Vitamin D and sunshine
Vitamin D is essential for calcium absorption and many other biological processes. Lower levels of Vitamin D increase the rates of almost every disease like cancer, diabetes, osteoporosis, cognitiv...
Vitamin D supplementation
Getting vitamin D through supplementation shows zero benefits. A study over a period of 5 years found supplementing with Vitamin D had no impact on cancer, heart disease, or stroke.
A number of researchers now argue that people with high vitamin D levels are healthy not because of the vitamin, but because they get plenty of exposure to the sun. Vitamin D is just a marker of that fact.
Sunlight is good for you
A dermatologist discovered our skin uses sunlight to make nitric oxide, a molecule in the body that dilates blood vessels and lowers blood pressure.
He exposed volunteers to the equivalent of 30 minutes of summer sunlight without sunscreen. The result? The nitric oxide levels in the volunteers went up, and their blood pressure lowered. Because of the connection of high blood pressure to heart disease and strokes, this discovery can prevent millions of deaths globally.

Vegan fast food alternatives may often be worse for your health than the meat equivalent. It is good that people start to think about plant-based foods, but the danger lies in thinking t...
Plant-based protein menus
Plant-based protein sources are not the same as animal protein sources. Proteins are made up of amino acids which are the building blocks of every cell and hormone in our body. Meat protein contains all nine essential amino acids, whereas plant-based protein usually lacks at least one of the nine essential amino acids our body needs.
Unripe jackfruit makes a convincing choice for pulled pork alternatives, curries and burgers. But it is almost valueless if you needed protein since jackfruit consists of carbohydrates. Vegan burgers are made up of beans, but this is not a complete protein source.
Iron content
One study found that 25% of vegans (mainly women) had very low blood iron levels, compared to 0% of omnivores.
Plants like whole grains, legumes and spinach are high in iron but is not always the best type. Animal sources contain haem iron. Non-haem iron, found in plants, is not as well absorbed by the body.
