HealthTalk: Do high-fat diets lead to cancer?

By Posted on Leave a comment on HealthTalk: Do high-fat diets lead to cancer?

Do high-fat diets lead to cancer? Not necessarily. That’s a common concern though: The most recent AICR awareness survey shows that more than 4 in 10 people think that high-fat diets can be a cause of cancer. However, whether your diet is higher or lower in fat, it’s your overall eating choices that matter to reduce your risk of cancer.

Early research on diet and cancer risk did suggest a link to fat consumption, since countries with low fat intake (for example, Japan) had lower rates of cancer than countries (like the U.S.) with higher-fat diets. After further study, when scientists followed people over time and adjusted for other eating and lifestyle choices, differences in cancer risk no longer seemed related to fat consumption.

So what does today’s best science tell us about dietary fat in the big picture of healthy eating choices to help prevent cancer? Read more… “HealthTalk: Do high-fat diets lead to cancer?”

    New study – higher weight links to earlier death

    By Posted on 1 Comment on New study – higher weight links to earlier death

    There’s been some controversy about whether being overweight, but not obese, might actually link to a longer life. A few years ago a major study suggested that paradox. We wrote about it here.

    For lower cancer risk, healthy weight is key. AICR’s reports find that overweight and obesity increase risk for 11 cancers, including colorectal and postmenopausal breast.

    In this new analysis on weight and mortality, researchers used a person’s highest weight during the study and found that those who were overweight or obese had increased risk for early death. The data comes from 225,000 participants in the Nurses Health Studies (NHS I and II) and the Health Professionals Follow-Up Study (HPFS). It was published last week in the Annals of Internal Medicine.

      Bone-derived Hormone Regulates Appetite in Mice

      We often think of bones as static, lifeless structures, but scientists are learning that bones are far more dynamic than once believed and play important roles in immunity, kidney health, and metabolism. Now research published in Nature has identified a hormone produced by bone cells that helps regulate appetite in mice, a finding that adds to the understanding of weight management and potentially cancer risk.

      Obesity increases risk of many types of cancer.

      Scientists have long known that fat cells produce a hormone called lipocalin-2, but the researchers in this study discovered that bone-forming cells produce as much as 10 times more lipocalin-2 than fat cells. Read more… “Bone-derived Hormone Regulates Appetite in Mice”
