With a vegan diet you're not sure to lose weight but you're very likely to. According to a research paper, based on about 65 thousands of people, vegans were showing lower BMI than vegetarians and omnivorous (this means they were thinner). Also in several other clinical trials (Barnard 2009; Jenkins 2009; Barnard 2005; Barnard 2006; Ornish 1998) the ...

This is clearly hard to answer, as it is very broad, but there are relevant sources on the matter. Intelligence - vegetarians may be more intelligent than average - according to this study that examined the relation between IQ in childhood and vegetarianism in adulthood: Higher scores for IQ in childhood are associated with an increased likelihood of ...

Those statistics may be misleading. Some people only practice vegetarianism for particular times such as fasting for religious reasons or financial reasons. Many of my non-vegetarian family members didn't eat meat while flatting at university to simply save money. Other people stop being vegetarian once they leave their parents home or travel abroad, ...

The 2013-study "Redefining agricultural yields: from tonnes to people nourished per hectare" by Cassidy et al. from the University of Minnesota investigates this question. The authors state that given the current mix of crop uses, growing food exclusively for direct human consumption could, in principle, increase available food calories by as much as 70%,...

This 1999 study of students in the Flemish region of Belgium indicated that vegetarian youth had lower performance on strength tests but higher performance on endurance tests. The study had several limitations, including a small sample size. Hebbelinck et al. (1999) conducted anthropometric analyses (stature, weight, skinfold thicknesses), puberty ratings ...

Yes, a bean-laden vegan diet is likely to cause a larger volume of flatulence. A 2011 study published in BMC Nutrition concluded that incorporating beans (an important staple food for vegans) has the potential to increase flatulence, but for many people this effect may only be temporary. First, perception of flatulence increase is variable by bean type ...

The Standard American Diet now comes in vegan. More on that below. In my anecdotal experience, losing weight simply by going vegan is less likely than one might think and indulges in magical thinking. I am skeptical of studies I have seen so far, in the sense that they have not passed sanity checks regarding correlation v. causation, long-term impact and ...

Faunalytics collected data on current and former vegetarians in May 2014 and released a number of reports with findings on the data. The process of moving away from a vegetarian or vegan diet is multifaceted and complex, and the same appears to be true for anticipating a return to one of these diets. Former vegetarians/vegans were asked to give the ...

I did a report on vegetarianism in college, and back then-- when I had access to a university library-- I found that we would increase our global food supply by at least 40%, enough to sustain another 3 billion people. I can't find my source now, and most "What would happen if everyone went vegetarian?" articles focus mainly on climate change and the economy,...

There is a response to that paper: Matheny, G. (2003). Least harm: A defense of vegetarianism from Steven Davis's omnivorous proposal. Journal of Agricultural and Environmental Ethics, 16(5), 505-511. which gives some numbers in terms of kg of protein (emphasis mine): Davis suggests the number of wild animals killed per hectare in crop production (15) ...

This is an interesting one ! My reading of the research on this matter is that the main area of concern is not the consumption of soy itself. It is the consumption of genetically modified soy that is resistant to "Roundup" - the most widely used herbicide globally, of which the main active ingredient is glyphosate. This is toxic and carcinogenic, and ...

provisionnal answer in wait for access to the referred article According to wikipedia on vitamin K2 and K the European Food Safety Authority set an "Adequate Intakes" at 70 micrograms a day for vitamin K. Again according to wikipedia, you can get vitamin K2 out of natto. The use of an "Adequate Intakes" instead of a recommended dietary allowances and no ...

I found many sources claiming that "most" of the vitamins and minerals are preserved through the juicing process. The only quantitative statement I found was an unsourced quote from this question on Quora. Very little of micronutrients found in fruits and vegetables are thrown out with the insoluble fiber. In fact, the Department of Agriculture found that ...

Not automatically, no. With any dietary change there will be healthy and not so healthy ways to do it. To become vegan and maintain or lose weight rather than gaining it you have to be careful of adding extra calories. Some things I've read have suggested that it is often the case that vegan meals have a lot of the "tasty" non-vegan things like cheese and ...

It's depends on if you make other healthy lifestyle choices. Studies just comparing BMI and diet may be affected by confounders: Vegans are often choose to their lifestyle due to concerns about health and the environment. There is no universal vegan diet, there are a lot of personal choices involved and any study may not be representative of your actual ...

Beans are a common source of protein among people on a vegan diet. One aspect I can speak to is that when cooking dry beans, they're almost always soaked first. By discarding the soaking water prior to cooking, even though some nutrition (in the form of minerals) is lost, you get rid of up to 80% of the oligosaccharides that cause flatulence.

What is a multigrain food item? Here's the multigrain labelling requirements in Canada: Multi-grain products require 2 or more grains to be present in an amount of 2% each or more. For the purpose of a multi-grain claim, the following are considered grains: Soybean, safflower, peas, corn, flaxseed, wheat, rapeseed, oats, mustard seed, barley, beans, ...

There is some very weak evidence that soy lowers testosterone, for example, Dillingham et al (2005) and Goodin et al (2007), however the former has a very small sample size and neither study utilised a control group. The vast majority of research shows no effect. In general, rather than relying on individual studies which have their own idiosyncrasies and ...

By analyzing the the soybean chemically, we know that soy is chemically high in phytoestrogens, the organic compound that mimics estrogen. Thus, the common conceptions of it's link to hormonal imbalances. Based on the research I found, the link between soy and decreased testosterone more than a correlation. Studies This study follows a 19 year old man who ...

Soy does not lower testosterone. Here is a video, where the guy explains exactly why this is the case. He looks at the "evidence" suggesting that this is the case, then explains (with evidence) why this "evidence" does no hold much weight. He also shows a lot of evidence that soy does NOT lower testosterone. This video is 30 mins long, however he explains (...

The largest survey about choice of companion animals in the United States is the APPA National Pet Owners Survey and this survey doesn't appear to ask whether people identify as vegan. However, it costs $3500 to obtain a copy of the document so I can't conclusively confirm that. I was not able to locate any other research surveys or polls about which ...
