Mediterranean diet may lower risk of brain damage
Following on from studies showing that a Mediterranean-like diet may be associated with a lower risk of Alzheimer's disease and may lengthen survival in people with Alzheimer's, a six-year study of 712 New Yorkers has revealed that those who were most closely following a Mediterranean-like diet were 36% less likely to have brain infarcts (small areas of dead tissue linked to thinking problems), compared to those who were least following the diet. Those moderately following the diet were 21% less likely to have brain damage.

Meal-time affects cholesterol in liver
Submitted by Fiona McPherson

A mouse study suggests that merely changing meal times could have a significant effect on the levels of triglycerides in the liver. Levels of triglycerides followed a circadian rhythm, with levels peaking about eight hours after sunrise (note that mice are nocturnal). Mice generally eat 20% of their food during the day, and 80% at night. Mice lacking a functional body clock eat constantly during the day. When normal mice were given the same amount of food, but had to eat it only at night, there was a quick and dramatic 50% decrease in overall liver TAG levels.
Dietary guidelines for choline may be insufficient

A study involving healthy men and women fed a baseline diet containing 550 mg choline/day (the adequate intake level set by the Institute of Medicine) for 10 days, then put on a low choline diet (50 mg choline/day) for up to 42 days, has found that the "right" amount of choline depends on many factors, including gender, age, and ethnicity.

Meat and cheese may be as bad for you as smoking
Submitted by Fiona McPherson
on
A large long-running study has found that eating a diet rich in animal proteins during middle age makes you four times more likely to die of cancer than a low-protein diet (a mortality risk factor comparable to smoking), 74% more likely to die of any cause within the 20-year study period, and five times more likely to die of diabetes. Even those eating a moderate amount of protein had much higher levels of mortality risk.
However, a high or moderate protein diet is helpful for those over 65, when levels of the growth hormone IGF-I drop off dramatically.

Cholesterol levels linked to amyloid plaques in brain

A study involving 74 older adults (70+), of whom 3 had mild dementia, 33 were cognitively normal and 38 had mild cognitive impairment, has found that high levels of "good" cholesterol and low levels of "bad" cholesterol correlated with lower levels of the amyloid-beta plaques in the brain (a hallmark of Alzheimer's disease).

Higher levels of copper in amyloid plaques associated with degree of neurodegeneration
Submitted by Fiona McPherson
on
Following on from the evidence that Alzheimer’s brains show higher levels of metals such as iron, copper, and zinc, a mouse study has found that amyloid plaques in Alzheimer’s-like brains with significant neurodegeneration have about 25% more copper than those with little neurodegeneration. This is consistent with a human study showing very high levels of copper in Alzheimer’s plaques.
Iron, though doubled in Alzheimer’s brains compared to controls, was not significantly different as a function of neurodegeneration, and zinc showed very little difference.
