Is this actually a fact?

Neither White nor his defense team ever claimed that White's consumption of junk food had wrought psychological or physiological changes in White that caused him to act in way inconsistent with his "normal" behavior when he shot George Moscone and Harvey Milk. White's defense was that he had been suffering from a long-standing and untreated depression that diminished his capacity to distinguish right from wrong, and thus he was not capable of the premeditation required to support a charge of first degree murder. Dr. Martin Blinder was called as a witness by the defense to testify that the conversion of the previously health-conscious White to a diet of Twinkies and other junk foods was evidence of his depression.
