It’s been 16 years since I first stumbled upon a class of protective nutrients called phytoalexins, while I was researching the benefits of organic produce. [1] These unique compounds rarely appear in conventionally grown fruits and vegetables. In fact, they are only found at appreciable levels in organic produce. [2]

That is because plants only produce these powerful phytochemicals as a defensive “immune response”, when they are assaulted by bugs, bacteria, viruses, molds, or mildews. [3] Without some external threat stimulus, the plant has no need to produce them.

They are also referred to as secondary metabolites, because they are “organic compounds that are not directly involved in the normal growth, development, or reproduction of the plant”.

Biologists have named this defensive plant mechanism “Induced Systemic Resistance”, and this response has been recognized for more than 70 years. However, it is only recently that the health-promotional effects of these nutrients have been seriously considered. [4], [5]

Since the publication of the first (2009) HealthQuest Newsletter on this topic, there has been considerable additional research into the amazing properties of different phytoalexins. Although they are manufactured to protect the plant, or to help the plant recover from attack, they also provide enhanced antioxidant protection for the humans who consume them.

Numerous studies have shown that they also provide anti-inflammatory protection, unique anti-aging properties, and appear to inhibit the development of various forms of cancer. These interesting compounds have been identified in about 75 different plant species, including cruciferous vegetables, soybeans, garlic, tomatoes, rice, and certain types of beans. [6]

Seventy percent of shoppers, interviewed at Whole Foods, state that their #1 reason for purchasing organic products is to avoid exposure to pesticide residue. That is an extremely rational decision, even IF the vitamin levels were relatively similar to conventional (sprayed) counterparts.

But, now we know that these organically grown raw materials actually contain other unique phytonutrients that provide additional health benefits, far beyond those usually provided by our old friends, vitamins and minerals. I believe it is their presence in many Shaklee supplements that make then so remarkable.

Organic IS better!
