Scientists have identified more than 30,000 edible plant species on earth so far.
Despite that rich variety, about 90% of the world’s grain and vegetable food supply comes from only 20 species.
Grains are grown for food in large quantities worldwide, and are considered staple crops.
Whole grains are a rich source of vitamins, minerals, and even protein.
But when it is refined and the bran and germ are removed, whatever that remains is mostly carbohydrate and lacks the majority of the other nutrients.
In other words, white bread and white rice have almost zero nutritional value.
The moral of the story? Eat your whole grains.
