What is Nutritional Pharmacology?

Back in the 1980s, a scientist at Syntex Research in Palo Alto, California by the name of Gene A. Spiller defined nutritional pharmacology as:

“The study of substances found in foods that might have a desired pharmacological effect when fed in higher concentrations and/or in purified or chemically modified form even though these compounds might not be nutrients per se.”

In his definition, Mr. Spiller was referring to the fact that, when taken in larger amounts than normally present in our diets, certain food components exercise an effect that cannot be considered either nutritional or physiological. Instead, the effect is classified as pharmacological.

A few substances that Mr. Spiller considered to be derived from nutritional pharmacology research include:

  •      Concentrated fiber polymers as bulking agents (Psyllium seed, gums, etc.)
  •      Modified retinoids (Vitamin A-related compounds) in the prevention of carcinogenesis
  •      Modified Vitamin D for certain bone diseases
  •      Sterols for the control of cholesterol absorption
  •      Choline in brain disorders associated with deficient central cholinergic tone
  •      Trisaccharides in hepaticcoma
  •      Gums in adult onset diabetes

Dr. Spiller’s initial findings and hypothesis would eventually pave the way for a plethora of research and studies regarding the use of minerals, vitamins, botanicals, and phytochemicals as nutritional supplements that affect specific functions or diseases (The American Journal of Clinical Nutrition, 1980).


Nutritional Pharmacology at Work

The topic of nutritional pharmacology emerged in the 1990s in a series of studies conducted in relation to burn victims, HIV, and inflammation, with promising results.

Burn Victims & Amino Acids

Burn victims typically experience painful and extremely harmful pathophysiological alterations including extensive nitrogen loss, malnutrition, an increased metabolic rate, and immunologic deficiency. As a result, these alterations predispose burn victims to more frequent infection, decreased chance of wound healing, longer hospital stays, and higher death rates.

However, with proper nutritional support, these effects can be prevented or decreased. Studies have shown that, if administered soon after injury in quantities two to seven times the normal amount, dietary components such as glutamine, arginine, and (n-3) fatty acids can have beneficial pharmacological effects on the alterations burn victims typically experience (The Journal of Nutrition, 1998).

Flavonoids & HIV

An article published in the American Journal of Clinical Nutrition titled “Nutrition & Pharmacology: General Principles and Implications for HIV”, Daniel J. Raiten sheds light on the interaction between food, nutrition, and drug metabolism in the prevention, care, and treatment of HIV.

Raiten defines nutrition as “the sum total of the processes involved in the taking in and use of food substances through which growth, repair, and maintenance of activities of the body as a whole or in any of its parts are accomplished.” He establishes the primary processes of nutrition as ingestion, digestion, absorption, metabolism, functional use of dependent systems, and excretion and claims that each of these processes are integral to how the body takes in and uses nutrients and other food components.

One group of substances that was of particular interest to those studying nutritional pharmacology in relation to HIV was the flavonoid group. According to Raiten, “flavonoids are a group of substances that occur naturally in fruit (including cocoa), vegetables, beverages (tea, wine), and many dietary supplements (ginkgo biloba) or herbal remedies.”

Research about flavonoids has shown that this group has beneficial effects on a variety of different health conditions, including HIV. Flavonoids significantly affect the activity of CYP – the most abundant isoform of the cytochrome system in the human liver, which is responsible for the metabolism of approximately 60% of HIV-related drugs (The American Journal of Clinical Nutrition, 2011).

Omega-3’s as Anti-Inflammatories

Many studies have been conducted assessing the benefits of supplementing fish oil in diets of humans suffering from inflammatory and autoimmune disorders such as Crohn’s disease and rheumatoid arthritis. Fish oil is high in omega-3 fatty acids, which have shown to be successful in the management of inflammatory and autoimmune diseases in both humans and animals due to their anti-inflammatory properties.

According to a study conducted by the Center for Genetics in Washington DC, fish oil has revealed to have a significant benefit in treating ulcerative colitis, Crohn’s disease, psoriasis, arthritis, multiple sclerosis, and migraine headaches (US National Library of Medicine, 2002).

Hemp as a Therapeutic Agent

Rather than treating each system with a dedicated nutrient or substance group, studies point to the possibility that there are groups of plant compounds that have the ability to impact many ailments related to almost every body system: hemp compounds are a prime example.

Throughout history, hemp has been used as a therapy for issues from leprosy to earaches to the common headache. However, it took thousands of years before anyone found an answer to the question: how could one plant treat so many diverse ailments? The answer lies in a hitherto unknown system in the body that affects how almost every other system works: the ECS.
