Folate levels decrease significantly during months with higher solar radiation
Thus, this team of scientists has determined a seasonal risk threshold among patients with folate deficiency, since, according to this study, folate levels decrease significantly in those months when solar radiation is higher.
A work performed in the Laboratory of Dermatological Photobiology of UMA, located in the Center for Medical and Health Research (CIMES), in which more than 100,000 patients from hospital units of Malaga were examined for five years.
"We have revealed that cycles repeat annually. The percentage of low values increases in summer by almost 3.5 percent in comparison to winter", explains researcher José Aguilera, who further says that folate levels are lower in men as compared to women, regardless of seasonality.
In view of these results, experts recommend that patients with folate values below 4ng/mL include folate-rich food, such as legumes or green vegetables, in their diet in summertime, and even take dietary supplements in case of low deficiency.
Folate is essential for cell division and growth. Low levels of folate are related to various conditions, such as megaloblastic anemia, neural tube defects and cardiovascular diseases. It is, therefore, a vitamin (vitamin B9) of vital importance for human beings, because, for example, it helps add iron to anemia or, in the case of newborns, prevent congenital disorders at birth, hence its importance during pregnancy.
Laboratory of Dermatological Photobiology
Since 2006, researchers from the University of Malaga have been working to find new trends in photoprotection, towards unprecedented lines that deepen in the sunlight-skin relationship, through the Laboratory of Dermatological Photobiology, which is unique in Spain.
Other R&D&I lines include the study on positive effects of vitamin D to prevent certain diseases, such as digestive and cardiovascular diseases, or the development of more efficient and long-lasting sunscreens, which are based on synthetic compounds but inspired by marine algae.
UV-DERMA, an app to know how long it takes the skin to burn
The researchers María Victoria de Gálvez and José Aguilera, members of this UMA laboratory, in collaboration with Fundación Piel Sana of the Spanish Academy of Dermatology, have also developed UV-DERMA, a mobile app that estimates the time our skin takes to burn when exposed to the sun.
Given its success, with more than 40,000 downloads, they are currently developing a new version translated into all languages so that it can be used around the globe.
