Vegetarianism - Wikipedia, the free encyclopedia - 1 views

  •  
    Vegetarianism is the practice of following a diet based on plant-based foods including fruits, vegetables, cereal grains, nuts, and seeds, with or without dairy products and eggs.[1] A vegetarian does not eat meat, game, poultry, fish, crustacea, shellfish, or products of animal slaughter such as animal-derived gelatin and rennet.[1][2][3] A vegan diet is a form of vegetarian diet which excludes all animal products, including dairy products, eggs, and honey. A lacto-vegetarian diet includes dairy products but excludes eggs, an ovo-vegetarian diet includes eggs but not dairy products, and a lacto-ovo vegetarian diet includes both eggs and dairy products. Vegetarianism may be adopted for ethical, health, environmental, religious, political, cultural, aesthetic, economic, or other reason A 1999 metastudy[22] combined data from five studies from western countries. The metastudy reported mortality ratios, where lower numbers indicated fewer deaths, for fish eaters to be .82, vegetarians to be .84, occasional meat eaters to be .84. Regular meat eaters and vegans shared the highest mortality ratio of 1.00. The study reported the numbers of deaths in each category, and expected error ranges for each ratio, and adjustments made to the data. However, the "lower mortality was due largely to the relatively low prevalence of smoking in these [vegetarian] cohorts". Out of the major causes of death studied, only one difference in mortality rate was attributed to the difference in diet, as the conclusion states: "vegetarians had a 24% lower mortality from ischemic heart disease than nonvegetarians, but no associations of a vegetarian diet with other major causes of death were established."[2

    Mortality in vegetarians and nonvegetarians: detailed findings from a collaborative analysis of 5 prospective studies. Key TJ, Fraser GE, Thorogood M, Appleby PN, Beral V, Reeves G, Burr ML, Chang-Claude J, Frentzel-Beyme R, Kuzma JW, Mann J, McPherson K. Am J Clin Nutr. 1999 Sep;70(3 Suppl):516S-524S. PMID: 10479225 Further categorization of diets showed that, in comparison with regular meat eaters, mortality from ischemic heart disease was 20% lower in occasional meat eaters, 34% lower in people who ate fish but not meat, 34% lower in lactoovovegetarians, and 26% lower in vegans. There were no significant differences between vegetarians and nonvegetarians in mortality from cerebrovascular disease, stomach cancer, colorectal cancer, lung cancer, breast cancer, prostate cancer, or all other causes combined.

High-dose fish oil for Lp(a) - The Heart Scan Blog - 1 views

  •  
    "Lipoprotein(a), or Lp(a), is a problem area in coronary plaque reversal. While our current Track Your Plaque record holder for largest percentage reduction in heart scan score has Lp(a), it remains among the more troublesome lipoprotein patterns. One unique treatment for Lp(a) is high-dose omega-3 fatty acids from fish oil. While the data are relatively meager, there is one solid study from Lp(a) expert, Dr. Santica Marcovina of the University of Washington, called "The Lugalawa Study." In this unique set of observations, 1300 members of a Bantu tribe living in Tanzania were studied. What made this population unusual is the fact that two groups of Bantus lived under different circumstances. One group lived on Nyasa Lake (3rd largest lake in Africa and reputed to have the greatest number of species of fish of any lake in the world) and ate large quantities of freshwater fish providing up to 500 mg of omega-3s, EPA and DHA, per day. Another Bantu group lived away from the lake as farmers, eating a pure vegetarian diet without fish. "

Maximizing Vegetarian Nutrition by Michael Greger, M.D. - Vegan news portal - 1 views

    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

    Blood pressure and atherogenic lipoprotein profiles of fish-diet and vegetarian villagers in Tanzania: the Lugalawa study. Pauletto P, Puato M, Caroli MG, Casiglia E, Munhambo AE, Cazzolato G, Bittolo Bon G, Angeli MT, Galli C, Pessina AC. Lancet. 1996 Sep 21;348(9030):784-8. PMID: 8813985 Interpretation In these villagers, consumption of freshwater fish (300-600 g daily) was associated with raised plasma concentrations of n-3 polyunsaturated fatty acids, lower blood pressure, and lower plasma lipid concentrations. In conclusion, our findings confirm that the favourable risk factor profile originally described for Eskimos living on a diet rich in n-3 polyunsaturated fatty acids is real, and not overestimated.

    A 1999 meta-study of five studies comparing vegetarian and non-vegetarian mortality rates in western countries found the mortality rate due to ischemic heart disease 26% lower among vegans compared to regular meat eaters, but 34% lower among ovolactovegetarians and those who ate fish but no other meat. No significant difference in mortality was found from other causes.[84] A 2003 review of three studies comparing mortality rates among British vegetarians and non-vegetarians found only a nonsignificant reduction in mortality from ischemic heart disease, but noted that the findings were compatible with the significant reduction found in the 1999 review The American Dietetic Association considers "appropriately planned" vegan diets "nutritionally adequate",[6] but poorly planned vegan diets can be deficient in nutrients such as vitamin B12,[87] vitamin D,[88] calcium,[88][89] iodine[90] and omega-3 fatty acids.[91] These deficiencies have potentially serious consequences, including anemia,[92] rickets[93] and cretinism[94] in children, and osteomalacia[93] and hypothyroidism[94] in adults.
