"The bottom line is that vegetarians and vegans aren't the only people eating 'fake' meat — meat eaters are also exploring this newfound protein superpower," said Beth Bloom, food and drink analyst at Mintel, in a statement.

Most popular in the meat substitute aisle are burgers, either made from veggies, wheat or soy, followed by fake poultry products, like Tofurkey, according to the survey. Women were slightly more likely than men to buy the foods.

So why all the enthusiasm for meat substitutes? The most common response among the 2,000 people Mintel surveyed on the web was that alternative meat products are healthy. After that, people said they chose fake meat because they were trying to reduce their meat consumption, and because they like the taste of the products. (As we reported last year, the selection has gotten better — 110 new meat substitute products came on the market in 2010 and 2011.)

Still, the majority of Americans don't buy meat alternatives. Among people who said they're not buying these products, 67 percent said it was because they prefer real meat. Another 34 percent said they don't like the taste of meat alternatives, while 20 percent don't like the texture.

Texture and flavor are likely to be the biggest hurdles for meat substitute entrepreneurs, like Ethan Brown of Beyond Meat (whom we profiled last year), who say they're hoping to break out of the health-food niche and sell to mainstream meat-eaters.
