Good health is important, and the physical and spiritual aspects of life affect each other. When one suffers, so does the other; when one improves, the other follows. The American diet has been described as too much and too little. We consume too much sugar and alcohol, while getting too few fresh fruits and vegetables, exercise, pure water, and self-control. This imbalance contributes to a national problem with obesity, which is linked to twenty diseases, some of them major afflictions. Self-control, a fruit of God's Spirit, is essential in addressing these issues. Educating oneself on health principles involves studying personal differences, as some individuals have low tolerance for certain foods like spices, fruits, vegetables, dairy, chocolate, sweets, or alcohol. Despite enjoying their flavors, consuming them can lead to discomfort, requiring limits to be set. Patience is critical, as recovery from poor health conditions may take years, though diligent and patient application can speed the body's repair process.

As we are learning, a perfect storm regarding health issues is building. Virtually all purity, as compared to the way things were when God created Adam and Eve, is lost. The air we breathe, the water we drink, and the food we eat are constantly becoming more defiled. If we fear God, we cannot ignore the warnings and flags being raised about these dangers, because He has given us a charge to glorify Him in our body and spirit, which are His. How can we glorify God in our body if we are knowingly feeding it poison? The problem with food contamination began to surface in the early sixties with the pasteurization of milk, a poor nutritional substitute for raw milk, impacting public health. In the seventies, warnings emerged about fruits and vegetables contaminated with pesticides and insecticides, alongside fluoridation and chlorination of water, and chemical additives in food for coloring, preserving, and enhancing taste. These toxins are difficult for our bodies to eliminate, leading to increased occurrences of degenerative diseases. Now, hybridization and genetic manipulation pose an insidious danger. Modern hybridized wheat, planted since the 1970s, triggers obesity and celiac diseases by artificially stimulating appetite. The average American is now 20 pounds heavier than in 1990, with projections of an additional 40 pounds by 2020, making the United States the most obese nation on earth. GMO corn, with its insect-killing Bt gene, is a major threat, banned in most European countries for its danger to human health, yet 50% of corn grown in the United States is GMO. This corn, along with GMO soybeans, is fed to cattle, passing the Bt gene into the meat we consume. Many processed foods contain GMO grains, transferring these risks to us. Additionally, GMO products include sugar beets, potatoes engineered with vaccines, tomatoes, papayas, zucchini, yellow squash, cotton, rapeseed for oil, and even aspartame, an artificial sugar produced through genetic combining. A GMO salmon is also on the horizon. Dairy cattle injected with the rGBH hormone further compound the issue. These products are widely available, yet labeling is banned, leaving consumers blind to the dangers. Avoiding them requires careful searching and higher prices for organic options, which many cannot afford, and growing one's own food is often impractical due to space and time constraints.

Ancient physicians recognized the vital importance of diet in preventing diseases. In the treatment of disease, the Hippocratic school attached great importance to diet, with the variations necessary in different diseases being minutely defined. Medicines were regarded as of secondary importance, but not neglected. In chronic cases, diet, exercise, and natural methods were chiefly relied upon. It should be a doctor's primary duty to teach people how to live in a healthy way, not to try to cure them after they become sick.

Diet, understood specifically through the discipline of fasting, forms the foundation for exploring how physical stewardship of the body—God's temple—mirrors spiritual transformation. Drawing on I Corinthians 3:16-17 and 6:19-20, the body is presented as the dwelling place of God's Holy Spirit, making dietary habits a matter of spiritual stewardship rather than mere physical health. Roderick Meredith's explanation of fasting as a natural, God-given cure is foundational: when the body is not overloaded with excess food, it can cleanse itself of toxins that cause sickness. This "house-cleaning" metaphor, echoed by Thomas Ryan and Brett and Kate McKay, illustrates how restricting diet allows the body to eliminate waste and restore hormonal and mental balance. Historical figures such as Hippocrates, Paracelsus, and Mark Twain are cited to affirm that dietary restriction through fasting has long been recognized as superior to medicine for healing. Central to this discussion is the concept of autophagy, described by Dr. Jason Fung as the body's natural process of recycling old, damaged proteins and cells, activated specifically by fasting. When food intake stops, the body shifts from burning glucose to burning stored fat, cleansing organs such as the liver, kidneys, and pancreas. This process directly counters conditions like diabetes, kidney disease, and Alzheimer's, all linked to insulin resistance caused by excessive sugar and glycogen. A personal account of adopting intermittent fasting—including extended liquid fasts, 36-hour "monk fasts," and reduced meal frequency with lowered carbohydrate intake—demonstrates how dietary change reversed dangerous blood sugar readings, avoiding the need for insulin prescription. Rachel Link's research is enlisted to confirm eight measurable benefits of fasting: improved blood sugar control, reduced inflammation, better heart health, enhanced brain function, weight loss, delayed aging, cancer prevention, and increased growth hormone production. These physical dietary benefits are explicitly framed as types pointing to spiritual realities. Just as autophagy destroys diseased cells to make way for renewal, spiritual fasting tears down carnal nature so that godly character, empowered by God's Spirit, can be built up. Romans 8:13, Psalm 51, Isaiah 1:18, and Isaiah 58:6 are connected to this pattern of breaking down the old to allow spiritual growth. The physical discipline of restricting diet becomes a training ground for submission to God, as described in James 4:7-8, where fasting demonstrates human dependency while inviting divine transformation. Ultimately, dietary fasting is positioned not as an end in itself but as a physical parallel to the mortifying of the flesh, the renewal of the mind, and the eventual transformation of the corruptible body into an incorruptible, spiritual one—linking the discipline of eating less to the larger biblical theme of sanctification and future glorification.

Food contamination represents a spiritual problem requiring a spiritual solution, not merely a physical one. Concerns about diet are not new to God's people; food-related issues appear in at least four places in the New Testament. What has changed is the scope of corruption—genetically-altered foods now follow earlier practices of hybridization and the use of chemicals to color, preserve, and enhance flavor, all done for marketing purposes rather than nutrition, and all dangerous to health. This corruption traces directly to Satan's influence over mankind. Satan is a real being, a deceiving, murdering destroyer and the high priest of death, who according to Revelation 12:9 has deceived the entire world—not only in matters of religion, but also within the food-producing industry itself. Because food contamination is universal, like air, and because eating is unavoidable, no one can physically escape this problem entirely. Attempting to do so risks consuming so much time and effort that it creates an idol between the believer and God in the pursuit of preserving physical life. God permits this Satanic influence, yet He promises in 1 Corinthians 10:13 that no temptation exceeds what one can bear, and that He always provides a way of escape. The solution therefore rests in one's relationship with God, requiring belief, right understanding, and faithful obedience through faith. This connects to broader themes concerning God's sovereignty and Israel's failure in the wilderness, where the people did not use faith to trust God despite witnessing His marvelous works. The New Testament Church is likewise on a pilgrimage, though a spiritual rather than physical one, being united to Christ as members of His spiritual body. As Ephesians 1:22-23 and 1 Corinthians 12:18 show, believers are placed within that body as it pleases God, joined not by physical blood but by a common spiritual Father and spirit. Ephesians 5:28-29 establishes that Christ nourishes and cherishes His church just as a husband cares for his own body, and since Christ is the same yesterday, today, and forever, the One who fed Israel daily for forty years in the wilderness will likewise provide for His people now—not through manna, but by making the food currently available acceptable to their bodies. The believer's responsibility is to remain thankful for what God provides, to exercise faith in asking Him to make that food acceptable for life and health, and to trust that He will do so according to that faith. Romans 14:17 reminds believers that the kingdom of God is not about eating and drinking but righteousness, peace, and joy in the Holy Spirit, cautioning against judging one another over dietary choices. While food matters less than faith and obedience to God's commandments, believers must still exercise discipline, avoid flaunting liberty, and diligently search out the best food available under their circumstances. Ultimately, resolving the food problem requires keeping the commandments, walking by faith, and faithfully asking God to make available food acceptable.
