CSIC recovers part of the genome of 2 hunter-gatherer individuals from 7,000 years ago“The DNA data, which represent the 1.34% and the 0.5% of both individuals total genome, show that they are not directly connected to current populations of the Iberian Peninsula. Iberians from the Mesolithic Period were closer to current populations of northern Europe, who could have assimilated part of the genetic legacy of these hunters-gatherers.”

eat salt!

eat salt already! from scientific american:

“It’s Time to End the War on Salt”
“The zealous drive by politicians to limit our salt intake has little basis in science

This week a meta-analysis of seven studies involving a total of 6,250 subjects in the American Journal of Hypertension found no strong evidence that cutting salt intake reduces the risk for heart attacks, strokes or death in people with normal or high blood pressure. In May European researchers publishing in the Journal of the American Medical Association reported that the less sodium that study subjects excreted in their urine — an excellent measure of prior consumption — the greater their risk was of dying from heart disease. These findings call into question the common wisdom that excess salt is bad for you, but the evidence linking salt to heart disease has always been tenuous….

“Rather than create drastic salt policies based on conflicting data, Alderman and his colleague Hillel Cohen propose that the government sponsor a large, controlled clinical trial to see what happens to people who follow low-salt diets over time. Appel responds that such a trial ‘cannot and will not be done,’ in part because it would be so expensive. But unless we have clear data, evangelical antisalt campaigns are not just based on shaky science; they are ultimately unfair. ‘A great number of promises are being made to the public with regard to this enormous benefit and lives saved,’ Cohen says. But it is ‘based on wild extrapolations.‘”

Ancestry plays vital role in nutrition and disease, study shows“Dietary recommendations made by major health organizations are typically generalized to multiple populations, but are often based on available data from studies that represent one or two human populations. With regard to PUFAs, the American Heart Association currently recommends that Americans increase dietary PUFA levels to 5 to 10 percent of dietary energy. Studies like these suggest that such recommendations may not apply or be healthy for all populations.”

Dairy consumption does not elevate heart attack risk, study suggests

“They split the study population between two equal groups: 1,815 ‘cases’ who had non-fatal heart attacks and 1,815 comparable ‘controls’ who did not. The researchers looked not only at the subjects’ self-reported dairy intake, but also at measurements of dairy fat biomarkers, namely 15:0 and 17:0, in their bodies.

“What they found is that the dairy intake of people who had heart attacks was not statistically different than the intake of people who did not. After breaking people into quintiles, based on their dairy consumption amount, there was no significant linear relationship between consumption and heart risk, even among the most voracious consumers. The highest consumption quintile consumed an average of 593 grams of dairy foods a day.

“When the researchers controlled for such risk factors as smoking, waist-to-hip ratio, alcohol intake, and physical activity, the lack of a statistically significant association between dairy intake and heart attack risk remained. They also tracked and adjusted the data for levels of CLA and calcium and found they may have a protective effect. Protective effects lessened in the highest quintile, however.”

i drink milk and eat a fair amount of cheese. i’ve always figured that i come from a looooooooong line of lactose tolerant people so milk is prolly ok for me. and, goshd*rnit, i LUV milk! everything in moderation, tho (except for dark chocolate).

wtf medical establishm’t?

i’m gonna join the ranks of the one and dennis mangan in questioning wtf is with all the screwy dietary advice from the medical establishment?? eat lots of grains? hmmmmm. don’t eat too much animal fat? yeah, right. cholesterol is bad for you and causes vascular disease? pull the other one!

and now, starting to be de-bunked(?), don’t eat too much salt…

Fatal and Nonfatal Outcomes, Incidence of Hypertension, and Blood Pressure Changes in Relation to Urinary Sodium Excretion

“Conclusions – In this population-based cohort, systolic blood pressure, but not diastolic pressure, changes over time aligned with change in sodium excretion, but this association did not translate into a higher risk of hypertension or CVD complications. Lower sodium excretion was associated with higher CVD mortality.

yeah. you read that right. people who ate (or, at least, excreted) the LEAST amount of salt had a (slightly) higher death rate from heart disease. above-average salt intake did NOT increase blood pressure in this study.

i haven’t read the full article yet (will have to wait ’til after the weekend, i’m afraid), but wtf medical establishment? i’m sure working out all these dietary things is d*mn complicated, but quit giving advice without being as sure as you can be, already!

note that the study was done in denmark the flemish part of belgium, so maybe this applies only to danish flemish|germanic people. -?-
