what is the optimal level of vitamin D in your blood? It turns out that people with a vitamin D level of about 81 livethe longest. Mortality rate increases as your vitamin D level gets above 100 or less than 40. About 85% of people with body mass index over 30 have a low vitamin D level (less than 30). Does taking vitamin D supplements make you livelonger? Not as clear.
People who have diabetes have a 62% higher mortality rate. If you are getting diabetes, it is best to aggressively change your lifestyle and not get it. "Intake of fruit, legumes, nuts, seeds, pasta, poultry and vegetable oil was related to a lower mortality risk, and intake of butter and margarine was related to an increased mortality risk"
Sitting at work for more than 10 hours per day had a harmful effect on women, increasing their mortality rate by 19% relative to those who sat less than 5 hours. Sitting watching over 5 hours per day of TV was associated with 19% higher rate of cardiac death in men and 32% higher in women, relative to abstainers.
Not many things reliably help people lose weight. This study (like many others) found that adherence to a weight loss program and self-monitoring of weight both make a big difference. If you want to lose weight, probably best to eagerly participate in a program, and weigh yourself every day.
Many people have not heard of "The Metabolic Syndrome". It has been all the rage in recent years in primary care. It goes by a number of different names: insulin resistance, glucose intolerance, pre-diabetes. It is thought to be both a risk factor for heart disease and a warning sign that you are about to get diabetes. How can you tell if you have it? Supposedly you have it if you have 3 or more of the following: * waist circumference greater than 40 inches in men or 35 in women, * serum triglycerides > 150, * HDL ("good") cholesterol l< 40 in men or < 50 in women, * blood pressure > 130/85, * fasting blood sugar > 100
It has long been known that people of more privileged socioeconomic background live longer on average. For example, the more years of school you have had and the more stable your employment, the longer you live. This study investigated why. They found that most (70%) of the benefit of education on preventing heart disease is because people with more education tend to have better diets and exercise habits. So education causes better eating and exercise which causes less heart disease which causes less death. That's most of the story anyway.
Those who drank soymilk daily had 70% lower rate of prostate cancer than abstainers. men with prostate cancer who ate more fruits and veggies reduced their risk of progression by 59% relative to those who are the least. Green tea reduced the rate of widespread prostate cancer. In short, eating a plant-based diet and avoiding the usual suspects (meat, dairy, and eggs) is our best medicine against prostate cancer. Far tastier than PSA tests and digital rectal exams (yuck).
In emergency room circles, they call them donorcycles, because that's where organ donations come from. For every mile ridden on a motorcycle, the rider has 35 times the risk of dying relative to riding in a car. But if you in that demographic of safety-conscious motorcycle riders, hear this: Riders who wear Full Face Helmets enjoy about 1/5 the risk of having a facial fracture.
Sodium alginate oral suspension was as affective as omeprazole (Prilosec), for regular-old espohageal reflux (GERD), without ulcers or other erosions. Omeprazole and other proton-pump inhibitors (PPIs) are know to increase risk of some infections and of bone thinning.
