7. We do know that our bodies need protein. Apostle John Widtsoe in his book, The Word of Wisdom, wrote "It was shown in the history of plant science that plants contain all the necessary food substances: proteins, fats, starches and the carbohydrates, minerals...water [and] vitamins. The Great builder of the earth provided well for the physical needs of His children. Countless varieties of edible plants, vegetables, cereals, fruits and nuts are yielded by Mother Nature for man's daily food."
What sources of protein has the Lord provided naturally for our bodies, without considering the flesh of animals?
