The Actual Benefit of Diet vs. Drugs

One of the reasons people may undervalue diet and lifestyle changes is an overconfidence in the ability of pills and procedures to prevent disease. For example, people tend to wildly overestimate the power of things like mammograms and colonoscopies to prevent deaths from breast and bowel cancer, or the power of drugs like Fosamax to prevent hip fractures, or the power of cholesterol drugs to prevent fatal heart attacks. Patients believe statin drugs like Lipitor are about 100 times more effective than they actually are in preventing heart attacks. Most people wouldn’t take multiple blood pressure medications if they knew the truth.
For most people, the chance of benefit is normally less than 5 percent over five years for cholesterol, blood pressure and blood thinning drugs. Patients don’t want to take drugs unless they have at least a one in five chance—even those who just had a heart attack. It’s no wonder that doctors seldom share these figures. Therefore, informing patients of the percentage chance of benefit from preventive drug strategies will likely substantially reduce the uptake of such drugs.
For the individual, this is unlikely to be detrimental; after all, there’s a 95 percent chance it won’t do anything for them. But for the population at large, it would make a difference, so doctors and drug companies oversell the benefits by conveniently not mentioning how tiny they actually are, knowing most patients wouldn’t take them if doctors divulged the truth. To practice non-lifestyle medicine is to practice deceptive medicine. 
The best that cholesterol-lowering statin drugs appear to do is an absolute risk reduction of 3.1 percent over six years. If Dr. Esselstyn’s work can be replicated in a randomized, controlled trial, then a whole foods plant-based diet will have been shown to work twenty times better, an absolute risk reduction of 60 percent after less than four years. In Esselstyn’s study, 99.4 percent of patients that stuck with the diet avoided major cardiac events, such as death from heart attack.
When we have to decide whether we want to go diet versus drugs, we’re not making a choice between eating healthy to prevent a heart attack or taking a pill to prevent a heart attack. Because in 97 percent of cases in the near-term, pills don’t do anything. We’re risking side effects for nothing, whereas if we treat the underlying root cause of the disease by eating a healthy, cholesterol-free diet, we may even reverse the progression of the disease.
If we stop eating an artery-clogging diet, our bodies can start dissolving that plaque away, opening up arteries in some cases without drugs or surgery. A healthy whole food plant-based diet by itself may work 20 times better than drugs to combat our #1 killer.
Now that’s something doctors may want to tell their patients.
