Foods Can Provide Health Promoting and Disease Protective Benefits

Historians and archaeologists have revealed that ancient civilizations all over the world recognized that certain foods could provide healthpromoting and disease-protective benefits. The historically documented use of certain foods and food extracts from dried plants for healing indicates that the early application of the knowledge about the health-giving functions of plant-derived compounds dates back thousands of years.

Natural plants are complex packages of biologically active compounds. The term “phytochemicals,” which means “plant-chemicals,” was coined to represent these thousands of plant-sourced compounds that have functional effects in animal tissues with subtle but profound effects on human health and immunity. With the recent discovery that superior immune function in humans is dependent on a broad array of these plant-derived chemicals, we can appreciate that food supplies us not only with the basic nutritive functions, but also with a secondary level of nutrition that adds a complex layer of disease resistance and longevity benefits. These secondary benefits have not been adequately appreciated until recently.

Our evolution in a world of edible plants allowed the human body to take advantage of the complex biochemical compounds found in plants that we could use to support superior functioning of our cells. In recent years we have discovered fascinating and enormously complex interactions within our cells—interactions by which a combination of phytochemicals support defensive and self-reparative machinery we never knew the human body possessed.

Phytochemicals are bioactive, plant-derived chemical compounds important for the growth and survival of the plant; they came about for the benefit of the plant world. However, the human immune system evolved dependent on these phytochemicals for its optimal functioning. Some people, objecting to the connotations of the word “chemical” (with its connection to artificial and toxic compounds), prefer to use the word “phytonutrients,” so you will often see those words interchanged. However, the word “chemical” is really what we might call agnostic, disconnected from particular dogma; and the widely established word “phytochemical” is the correct term to represent the broad array of these newly discovered compounds with complicated health effects.

Superior nutrition is the secret to Super Immunity, and it is relatively simple. It does not take years of study and contemplation to become an expert in human nutrition as long as you understand the principles that govern your basic food choices and food preparation. Just like the complicated and synergistic nature of the human immune system, natural plants are complicated and wondrous life forms; they contain thousands of intricate cells and biochemicals working in harmony. Animals and plants developed a fragile, interconnected, and symbiotic relationship on earth, and now human beings rely on plants for our health and survival. When studying the survival potential of animals and humans, we must realize that we are dependent on the health and quality of the food grown from the earth to sustain us: the health of the food we eat ultimately determines our own health. When we eat healthy food, we become healthy; when we don’t, we develop disease. Essentially, we are made from the food we eat. As it is commonly said, we are what we eat.

Unfortunately, when we cultivate nutritional deficiencies in our body over long periods of time, especially in our formative years, it can create cellular damage resulting in serious illnesses in later life that can be difficult to resolve. In addition, these deficiencies result in inferior immunity.

The great news for all of us is that the recent advancements in nutritional science have created an opportunity to earn great health via what we eat. And, as you will discover, it is not only the powerful compounds in foods such as berries and pomegranates that are so protective, but these compounds—when combined with those found in green vegetables, mushrooms, and onions in the diet—fuel the miraculous self-healing and selfprotective properties already built into the human genome, together resulting in Super Immunity.

A combination of these compounds is more effective than a single agent, even in a high dose. For example, taking a large dose of vitamin C or vitamin E is not very effective, especially if no deficiency existed prior to dosing. Likewise, although certain phytochemical compounds have more profound, long-acting, and powerful free-radical-scavenging effects than do known antioxidant vitamins such as C and E (more on antioxidants and free radicals later), supplementing with a hefty dose of a natural phytochemical extracted from a green vegetable would not offer as much protection as combining it with the hundreds of other beneficial compounds found in nutrient-rich foods. Acting cooperatively, these newly identified micronutrients work together to fuel an assortment of mechanisms that both prevent cell damage and also kill heavily damaged cells that cannot be adequately repaired, before they become dangerous to the body.

My “nutritarian” approach, which includes and mixes the most powerful and protective foods in the diet, is natural, comes without toxicity, and can prevent many human tragedies—not just revving up our immune system against infection and cancer, but also preventing heart attacks, strokes, and dementia.
