Episode 30 - 5 things Harvard says make you live longer? Why you should floss your teeth everyday, 1 on 1 with Dwayne Update, movement, and other health and wellness topics
On this episode, we discuss 5 things that a 2018 Harvard study said doing consistently results in people living 10-14 years longer (exercise, eat well, maintain a healthy weight, don’t drink alcohol excessively, and don’t smoke), we get an update from Dwayne on his training and following the JVB program, and we discuss a few other health studies, sleep, movement, and why you should floss your teeth everyday!
Harvard 2018 study - Healthy lifestyle: 5 keys to a longer life
The researchers looked at data on diet, physical activity, body weight, smoking, and alcohol consumption that had been collected from regularly administered, validated questionnaires.
What is a healthy lifestyle, exactly?
These five areas were chosen because prior studies have shown them to have a large impact on risk of premature death. Here is how these healthy habits were defined and measured:
1. Healthy diet, which was calculated and rated based on the reported intake of healthy foods like vegetables, fruits, nuts, whole grains, healthy fats, and omega-3 fatty acids, and unhealthy foods like red and processed meats, sugar-sweetened beverages, trans fat, and sodium.
2. Healthy physical activity level, which was measured as at least 30 minutes per day of moderate to vigorous activity daily.
3. Healthy body weight, defined as a normal body mass index (BMI), which is between 18.5 and 24.9.
4. Smoking, well, there is no healthy amount of smoking. “Healthy” here meant never having smoked.
5. Moderate alcohol intake, which was measured as between 5 and 15 grams per day for women, and 5 to 30 grams per day for men. Generally, one drink contains about 14 grams of pure alcohol. That’s 12 ounces of regular beer, 5 ounces of wine, or 1.5 ounces of distilled spirits.
Researchers also looked at data on age, ethnicity, and medication use, as well as comparison data from the National Health and Nutrition Examination Surveys and the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research.
Does a healthy lifestyle make a difference?
As it turns out, healthy habits make a big difference. According to this analysis, people who met criteria for all five habits enjoyed significantly, impressively longer lives than those who had none: 14 years for women and 12 years for men (if they had these habits at age 50). People who had none of these habits were far more likely to die prematurely from cancer or cardiovascular disease.
Study investigators also calculated life expectancy by how many of these five healthy habits people had. Just one healthy habit (and it didn’t matter which one) … just one… extended life expectancy by two years in men and women. Not surprisingly, the more healthy habits people had, the longer their lifespan. This is one of those situations where I wish I could reprint their graphs for you, because they’re so cool. (But if you’re very curious, the article is available online, and the graphs are on page 7. Check out Graph B, “Estimated life expectancy at age 50 according to the number of low-risk factors.”)
