His recommendations are probably helpful for digestive distress. But he constantly emphasizes a low-fat diet, without addressing how this adversely affects the absorption of the fat soluble vitamins (A, D, E, K) and the long-term impact of not having enough of these vitamins. He doesn't address good fats (omega-3) vs. the bad ones (omega-6 and others). He demonizes fats, because they delay emptying of the stomach, but doesn't consider their role in providing a feeling of satiety so we don't get hungry so soon.
He uses the term "gas" and never differentiates between gas coming from the mouth (belching, originating in the stomach) and gas coming from the other end (flatulence, originating in the small intestine or colon).
He lists the many foods that relax the lower esophageal sphincter, which if not tightly closed allows the upward flow of stomach contents into the esophagus. But in the case of GERD and heartburn there must also be something in the stomach that creates enough pressure to propel the contents upward past the sphincter. He only considers excess stomach acid as the problem; in cases where avoiding acid foods doesn't do the trick, he suggests using an acid inhibitor, which in turn slows or prevents absorption of some minerals. But may doctors say the problem is too little stomach acid, especially in older people, which causes food to putrefy in the stomach and this is what creates the gas needed to propel the contents upward.
He offers suggestions for customizing the USDA's food pyramid based on your particular food sensitivities. The problem is that the USDA`s pyramid is nothing more than pandering to various food lobbying groups, not the biological needs of all humans. Would such a pyramid in Japan or China be so oriented toward grains instead of rice? There is really no need in humans for dairy products derived from milk intended to fatten calves.
He's not a fan of alternative approaches because they are not regulated by the FDA, and contents are not consistent. I see that as a plus, because FDA-approved drugs kill over 106,000 people in the US every year, even when properly administered exactly as the doctor prescribed. (JAMA, July 26, 2000. [...])
He offers good tips to motivate people to exercise and manage the stresses that contribute to digestive problems.
