Good health requires good nutrition. In turn, good nutrition requires eating of vegetables. Longevity studies showed that correlates of long life included consumption of fruits, vegetables, and whole grains, and a World Health Organization (2005) statement on diet recommended increased consumption of fruits and vegetables.
Individuals have a personal responsibility to eat foods that are good for their "temple" (body). Thus, one needs to exhibit discipline. One may prefer sugary foods and red meat, and disdain the taste of many vegetables, but good health requires a variety of food sources and particularly vegetables. One example of such discipline is seen in the Book of Daniel in the Bible. Daniel and his friends were captured by the king of Babylon during an invasion of Israel. Selected as court servants, they were to share in the king's fine foods and wine. But they objected, preferring vegetables (pulses) and water in accordance with their Jewish dietary restrictions. The king's chief steward reluctantly agreed to a trial. Daniel and his friends received their diet for ten days and were then compared to the king’s men. Appearing healthier, they were allowed to continue with their diet.
Another unification aspect revealed in terms of vegetables is the relationship between humans and nature. Humans have a relationship with a vast array of plants that are important for good nutrition. The relationship between humans and the environment is enhanced by the fact that the best nutrition involves consumption of a diversity of foods. A diet based solely on meat or solely on a particular plant will soon result in the breakdown of the body, as essential nutrients are missing. Rather, it is recommended that a wide variety of foods from a variety of sources be consumed. This brings humans into a broader relationship with many plants.
Human beings have used their creativity to improve upon varities of plants, to make them more nutritional, more productive, and more sturdy. However, the dark side of human nature, which Unification Thought attributes to separation from God, has also been displayed, as human beings, in the quest for greater profits, have sold vegetables with much of the nutrition removed, polluted the environment with greater and greater amounts of pesticides and herbicides, and pursued other actions that have not taken into account human health and future generations.
