It’s not that confusing. Diet and exercise matter for cancer prevention.

By Posted on 3 Comments on It’s not that confusing. Diet and exercise matter for cancer prevention.

Not smoking will lower your risk of many cancers. Getting vaccinated will lower your risk of certain cancers. And eating a healthy diet along with exercising regularly will also lower your risk of certain cancers.

It’s not that confusing.

If you read a widely shared New York Times piece going around this week, you would think that you shouldn’t trust any evidence when it comes to diet and exercise and cancer risk. That’s not true.

It’s not a single study, or even several. It’s looking at the entire body of research, systematically and thoroughly – what we do here at AICR – and what that shows is:

The foods you eat will lower your risk because staying a healthy weight is so important for cancer prevention.

-Getting at least 30 minutes of moderate activity a day reduces the risk of breast, endometrial and colorectal cancers. Emerging research suggests possibly more.

    Study: Prepackaged Meals May Spur More Weight Loss

    By Posted on 3 Comments on Study: Prepackaged Meals May Spur More Weight Loss

    With many Americans trying to get to or stay a healthy weight, it’s important to find evidence-based strategies that help people lose weight not only in the short term, but that are also realistic to follow long-term to keep the weight off. That’s important for cancer prevention, because with AICR’s latest report on stomach cancer, we now know that obesity is linked to increased risk for 11 cancers, including colorectal, endometrial and kidney.

    A new study published in Obesity last week, found that in a 12-week weight loss program, people randomized to receive portion-controlled and prepackaged foods lost more weight compared to those who selected their own diet. Of the 183 participants, all overweight or obese, 139 received portion controlled, prepackaged lunch and dinner Lean Cuisine frozen entrees, and 45 selected their own foods based on the diet prescription given to both groups.

    Both groups successfully lost weight, but the group receiving preportioned foods lost more than 8% (18 lbs on average ) of their weight compared to 6% (13 lbs on average) weight loss in the control group. The prepackaged meals group also had lower LDL (bad) cholesterol and triglycerides than the control group.

      Now, on World Cancer Day, We Already Have the Knowledge, Tools to Prevent So Many Cancers

      In his State of the Union address, President Obama announced a “moonshot” program to fight cancer. In charge of that program, Vice President Biden has met with oncologists, scientists, and other leaders in the cancer field, and stated that, “We’re trying to get to a quantum leap on the path to a cure”

      Much of the focus has been on Big Data, and on sharing science across institutions, in the effort to quickly move results from the lab to the public. In a nation where approximately four in ten people can expect to be diagnosed with invasive cancer in their lifetimes, we need big efforts to fight this disease.

      Today, World Cancer Day, is a time to raise awareness of prevention: Cancer prevention needs to be a part of the renewed push against cancer.

      Focusing only on the cure is like trying to douse a forest fire on one front while someone is lighting matches on another. The good news is that we already have the knowledge and tools here on earth to prevent a large proportion of cancers from developing, without reaching for the moon.

      WCD adAvoidance of known carcinogens (including tobacco, excess radiation, sun and tanning), and use of vaccines for human papilloma and hepatitis B viruses, can prevent a wide range of cancers such as lung, skin, liver, cervix, mouth and throat. Screening and removal of premalignant lesions can prevent several cancers including those of the skin, colon, and cervix. Medications have been shown in clinical trials to prevent breast or prostate cancers in persons at high risk for those cancers.
