We have found the holy grail and it is chocolate. Lo, “Eating 100 g of chocolate daily linked to lowered heart disease and stroke risk”. One hundred grams a day! That’s about a quarter of the average adult woman’s total daily calorie intake. (About one sixth for a man).
So much for the 99% certain consensus that chocolate was junk food.
Eating up to 100 g of chocolate every day is linked to lowered heart disease and stroke risk. The calculations showed that compared with those who ate no chocolate higher intake was linked to an 11% lower risk of cardiovascular disease and a 25% lower risk of associated death.
They base their findings on almost 21,000 adults taking part in the EPIC-Norfolk study…
Around one in five (20%) participants said they did not eat any chocolate, but among the others, daily consumption averaged 7 g, with some eating up to 100 g.
Chocolate was associated with younger age… (we want some of that, right?)
Higher levels of consumption were associated with younger age and lower weight (BMI), waist: hip ratio, systolic blood pressure, inflammatory proteins, diabetes and more regular [...]
Researchers were sure fatter people would get more dementia, so they studied two million middle-aged people for nearly a decade but were “baffled to find the exact opposite. Their sample included 45,000 cases of dementia and the obese were 30 per cent less likely to be diagnosed with it.
This contradicts previous studies and was not at all what the researchers expected, so they analyzed the data every which way they could think of but can’t explain the results. Need I say “experts” and “consensuses”?
Scientists at the London School of Hygiene and Tropical Medicine said they were baffled by the results as previous studies have shown that being overweight raises the risk. –Telegraph
Risk factors such as alcohol and smoking made little difference to the results, published in The Lancet Diabetes and Endocrinology. — Mirror
Dr Qizilbash said the findings held despite attempts to adjust for other causes of dementia and the tendency of obese people to die earlier. “We did a lot of analysis to see if we could explain it but just seems to persist. We couldn’t get rid of it so we’re left with this apparent protective effect,” he said. [...]
I like to keep an eye on research on keeping our brains intact (even if it’s not far past the leeches-and-arsenic stage). Here is a tiny trial showing a bit of promise. After years of testing drugs on Alzheimer plaques without much luck, as far as I can tell, this study had the radical idea of doing a bit of everything that had seemed to delay Alzheimers — like exercise, dumping the carbs, mini-fasts, fish oil, meditation and things like that. Unlike the drug trials, this one actually seemed to work and surprisingly for as many as 9 out of 10 patients (there were only ten patients, that’s not a ratio). It’s quite neat that it did work. It has lots of potential (though not much in the way of profits for big-pharma). However it was only six months long. It may not be slowing the plaques, but then if it restores functional memory, that’s rather the point (though I worry those plaques are coming back later).
Nonetheless, if you like the idea of saving your brain. Worth reading the list below, just so you know and pass it on to those with an interest. Anything that helps, especially when [...]
Remember the experts who said we should drink skim milk? A new large study suggests that full fat milk is healthier. So much for that consensus about saturated fat. There have been signs things were amiss. A few studies recently have shown that milk, yogurt and cheese consumption were associated with a lower incidence of Diabetes Type 2. Dairy didn’t seem to make the heart attacks more likely either. Hmm. So this new study of 26,000 women looked at high fat versus low fat dairy products. Over 14 years the highest consumption (which is 8, crikey, portions of full fat dairy a day) is associated with … a 23% reduction in risk compared to the low fat dairy consumers. Time to eat more Brie? Maybe, maybe not.
I won’t be taking up 8 portions of full fat dairy myself – the 23% figure is not seismic, is based on a modeled estimate (so is open to debate). I suspect it’s not the fat content that is the most important thing here, but something else entirely. The “displacement effect” confounds this sort of study. It might not be that dairy fat is so helpful, just that it is less bad that [...]
Something different to discuss – for the medical-revolution cynics among us. Cells from a human triple-negative breast cancer were implanted in mice under their mammary fat pads. Triple negative breast cancer is a nastier form of breast cancer which is harder to treat because these cells don’t respond to the usual anti-estrogenic drugs.
The mice were then allowed to eat only 70% as many calories as they would normally freely choose to eat. This is a particularly interesting study because it shows that calorie restriction inhibited the expression of certain micro RNAs even from foreign (non mouse) implanted breast cancer cells, and this apparently kept the cancer from spreading. Notably fatalities from cancers don’t usually come from the initial solid tumor but from the metastasized version, so this is potentially very useful.
The mechanism involves strengthening the matrix around the cancer cells. When these cancer cells have metastasized they produce more of these particular micro RNA’s which in turn appear to stop production of proteins that strengthen the extracellular matrix. In other words, the cancer cells probably use the micro RNA’s to degrade the cellular matrix around them in order to spread. The implications of this are both that the [...]
Disaster Disaster! Driving a car in 2014 could one day cause 2 billion people to suffer from zinc and iron deficiencies leaving them anaemic and prone to infection, and causing a loss of 63 million life-years annually. This is brought to you from the Annals of Hyped-Science (formerly known as Nature). A sad day indeed.
It’s true that carbon dioxide is plant fertilizer and increases plant yields, so future crops, grown in a CO2 rich world, may not have exactly the same nutrient profile. Presumably future plants will have slightly more useless starchy carbohydrate. It is a kind of dilution effect at work, where plants keep absorbing the same amount of minerals, but spread them out among more carbohydrate.
Before we hit the panic button, lets look the numbers. The new Myers et al study reports that zinc and iron content of rice may fall by, wait for it, five percent. In wheat the iron content could fall by as much as 10%. But no one who has a choice, eats grains like rice or wheat for their iron and zinc content, since both these are poor sources of both. We’re talking about low grade bulk filler food.
Assuming the reduction [...]
