  • One of the early researchers in the genetic basis for all compulsive, addictive, impulsive behaviors is pharmacogeneticist Kenneth Blum, PhD, who did much of his seminal work at the University of Texas in San Antonio. When he moved from laboratory rodents to field research with people, he and his colleagues discovered malnourished brains with neurotransmitter deficiencies, and he began creating formulas of nutrients designed for opiate users, stimulant users, people craving comfort foods, and other unique populations defined by their neurotransmitter needs.

Following are a very few of Blum’s studies, which date back to the 1960s.

Kathleen DesMaisons, PhD

  • DesMaisons, K., Biochemical restoration as an intervention for multiple offense drunk driving. PhD dissertation, The Union Institute, Cincinnati, OH, 1996
  • A county program for multiple offender drunk drivers in San Mateo County, California, focused on diet and nutrition and enjoyed dramatic success. Participants added a nutritional component to their prescribed court-ordered treatment. they were taught to increase their awareness of what they were eating. They added protein, eliminated sugars and learned to eat enough, on time.
  • The Biochemical Restoration Program (BRP) was developed by Kathleen DesMaisons, PhD, a pioneering addiction specialist who recognized that alcoholics have a unique neurochemical make up that makes them highly sensitive to emotional pain. They are drawn at an early age to the drug effects of sugar. This solution gets transferred to alcohol. Treating the base neurochemistry affects treatment outcome in a significant way.
  • The DesMaisons program was a collaboration of the Criminal Justice Council and the Peninsula Community Foundation in San Mateo County. The Peninsula Community Foundation funded the program from 1994 to 1997 for $280,000. The courts sentenced offenders to participate. Adding the nutritional component to the standard treatment generated a 92% success rate.
  •  After tracking 64 people who had been arrested more than once for drunken driving: 32 who took the 4-month program with a follow-up 3 months later; and 32 “controls” who were sentenced to conventional treatment. After the program was over the researchers discovered that members of the control group were charged again, and for far more serious offenses, at four times the rate of program graduates. Only two participants in the nutrition program violated probation, while 13 members of the control group committed 32 violations.
  • DesMaisons later moved from Northern California to Albuquerque, New Mexico, and developed an international web based support program for sugar sensitive people using these same nutritional protocols.

Additional methods of brain repair, including cranial electrical stimulation, chiropractic, and acupuncture, have also been found effective:
