    National Cattlemen's Beef Association pays
    for Sadistic Anti-Vegan "Study"


    You may have heard about a study claiming that feeding a vegan diet to children is "unethical." What you may not have heard is that the "study" was paid for by the National Cattlemen's Beef Association. What's more the study itself was depraved and showed no regard for human life. Like Nazis experimenting on captives, the Cattle industry manipulated very slightly the diets of starving African children -- not to benefit the children but to try to produce some "scientific finding" which justifies meat-eating.

    2/22/05 - They say a little knowledge is a dangerous thing. Well, it's even more dangerous when it's wearing a lot of "respectable" titles.

    In one of the most irresponsible and flat out ignorant statements of recent days, Dr. Lindsay Allen, currently of the US Agricultural Research Service, told the annual meeting of the American Association for the Advancement of Science (AAAS) that a vegan diet was so lacking in necessary nutrients that it is tantamount to child abuse.

    Was this based on carefully conducted research? No. Was it based on structured study with control groups and meticulous monitoring of what children ate? No. Was it perhaps based on a large number of children eating a normal vegan diet who were found to have a greater than usual risk for illness? No. Her basis for this bizarre and completely unfounded declaration was her experience in Africa. Children who had been eating nothing but corn and beans were given a little meat and their health improved. Not children on a normal, healthy vegan diet - children who had been eating nothing but corn and beans. Adding almost anything to their diet would have caused improvement.


    --------------------------------------------------------------------------------







    --------------------------------------------------------------------------------
    Just eating beans and corn isn't an accurate representation of a vegan diet any more than it's an accurate representation of a kosher diet. So what do you find when you look at children who are eating a normal vegan diet?

    Children raised on fruits, vegetables, whole grains, and legumes grow up to be slimmer and healthier and even live longer than their meat-eating friends

    Vegetarian and vegan diets can be a healthy way of eating for all age groups

    Vegan diets can easily meet the nutritional needs of the growing child.

    So why, then would a USDA representative make such a ridiculous claim? Could the many and strong ties between the USDA and the meat industry be one reason?

    To find another, one need only look to who paid for this "study" -- none other than the National Cattleman's Beef Association. (See Footnotes)

    Surprise surprise.

    One of the more appalling aspects of this is that they are experimenting on starving children. These are kids who are clearly starving, they are not eating a "vegan" diet but a starvation diet. And yet these meat industry "researchers" don't feed the starving, they don't give them enough food, they do some weird pro-animal food experiment to try to twist it into a political point to help the bottom line of the meat industry.

    Imagine 554 children in rural Wyoming are eating a starvation diet that consists almost exclusively of beans and corn. As a result, many of them have stunted growth and are underweight. Nearly all of them suffer from a broad array of malnutrition-related illnesses. How many of them do you feed? All of them? Or do you decide to conduct an experiment to see what happens if you feed some and let the others continue to suffer for a couple of years?

    You'd feed all of them, of course. In the United States, deliberately starving children for research purposes is a criminal act that would provoke justifiable outrage. Unfortunately for the children in Dr. Allen's study, they were in Kenya.

    Dr. Allen and her colleagues are physicians and nutritionists. Whatever their questions were about the value of adding meat to a diet, they knew corn and beans is a starvation diet. Yet, in their Kenya study, more than 100 children were required to stay on that diet for nearly two years.

    While we know a great deal about the benefits of a vegan diet, there is always more to learn. Expanding the horizons of knowledge is a noble calling. But when we go beyond the bounds of human decency to advance the agenda of the National Cattleman's Beef Association, something is seriously wrong.

    Consider writing your Congressional representatives and demanding that that the USDA and meat industry stop experimenting on young, starving children, and ask for an investigation. You can find your representatives contact info here:

    Vesanto Melina RD comments:

    I was called by the BBC to respond to the story "Children 'Harmed' By Vegan Diets". I am co-author of "Becoming Vegan", by dietitians Brenda Davis and Vesanto Melina, distributed in the UK by Airlift books;
    www.airlift.co.uk.

    Lindsay Allen, of the US Agricultural Research Service had done a study in which providing animal products such as butter, cheese, milk, and meat improved the health and growth of impoverished and undernourished Kenyan children. Professor Allen failed to recognize that an assortment of plant foods that were nutrient rich and higher in protein and calories would have helped too. The findings from this study are not applicable to vegan children in the developed world.

    In our book "Becoming Vegan" we explain how to create a balanced and nutritionally adequate vegan diet. Everyone doesn’t automatically know to do this properly, and certainly the authors of this study didn’t. Whatever diet people use to raise their children, they typically need to learn a few nutrition pointers and tips about feeding children properly. For vegan diets this is particularly true as most vegans were not raised on this diet. But research has shown that it can be done and result in children of same height and weight statistically as the norms (though there tend to be fewer obese children among the vegan population.) Whatever their dietary choice, pregnant women and children are more vulnerable than people at other stages of the life cycle because of their fast rate of growth. It makes sense to take extra care in planning a nutritionally adequate diet for these stages.

    It is not true that animal products contain essential nutrients that are not found anywhere else. Animal products are unique sources of certain substances such as cholesterol. However dietary cholesterol is not essential; we make what we require in our bodies and too much may be a risk factor for disease. Vitamin B12 comes from bacteria and is present in animal products as a result of bacterial contamination. Properly designed vegan diets contain vitamin B12 from fortified foods or supplements. Vegans obtain sufficient calcium from fortified soy milk, calcium-set tofu; sesame seeds, almonds, blackstrap molasses, white or black beans; and greens such as kale; bok choy, Napa cabbage, and broccoli.

    Professor Allen's assertion that feeding children a vegan diet was unethical is unfounded, and reflects the fact that Professor Allen does not know how to create a nutritionally adequate vegan diet. Considering the risk factors related to in a diet high in animal products, it can be viewed as unethical to feed your child a diet high in animal products, and to set your child up for a future that increases his or her risk of various cancers, cardiovascular disease or diabetes.

    Brenda Davis RD comments:

    I would like to take this opportunity to respond to the statement by Lindsay Allen, from the University of California at Davis, "There is absolutely no question that it's unethical for parents to bring up their children as strict vegans.” Dr. Allen contends that vegan diets are nutritionally deficient and will delay or permanently impair development of children. Her allegations are based on a study of 554 school children in Kenya, in which malnourished children fed energy-deficient diets were divided into four groups – one that served as a control, and the other three that had beef, milk or oil added to their diets. Not surprisingly, adding animal foods to their diet improved growth and development of these children. If the researchers really wanted to prove the superiority of animal foods over plant foods, they might have provided the control group with protein-rich plant foods such as tofu or soy burger crumbles. This would seem to me a more ethical choice, considering the fact that these children were suffering from malnutrition. However, doing so would have demonstrated that it is not vegan diets that are inadequate, but rather energy, fat, and protein deficient diets that are inadequate. That would have defeated the purpose of the organization which funded the research, namely the National Cattlemen’s Beef Association (US).



    The question of adequacy of a vegan diet is one that has been thoroughly addressed in scientific literature.  The position of the American Dietetic Association, according to their most current position paper on vegetarian diets, is as follows:


    "It is the position of the American Dietetic Association (ADA) that appropriately planned vegetarian diets are healthful, are nutritionally adequate, and provide health benefits in the prevention and treatment of certain diseases."  The position paper goes on to add, "Appropriate planned vegan and lacto-ovo vegetarian diets satisfy the nutrient needs of infants, children, and adolescents and promote normal growth."



    The American Dietetic Association has long been regarded as a very reliable and conservative professional organization, and their position statements are made with great attention to research.  There is solid scientific evidence that vegan diets can be completely adequate when appropriately planned.  Two classic studies were done in the late 1980’s – one in Great Britain and the other in the United States.  Dr. Tom Sanders carried out the first study in Great Britain in 1988.  This study followed 39 vegan children for over 20 years. Dr. Sanders determined that these children grew normally, although they did tend to be slightly lighter than their omnivorous peers.  Dr. Connell did the second study in Summertown Tennessee in 1989.  This was also a long-term study looking at 404 vegan children.  This study found that the vegan children had a slower growth curve than omnivorous children, but that they caught up by the age of 10 years.  The vegan children developed completely normally – physically and intellectually. In both cases the authors conclude that provided the vegan diet is appropriately designed, it can meet all of the nutritional requirements of infants and children.



    There is no doubt that poorly designed diets result in malnutrition – whether the diets are vegan or omnivorous. Constructing a nutritionally adequate vegan diet has never been easier. Consuming a wide variety of legumes, vegetables, fruits, nuts and seeds, and ensuring sufficient calories, and reliable sources of vitamins B12 and D (several foods are fortified with these nutrients) will do the trick for most people. There are veggie “meats” that provide similar quality and quantity of protein and trace nutrients as meat, and non-dairy milks that provide similar amounts of calcium, vitamin D and B12 as cow’s milk. The plant-based alternatives come packaged with protective antioxidants and phytochemicals, instead of saturated fat and cholesterol. In a place where over 70% of the population will die of chronic degenerative diseases that are largely induced by low fiber, animal-centered, processed food diets, vegan diets are an attractive alternative. In fact, eating a plant-based diet will cut your risk of such diseases in half. A standard North American diet of cheeseburgers and fries, presweetened cereals, potato chips and soda pop is a far greater threat to health than a well-planned vegan diet will ever be.

    John McDougall MD points out more meat industry sponsorship of the publications and conferences involved in disseminating this "study" -- see his post here.

    Of further interest, here is an abstract on a recently published article by Professor Chandrasekhar in India. He used soy protein to improve the diet of Indian children, resulting in significant (P<0.01) improvement in the heights, weights and the hemoglobin levels of the children. Also, their morbidity pattern and cognition improved remarkably.

    This approach would be more economical, more ethical and healthier than feeding malnourished children meat in an atempt to improve these health parameters.



    Asia Pac J Clin Nutr. 2004;13(Suppl):S118. Soy proteins - an ideal functional food for growth promotion.
    Chandrasekhar U. former Dean,Professor & Head, Department of Food Science and Nutrition, Avinashilingam University,Coimbatore-641043,India.

    Introduction: Soy though a native food of South East Asia, it is a new under exploited food in the India context. Growth promoting effects of soy in health particularly among women and children is much-sought information under the current nutritional scenario in India, hence the objective of this research.

    Methodology: Defatted soy flour to replace the legume protein in the school lunch diet of preschool children (1200) was studied over a period of one year. Anthropometrics parameters, blood hemoglobin levels, clinical picture, physical and mental abilities of children formed the criteria for evaluation. In another attempt grade II malnutrition children (400) of 1-2 years of age were supplemented with the developed soy protein isolate (SPI) based food mix at a level (62g) to fill the calorie gap in their home diet and their growth parameters monitored over a period of one year.

    Results: Significant (P<0.01) improvement in the heights, weights and the hemoglobin levels of children given soy flour substituted lunch was observed. A decrease in the manifestation of clinical symptoms, significant improvements in the physical ability attributes and in the mental ability scores were evident. A proportionate increase with increases in the levels of substitution was also observed. Among the grade II malnutrition children given SPI based food mix, a significant improvement in their height (supplemented vs. control: 4.5 cm vs. 0.92 cm), weight (5.05 kg Vs 0.84 kg), arm, chest and head circumstances (0.29 cm vs. 0.07 cm; 1.30 cm vs. 1.09 cm and 1.24cm vs. 0.19 cm) respectively were recorded. 90.5 % of children in the supplemented group shifted to normal grade and the remaining 9.5 to grade I status. Their morbidity pattern and cognition improved remarkably.

    Conclusion: Considering the cost effectiveness of soy, this result on child growth undoubtedly signifies soy as the ideal functional food of the era for the promotion of good health of future generation

    沒錯,維生素B12可在肉類找到,但牛都是吃草的,B12不一定要由肉頰吸收,再者除了魚生,肉類一定要熟食,絕大部份維生素會流失

    [這篇文章最後由mensch在 2005/03/31 10:53pm 第 1 次編輯]

    作者:謝美芳

    民以食為天,在今日,大眾已漸漸覺醒到素食才是最健康的飲食。很多朋友自己吃素,但卻苦於不知如何給小孩吃素,在此我願意和大家分享我的心得。

    我的小孩(永為)是胎裡素,目前已兩歲四個月,仍吃素,從未喝過牛奶、吃過蛋。從出生至今,他的身材一直比同齡的小孩高大。在這兩年多之間,偶而有小感冒,都是在家調養即可,從未曾因為任何病痛而看醫生。別人眼中「吃素不營養,身體不好」的印象,在他身上一點也看不出來。

    永為是我唯一的小孩,在完全沒有經驗又沒有人可以請教的情況之下,我只好求助於書本。我最重要的參考書是《Pregnancy, Children, and the Vegan Diet》,作者是Michael Klaper,這本書是針對吃素而且不吃奶、蛋製品的孕婦、小孩所做的飲食建議。書上很清楚地列出嬰兒從何時開始可以吃何種食品,教父母如何開始為嬰兒添加副食品,如何為發育中小孩設計均衡的飲食,並且告訴讀者各種維他命、礦物質可以從那些非動物性食物中攝取。此書於一九八九年即已出版,可見素食育兒並非新觀念。書中也列出了許多健康有活力的素寶寶實例,例子中有許多素寶寶已經是青少年了。我想,此書足以左證素食育兒的好處,並給予想素食育兒的父、母親們足夠的信心。

    永為七個月之前完全喝母奶,七個月之後開始添加副食品。剛開始我餵他水果,如香蕉、刨絲的蘋果、蘋果泥(水煮蘋果再打成泥)、梨子等,慢慢的,我再讓他嘗試當季蔬菜,如紅蘿蔔刮絲、番瓜泥、打碎的芹菜等。此時的蔬菜,我都會煮爛並且打碎。

    他十個月大時,我開始餵食穀類、麵食,如蔬菜加糙米粥或拌面;一歲以後我才開始讓他吃豆類。每一次我餵他吃從未吃過的食物時,我會讓他連續幾天都吃同樣的食物,如此可以讓他的消化系統習慣這樣的新食物,並且可以很容易地觀察他對此食物的反應。

    在書中有提到幾樣不宜太早餵食嬰兒的食物,茲分述如下:

    菠菜及甜菜根含高量的硝酸鹽,最好等小孩十個月大後再餵食。
    高麗菜、美國花菜及白花菜容易引起消化方面的問題,最好一歲以後再餵食。
    酸性水果,如柑橘類、各類莓子及蕃茄等,也是一歲以後再餵食。
    蜂蜜,十四個月以後再餵食。
    我為永為準備食物時一定堅持如下幾項原則,第一、一定選用新鮮的有機材料;第二、一定要新鮮調理,不餵他隔夜的食物;第三、絕對不買現成的嬰兒食品,如罐頭、快餐麥片等。我是全職媽媽,所以可以這樣做。職業婦女可以使用新鮮的原料,一次多做一些再冷凍,用愛心做出來的食物也比沒有人性的罐頭營養成份要高。其實,我為永為準備的食物都在半小時內就可以完成,並不如想像中那麼費時間。

    小型電動食物處理機是我為永為準備食物必用的器具。我使用過不同的品牌,覺得美國品牌Cuisinart的Mini-Prep Processor(約美金三十元左右)是最佳選擇。雖然比別的品牌昂貴,但它的刀鋒較利,可以成功地打碎穀類及生菜,是其它便宜品牌辦不到的。我從永為七個月大一直用到將近二歲,每天用好幾次,可以說是最好的投資。

    永為剛開始吃蔬菜時,我會用食物處理機將苜蓿芽或生菜打碎,再加入鱷梨(avocado),拌成泥餵他。煮熟的蔬菜也可以用它來打成泥。

    煮糙米粥時,我都將糙米泡水過夜,第二天早上瀝干水份。要煮之前將糙米打碎,再加水或菜湯煮,如此只須煮十分鐘即可。一般煮糙米粥須花時間熬,我用這種方法可以很快煮熟,而且可以只煮小孩一次要吃的份量。在糙米粥中可以加蔬菜、泡過水且打碎的葡萄乾(使用水果干須先泡水隔夜)、豆腐、紅海藻等,小孩一歲後可加糖蜜、啤酒酵母粉等。

    永為一歲前的食物完全沒有調味,一歲之後,慢慢和我們吃一樣的食物,但在煮菜時,我會特別將菜燒軟些,並將他的部份拿出,再下調味品。

    在一歲半之前,他的食物我都會先切碎或打碎,即使是現在,我仍會將麵條或較粗的菜葉剪小段(此時,一把專用的剪刀很管用)。

    從他一歲半開始,每天早上我都會讓他先喝一杯現搾且稀釋過的果汁或果菜汁,並且在每餐之間讓他吃水果,他排便的次數似乎證明了「如果飲食正確,每餐都應該排便」。

    自從他斷奶之後,我偶而也會用堅果或種子類打成奶給他喝,用三分之一杯的堅果或種子(杏仁、葵瓜子、芝麻均可)加三杯半的水,放在果汁機中打勻,再過濾即可。

    現在,永為和我們吃得一樣,我並沒有特別為他準備什麼食物。他是一個胃口很好的小孩,我從來不須擔心他不吃東西。

    朋友告訴我,吃素,尤其是生機飲食這條路走得很寂寞,小孩稍有病痛就會聽到親友負面的打擊。即使是現在,有人看到健康活潑的永為還會問我,小孩吃素會不會營養不良?我想,當你有足夠的信心就不需要別人來肯定了。

    永為性情溫和、快樂,我相信這和他從出生就不造吃的殺業有很大的關係。每一位父母都希望提供小孩最好的生長環境,而讓永為從出生就吃素則是我們夫妻能給他最好的禮物。
