The cover story on this week’s issue of TIME Magazine is making waves – and driving sales at the nation’s checkout counters. The article traces the recent history of nutrition science, specifically the 20th-century vogue for health messages about cutting consumption of saturated fat. It does a nice job laying out how those messages were seized upon by food marketers to create today’s grocery aisles thronged with “fat-free” and “low-fat” processed foods.
But ironically, in its effort to rehabilitate the reputation of saturated fat by showing how that food component has been isolated and demonized, the article effectively demonizes carbohydrates, blaming them for the same health conditions once widely linked with saturated fat.
It’s only the latest article in the popular press to do this. But while it makes a compelling read, singling out any one food or food component for blame oversimplifies a field of study marked by complexity and nuance.
As a cancer research and education organization, we should note that AICR’s expert reports and their updates have found no strong links between dietary fat itself –whether saturated or unsaturated – and cancer risk. Instead, it’s the fat we carry on our bodies that is strongly linked to increased risk for eight different cancers. Continue reading
If you’ve been trying to boost your heart health by eating a Mediterranean diet filled with olive oil, vegetables and nuts, and foregoing red and processed meat, a new report says you also may be lowering your risk for cancer and type 2 diabetes, all without losing weight.
A report of studies from PREDIMED, a large nutrition intervention trial, was published in the May issue of Advances in Nutrition. One study found that after almost 5 years, Mediterranean diet participants had 30% less cardiovascular disease than the control group. Another study found the Mediterranean diet groups had less type 2 diabetes, showed improvements in conditions of metabolic syndrome and had lower levels of markers for inflammation, all risk factors for cancer.
The Mediterranean diet, promoted as heart healthy, is rich in plant foods (such as vegetables, legumes, fruits and nuts), olive oil, moderate amounts of fish, yogurt, cheese, poultry and red wine, but little red and processed meats and sweets. In the PREDIMED study, researchers randomly assigned about 7500 participants to one of three groups: a Mediterranean diet (MeDiet) supplemented with olive oil, a MeDiet supplemented with nuts or they were instructed to follow a low fat diet. The PREDIMED study is a randomized, nutritional intervention trial conducted in Spain from 2003 to 2011. Continue reading
Eating healthy, exercising and being a healthy weight are among the behavior changes Americans can make to cut 20 to 40 percent of the five leading causes of US deaths, including cancer, according to a new report from the Centers from Disease Control and Prevention. For cancer, not smoking or drinking alcohol also play a key role in preventing deaths.
The report highlights how the same factors that reduce the risk of cancer also reduce the risk of other diseases. (We talk here about Eating to Prevent Heart Disease and Cancer the two leading causes of death.)
According to the report, the five leading causes of death in the United States are heart disease, cancer, chronic lower respiratory diseases, stroke, and unintentional injuries.
The CDC report focused on premature deaths. Together, the five leading causes of death accounted for almost two-thirds of all U.S. deaths in 2010. State by state, the report looked at mortality data from 2008-2010 of those who died before age 80. They then used the state with the lowest numbers of deaths as the benchmark to calculate the numbers of deaths from each cause that could be prevented in each state. Continue reading
