Mushrooms exposed to sunlight (or the UV light in sunlight) naturally generate vitamin D, which enhances calcium absorption and bone strength.
Farmers can give mushrooms 1-2 seconds of UV light after harvesting, generating your daily needs of vitamin D.
They are labelled as Vitamin D Mushrooms.
Even regular retail mushrooms have over 20% of your daily needs of vitamin D.
Placing regular mushrooms in direct sunlight for an hour (winter) will generate your daily needs of vitamin D in a serve (100g or three button mushrooms)
Vitamin D deficiency is common in Australia, especially during winter and in the southern regions.
Light-exposed mushrooms are a tasty and nutritious way to get your daily vitamin D needs.
