About fifty percent of Adventists today are lacto-ovo vegetarians. There are about 2 million Adventists throughout the world, with about a quarter of them living in the United States. The Seventh-Day Adventists are strong promoters of good health. They have their own publishing company and produce many books and other publications. They also have many hospitals, natural food stores, and vegetarian restaurants. In addition, they have an institution of higher education, Loma Linda University.

Several studies have found that Adventists are significantly healthier than the general population. Vegetarians owe much to Seventh-Day Adventists, since much of what is now known about health effects of vegetarianism comes from their studies.

Quotes:

God gave our first parents the food He designed that the race should eat. It was contrary to His plan to have the life of any creature taken. There was to be no death in Eden. The fruit of the trees in the garden was the food man's wants required. - 1864

The majority of the diseases which the human family have been and still are suffering under, they have created by ignorance of their own organic health, and work perseveringly to tear themselves to pieces, and when broken down and debilitated in body and mind, send for the doctor and drug themselves to death. - 1866

The diet of animals is vegetables and grains. Must the vegetables be animalized, must they be incorporated into the system of animals, before we get them? Must we obtain our vegetable diet by eating the flesh of dead creatures? God provided fruit in its natural state for our first parents. He gave to Adam charge over the garden, to dress it, and to care for it, saying, "To you it shall be for meat." One animal was not to destroy another animal for food. - 1896

Let our ministers and canvassers step under the banners of strict temperance. Never be ashamed to say, "No thank you; I do not eat meat. I have conscientious scruples against eating the flesh of dead animals. - 1901

Flesh was never the best food; but its use is now doubly objectionable, since disease in animals is so rapidly increasing. - 1902

Animals are becoming more diseased and it will not be long until animal food will be discarded by many besides Seventh-day Adventists. Foods that are healthful and life sustaining are to be prepared, so that men and women will not need to eat meat. - 1902

Vegetables, fruits, and grains should compose our diet. Not an ounce of flesh meat should enter our stomachs. The eating of flesh is unnatural. We are to return to God's original purpose in the creation of man. - 1903

The moral evils of a flesh diet are not less marked than are the physical ills. Flesh food is injurious to health, and whatever affects the body has a corresponding effect on the mind and the soul. Think of the cruelty to animals meat-eating involves, and its effect on those who inflict and those who behold it. How it destroys the tenderness with which we should regard those creatures of God! - 1905

Animals are often transported long distances and subjected to great suffering in reaching a market. Taken from the green pastures and traveling for weary miles over the hot, dusty roads, or crowded into filthy cars, feverish and exhausted, often for many hours deprived of food and water, the poor creatures are driven to their death, that human beings may feast on the carcasses. - 1905

It is a mistake to suppose that muscular strength depends on the use of animal food. The needs of the system can be better supplied, and more vigorous health can be enjoyed, without its use. The grains, with fruits, nuts, and vegetables, contain all the nutritive properties necessary to make good blood. These elements are not so well or so fully supplied by a flesh diet. Had the use of flesh been essential to health and strength, animal food would have been included in the diet appointed man in the beginning. - 1905

Those who eat flesh are but eating grains and vegetables at second hand; for the animal receives from these things the nutrition that produces growth. The life that was in the grains and the vegetables passes into the eater. We receive it by eating the flesh of the animal. How much better to get it direct by eating the food that God provided for our use! - 1905
