According to biblical accounts, God's original diet for humanity was entirely plant-based, but this guidance evolved significantly across different covenants. This article explores what is the proper human diet according to the Bible, examining different periods of Scripture to provide a complete overview for modern believers.

Quick Summary

The Bible outlines dietary guidelines from Genesis's plant-based start to later permission for certain meats after the Flood. It details Old Testament clean and unclean laws, contrasting them with the New Testament's emphasis on freedom in Christ, gratitude, moderation, and glorifying God with one's body.

Key Points

Genesis Diet: The original biblical diet for humans consisted of a plant-based intake of fruits, grains, nuts, and seeds (Genesis 1:29).
Post-Flood Expansion: After the Flood, God permitted the consumption of meat but forbade the eating of blood, indicating a shift from the original plan (Genesis 9:3-4).
Old Testament Laws: The Mosaic Law introduced detailed rules distinguishing clean animals (like cattle with split hooves) from unclean ones (like pigs and shellfish) for the Israelites (Leviticus 11).
New Testament Freedom: Jesus declared all foods clean, fulfilling the ceremonial aspects of the Old Covenant, and the New Testament emphasizes that food does not defile a person (Mark 7:19).
Modern Principles: For Christians, a proper diet is guided by principles of moderation (avoiding gluttony), gratitude (receiving all with thanksgiving), and honoring the body as a temple of the Holy Spirit (1 Corinthians 10:31, 6:19-20).
The Daniel Fast: The Daniel fast is a modern, plant-based dietary discipline based on Daniel's example, used for spiritual focus rather than a commanded rule.

The Original Covenant: The Genesis Diet

In the beginning, as recorded in Genesis, God provided a specific diet for humanity, consisting of fruits, grains, nuts, and seeds (Genesis 1:29). This established a plant-based diet in a world before sin.

The Shift After the Flood

Following the great flood, God expanded the dietary rules, allowing the consumption of meat but with the restriction against consuming blood (Genesis 9:3-4).

Old Testament Dietary Laws: Clean and Unclean

For Israel, God instituted specific dietary laws detailed in Leviticus 11 and Deuteronomy 14, categorizing animals as "clean" (permissible) or "unclean" (forbidden) to set them apart. Clean land animals had a split hoof and chewed cud. Aquatic animals needed fins and scales. Many birds, especially scavengers and birds of prey, were forbidden, though certain insects were exempted. Prohibitions also included eating animal fat and blood.

New Testament Principles: Freedom in Christ

The New Testament fundamentally changed the application of these ceremonial laws. Jesus declared all foods clean (Mark 7:18-19). Peter's vision in Acts 10 reinforced this (Acts 10:15). Paul taught in 1 Timothy 4:4 that "everything God created is good, and nothing is to be rejected if it is received with thanksgiving". The emphasis shifted to glorifying God in all things and not causing others to stumble (1 Corinthians 10:31, Romans 14:17).

Biblical Eating Beyond the Law: The Role of Principles

While Old Testament food laws don't apply to Christians, principles guide a proper diet.

The Daniel Fast: A Principle of Discipline

Inspired by Daniel 1, the Daniel Fast is a plant-based discipline often used for spiritual focus and self-control, not a commandment.

Moderation and Gratitude

The Bible warns against gluttony (Proverbs 23:2) and emphasizes moderation and thankfulness. Believers are called to glorify God in what they eat and drink (1 Corinthians 10:31).

Your Body as a Temple

Treating your body as a temple of the Holy Spirit (1 Corinthians 6:19-20) is a principle that extends to making healthy dietary choices to honor God.

Comparison of Old and New Testament Dietary Approaches


Aspect	Old Testament Approach	New Testament Approach
Basis	Part of the Mosaic Law; a ceremonial distinction for Israel.	Part of Christian liberty; ceremonial laws fulfilled in Christ.
Scope	Comprehensive list of clean (allowed) and unclean (forbidden) animals.	All foods are declared clean and can be received with thankfulness.
Focus	On what enters the mouth (the physical food itself).	On the heart and conscience; what comes out of a person defiles them.
Purpose	To set Israel apart as a holy nation; health promotion was a secondary benefit.	To glorify God through stewardship, moderation, and gratitude, promoting spiritual and physical health.
Flexibility	Rigid rules with specific classifications.	Guiding principles allowing for greater personal freedom and discernment based on faith and conscience.

Conclusion

In conclusion, the biblical view of a proper diet evolves from Genesis's plant-based start, through the Old Testament's specific laws for Israel, to the New Testament's emphasis on freedom in Christ. While Old Testament food laws are not binding for Christians, principles of moderation, gratitude, and honoring God with our bodies remain relevant. A proper biblical diet today is guided by a heart seeking to glorify God in all aspects of life, including eating and drinking.

Frequently Asked Questions

No, the New Testament indicates that Old Testament dietary laws are not binding on Christians. Jesus declared all foods clean (Mark 7:19), and Peter's vision in Acts 10 confirmed this. The focus for believers shifted from ceremonial law to principles of conscience and glorifying God.

This means that the distinction between ceremonially clean and unclean foods from the Mosaic Law is no longer required for righteousness or salvation for believers in Christ. The external act of eating does not defile a person, but rather the inner intentions and state of their heart do.

Under the Old Covenant, eating pork and shellfish was forbidden for the Israelites. However, under the New Covenant, Christians are not bound by these specific dietary restrictions and are free to eat them, provided it is done with a thankful heart and without causing offense to others.

The Daniel Fast, a plant-based diet inspired by the prophet Daniel, is a spiritual discipline, not a required dietary rule. It is a voluntary choice for a period of time to focus on prayer and spiritual growth by abstaining from certain foods.

The Bible does not prohibit drinking alcohol entirely, but it strongly warns against drunkenness and excess (Proverbs 23:20-21). For some, abstaining entirely may be the wisest choice (Romans 14:21), and Jesus himself was known to drink wine.

A Christian should approach food with gratitude, moderation, and a desire to glorify God. It's about respecting the body as a temple and not allowing food to control you, rather than focusing on a strict list of allowed and forbidden items (1 Corinthians 10:31, Romans 14).

The New Testament does reiterate the importance of abstaining from blood and food sacrificed to idols (Acts 15:29). However, modern interpretation focuses more on the principles of not harming one's health and not causing a brother or sister to stumble, rather than a strict legalistic adherence to the original command.
