What Should We Eat?

The dietary laws about “clean” and “unclean” meats are among the clearest instructions found in the Bible. For thousands of years these laws have been a striking mark of identity separating God’s people from the world (Leviticus 20:25–26). Consequently, for centuries, these same instructions have been a source of controversy and confusion among various religious groups who all claim to get their beliefs from the same book—the Bible. Some have felt that “these laws express God’s will” and as such are wise, reasonable, and beneficial dietary regulations revealing God’s care for the health of His people. This public health focus of those dietary laws was espoused by Maimonides, the great Jewish philosopher of the Middle Ages in Spain and many other notable scholars However, other theologians have openly referred to the Leviticus dietary guidelines as meaningless, repulsive, arbitrary and irrational ideas that originated in primitive superstitions and not in the mind of God. These theologians have confidently asserted: there are no logical explanations for many of the guidelines—that health was definitely not their purpose; that it is a waste of time for Christians to study this section of Scripture. They have asked, What has all this to do with religion? Some have even stated, “The Scriptures do not claim that health is a factor in the dietary laws, though possibly hygiene was a by-product. Yet God said His laws were for our good, prolonging our lives (Deuteronomy 5:29, 33; 10:13). His dietary ordinances were not arbitrary. Their purpose was to benefit us. That being so, why would God later inspire a New Testament that supposedly shows “Christ repealed all the Leviticus regulations on unclean meats and practices” ? Why would an all-wise Creator function in such a contradictory manner? If you have ever pondered such questions, perhaps it’s time you really looked into the subject to determine for yourself what the real truth of the matter is.

Prove All Things:

The God of the Bible challenges each of us to “prove all things; hold fast that which is good” (1 Thessalonians 5:21 KJV). The answers could change your life and immensely impact your health! The Scriptures reveal several important reasons for the dietary laws. In Exodus we learn that God chose the nation of Israel for a special purpose (Exodus 19:5–6). Interestingly, the dietary laws were designed to make the Israelites distinct from other nations. Why? God told Moses, “I am the Lord your God, who has separated you from the peoples. You shall therefore distinguish between clean beasts and unclean…. And you shall be holy to Me, for I the Lord am holy, and have separated you from the peoples, that you should be Mine” (Leviticus 20:24–26). God chose Israel for the purpose of becoming a model nation—a light and example to the world. “Therefore be careful to observe them; for this is your wisdom and your understanding in the sight of the peoples who will hear all these statutes, and say, ‘Surely this great nation is a wise and understanding people.’ For what great nation is there that has God so near to it, as the Lord our God is to us, for whatever reason we may call upon Him? And what great nation is there that has such statutes and righteous judgments as are in all this law which I set before you this day?” (Deuteronomy 4:6–8). God separated Israel from other nations so the results of His laws could be clearly seen by the other peoples and to show the wonderful benefits provided by His righteous ways. The dietary laws were also designed to promote wise management and efficient utilization of the environmental resources that God entrusted to mankind. The instructions about “clean” and “unclean” foods are important in fulfilling the commission given in Genesis 1:28 and 2:15 to “tend and keep” the earth. To rightfully understand the dietary laws, they must be seen in the context of God’s purpose.

Chew The Cud

Leviticus 11 and Deuteronomy 14 are the primary passages in the Bible that discuss this subject. These chapters give very specific information summarized in simple, easy-to-understand principles. Today, however, the discoveries of modern science are revealing just how practical and important these laws really are. Beginning in Leviticus 11:1–3, we read that “the Lord spoke to Moses and Aaron, saying… ‘These are the animals which you may eat among all the beasts’ that are on the earth… whatever divides the hoof having cloven hooves and chewing the cud.’” This describes plant-eating mammals (herbivores) classified as ruminants. A ruminant is “the name given to a grazing animal that has a highly specialized digestive system and splits the hoof’” (World Book Encyclopedia, 1995). These animals have four-chambered stomachs that convert grasses that are inedible to humans and other animals into nutritious, high quality protein products (meat and milk specifically) that humans can then use for sustenance. Examples of such clean animals would be all cattle, sheep, goats, deer, bison, moose, antelope, gazelles, caribou and giraffes. They are all herbivores that obtain their food by grazing or browsing on grasses and other plants. From the standpoint of wise environmental management, these guidelines make a lot of sense. Vast areas of the globe are covered by grasslands (savannas, veldts, pampas), which are often called marginal lands because they do not have enough rainfall to support the production of food crops like corn or wheat. “The only way billions of acres of grassland can be used for human benefit is via ruminants” (Dairy Council Digest, Jan.–Feb. 1973). Grass-fed animals also produce meat that has a lower fat content than grain-fed animals—which we now realize is a health benefit. The clean animals that God permitted His model nation to eat—designated simply by split hooves and cud-chewing—were designed to produce nutritious food in an economical and ecologically sound manner. These guidelines were given long before the sciences of ecology, economics and nutrition. This was one of the benefits that God wanted the world to see through the example of the nation of Israel.

Hold the Hog:

The dietary laws regarding cud-chewing beasts also prohibit the consumption of all carnivorous animals and omnivorous animals for very logical reasons. God created clean animals to provide food and by-products for human use. He created animals unsuitable for human consumption for other purposes. Carnivores, as beasts of prey play an important role in controlling the populations of other animals and rodents. As an example, wolves and mountain lions, which feed on herds of deer, control not only numbers, but also help maintain the health of the herd by culling out older, sick or infirm animals. That’s one reason we shouldn’t eat carnivores. They eat sick and dead animals and transmit diseases to humans. The pig or swine is specifically mentioned as being unclean and not permitted as human food (Leviticus 11:7–8; Deuteronomy 14:8). While some theologians have stated, “We do not know why the swine was forbidden” (Interpreter’s Bible), thousands of other writers and scientist have found numerous logical reasons related to ecology, economics, nutrition and public health. In the wild, swine are often nocturnal animals that root for food. Their nighttime feeding habits should have kept their contact with humans at a minimum. Domesticated pigs, however, have been used for centuries as scavengers around human settlements. Having an omnivorous animal around that could put on weight rapidly by eating anything from garbage to dead animals and human wastes—and that could later be slaughtered and used for food—has seemed like a pretty good arrangement to many peoples. But is it? Today, domesticated hogs are fed a diet composed mainly of corn and grain. However, as non-ruminants with digestive tracts similar to that of humans, pigs are unable to survive on grasses and thus have been ecological competitors with humans for the same types of food grains (such as wheat, corn and barley). In America about 28% of the corn harvested is fed to hogs. Basically, pigs enjoy eating the same types of food that people eat. This is not a wise use of resources. He foresaw that great herds of hogs would take life-sustaining grain out of the mouths of his people. Jesus Christ Himself did not feel it inappropriate to allow an incident that caused the destruction of a herd of pigs! “Now a herd of many swine was feeding there on the mountain. And they begged Him that He would permit them to enter them. And He permitted them. Then the demons went out of the man and entered the swine, and the herd ran violently down the steep place into the lake and drowned” (Luke 8:32–33). Would Jesus have allowed the destruction of someone’s valuable property, without cause, through carelessness or accident?

Let Us Not Eat Bugs!

One of the major diseases transmitted by swine and other unclean animals is trichinosis. It is caused by a small parasitic roundworm that gets into the muscle tissue of animals and humans. The disease has a global distribution and affects about 4% of the world’s population—nearly 240 million people. This is not surprising considering that “people throughout the world eat more pork than any other kind of meat. Americans consume about 80 pounds per person each year. It should be noted, however, that many carnivorous and omnivorous animals are infected with the parasite Trichinella spiralis. Bear meat, walrus and wild pigs have been significant sources of infections in humans for thousands of years. The list could also include squirrels, rats, cats, dogs, rabbits, foxes, horse meat and marine mammals. It is hardly an accident or coincidence that God prohibited the consumption of these animals by His divinely given dietary laws. Tapeworms, which afflict about 3% of the world’s population (about 180 million), are another serious health problem encountered ONLY when pork is eaten. While beef and fish can also contain other tapeworms that can colonize the human digestive tract and cause discomfort, the pork tapeworm is much more dangerous, the larva of the pork parasite, once inside the human intestine, can migrate through the tissues to the heart, eyes and brain—and can eventually cause death. With reference to pork tapeworm disease, the highest rates of infection are seen in countries where pork is a major part of the diet, such as Mexico, Latin America, United States, Spain, Portugal, Africa, India, southeast Asia, and China. Although the general advice for avoiding parasitic infections from pork and other unclean animals is to adequately cook the meat, the most effective way to avoid these diseases is to avoid eating unclean animals that do not have cloven hooves and do not chew the cud—as God instructed Moses and the Israelites 3,500 years ago. If only this portion of the biblical dietary code were applied today, the global burden of parasitic disease could be reduced by 800% within 1 generation!

Don’t Eat The Garbage Man:

Why did God prohibit eating certain foods? Was the Creator being capricious? Why should He be concerned? Is there a rational, logical basis for the Scriptures dealing with which foods are fit for human consumption? After dealing with edible land animals, the second major set of divine dietary instructions concerned aquatic creatures. In Leviticus we are instructed: ‘These you may eat of all that are in the water: whatever in the water has fins and scales, whether in the seas or in the rivers—that you may eat…. Whatever in the water does not have fins or scales—that shall be an abomination to you” (11:9, 12). Numerous and sometimes fanciful reasons have been proposed for these guidelines. While some Bible scholars recognize that the consumption of unclean organisms can be harmful others suggest that organisms without fins and scales resembled snakes and thus are abhorrent to eat (Interpreter’s Bible, 1953). One source stated that scripturally “unclean,” bottom-dwelling organisms were symbolic of living in sin and pollution, and that fins were symbolic of prayers that could lift us out of such situations (The Bible Commentary, Scribner, 1871). The discoveries of science, however, reveal in greater detail the wisdom and benefits of God’s plain instructions about appropriate food. Biblically “clean fish” are generally free swimming in bodies of water. Most “unclean” fish are either bottom dwellers or predatory scavengers. The prohibition against eating scaleless fish protects against the consumption of fish that produce poisonous substances in their bodies. A U.S. Navy survival manual comments, “All the important fish with poisonous flesh… lack ordinary scales…. Instead, these poisonous fish are covered with bristles or spiny scales, strong sharp thorns, or spines, or are encased in a bony box-like covering. Some have naked skin, that is, no spines or scales”. Many sea creatures listed as venomous (four sharks, 58 stingrays, 47 catfish, 57 scorpion fish, 15 toadfish, etc.) do not have true scales. Eels—nocturnal predatory scavengers that eat “almost any kind of food, dead or alive”—would also be considered unclean. Eel blood contains a toxic substance “which can be dangerous if it comes into contact with eyes or another mucous membrane. The biblical guidelines were designed to point people to the safest kinds of fish to eat.

A Different Purpose:

Shellfish, lacking both fins and scales, are clearly excluded by the biblical dietary laws. But why would lobsters, crabs, crayfish and shrimp, which are considered delicacies in many parts of the world, be prohibited? The answer lies in understanding the role they were designed to play in nature. Lobsters are “nocturnal” foragers. They are bottom walkers and predatory scavengers that scavenge for dead animals and other bottom-dwelling organisms and debris. They are usually caught in lobster pots “baited with dead fish. Lobsters have long antennae and tiny hair-like sensors all over their bodies “that can detect specific chemical molecules in the environment (released by decaying organisms), which can help the lobster identify and locate food, even in the dark. Lobsters have been observed to bury a dead fish and then dig it up later, at intervals, to eat a bit more of it. Crabs are referred to as “professional garbage hunters” and as “scavengers” that eat almost anything. The crab prefers dead fish, but will eat any carrion [dead], “putrefying flesh” (International Wildlife Encyclopedia). Common shrimp, a small, delicate relative of crabs and lobsters, live by day in the mud or sandy bottoms of bays and estuaries all over the world. However, they become active at night as predatory scavengers and are “bottom dwelling detritus feeders “eating dead and decaying matter” (International Wildlife Encyclopedia). These organisms were all created for a very important ecological purpose. They are, in essence, the “garbage collectors” or the “cleanup crew” for the bottoms of lakes, rivers, beaches, bays and oceans. They were not intended to be food for human beings. That is also why the consumption of raw, pickled or undercooked crabs, crayfish, snails and shrimp carries a significant risk of parasitic infections like liver flukes, which infect up to 80 percent of some rural populations in Southeast Asia and Africa.

Danger On the Half Shell:

There are also important and logical reasons why God created and then clearly labeled clams, oysters, mussels and scallops as unclean and inappropriate for human consumption. These creatures are found in lakes, streams and coastal areas around the world where they perform specialized roles. As stationary filter-feeding mollusks, they pump large amounts of water over their mucus-covered gills, trapping tiny pieces of food (silt, plant debris, bacteria, viruses) which they then eat. As a result, mussels and other animals feeding on microscopic particles are the ultimate scavengers of the sea. Filter-feeding organisms are the “vacuum cleaners” for aquatic environments. Their role is to purify the water. Once you understand the purpose for which God created shellfish, the reason they are unclean should become obvious. Just as you would be reluctant to make a meal out of the contents of your vacuum cleaner bag, A/C filter or in your septic tank, the decision to eat shellfish should also be considered carefully! Because their method of feeding is “ideal for concentrating bacteria in sewage,” in addition to collecting and concentrating pathogenic viruses, heavy metals and nerve toxins produced by plankton, these shellfish present a serious health hazard to consumers (International Wildlife Encyclopedia). How serious is the threat of disease? The American Food and Drug Administration has stated that “raw oysters, clams, mussels and pork, so savored by gourmets account for 85 percent of all food born illnesses” (FDA Consumer, June 1991). Outbreaks of cholera, typhoid, hepatitis A, Norwalk virus, salmonella and paralytic shellfish poisoning are just some of the health problems frequently linked to the consumption of these mollusks, In addition ALL hepatitis comes from “Unclean” food! Notices have been published that pregnant women, the elderly and “individuals with immune systems weakened by certain diseases (cancer, diabetes and AIDS) should… avoid eating or handling uncooked shellfish”. These dangerous and potentially life-threatening situations can be avoided by understanding and following the biblical dietary laws that prohibit eating marine organisms that lack fins and scales.

Birds to Bugs:

The final groups of organisms covered by the biblical code are birds, insects and reptiles. Essentially all the excluded fowl are either birds of prey or scavengers like vultures and seagulls. Carnivorous birds are important in controlling populations of other animals. Their dietary habits of eating the flesh and blood of their prey make these birds potential agents for transmitting disease. Predatory fish-eating birds tend to accumulate high levels of toxic chemicals in their bodies. Most of these birds are not important food sources for humans. Reptiles are also among the animals listed as unclean for human food (Leviticus 11:29–30; 42–43). Regarding Insects, only those from the locust/grasshopper family are permissible as food. These creatures are distinguished by having “strong hind legs for springing” and have been used, historically, as a food source in the Middle East.

Dietary Laws Abolished?

The biblical dietary laws are simple, rational, practical and profound. Long before human beings knew the details of disease-causing microorganisms, life cycles of parasites or global ecology, God revealed powerful principles that would protect the environment, provide safe, healthful food and prevent the spread of disease for anyone who would be willing to follow these instructions. The intent and benefits of these biblical guidelines have been acknowledged periodically in history. One scholar observed recently that “most of the laws can be clearly seen to tend toward public health. But if these laws are so logical and beneficial to mankind, where did the idea come from that they have been abolished? Why do Bible-believing Christians seem to be in the forefront of promoting this notion? The answer is found in interpretations that are read into scriptures found in Mark 7 and Acts 10. Studying the “evidence” is all the is needed to gain a clear understanding. In Mark 7, Jesus addressed a question about why His disciples ate without washing their hands according to ceremonial traditions followed by the Pharisees. Some Bible translations add words to Jesus’ answer in verse 19, suggesting that He did away with the dietary laws. However, these added words are not found in the original texts. Christ’s point was that orally ingested dirt does not spiritually defile a person since it does not enter the heart to influence attitudes. The dirt passes through the digestive tract and is eliminated. The subject of clean and unclean meats and the dietary laws are not being discussed in this chapter or in Matthew 15:10–20, which discusses the same event. In Acts 10, Peter is given a vision to help him understand God’s future plans for the Church. He was shown a group of unclean animals and told three times to eat. Each time he adamantly declined because he believed it was wrong. Now remember, this was the Peter who supposedly heard Jesus abolish the dietary laws earlier in Mark 7 and who was trained by Christ for 3 1/2 years and yet he was still under the clear impression that eating unclean meats was wrong! He was puzzled over the meaning of the vision (Acts 10:17) until three men came knocking at his door with a request to hear the Gospel explained, Normally Peter would not have associated with these men who were outside of the covenant community, because the Jews considered the Gentiles to be “unclean.” When Peter put the pieces together he concluded: “God has shown me that I should not call any “Gentile” common or unclean”. Peter does not conclude in this chapter, or anywhere else in the New Testament, that the dietary laws were to be abolished. The so-called evidence is simply not there! Neither Jesus Christ nor Peter abolished these God-given guidelines.
