How to Eat Biblically: Permitted and Forbidden Foods

Eating biblically means following the food guidelines laid out primarily in the Old Testament, especially Leviticus 11, Deuteronomy 14, and several other passages that define which animals, plants, and preparation methods are acceptable. The rules are surprisingly specific: certain meats are permitted while others are off-limits, particular grains and fruits hold special status, and even how you prepare food matters. Here’s a practical breakdown of what biblical eating actually looks like.

Permitted and Forbidden Meats

The Bible divides animals into “clean” (permitted) and “unclean” (forbidden) categories, with clear physical markers to tell them apart.

For land animals, the rule is straightforward: the animal must both chew its cud and have split hooves. This permits cattle, sheep, goats, deer, bison, elk, and similar ruminants. It specifically excludes pigs (which have split hooves but don’t chew cud), camels, rabbits, horses, donkeys, and any four-footed animal with paws, including dogs, cats, and bears.

For seafood, the standard is fins and scales. Fish like salmon, cod, tuna, bass, trout, anchovies, and mackerel are all permitted. Shellfish of every kind is forbidden: no shrimp, lobster, crab, clams, mussels, oysters, squid, or octopus. Catfish, which lack true scales, also falls outside the boundary.

For birds, the Bible lists specific forbidden species rather than giving a simple physical test. The banned birds are mostly predators and scavengers: eagles, vultures, hawks, owls, storks, herons, and ostriches. Permitted birds include chicken, turkey, duck, goose, quail, pheasant, dove, pigeon, and partridge. The only permitted insects are certain types of locusts, crickets, and grasshoppers.

Blood and Internal Fat

Two ingredients are permanently off-limits regardless of the animal: blood and a specific type of internal fat. Leviticus 3:17 states this as “an eternal rule for all of your generations.” The blood must be fully drained from meat before eating. This is why kosher slaughter involves a specific draining process and why salting meat (to draw out residual blood) became standard practice.

The forbidden fat, called “helev” in Hebrew and usually translated as suet, refers specifically to the hard fat surrounding internal organs, particularly the kidneys. This isn’t the marbling within muscle meat or the fat under the skin. It’s the thick layer that covers the vital organs. Muscle fat and subcutaneous fat from clean animals are fine to eat.

Separating Meat and Dairy

Three times in the Torah, the same command appears: “You shall not boil a kid in its mother’s milk.” From this single prohibition, Jewish tradition built an extensive system of separating all meat and dairy products. Observant practitioners don’t eat cheeseburgers, cook chicken in butter, or serve cream sauce with beef. Many keep separate cookware, dishes, and even sinks for meat and dairy.

If you’re following these guidelines, the practical effect is that meals are either meat-based or dairy-based, never both. Foods that are neither meat nor dairy (fruits, vegetables, grains, eggs, fish in some traditions) are considered neutral and can be eaten with either category.

The Seven Species and Core Plant Foods

Deuteronomy 8:8 highlights seven agricultural products that formed the backbone of the ancient Israelite diet: wheat, barley, grapes, figs, pomegranates, olives (and olive oil), and dates. These weren’t just common foods. Their first fruits were the only offerings accepted at the Temple, and they remain ritually significant in Jewish practice today.

Each played a distinct role. Wheat and barley were the primary grains, harvested at different festivals. Grapes were eaten fresh, dried into raisins, and fermented into wine. Figs were a daily staple, often dried and pressed into cakes for storage. Olives were rarely eaten on their own but were pressed into oil used for cooking, lighting, and religious ceremonies. Dates were typically boiled into a thick syrup (“date honey”) that served as the primary sweetener, since refined sugar didn’t exist. Pomegranates were eaten fresh but also carried deep symbolic weight, appearing as decorations on priestly robes and Temple pillars.

Building meals around these foods, along with lentils, beans, nuts, and other whole grains, gets you close to what daily biblical eating actually looked like. The well-known “Ezekiel bread,” inspired by Ezekiel 4:9, combines sprouted wheat, barley, millet, spelt, lentils, and soybeans into a single loaf, reflecting the grain-and-legume combinations common in ancient Israelite cooking.

The Daniel Fast: A Plant-Based Approach

Not all biblical eating involves meat. In the book of Daniel, Daniel and his companions refuse the king’s rich food and instead eat only vegetables and water for a period of testing. This passage has inspired the modern “Daniel Fast,” a 21-day practice that cuts out all animal products, preservatives, sweeteners, and caffeine, limiting intake to fruits, vegetables, whole grains, legumes, nuts, and seeds.

A clinical study published in Lipids in Health and Disease tracked men and women through a 21-day Daniel Fast and found measurable drops in LDL cholesterol (from about 138 to 76 mg/dL), blood pressure (systolic pressure dropped from around 115 to 106 mmHg), and markers of inflammation. Body weight and composition didn’t change significantly, suggesting the benefits came from food quality rather than calorie restriction. The fast is often used as a spiritual discipline, but the physical effects are real and well-documented.

Shopping With Biblical Guidelines

If you’re trying to follow these principles using modern grocery stores, kosher certification symbols are your most reliable shortcut. These indicate that a product has been inspected and meets the biblical and rabbinical standards for clean eating. The most common symbol is the “OU” mark (a U inside a circle), which appears on thousands of products.

The variations tell you what category the food falls into:

  • OU (plain): The product contains no meat or dairy ingredients and wasn’t made on equipment used for either. This is called “pareve,” meaning neutral.
  • OU-D: The product contains dairy or was made on dairy equipment.
  • OU-Meat or OU-Glatt: The product contains meat or meat derivatives.
  • OU-Fish: The product contains fish ingredients. Per kosher rules, fish should not be cooked or eaten together with meat, but can be combined with dairy.
  • OU-P: Kosher for Passover and contains no leavened grain products.

Other common kosher symbols include the “K” inside a circle (OK Kosher), a “K” inside a star (Star-K), and a triangle with a “K” (various regional agencies). Any of these indicate rabbinical supervision of ingredients and production. For meat specifically, look for a kosher butcher or kosher-certified meat section, since the slaughter and blood-draining process can’t be verified from a standard grocery label.

Putting It Into Practice

A typical biblically aligned day might look like this: breakfast built around whole grains, fruit, nuts, and olive oil. Lunch centered on lentils or beans with vegetables and bread. Dinner featuring a clean meat (chicken, beef, lamb, or fish with scales) paired with vegetables and grains, but no dairy in the same meal. Snacks of figs, dates, pomegranates, or nuts fit naturally.

The practical shift for most people involves three main changes: eliminating pork and shellfish, stopping the combination of meat and dairy in the same meal, and choosing whole, unprocessed plant foods as the foundation rather than the side dish. Meat in the biblical diet was not the centerpiece of every meal. It was more occasional, with grains, legumes, fruits, and olive oil doing most of the daily nutritional work.

Wine appears throughout scripture as a normal part of meals and celebrations, though drunkenness is consistently condemned. Honey (both bee honey and date syrup) was the standard sweetener. Herbs like hyssop, coriander, cumin, dill, and mint are all mentioned in biblical texts and would have flavored everyday cooking.
