This discovery was quite surprising because it turns out that deadly diseases such as type 1 diabetes can actually be prevented by maintaining vitamin D intake.
Type 1 diabetes is a disease triggered by your immune system. A damaged immune system attacks insulin-producing cells in your pancreas. Around the world, one billion people lack vitamin D. This lack of vitamins is also often found in all ethnic groups of all ages.
Even though the sun is the best source of vitamin D that can be easily obtained, but sunscreen, clothing, skin pigmentation, and clouds prevent you from getting this intake. Other sources of vitamin D can come from foods such as milk and salmon.
