No-Fenol™️ was developed by Dr. Devin Houston, CEO of Houston Enzymes, in response to requests for a product that would support the digestion of fruits and vegetables, without the problems thought to be associated with polyphenolic compounds. Responses from customers indicate that for many, No-Fenol does allow the addition of these foods to the diet without complications.

All plants contain some degree of polyphenolic compounds (sometimes called “phenols”). The polyphenol structure itself is found everywhere in nature, and is essential to many of life’s processes.

Current thinking is that some people have difficulty in the processing of polyphenolic compounds.

While the reasons are not well defined, it is thought that perhaps the polyphenols in foods become “trapped” in some part of a metabolic cycle, presumbably involved with various detoxification pathways.

The research literature indicates that some polyphenols are modified by the addition of carbohydrate groups to their structures, which may inhibit their crossing into cells and being metabolized.

The current hypothesis for why No-Fenol may help is through the ability of the enzymes in this product to remove the carbohydrate groups from the polyphenols, thus allowing normal processing by the detoxification pathways.

There is no evidence that No-Fenol directly modifies polyphenolic structures. Rather, the success of No-Fenol in allowing the addition of polyphenolic foods back into the diet of some may result in a re-evaluation of the basis of the polyphenol “problem”.

The enzyme xylanase is the major component of No-Fenol, and is an enzyme used to breakdown the structural components of plant cell walls, which are primarily very complex carbohydrates. Xylanase is used in the juice industry to extract more juice from fruit pulp fibers.

At least one reference indicates that polyphenolic compounds are actually increased with use of xylanase. Based on this reference and the fact that No-Fenol has allowed “phenol-sensitive” individuals to ingest polyphenolic foods, Houston Enzymes now believes that the polyphenol issue is much more complex than previously thought, and may not be due so much to the presence of phenols as to the specific structure of these polyphenols.†

Foods rich in polyphenols include:

  • brightly colored fruits
  • brightly colored vegetables
  • red wine
  • coffee
  • black and green teas
  • spices
  • dark chocolate
