Eating to Live

The Meat-Disease Connection

Dr. Fuhrman’s position on the consumption of animal products is pretty clear, meat and diary dairy products leads to disease like heart disease and cancer. Even “healthy” choices like fish and chicken put you at risk. Take a look at this section from Eat to Live:
There is a relationship between animal protein and heart disease. For example, plasma apolioprotein B is positively associated with animal-protein intake and inversely associated (lowered) with vegetable-protein intake (e.g., legumes and greens). Apolioprotein B levels correlate strongly with coronary heart disease.1 Unknown to many is that animal proteins have a significant effect on raising cholesterol levels as well, while plant protein lowers it.2

Scientific studies provide evidence that many animal protein’s effect on blood cholesterol may be significant. This is one of the reasons those switching to a low fat-diet do no experience the cholesterol lowering they expect unless they also remove the low-fat animal products as well. Surprising to most people is that yes, even low-fat dairy and skinless white-meat chicken raise cholesterol. I see this regularly in my practice. Many individuals do not see the dramatic drop in cholesterol levels unless they go all the way by cutting all animal proteins from their diet.
According to Dr. Fuhrman white meats are no savior either:
Red met is not the only problem. The consumption of chicken and fish is also linked to colon cancer. A large recent study examined the eating habits of 32,000 adults for six years and then watched the incidence of cancer for these subjects over the next six years. Those who avoided red meat but at white meat regularly had a more than 300 percent increase in colon cancer incidence.3 The same study showed that eating beans, peas, or lentils, at least twice a week was associated with a 50 percent lower risk than never eating these foods.

Chicken has about the same amount of cholesterol as beef, and the production of those potent cancer-causing compounds called heterocyclic amines (HCAs) are even more concentrated in grilled chicken than in beef.4 Another recent study from New Zealand that investigated heterocyclic amines in meat, fish, and chicken found the greatest contributor of HCAs to cancer risk was chicken.5 Likewise, studies indicated that chicken is almost as dangerous as red meat for the heart. Regarding cholesterol, there is no advantage to eating lean white instead of lean red meat.6
The correlation between disease and consumption of animal products seems very clear. Even newer research warns of heighten stomach cancer risk associated with eating processed meats, like sausage, smoked ham, and bacon. Reuters reports:
A review of 15 studies showed the risk of developing stomach cancer rose by 15 to 38 percent if consumption of processed meats increased by 30 grams (1 ounce) per day, the Karolinska Institute said in a statement.
These foods possess cancer-causing additives outside of meat’s normal cancer-causing agents:
The institute said processed meats were often salted or smoked, or had nitrates added to them, in order to extend their shelf-life which could be connected to the increased risk of stomach cancer, the fourth most common type of cancer.
If this information spooked you, you might want to consider Dr. Fuhrman’s advice, “The best bet for overall health is significantly limit or eliminated all types of meat—red and white.”
