Pig Gelatin and Synthetic Pork: Kosher?

This week’s Torah reading (in the diaspora) is Shemini, famous for its list of kashrut laws. One of the things explicitly prohibited is, of course, pork meat (Leviticus 11:7). In recent times, a number of articles have circulated making a variety of different claims, such as that lab-grown pork might be kosher, or that pig gelatin is kosher, or even that all pork meat is actually kosher! Is there any validity to these claims? And why is pork forbidden to begin with?

Did the Torah Mean to Forbid Pork for Everyone?

Last year, an article made headlines arguing that the prohibition of consuming pork was only meant for Israelite priests, not the general public. This is based on the old idea that the entire Book of Leviticus was meant only for Levites. The argument is silly, for although Leviticus does have many laws intended only for priests, it also has a great many laws that obviously apply to all of Israel, including the well-known “love your fellow as yourself”. One simply has to look at how the laws are introduced to know whether they apply solely to priests or to the whole nation. When it comes to kashrut, the Torah states: “And Hashem spoke to Moses and Aaron, saying to them: Speak to the children of Israel, saying: ‘These are the creatures that you may eat among all the animals on earth…’” (Leviticus 11:2) Clearly, God commanded all of Israel when it comes to dietary laws.

Coffin Texts from the Middle Kingdom Period

Besides, abstaining from pork was actually common in other places across the Middle East. The Greek scholar Strabo (c. 63 BCE – 24 CE) noted that the ancient Phoenicians also abstained from pork, as did those who dwelled in the Arabian Peninsula, and their Muslim descendants to this day. Some believe this is because raising pigs requires a lot of water compared to raising other livestock—a precious commodity in the dry Middle East. Even the ancient Egyptians appear to have avoided pork meat at times. Perhaps the oldest reference is in the Coffin Texts that date as far back as the First Intermediate Period (2181-2055 BCE). Here, the evil god Set takes the form of a black pig, and is ultimately slain by the god Horus, to whom “the pig is an abomination”. Whatever the case, it is well-known that archaeologists working in Israel can easily differentiate an ancient Israelite site from a Philistine one by the conspicuous absence of pig bones in the former compared to the latter. There is no doubt that all ancient Israelites abstained from pork.

In his Guide for the Perplexed, where he sought to give logical explanation for the mitzvot, the Rambam (Rabbi Moshe ben Maimon, 1135-1204 CE) notes that one of the reasons pork is forbidden is because it is unhealthy (III, 48). Indeed, pork meat is the most likely to be contaminated with trichinosis and other parasites. Pigs are, by their very nature, quite unclean. They are omnivores and scavengers, and will eat absolutely anything, including dead animals (the consumption of which is prohibited by the Torah as well). Some also claim that pork meat has more toxins because pigs digest food extremely quickly and absorb just about everything into their bloodstream. Moreover, they have very few sweat glands, meaning they are less likely to clear those toxins from their system. While the idea of sweating as detoxification is controversial and often rejected by science, studies show that sweat does excrete a small amount of toxic waste, including heavy metals and compounds like BPA. Either way, the 13th century Sefer HaChinukh (on Mitzvah 73) already grappled with this issue and concluded that although secular society may argue pork meat is perfectly fine from a health perspective, “the true Healer that warns us against them is smarter than us, and smarter than the doctors.”

Meanwhile, Rashi (Rabbi Shlomo ben Itzchak, 1040-1105 CE) holds that the prohibition of pork is a chok, a divine law with no human rationale, just like the laws of the Red Cow or the prohibition of shaatnez, the wearing of wool and linen together in one garment (see his commentary on Leviticus 18:4). There are spiritual things at play that we simply cannot understand. More mystical texts do try to explain those spiritual mechanics: for one, it is said that a person absorbs the qualities of the animals they eat. This is why we do not eat predators or filthy animals, as we do not want to take on their aggressive or impure qualities. The kosher animals are essentially all herbivorous and docile, and it is those peaceful and calm traits that we want.

The Arizal (Sha’ar HaMitzvot on Ekev) further explains that kosher animals are those whose souls we are able to elevate. The act of slaughtering the animal in a kosher manner, reciting a proper blessing before eating it, and ingesting it into a holy human vessel allows those special spiritual sparks trapped within the animal to ascend to Heaven. The emphasis here is on holy human vessel, for if a person is unrefined and not righteous, with no connection to Heaven, they are unable to elevate any sparks at all. This is why, the Arizal explains, the Talmud states that an ‘am ha’aretz (an unlearned person or one who does not keep the mitzvot) shouldn’t eat any meat whatsoever! The Arizal notes that even a righteous, Torah-observant Jew should only eat meat on Shabbat and holidays, when a Jew is said to receive an additional soul. Without this extra spiritual power, it is nearly impossible to “rectify” the meat.

Is Pig Gelatin Kosher?

While it is clear that consuming pork is absolutely forbidden, what about pork by-products like gelatin? Gelatin is made by boiling and processing the bones, skins, and sinews of pigs (or cows, or fish) to produce the jelly substance used widely in the food industry. It is typically reduced to a powder that can be mixed with water. The powder itself gives no indication that it came from a pig, and certainly no longer has any taste of pork flesh. Is it still not kosher?

In Jewish law, a food that has been processed so thoroughly that it becomes tasteless (or inedibly bitter) is not considered to be “food” anymore. If one cannot enjoy from the flavour of the substance at all, then it is permitted, even if derived from a non-kosher animal (see Mishneh Torah, Yesodei haTorah 5:8). Such a substance is treated like an artificial chemical as opposed to an actual food. Similarly, something that is so putrid that even a dog would not eat it is no longer considered food.

In the case of pig gelatin, it is tasteless, and it is unlikely that a dog would consume raw gelatin powder. Even when mixed with water, many forms of raw gelatin have a horrible taste. This puts gelatin in the category of a chemical, rather than a food. Thus, using it as an additive would be permitted. Many authorities have ruled this way, including Rav Chaim Ozer Grodzinski (1863-1940) and Rav Tzvi Pesach Frank (1873-1960). Still, some modern authorities forbid pig gelatin, which is understandable considering the great aversion to all things pig in Jewish culture. Today, when there are alternatives like fish gelatin, or even carrageenan (derived from seaweed), there is no great necessity to consume products with pig gelatin.

Some medications are encased in gelatin capsules, and are fine for use.

Insulin that is derived from pigs falls under the same category. It would unarguably be permitted since it has a life-saving necessity for diabetics. Having said that, today most insulin is actually derived from genetically-modified bacteria, and recently scientists have even developed genetically-modified plants that grow human insulin!

Lab-Grown Pork in the Garden of Eden

In recent years, artificially lab-grown meat has become a reality. This type of meat is cultured in a lab from the stem cells of an animal. The meat is produced synthetically, without any need for raising or slaughtering animals. The potential benefits are tremendous, since lab-grown meat allows for only the very best tissues to be grown, and tweaked to have a perfect combination of nutrients. It prevents the need for large ranches and slaughterhouses, for the great amount of farmland used to raise food for the livestock, and all of the pollution that this entails. (Altogether, animal agriculture accounts for about half of all greenhouse gas emissions, and countless tons of sewage and toxic waste.) Scientists have successfully created lab-grown hamburgers, and an Israeli company (SuperMeat) is close to bringing cultured chicken to the market. Their chicken is healthier, uses 99% less farmland, 90% less water, and releases 96% less pollution. It appears that lab-grown meat is poised to take over in the coming decades. Is it kosher?

While the halachic issues are complex and remain to be settled by halachic authorities, some have already stated there shouldn’t be any problem with lab-grown meat. In fact, since it does not come from an animal, and requires no slaughter, it wouldn’t even be considered “meat” to begin with, and would likely be parve. This has been suggested by Rabbi Shlomo Aviner, the rosh yeshiva of Ateret Yerushalayim, as well as Rabbi Menachem Genack of the Orthodox Union. Thus, kosher cheeseburgers may yet be on the way.

More recently, Rabbi Yuval Cherlow (of Israel’s Tzohar Rabbinical Organization) stated that even lab-grown pork should be kosher. Once again, this is not an actual pig, but simply flesh cultured from a few pig stem cells. Such pork meat would never contain any blood, which the Torah states is what holds the animal’s nefesh (Leviticus 17:11), nor would it come from a living animal at all. From a Kabbalistic perspective, then, there would be no spiritual sparks to elevate. It seems lab-grown pork should be kosher.

Amazingly, Jewish texts long ago stated that a day will come when pork will be kosher. For example, the Ritba (Rabbi Yom Tov of Seville, c. 1260-1320 CE) writes in his commentary (on Kiddushin 49b) that the pig is called chazir in Hebrew because in the future God will hachziro, “return” it to Israel! While we have discussed in the past that certain Torah mitzvot will be abrogated in the Messianic Era, it seems unthinkable that pork should become kosher.

More problematic still, if the Messianic Era is a return to the Garden of Eden—as prophesied—than how can there be consumption of any meat at all? There was no death of any kind in the Garden of Eden, and consumption of meat was forbidden. It was only ten generations later that God permitted Noah to eat animal flesh. It should seem that the Messianic Era would be an entirely vegetarian one, like in Eden. At the same time, though, Eden is said to have contained all the pleasures of the world—so how can it miss the pleasure associated with eating meat? (Scientific studies confirm that eating meat boosts mood and happiness, and vegetarianism has been linked with higher rates of depression.) The World to Come should certainly be entirely pleasurable!

Perhaps lab-grown meat is the answer, for it beautifully solves all of the above issues. Lab-grown meat requires no animals to die, and allows everyone to consume every kind of taste—with the added bonus of being healthier for both body and planet. We can safely return to Eden without worrying about killing animals, without worrying about destroying the environment, and without worrying about giving up the foods we delight in.

Secrets for Living a Long Life

This week’s parasha is Ekev, continuing Moses’ final speech to the nation in the last 37 days of his life. In this parasha we find the second paragraph of the Shema. This paragraph ends by stating:

And you shall place these words of Mine upon your heart and upon your soul, and bind them for a sign upon your hand and they shall be for ornaments between your eyes. And you shall teach them to your children to speak with them, when you sit in your house and when you walk on the way and when you lie down and when you rise. And you shall inscribe them upon the doorposts of your house and upon your gates, in order that your days may increase and the days of your children…

The passage tells us to meditate upon God’s Word constantly, to never cease learning Torah, and teaching Torah. It tells us to place these wise words upon our hearts and souls, our arms and between our eyes, and onto our doorposts. It concludes by saying that doing so will lengthen the days of one’s life, and the lives of one’s children. God guarantees that persistent study and contemplation will lead to longevity.

Indeed, throughout history we see how our greatest Sages lived very long lives. Some of the earliest rabbis – Hillel, Yochanan ben Zakkai, Akiva – lived to 120 years, like several prophets before them, including Moses and Isaiah. In more recent times, the Lubavitcher Rebbe lived to 92 years, Rav Ovadia Yosef to 93, Rav Elyashiv to 102, and Rav Yitzchak Kaduri to 103 years – and some say 118!

The world-renowned Jewish neurologist Rita Levi-Montalcini said the secret to longevity is “minimal sleep, limited food intake, and always keeping the brain active and interested.” She would know: in addition to being one of the top scientists in the world, she was the first (and so far only) Nobel Prize winner to live over 100 years. Before calmly passing away from natural causes at 103, she still worked in her lab and served on the Italian senate! Her formula for longevity – little sleep, little food, and most importantly, busy brain – is probably true of every great rabbi in Jewish history.

Long before, the wise King Solomon taught the same thing in the ninth chapter of his Book of Proverbs. In this chapter, Solomon personifies Wisdom. He begins by saying that “Wisdom has built her house, hewing out her seven pillars.” He goes on to say that the First Wisdom is “awe of God” and “knowledge of holy things”. Simply collecting information in one’s brain is not enough; one must also be a righteous and Godly individual. A scorner or a proud person can never be truly wise, for such a person hates to be criticised, and will grow little. The real wise person is the one who loves those who critique and reprove him. “Teach the righteous, and he will increase in learning.” Ultimately, the pursuit of wisdom is the path to longevity, “For through me your days will be multiplied, and years of life will be added to you” (Proverbs 9:11).

Seven Pillars of Wisdom

King Solomon tells us that wisdom has seven pillars. He seems to identify the first of these pillars as being the study of God, holiness, and spiritual matters – in other words, Torah study. What about the other six branches of wisdom? What other studies are worth pursuing? While King Solomon does not explicitly say what they are, a later Kabbalistic text called Kol HaTor does describe them in its Sha’ar Be’er Sheva: mathematics, medicine, grammar, music, and three more that are described as “formations and syntheses”, “repair and integration”, and “how the physical interacts with the spiritual”. The last of these is clearly related to King Solomon’s First Wisdom (others say it is psychology, the study of the mind, which bridges the physical and the spiritual); the other two might be referring to general science (how things form) and perhaps mechanics or engineering.

Unfortunately, Kol HaTor is a very controversial text. It is supposed to be based on the teachings of the Vilna Gaon, but many reject this claim, especially because the book was only published in the last century. More problematic still is that the section called Sha’ar Be’er Sheva (which describes the seven wisdoms) is omitted from many manuscripts because it encourages the study of non-Torah subjects – something the ultra-Orthodox world is typically not fond of.

In any case, we see that the seven pillars of wisdom according to Kol HaTor actually resemble the classical branches of study at some of the earliest universities in Medieval times. These are often referred to as the “seven liberal arts”, and are comprised of three “humanities” and four “scientific arts”. The three humanities, consisting of logic, grammar, and rhetoric, were studied first. Once a person had a good grasp of these three, they moved on to study the more complicated scientific arts of music, arithmetic, geometry, and astronomy. The first three were known as the trivium, and the next four as the quadrivium. Interestingly, this is actually the origin of the English term for something being trivial, meaning very basic or unimportant, since the trivium consisted of basic entry-level subjects while the quadrivium was more advanced study.

Nests and Parents

The Torah mentions longevity with respect to two more specific mitzvot. The first is to honour one’s parents (Exodus 20:11 and Deuteronomy 5:15), and the second is known as shiluach haken, “sending away the mother bird” from its nest (Deuteronomy 22:7). The latter mitzvah applies if one happens upon a bird’s nest and wants to consume its eggs (or chicks).* The person should shoo away the mother bird first so that it does not see its offspring taken away. This is a clear sign of compassion on the parent bird. In this regard, the two mitzvot which promise longevity are actually related, both having to do with compassion and respect for parents.

If the “First Wisdom” is awe and fear of God, we can understand how respecting parents ties into it. The Ten Commandments were given on Two Tablets: the first listing five commands between God and man, and the second listing five commands between man and man. Honouring one’s parents is on the first tablet, and is considered a mitzvah not between man and man (as one would naturally assume) but between man and God! After all, the Talmud tells us there are three partners in the creation of a person: mother, father, and God. Disrespecting one’s parents is therefore akin to disrespecting God.

A Scientific Look at Longevity

Several years ago, the National Geographic Society backed a project (led by Dan Buettner) to identify and study the world’s “blue zones” – regions where people live the longest. They found a number of places where people regularly live well into their nineties and hundreds, and in good health, too. After studying these populations, they came to a number of conclusions as to how to increase longevity. The first was to do lots of natural exercise, ie. not going to the gym and pumping iron, but simply being active within one’s daily routine. They confirmed the importance of not overeating (phrasing it as the “80% rule”) and to consume more natural, plant-based foods as opposed to processed or meat-based ones.

All of these echo the Rambam’s teachings hundreds of years ago (Hilkhot De’ot 4:2, 14-15):

“A person should not eat until his stomach is full, rather he should stop about a quarter before he is filled… Overeating is to the body of a person like a poison, and it is the source of all sicknesses. The majority of sicknesses come upon a person either from eating bad foods or from filling the stomach and overeating, even with good foods…

“As long as a person exercises and exerts himself a lot, takes care not to eat to the point of being completely full, and keeps his bowels soft, illness will not come upon him and his strength will increase. And whoever sits comfortably and takes no exercise, even if he eats all the best foods and follows healthcare principles in other areas of his life, all his days will be full of pain and his strength will decline.”

Amazingly, the Blue Zone project also showed how huge of an impact religion and community has on longevity. They found that “belonging to a faith-based community” and going to a religious gathering at least once a week for prayer and connection added as much as fourteen years to one’s life! (See Dan Buettner’s full talk on longevity here).

Seven Pillars of Longevity

All of the above information can be neatly summed up in seven key points for living a long life. (1) Keeping the body naturally active, and (2) keeping the brain active and engaged. The study of spiritual matters takes priority, followed by subjects like math, music, and language arts. (3) Keep junk foods and processed foods to a minimum, and avoid overeating. (4) Be a part of a faith-based community, and (5) pray and meditate regularly. (6) Make sure to honour and respect parents, and (7) maintain an attitude of calm, compassion, and kindness in place of stress, anger, and selfishness.

The Blue Zone project narrows it down even further into four key points: have the “right outlook, move naturally, eat wisely, and belong”. Their website has a fun “age calculator” that estimates what your “biological age” is, your life expectancy, and how many extra years you’ve added (or lost) based on your habits.

Ultimately, if all else fails, the Torah mentions longevity four more times. In addition to the four explored above (two for honouring parents, one for the bird’s nest, and one for meditating on God’s Word), there are four that speak in general terms, promising long life for being attached to God and following His ways. This resonates with King Solomon’s final piece of advice in Ecclesiastes:

“The end of the matter, all having been heard: revere God, and keep His commandments; for this is the whole man.”

*It is important to note that, for some reason, it has become popular to believe that one needs to shoo away the mother bird of a nest even if a person does not need the eggs. Somehow, sending away the mother and taking the eggs is an “illogical mitzvah” that needs to be fulfilled. Such an interpretation is silly. The whole point is to have compassion on the mother bird. How would taking her eggs when there is no need for the eggs be compassionate? That would just be cruel! The Rambam writes that in most cases, this mitzvah is not going to be fulfilled since most birds and their eggs are not kosher – so why would anyone ever destroy a nest for no reason? See, for example, Moreh Nevuchim, III, 38:

“In most cases, this commandment will cause man to leave the whole nest untouched, because [the eggs] which he is allowed to take are, as a rule, unfit for food.”
