    ABP --- Working hard for the conventional value chain!

    The following article is on the newest version of ABP's Out and About weekly email newsletter. I guess ABP has decided to take these radical nonconformist's on front and center. I rememeber when one of the past ABP chairs, and a man I consider to be a friend, told me to sell on my postivies rather than run down the competition. Maybe he could give that advice to this new crew at ABP.

    How on earth is someone supposed to support this organisation. (and believe me I have been trying lately)
    Patting themselves on the back for a $2.29 per ear tag subsidy and totaly ignoring an opportuntiy to support mediation of a Class action suit that would not only hold those responsible --- responsible, but would help every primary producer in this country in a time of great need..

    Maybe I'm just having a bad hair day.

    Happy reading.

    And when you get to the end of the article -- please know that there are plenty of studies past and present which talk about the attributes of other supplementary nutrients such as fats or lipids in beef.



    "For the last three Monday evenings, CBC’s “Ideas” has had a series on Canada’s meat sector: the pros and cons of eating beef and other animal products. During the last program there was considerable discussion on the differences between “industrial beef,” that product that comes from conventional feedlots compared with grass-fed finished beef. It seemed that much of the discussion was pro grass-fed with only anecdotal reasons why this was so.

    A recent scientific study at the Texas A&M University shed some light on this.

    Dr. Stephen Smith, an AgriLife Research meat scientist, and a team of researchers have found that contrary to popular perception, ground beef from pasture-fed cattle had no beneficial effects on a person’s plasma lipid.

    However, high monounsaturated fat ground beef from grain-fed cattle increased HDL cholesterol, increased LDL particle diameters, and decreased insulin, suggesting that ground beef produced by intensive production practices provides “a healthful, high-quality source of protein.” HDL cholesterol is considered to be the “good” cholesterol; small, dense LDL is associated with increased risk of developing coronary heart disease. Increased LDL particle diameters would serve some protection against heart disease.

    The researchers wanted to see if product from pasture-fed and grain-fed cattle had different effects on LDL or HDL cholesterol. None of the scientific literature to date could justify statements that pasture-fed beef is better for a person.

    The study used Angus cattle raised at the University’s McGregor AgriLife Research Center. One group of cattle was fed a pasture diet supplemented with hay. The steers were kept on pasture until 20 months of age (Group A – pasture fed).

    A second group of Angus steers was fed the same way as a conventional feedlot would feed them; they were kept on a corn-based diet until 16 months of age to reach USDA Choice status (Group B – USDA choice).

    A third group of Angus steers was fed the corn-based diet the longest, until reaching USDA Prime grade (Group C – USDA prime). The fat in cattle that are high in marbling is low in saturated and trans-fats, and higher in monounsaturated fats.

    Beef cuts from the plate and flank taken from all three grades were made into a ground beef product, containing 24 per cent fat.

    Next, a group of 27 men completed a three-way crossover study. Each group rotated, consuming five 114-gram ground beef patties per week for six weeks from each of the three sets of cattle used in the study.

    There really were no negative effects of feeding ground beef from the pasture-fed cattle (Group A). However, they did see several positive effects in men that consumed ground beef from grain-fed cattle. The ground beef from the USDA Prime cattle (Group C) increased HDL cholesterol and LDL particle diameter. Both effects are protective against cardiovascular disease. The Prime ground beef also decreased insulin, suggesting some protective effect against type II diabetes. According to the research team the healthier product came from beef with more marbling.

    Beef is a healthy, tasty, nutritious product that is enjoyed daily by consumers across the country. Beef as a protein source is well known; the attributes of other supplementary nutrients such as fats or lipids has not been fully explored."

    New CLA study targets promise to battle obesity and related conditions

    Edmonton, Alta., June 9, 2010: Help in battling the 'globesity' epidemic could come from a natural component of dairy and beef products.

    A new study led by University of Alberta researchers is looking into the promise of natural conjugated linoleic acid (CLA) to fight obesity and related conditions such as type-2 diabetes and the metabolic syndrome. Vaccenic acid (VA), a natural CLA 'precursor' that shows similar and related potential benefits, will also be evaluated.

    "The knowledge from this study will give us a clearer picture not only of the benefits of natural CLA and related VA but also the mechanisms that underlie those benefits," says Dr. Spencer Proctor, Director of the Metabolic and Cardiovascular Diseases Laboratory at the Alberta Institute for Human Nutrition (AIHN). "This is a critical step toward strategies to take advantage of these benefits. It will also strengthen the foundation of science to support future human clinical trials."

    Proctor is Science Lead of the CLA Network, a Canada-based multi-disciplinary network focused on understanding the health potential of natural CLA and other beneficial dairy and beef fatty acids or lipids. Proctor and other members of the AIHN research team were recently in Europe presenting the latest findings from their program to international colleagues at the International Symposium on Chylomicrons in Disease (ISCD) and at the International Society for the Study of Fatty Acids and Lipids (ISSFAL).

    The incidence of obesity and associated metabolic disorders has reached epidemic proportions in Canada and in many parts of the world - a trend coined the "globesity epidemic." With approximately $4.3 billion per year spent on obesity and obesity related diseases in Canada alone, it's easy to see why progress in understanding CLA's potential to guard against obesity is one of the most important areas of CLA research.

    CLA and related VA in their natural forms are produced only by ruminant animals such as dairy and beef cattle. A portion of CLA and VA is naturally present in the milk and meat from these animals and a growing body of research points to these components as healthy fats with a variety of potential benefits for battling chronic diseases.

    One of these potential advantages supported in recent findings by AIHN and others is that natural CLA and related VA play a beneficial role in body weight regulation, which protects against obesity and related chronic conditions. However, there is limited information on exactly how this happens - in other words, what the mechanisms are.

    Proctor and colleagues have a head start on the scientific detective work. Research to date has established that the effects of CLA on modulating body fat are mainly linked to increased energy expenditure and improved lipid metabolism. This points toward CLA having an effect on certain neurological pathways that are known to regulate these areas.

    "This is the theory we plan to test," says Proctor. "If we can show this is the case and understand more specifically how it happens, this will provide a major leap forward in the science. It would open up a lot of opportunity, including potential for CLA-enriched products to carry health claims as functional foods to reduce the risk of both type-2 diabetes and cardiovascular diseases."

    The research team will use an animal model it has established as leading model for evaluating the potential of dietary CLA and VA, which will be supplied in the form of CLA-enriched dairy products.

    "The findings of this study have the potential to directly establish additional health benefits of dairy products and provide a more complete picture of the role of these products in human health," says Proctor.

    Notably, a study was recently published that examined CLA in overweight children for seven months with some positive benefits on weight (Racine et al, American Journal of Clinical Nutrition, May 2010).

    The new AIHN study will strengthen this steadily expanding body of knowledge. It is supported in part by the Dairy Farmers of Canada (DFC). In addition to DFC, livestock industry support for CLA Network human health research to date has also been provided by Alberta Milk and the Beef Information Centre (BIC). As well, major support for a large portion of Proctor's ongoing CLA and VA research is provided through funding originally awarded through the Alberta Livestock Industry Development Fund (ALIDF) and now managed through the Alberta Livestock and Meat Agency (ALMA).
