Mozambican Grass Seed Consumption During the Middle Stone Age

The role of starchy plants in early hominin diets and when the culinary processing of starches began have been difficult to track archaeologically. Seed collecting is conventionally perceived to have been an irrelevant activity among the Pleistocene foragers of southern Africa, on the grounds of both technological difficulty in the processing of grains and the belief that roots, fruits, and nuts, not cereals, were the basis for subsistence for the past 100,000 years and further back in time. A large assemblage of starch granules has been retrieved from the surfaces of Middle Stone Age stone tools from Mozambique, showing that early Homo sapiens relied on grass seeds starting at least 105,000 years ago, including those of sorghum grasses.
Reports that vitamins C and E may blunt the positive effects of exercise are misleading, according to an antioxidant expert.
German researchers have reported that antioxidant vitamins C and E may blunt the positive effects of exercise, with respect to insulin sensitivity. Findings were published in the Proceedings of the National Academy of Sciences.
Reacting to the study , Alexander Schauss, PhD, from AIBMR Life Sciences, a nutraceutical products consultancy, told NutraIngredients.com that the title of the study (Antioxidants prevent health-promoting effects of physical exercise in humans) was misleading.
"The primary objective of this study was to study the effect of a 4-week intensive 5-days a week exercise program on insulin sensitivity. Yet the title of the paper leads one to believe otherwise," he said.
"This is a small gender-biased study of 40 male subjects, 25 to 35 years of age. When I read through the study for the first time I had to wonder how could the authors have come up with such a title for their paper?" he asked.
August of this year, the BBC reported that the British Advertising Standards Authority attacked a vegetarian organization for making "alarmist" and "unsubstantiated" claims about the risks of eating meat. Headlines like "Vegetarian group slammed over advertising" splashed across the evening news. What "exaggerated" claims were targeted by the Agency? The vegetarian group claimed that meat-eaters were at increased risk of dying from heart disease and stroke, and that vegetarians lived longer than meateaters. How could the agency possibly find fault with such incontrovertible facts?
Because, simply put, our "facts" aren't true.
The latest science and the best science that we have that we have suggests that we vegetarians do not live longer than our meat-eating counterparts. The latest published results came out January, 2002 in a journal called Public Health Nutrition. Eight thousand vegetarians were followed for 18 years, and no survival advantage was found. Then April, 2002 the results of a study twice that size were released at the International Congress on Vegetarian Nutrition held at Loma Linda University. A study involving seventeen thousand vegetarians followed for about 9 years confirms the bad news-no survival advantage for vegetarians. Even more worrisome, both this huge studies found that vegetarians had an increased risk of dying from degenerative brain diseases
"Still On That Low-Carb Diet
by Steven Novella, Dec 14 2009
I have never been a fan of the low-carb diet craze - Atkins, South Beach, or whatever version you prefer. To me this was always a triumph of marketing over science. It is also an excellent example of how public opinion can be largely swayed by a few proponents and a compliant media, while the science goes off unnoticed in a different direction."
Each year, the National Center for Complementary and Alternative Medicine invites two leading figures in science and medicine to participate in the Distinguished Lecture series. The lectures provide a unique perspective on the evolution of complementary a

Factors that influence the cutaneous photosynthesis of previtamin D3. Science 211:590-593
When human skin was exposed to simulated solar ultraviolet radiation, epidermal 7-dehydrocholesterol was converted to previtamin D3. During prolonged exposure to simulated solar ultraviolet radiation, the synthesis of previtamin D3 reached a plateau at about 10 to 15 percent of the original 7-dehydrocholesterol content, and previtamin D3 was photoisomerized to two biologically inert isomers, lumisterol3 and tachysterol3. Increases either in skin melanin concentration or in latitude necessitated increases in the exposure time to simulated solar ultraviolet radiation required to maximize the formation, but not the total content, of previtamin D3. In order of importance, the significant determinants limiting the cutaneous production of previtamin D3 are (i) photochemical regulation, (ii) pigmentation, and (iii) latitude.

"ScienceDaily (Dec. 26, 2009) - Going back for a second dessert after your holiday meal might not be the best strategy for living a long, cancer-free life say researchers from the University of Alabama at Birmingham. That's because they've shown exactly how restricted calorie diets -- specifically in the form of restricted glucose -- help human cells live longer.
They found that the normal cells lived longer, and many of the precancerous cells died, when given less glucose. Gene activity was also measured under these same conditions. The reduced glucose caused normal cells to have a higher activity of the gene that dictates the level of telomerase, an enzyme that extends their lifespan and lower activity of a gene (p16) that slows their growth. Epigenetic effects (effects not due to gene mutations) were found to be a major cause in changing the activity of these genes as they reacted to decreased glucose levels.
"Western science is on the cusp of developing a pharmaceutical fountain of youth" said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "This study confirms that we are on the path to persuading human cells to let us to live longer, and perhaps cancer-free, lives.""
"A new study finds that obese people have brains that eight percent smaller than thin people and those brains look 16 years older.
Live Science.com reports that this condition makes it harder to think and puts people at greater risk for Alzheimer's and other diseases.
The results, based on brain scans of 94 people in their 70s, represent "severe brain degeneration," said Paul Thompson, senior author of the study and a UCLA professor of neurology. "
