Green tea isn’t always green
From P.D. Mangan’s new book “Best Supplements for Men“:
Green tea, which is commonly drunk in China and Japan, is associated with lower rates of cancer, about 30% lower in those who drank the highest amounts of green tea compared to the lowest. Deaths from cardiovascular disease were about 25% lower in the highest consumption group versus the lowest. This is of course epidemiological evidence, meaning that it can’t show whether green tea actually prevented disease, or that there’s some other connection such as that heather people drank more green tea.
Laboratory and other evidence, however, provides some good reasons to think that green tea is the real deal when it comes to sides prevention.
A recent study of the elderly in Singapore found tea consumption linked to much lower risk of neurocognitive decline in women and carriers of the “dementia gene” APOE ε4.
P.D. suggests that the health-promoting dose of tea is 3 to 5 cups a day, and black tea may be just as good as green.

Death in a bottle?
Monica is a smart and media-savvy nutritionist who brought me on board as a blogger at NutritionData many years ago. Click the link below for her surprising conclusion on calcium supplementation.
“The National Osteoporosis Foundation published a new report this week, insisting that calcium supplements are safe for your heart. Two weeks ago, Johns Hopkins cardiologist Erin Michos published a paper saying the opposite.
She claims that the NOF review (which was funded by a pharmaceutical company that makes calcium supplements) omitted certain studies (such as the ones she included in her own review) that might have changed the conclusion.
These are just the latest two volleys in a five-year-long tennis match between experts on whether you should or shouldn’t take calcium supplements. And you thought politics was divisive.”

This won’t surprise you if you’ve been reading this blog for a while:
“Heart disease is the leading cause of death for both men and women in the United States, killing around 610,000 people annually. Heart attack affects around 735,000 Americans each year, while around 800,000 people are affected by stroke.
Adopting a healthy diet is considered key for reducing the risk of CVD, and numerous studies have suggested the Mediterranean diet fits the bill.
A study published in the European Heart Journal earlier this year, for example, found older adults who adhered to the Mediterranean diet were at lower risk of heart attack, stroke, and cardiovascular death than those who followed a Western diet.”

That’s a dumbbell in her right hand. I work-out with those myself.
I don’t have access to the full scientific report, but I’ve posted part of the abstract below.
The biggest problem with the study at hand is that physical activity apparently was surveyed only at the start of this 14-year study. Results would be much more robust if activity was surveyed every year or two. My overall activity level seems to change every two or three years. How about you?
“Compared to women who reported no strength training, women engaging in any strength training experienced a reduced rate of type 2 diabetes of 30% when controlling for time spent in other activities and other confounders. A risk reduction of 17% was observed for cardiovascular disease among women engaging in strength training. Participation in both strength training and aerobic activity was associated with additional risk reductions for both type 2 diabetes and cardiovascular disease compared to participation in aerobic activity only.
CONCLUSIONS: These data support the inclusion of muscle-strengthening exercises in physical activity regimens for reduced risk of type 2 diabetes and cardiovascular disease, independent of aerobic exercise. Further research is needed to determine the optimum dose and intensity of muscle-strengthening exercises.”

Dead whole fish aren’t very appealing to many folks
Heart disease is still the #1 killer in the U.S., followed by cancer and chronic lower respiratory tract disease. “Heart disease” is a broad category; the primary killer is heart attacks.
Eating fish regularly seems to reduce your risk of heart attack. I favor the cold-water fatty fish like salmon, trout, herring, and sardines.
I quote the NYT:
“Numerous studies have found that people who eat fish on a regular basis are less likely to die of a heart attack than those who don’t eat it or eat it less than once a month, and a 2006 Harvard review concluded that eating one to two servings of fish rich in omega-3s every week cut the risk of dying of a heart attack by one-third.”

The Telegraph has the details:
“Some 20,000 lives could be saved each year if Britons switched to a Mediterranean diet, according to a new study.
The Medical Research Council (MRC) and Cambridge University followed nearly 24,000 people in the UK for up to 17 years to see how their diet affected the health of their heart.
They discovered that people who followed a diet high in fruits, vegetables, whole grains, nuts, fish and olive oil lowered their risk of cardiovascular disease by up to 16 per cent. The researchers estimate that 12.5 per cent of cardiovascular deaths, such as heart attacks and strokes, could be prevented if everyone switched to the Mediterranean diet. There are around 160,000 heart deaths each year so 20,000 deaths could be avoided just by eating more healthy foods.”
