Do You Really Want to Eat That?

Douglas S. Winnail

Why did God prohibit eating certain foods? Should you follow those same instructions today?

The dietary laws about “clean” and “unclean” meats are among the most unique yet puzzling instructions found in the Bible. 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.

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 who would be attracted to Him by the wonder­ful benefits provided by His righteous ways. “My son, do not forget my law, but let your heart keep my commands; for length of days and long life and peace they will add to you” (Proverbs 3:1–2). God’s intention was that other nations would want to follow the example of the Israelites when they saw the wisdom and happiness of living according to God’s instructions─which would include physical well-being and freedom from disease (Deuteronomy 4:40; 7:12-15)!

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 for all humanity.  While many assume the Bible is simply a book written for religious contemplation and inspiration, the biblical dietary laws actually encompass very important public health principles that were recorded thousands of years before the scientific foundations for those principles were discovered.

Stay ON the Grass!

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. As one commen­tary observed, “These were rule-of-thumb laws that God gave in His wisdom to a people who could not know the reason for the provision” (Expositor’s Bible Commentary, vol. 2, p. 569). Today, however, the discoveries of modem 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) that people can then use for food. 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 rangelands (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 millions of acres of rangeland 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. Raising meat animals on grass and other plants is also much more economical.

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 were ever heard of. This was one of the benefits that God wanted the world to see through the example of the nation of Israel.

Hold the Bacon

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. 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 may eat sick 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), other writers find 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” (New Standard Encyclopedia, 1993). 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 20 percent 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 in a world where an exploding human population is out­stripping our capacity to produce food. Probably this is another reason why God does not want us to eat pigs. He foresaw that great herds of hogs would take life-sustain­ing grain out of the mouths of poor people!

Jesus Christ Himself did not feel it inappropriate to allow an incident that caused the destruction of a commercially raised herd of pigs! “Now a herd of many swine was feeding there on the mountain. And they [demons] 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 Worms!

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 1 percent of the world’s popula­tion—nearly 60 million people (Gerald Tortora, Microbiology, 5th ed., 1995). This is not surprising con­sidering that “people throughout the world eat more pork than any other kind of meat” (World Book Encyclopedia, 1995). 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 (Baron, Medical Microbiology, 1993). The list could also include squirrels, rats, cats, dogs, rab­bits, foxes, horse meat and marine mammals (Nestor, Microbiology 1995; Benenson, Control of Communicable Diseases in Man, 12th ed., 1975). 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 percent of the world’s population (about 180 million), are another seri­ous health problem encountered when pork is eaten (Tortora). While beef and fish can also contain tape­worms that will 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 (Morello, Microbiology in Patient Care, 5th ed., 1994). 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, Spain, Portugal, Africa, India, southeast Asia, and China” (Baron, Medical Microbiology, 1994).

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 dramatically reduced within a generation!


Don’t Eat the Cleanup Crew

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 (Expositor’s Bible Commentary, 1990), 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 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” (Survival on land and Sea, 1944).

Many sea creatures listed as venomous (four sharks, 58 stingrays, 47 catfish, 57 scorpion fish, 15 toadfish, etc.) do not have true scales (Caras, Venomous Animals of the World, 1974). Eels—nocturnal predatory scavengers that eat “almost any kind of food, dead or alive”—would also be considered unclean (International Wildlife Encyclopedia, 1990). Eel blood contains a toxic substance “which can be dangerous if it comes “into contact with eyes or another mucous membrane” (Encyclopedia of Aquatic Life, 1988).

The biblical guidelines were designed to point peo­ple to the safest kinds of fish to eat. However, care must be taken—even clean fish should be adequately cooked before eaten. Raw fish (such as sushi or sashimi) or poor­ly cooked fish can transmit several kinds of parasitic tapeworms and flukes (Black, Microbiology, 1993).

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 (Encyclopedia Americana, 1993). They are “bottom walkers” and “predatory scavengers” (Encyclopedia of Aquatic Life) that “scavenge for dead animals” and other bottom-dwelling organisms and debris  (Encyclopaedia Britannica, 1995). 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 (New Standard Encyclopedia, 1993)! Lobsters have been observed to bury a dead fish and then dig it up later, at intervals, to eat a bit more of it (International Wildlife Encyclopedia).

Crabs are referred to as “professional garbage hunters” and as “scavengers” that eat almost anything. “The edible 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]” (Encyclopedia of Aquatic Life).

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 under-cooked 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 (Black).

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 (Encyclopedia Americana, “Mollusks”). As a result, “mus­sels and other animals feeding on microscopic particles are the ultimate scavengers of the sea” (International Wildlife Encyclopedia). 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 or the material that collects on your furnace 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, Black).

How serious is the threat of disease? The American Food and Drug Administration has stated that “raw oys­ters, clams and mussels—so savored by gourmets— account for 85 percent of all the illnesses caused by eating seafood” (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 (U. C. Berkeley Wellness Letter Feb. 1994).

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” (Consumer Research, July 1993). 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 (Leviticus 11:13–19; Illustrated Bible Dictionary, vol. 1, 1980). Carnivorous birds are important in controlling populations of other animals. Their dietary habits of eating the flesh and blood of their prey—carrion—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 (vv. 21–23). These creatures are distinguished by having “strong hind legs for springing” (Expositor’s Bible Dictionary) 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... the laws were won­derfully fashioned by God for the general health of the nation” (Expositor’s Bible Commentary, 1990, pp. 529, 569).

But if these laws are so logical and beneficial to mankind, where did the idea come from that they have been abolished? The answer is found in interpretations that are read into scrip­tures found in Mark 7 and Acts 10. Studying the “evi­dence” is instructive.

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 preserved Greek texts. The translators put words into Jesus’ mouth that He did not say. Christ’s point was that orally ingested dirt does not spiritually defile a person since it does not enter the heart to influence attitudes (vv. 18–23). 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. Read these events for yourself in several different translations).

In Acts 10, Peter is given a vision to help him under­stand God’s future plans for the growth of 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 (vv. 13–16). Now remember, this was the Peter who supposedly heard Jesus abolish the dietary laws in Mark 7 (notice v. 2) and who was trained by Christ for three-and-one-half years—and yet he was still under the clear impression that eating unclean meats was wrong! He puzzled over the meaning of the vision (Acts 10:17) until three Gentile men came knocking at his door with a request to hear the Gospel explained (vv. 21–27). 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 of this little puzzle together he concluded: “God has shown me that I should not call any man common or unclean” (v. 28). He per­ceived that God intended the Gospel to go also to the Gentiles and that they were to come into the Church on equal footing with anyone coming from a Jewish back­ground. 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.

Ulterior Motives?

If the evidence for Christ and the Apostles abolishing the dietary laws is so weak—in fact, is totally non-exis­tent—where did this idea originate that has circulated so widely through the Christian community? The clues are to be found in the social, political and religious factors that influenced church doctrines of the second century AD (cf. Dr. Samuele Bacchiocchi, From Sabbath to Sunday, 1977, chap. 2).

It is generally acknowledged that the early Christians continued to observe many of the so-called laws of Moses—actually the clear teachings of the Bible (cf. Luke 4:16; Gibbon, Decline and Fall of the Roman Empire, chap. 15). However, as more Gentiles came into the Church they had to contend with strong anti-Jewish feelings that surged through the Roman Empire at that time. As a result of the attacks and ridicule heaped on Jewish customs by Latin and Greek authors; “many Christians severed their ties with Judaism” (Bacchiocchi, p. 185).

Many Gentile Christians attempted to “radically differentiate” themselves from anything that appeared to be Jewish. They wanted to appear as distinct and sepa­rate from the Jews. In their attempts to create a new identity they began to substitute new customs (many borrowed from the surrounding pagan culture) for their original biblical (so-called Jewish) practices (Bacchiocchi, chap. 2; Durant, Caesar and Christ). This included replacing the Sabbath with Sunday, the Passover with Easter and, in all probability, abolishing the dietary laws. As Dr. Bacchiocchi points out, early “Christian” writers developed some very novel ways of interpreting Scripture in an attempt to establish a bibli­cal foundation for their new practices. They also sought to undermine the value of the Jewish practices described in the Bible (p. 183).

From Here to Eternity

One of the unfortunate consequences of the aver­sion to the dietary laws, spawned in the turmoil of the second century AD, has been that millions of people have suffered and died of diseases they contracted by eating food that God never intended people to eat.

Somehow, the plain, simple statement in the Bible that Satan would deceive the whole world (Revelation 12:9) has been overlooked or conveniently forgotten. This deception has included the belief that theological, rational and beneficial instructions about diet, which God gave to Israel so it could become a model nation for the rest of the world, have been abolished and are no longer valid.

This situation, however, is going to change. When Jesus Christ returns to this earth there is going to be a “restitution of all things” (Acts 3:20–21), including the dietary laws found in the Bible. Prophecies in Isaiah 65:1–10 and 66:15–20 reveal that the returning Savior of mankind is going to correct mistaken notions that He or anyone else has done away with these beneficial laws. People will be given an opportunity to learn why God estab­lished His laws and to experience the benefits of living in harmony with these divinely inspired principles (Isaiah 2:2–3). The Bible also indicates that when this restoration occurs it is going to last as long as physical beings need guidelines to regulate physical behavior (9:6–7)!

Fortunately, you do not have to wait for the Second Coming of Christ to begin following the instructions of your Creator. You can start today. Individuals whose minds have been opened to the real meaning of the Scriptures are going to have the opportunity to share these life-preserving principles with all humanity (Isaiah 30:20–21).

Those who develop a working knowledge of the applications and benefits of God’s way of life are going to reign with Jesus Christ in the Kingdom of God (Revelation 11:15; Daniel 2:44). The dietary laws are part of God’s plan for well being. They are still appli­cable today, and they will be fundamental instruction for healthy living in Tomorrow’s World.
