The Increase of Interest in Vitamin D
Attention to vitamin D has grown dramatically in recent years, largely due to its relationship to several common diseases. Recent data indicate that deficiency of this micronutrient is present in many individuals, which underscores the need to better understand its functions.
Advances in the Knowledge of Vitamin D
Since its chemical structure was discovered in the 1930s, researchers have made considerable progress in their studies. Originally, the focus was on its role in maintaining calcium balance and bone health. However, this exploration has evolved, revealing a wider range of impacts on overall health.
Demystifying Erroneous Beliefs
Recently, a study by the Open University of Catalonia has highlighted a series of myths surrounding vitamin D, contributing to the confusion about its sources and benefits.
Dependence on Sunlight
It is a mistake to think that sun exposure is sufficient to obtain adequate amounts of vitamin D. According to the Spanish Society of Endocrinology and Nutrition, the deficiency can be attributed to several causes, including the lack of foods rich in this vitamin, the excessive use of sunscreen during the summer months, and the geographical altitude of many Spanish populations.
Food Myths
Another common myth is the idea that vitamin D can be obtained primarily through diet. In reality, the study indicates that around 80-90% of this vitamin comes from synthesis in the skin, while only 10-20% is provided by food. Plant sources, such as fruits and vegetables, do not contain fats, which are necessary for absorption.
Other Sources of Vitamin D
Disproving another belief, it should be noted that blue fish is not the only food that provides vitamin D. Experts point out that other foods such as mushrooms, egg yolk, whole milk products and liver are also significant sources of this essential vitamin.
The Role of Other Vitamins in Health
Vitamin D is just one of several vitamins that contribute to skin health. Vitamins C, E, A and B3 also play crucial roles. For example, vitamin C is known for its antioxidant properties and is found in brightly colored fruits and vegetables, which are essential for our daily health.
Futuristic Perspectives on Vitamin D
As we continue to delve deeper into vitamin D research, more and more discoveries are likely to challenge current notions. As a society, we will need to adapt our recommendations and practices to ensure that the general population meets their needs for this vital micronutrient.
