Here's a roundup of five medical studies published this week that might give you new insights into your health, mind and body. Remember, correlation is not causation – so if a study finds a connection between two things, it doesn't mean that one causes the other.
Motörhead is one of the most hardcore rock ’n’ roll acts on Earth
That Motörhead has the reputation as one of the most hardcore rock’n’roll acts on earth may not surprise you. But finding evidence to support this claim in one of the major medical journals might.

"Eat breakfast!" nutrition experts have been telling us for decades. It revs your metabolism! It keeps you from overindulging at lunch! It helps you lose weight!
But a new study suggests the "most important meal of the day" may not be so important - at least for adults trying to lose weight.
Published Wednesday in the American Journal of Clinical Nutrition, the study found dieters who skipped breakfast lost just as much weight as dieters who ate breakfast regularly. The researchers concluded that while breakfast may have several health benefits, weight loss isn't one of them.

Editor's note: This blog was originally published in June 2013 when the research was presented at the American Diabetes Association Scientific Sessions in Chicago. The final study results were published Thursday in the journal Diabetologia.
You've probably heard that eating multiple small meals throughout the day is a good way to stave off hunger and keep your metabolism revved up while trying to lose weight. But a new study could change your diet strategy.
Eating two large meals early and skipping dinner may lead to more weight loss than eating six smaller meals throughout the day, the study suggests.
"Both experimental and human studies strongly support the positive effects of intermittent fasting," lead study author Dr. Hana Kahleova told CNN in an e-mail.

You know the saying, "An apple a day keeps the doctor away"? Turns out eating one apple isn't enough. A new study suggests people who eat up to seven servings of fruit and vegetables a day can cut their risk of premature death by 42% - and that vegetables may be more important than fruit to your overall health.
The study, conducted by scientists in the United Kingdom, was published online Monday in the Journal of Epidemiology and Community Health.

Eating a high-protein diet in middle age could increase your risk of diabetes and cancer, according to a study published this week in the journal Cell Metabolism. But don't stay away from meat for too long - the same study showed those over 65 need more protein to reduce their mortality risk.
Insulin-like growth factor 1, or IGF-1, is a protein in your body related to growth and development. Past studies have linked IGF-1 to age-related diseases, including cancer. Mice and humans with higher levels of IGF-1 often have a higher risk of developing these diseases.
Scientists believe protein intake plays a role in IGF-1 activity. Eating less protein, studies have shown, can lead to lower levels of IGF-1 in your body. So theoretically, protein consumption could be directly linked to disease incidence and death. FULL POST

Nearly a third of American adults have high blood pressure, also known as hypertension. Often called the "silent killer" because it provides few warning signs, hypertension increases a patient's risk for heart attack and stroke.
New research suggests eating a vegetarian diet could help combat this deadly disease.
A healthy blood pressure is 120/80 mm HG. Previous studies have shown that each increase of 20/10 mm Hg in that number doubles the patient's risk of cardiovascular disease. But lowering that top number just 5 mm HG can reduce your chances of dying from cardiovascular disease by about 7%. And eating more fruits and vegetables may be a good way to do that, according to the new study, published Monday in the scientific journal JAMA Internal Medicine. FULL POST

In recent years, sugar - more so than fat - has been receiving the bulk of the blame for our deteriorating health.
Most of us know we consume more sugar than we should. Let's be honest, it's hard not to.
The (new) bad news is that sugar does more damage to our bodies than we originally thought. It was once considered to be just another marker for an unhealthy diet and obesity. Now sugar is considered an independent risk factor for cardiovascular disease, as well as many other chronic diseases, according a study published Monday in JAMA Internal Medicine.

Eating nutritional foods is one of the best ways to reduce obesity. But following a healthy diet isn't always easy, especially for lower socioeconomic groups.
One of the biggest barriers to buying good food is the cost, many experts say. Now researchers at Harvard School of Public Health have put a dollar amount on the price of healthy eating. By reviewing 27 studies on the cost of healthy vs. unhealthy foods, they've estimated the daily cost of eating better. Their results are published in the British Medical Journal.
"Conventional wisdom has been that healthier foods cost more, but it's never been clear if that's actually true or exactly how much more healthier foods might cost," said lead study author Mayuree Rao. "We found that the healthiest diets cost about $1.50 more per day, and that's less than we might have expected."

Efforts to increase healthy habits in American teens may be making an impact, according to a new study. Adolescents are moving more, eating better and watching less TV than they used to, and researchers say obesity rates in this group may finally be stabilizing.
The study results come a little more than a month after the Centers for Disease Control and Prevention announced it was seeing signs of progress in the fight against childhood obesity, especially in low-income families.
In the new study, published Monday in the journal Pediatrics, researchers analyzed data from three sets of students in grades 6 to 10. One set was surveyed during the 2001-2002 school year, another set during the 2005-2006 school year and the third set from the 2009-2010 school year. Researchers asked the students about their daily physical activity, nutrition, breakfast consumption, TV habits, and height and weight. They then compared the answers across the three school years to identify trends in healthy - or unhealthy - behaviors.

There's a strong link between sugary drinks and obesity. Scientific studies have shown that adults who consume more sugar-sweetened beverages tend to have higher body mass indexes, or BMIs, than their water-drinking counterparts.
But until now, this association hadn't been closely examined in kids younger than 5.
The American Academy of Pediatrics recommends that young children avoid all sugar-sweetened beverages. A new study, published in the organization's journal Pediatrics, offers further evidence to support that recommendation.
