Food is any material consumed to supply nutrition to an organisms. More specifically, food is generally of animal, plant or microbial origin, and has necessary nutrients, including vitamins, proteins, carbohydrates, sugars, or other macro-nutrients. The food chain describes the metabolic process by which species separate to obtain food and disperse it to ensure their survival.
Modern human beings have learned how to cook food, resulting in many variations of cooked and raw food over the world. Despite this, humans have been consuming food through the years using different methods of cooking, with most of these methods being unsuccessful in providing real food with all of its nutrients. Cooking eliminates most pathogens and enzymes, rendering food sterile and devoid of valuable nutrients. Moreover, during cooking, food becomes nutrient-poor, retaining only a very small percentage of its original nutrient content.
Eating a balanced and healthy diet may help reduce cardiovascular disease, diabetes, obesity, osteoporosis, high blood pressure, colon cancer, and certain types of cancer. Unprocessed foods contain a variety of chemicals that can contribute to these health issues. The chemicals in many foods leach into the bloodstream, contributing to toxicity and free radical damage in the body. Processed foods may also contain additives that have been proven to be or are suspected of being carcinogens, especially in people who are already prone to developing cancer. A diet based on unprocessed foods may help reduce risk of cancer and other health conditions. By eating a balanced diet made up of fruits, vegetables, lean meats, and whole grains, you can achieve good health.
