maerteleire, bioengineer and doctor in Agriculture and Applied Biological Sciences.
The importance of vitamin D
According to Professor De Maerteleire, vitamin D is one of the most influential vitamins on our body: "It has an impact on both our innate and our adaptive immune system. It can activate and stimulate our immune system, while also helping our body produce natural antibiotics to fight viruses and bacteria."
Besides strengthening our immune system, there are other health benefits of vitamin D:
- Healthy bones: Vitamin D plays a crucial role in preventing calcium loss from the bones, reducing the risk of osteoporosis and weakened bones.
- Anti-inflammatory properties: It can help reduce inflammation in the body, which can be beneficial for the health of the heart and other organs.
- Mental health: Research suggests a link between low vitamin D levels and increased risk of depression and other mood disorders.
- Diabetes: Some studies suggest that sufficient vitamin D may reduce the risk of type 2 diabetes and improve insulin response.
- Muscle health: Vitamin D can contribute to good muscle function and reduce the risk of muscle weakness and falls in elderly people.
Vitamin D in food and supplements
According to the Belgian High Health Council, vitamin D supplements are recommended, especially in winter months and for certain groups at risk. Although vitamin D is mainly produced by exposure to sunlight, food sources such as fatty fish can provide a supplement. However, Professor De Maerteleire stresses that eating fat fish alone is not enough to meet the daily needs.
Symptoms of vitamin D deficiency
Vitamin D deficiency may not initially cause noticeable symptoms, but over time health problems may arise, such as fatigue, muscle and bone pain, depression, more frequent infections and hair loss.
Risk groups
Some groups are more at risk of vitamin D deficiency, including elderly, pregnant women, people with osteoporosis or obesity, people who have dark skin color, vegetarians and vegans. Seniors are advised to have their vitamin D levels checked regularly and, if necessary, take supplements under the guidance of a doctor.
Vitamin D is therefore an essential nutrient with numerous health benefits. Although it can be obtained from various sources, supplements may be necessary to fill shortages, especially during the winter months and for certain risk groups. Always consult a professional before starting supplements.
