Dietary Protein, Not Sugar, Promotes the Growth of Cancer

Some researchers in Bel­gium just did an inter­est­ing study about how yeast cells use sug­ar. This study helps to explain why yeast cells mul­ti­ply rapid­ly when they have plen­ty of sug­ar. The results of their study could also explain why some can­cer cells also mul­ti­ply rapid­ly. How­ev­er, this study does not mean that sug­ars and starch­es in the diet are a prob­lem. In fact, high-car­bo­hy­drate diets actu­al­ly help to pro­tect against many can­cers. Rather, the study explains why can­cer cells with abnor­mal sug­ar metab­o­lism might behave like yeast cells.

Many Cancer Cells Have an Abnormal Metabolism

Since the 1920s, sci­en­tists have known that many can­cer cells don’t use oxy­gen to burn sug­ar, even when plen­ty of oxy­gen is avail­able. By the 1950s, it was clear that tumors that are most like­ly to use anaer­o­bic (no-oxy­gen) metab­o­lism tend to be the most aggres­sive. Unfor­tu­nate­ly, the reporters who have been cov­er­ing this study for the pop­u­lar press do not under­stand what the study is about or what its results real­ly mean.

Many of the reporters have false­ly con­clud­ed that the study shows that some­thing in sug­ar is some­how caus­ing can­cer. As a result, they are urg­ing peo­ple to avoid eat­ing car­bo­hy­drates. But if peo­ple fol­low that advice, they would actu­al­ly increase their risk of ear­ly death. If peo­ple avoid car­bo­hy­drates, they will end up eat­ing more fat and more ani­mal pro­tein. High-fat diets increase your risk of heart attacks. Also, diets that are high in ani­mal pro­tein increase your risk of dying of can­cer.

Jane Brody’s Misleading Attack on What the Health

New York Times colum­nist Jane Brody wrote a sil­ly attack on the doc­u­men­tary What the Health. Germany’s Iron Chan­cel­lor Otto von Bis­mar­ck sup­pos­ed­ly once quipped, “Nev­er believe any­thing in pol­i­tics until it has been offi­cial­ly denied.” Since the New York Times is regard­ed as the “News­pa­per of Record” in the Unit­ed States, we could amend this say­ing to “Nev­er believe any­thing in Amer­i­can pol­i­tics until it has been offi­cial­ly denied in the New York Times.”
