Antifungal RNA spray could help fight barley crop disease October 13, Spraying barley crops with RNA molecules that inhibit fungus growth could help protect the plants against disease, according to a new study published in PLOS Pathogens. Viral probe gives ringside view of cell-to-cell combat January 23, A fascinating blow-by-blow account of the arms struggle between plants and viral pathogens, is revealed in new research.
Cholesterol is a heavy weight molecule—an alcohol or a sterol—found only in animal foods such as meat, fish, cheese, eggs and butter. In the same year, according to the American Oil Chemists Society, Kritchevsky published a paper describing the beneficial effects of polyunsaturated fatty acids for lowering cholesterol levels.
Monounsaturated fatty acids are found in large amounts in olive oil, palm oil and lard; saturated fatty acids are found in large amounts in fats and oils that are solid at room temperature, such as butter, tallows and coconut oil. Rise of Coronary Heart Disease in the 20th Century Scientists of the period were grappling with a new threat to public health—a steep rise in heart disease.
While turn-of-the-century mortality statistics are unreliable, they consistently indicate that heart disease caused no more than ten percent of all deaths, considerably less than infectious diseases such as pneumonia and tuberculosis.
The greatest increase came under the rubric of myocardial infarction MI —a massive blood clot leading to obstruction of a coronary artery and consequent death to the heart muscle.
MI was almost nonexistent in and caused no more than three thousand deaths per year in Bythere were at leastMI deaths per year in the US. What life-style changes had caused this Edible vaccine research paper One change was a decrease in infectious disease, following the decline of the horse as a means of transport, the installation of more sanitary water supplies and the advent of better housing, all of which allowed more people to reach adulthood and the heart attack age.
The other was a dietary change. Butter consumption was declining while the use of vegetable oils, especially oils that had been hardened to resemble butter by a process called hydrogenation, was increasing—dramatically increasing.
By butter consumption had dropped from eighteen pounds per person per year to just over ten. Margarine filled in the gap, rising from about two pounds per person at the turn of the century to about eight. Consumption of vegetable shortening—used in crackers and baked goods—remained relatively steady at about twelve pounds per person per year but vegetable oil consumption had more than tripled—from just under three pounds per person per year to more than ten.
This was the lipid hypothesis, namely that saturated fat and cholesterol from animal sources raise cholesterol levels in the blood, leading to deposition of cholesterol and fatty material as pathogenic plaques in the arteries.
Petersburg, in which rabbits fed saturated fats and cholesterol developed fatty deposits in their skin and other tissues—and in their arteries. By showing that feeding polyunsaturated oils from vegetable sources lowered serum cholesterol in humans, at least temporarily, Kritchevsky appeared to show that animals findings were relevant to the CHD problem, that the lipid hypothesis was a valid explanation for the new epidemic and that by reducing animal products in the diet Americans could avoid heart disease.
The lipid hypothesis did not hold up to these population studies, nor did it explain the tendency to fatal clots that caused myocardial infarction.
Panelists presented the lipid hypothesis as the cause of the heart disease epidemic and launched the Prudent Diet, one in which corn oil, margarine, chicken and cold cereal replaced butter, lard, beef and eggs. But the television campaign was not an unqualified success because one of the panelists, Dr.
Dudley White, disputed his colleagues at the AHA. White noted that heart disease in the form of myocardial infarction was nonexistent in when egg consumption was three times what it was in and when corn oil was unavailable. When pressed to support the Prudent Diet, Dr.
Back in the MI free days beforethe fats were butter and lard and I think that we would all benefit from the kind of diet that we had at a time when no one had ever heard the word corn oil. Club members used corn oil and margarine instead of butter, cold breakfast cereals instead of eggs and chicken and fish instead of beef.
Jolliffe, an overweight diabetic confined to a wheel chair, was confident that the Prudent Diet would save lives, including his own. In the same year, the food industry initiated advertising campaigns that touted the health benefits of their products—low in fat or made with vegetable oils.
A typical ad read: However, both experiments had nothing to do with CHD, and the clinical trial did not find that reducing blood cholesterol had any effect on CHD events. William Castelli, Director of the Framingham Study was one of several specialists to endorse Puritan.
In the AHA published its first dietary guidelines aimed at the public. The authors, Irving Page, Ancel Keys, Jeremiah Stamler and Frederick Stare, called for the substitution of polyunsaturates for saturated fat, even though Keys, Stare and Page had all previously noted in published papers that the increase in CHD was paralleled by increasing consumption of vegetable oils.
In fact, in a paper, Keys had suggested that the increasing use of hydrogenated vegetable oils might be the underlying cause of the CHD epidemic.
