Vitamin D is a topic of interest year-round. 1 billion people around the world struggle to obtain the recommended amount of vitamin D. The greatest concentration of vitamin D comes from being directly exposed to the sun. And indeed, we make about 50%–90% of our vitamin D as a result of being exposed to the sun, with the rest coming from food or supplements.
Methods to Improve Vitamin-D in Mushrooms
Mushrooms are naturally good sources of vitamin D. For most on the plant-based diet, you might start to seriously consider using mushrooms to get your vitamin D. When mushrooms grow in the wild, they have access to sunlight, but white button mushrooms are often grown in the dark. This explains the difference between vitamin D levels in the two mushrooms.
Sunlight exposure : When you expose mushrooms to sunlight for up to an hour, the proportion of vitamin D in them increases substantially, so much so that they become as effective as vitamin D supplements.
Cooking : The best thing about mushrooms is that their vitamin D levels remain intact even after cooking. So, you can cook them without losing on any precious D. In fact, if any impact occurs, it only makes it easier to absorb the nutrient.
The deep interconnectedness of factors that will influence both your ability to absorb these nutrients as well as the quantity of vitamin D in a particular mushroom. Whether or not you use mushrooms as the main source of your vitamin D is your choice, and possibly the choice of your healthcare provider.
