KCAHF was founded in 1996 as a private nonprofit, voluntary health agency that focused upon health misinformation, fraud, and quackery as public health problems. Its positions were based upon the principles of science that underlie consumer protection law.

KCAHF advocated:

(a) adequate disclosure in labeling and other warranties to enable consumers to make truly informed choices; 

(b) pre-marketing proof of safety and effectiveness for products and services claimed to prevent, alleviate, or cure any health problem; and, 

(c) accountability for those who violate the law.

The organization dissolved in 2017. This website continues in order to promote science-based medicine and the positions advocated by KCAHF.


Nancy Tullis, R.D., died on July 20, 2013.  Nancy was a founding member of KCAHF and was the driving force behind the group for many years.  At various times she served as President, Secretary, and Treasurer.  From her published obituary:

"As President of the Louisville Dietetic Association, she formed Dial-a-Dietitian, a service for the public, which continued for five years. She was on the Board of the Kentucky Dietetic Association for more than ten years, and was chairman of the legislative committee which achieved passage of the certification of dietitians and nutritionists in the Kentucky legislature. When licensure was achieved she served on the first Board of Licensure for Dietitians and Nutritionists by appointment of Governor Brereton Jones.

"Mrs. Tullis volunteered in the office of two Kentucky Attorneys General in planning and coordinating two Health Fraud Conferences for health professionals across the state. She was a founding member of the not-profit Kentucky Council Against Health Fraud, which continues in existence. She was a five-year board member of the National Council Against Health Fraud."
