Roger Williams, PhD. discoverer of pantothenic acid (vitamin B5) and founder and director of the Clayton Foundation Biochemical Institute at the University of Texas, was a visionary in the understanding of biochemical uniqueness. Dr. Williams' timeless classic Biochemical Individuality, acknowledges the unique biochemical variations among individuals and how these differences relate to their distinct nutritional needs for optimal health and disease prevention.
Nutritional Individuality: Nutritional needs are as unique as fingerprints; what makes a good diet for one person can be seriously deficient for another... Roger Williams
Biochemical Individuality: We are all genetically and biochemically unique. For optimal function, we each have unique nutritional needs and specific environmental requirements. Bad genes do not cause disease by themselves - nutrition and environment can alter the outcome.
Biochemical Individuality explains why: the harmful amino acid homocysteine may or may not cause heart disease; low fat diets cause some people to gain weight. One person needs higher levels of nutrient then another to be healthy.
