All processed foods are banned, however, as are grains, beans and legumes, as it's thought that Paleolithic humans wouldn't have had access to the means of preparing and cooking these. Loren Cordain, professor of health and exercise science at Colorado State University, notes that Paleo is based on foods that humans have eaten for over 10, years, while tofu has been around for only 2, years.
Jonny Bowden points out the different types of tofu. The type of tofu used in such products as tofu hot dogs or tofu burgers likely has been highly processed and augmented with other ingredients, so it's not suitable under the Paleo plan. Basic tofu in its purer form is a more natural food and may be suitable for those on the Paleo Diet, says Bowden. Since tofu is made from soybeans, dieters can simply eat soybeans and avoid the tofu quandary entirely, says nutritionist and Paleo advocate Mark Sisson.
This is yet another reason to stay clear of factory-farmed animals: save yourself and the environment from soy. It should actually be the opposite where the farmers sue Monsanto for infecting their crops, but of course Monsanto is now too big to be vulnerable. They have a very strong political power because of the lobbying they do.

Goitrogenic effects of soy Soy contains high levels of goitrogens. Protease inhibitors in soy As if lectins and phytates where not enough, soy also has protease inhibitors, also called trypsin inhibitors.
Soy and estrogen This is a big problem. Men Improper balance of testosterone to estrogen in men can lead to a lower libido, fat accumulation around the waist and loss of energy, stamina and virility and even man boobs gynecomastia. Newborns What we feed our newborn child is always a first concern of course.
Soy is destroying the planet Some vegetarians argue that eating meat destroys the planet and that replacing meat protein with soy is a good alternative. First, grains are a product of modern agriculture; cavemen didn't nosh on bread. Second, grains are high in carbohydrates, which can spike your blood sugar.
Paleo critics point out that not all grains are created equal-whole grains do not spike your blood sugar as much as refined grains. Even so, paleo dieters still steer clear of grains because they contain different compounds and proteins like gluten, lectins and phytates, which they claim cause inflammation in the body and block other nutrients from being absorbed. Paleo critics say these compounds are not a problem unless you have an allergy or sensitivity. Learn more about the science behind lectins.
Legumes are members of a large family of plants that have a seed or pod. This category includes all beans , peas , lentils , tofu and other soy foods , and peanuts. This also includes peanut butter and soy sauce. Legumes are not allowed on paleo because of their high content of lectins and phytic acid.
Similar to grains, this is a point of controversy in the scientific community. In fact, lots of research supports eating legumes as part of a healthy diet because they are low in fat and high in fiber, protein and iron. Processed foods are full of the rest of the no-no's on the paleo diet: refined sugars, salt, refined vegetable oils and artificial sweeteners. Our ancestors didn't eat these foods. Plus, there is little argument in the scientific community that refined sugars and excess salt contribute to obesity, high blood pressure and heart disease.
There is some disagreement, however, over vegetable oils and artificial sweeteners. The American Heart Association recommends consuming corn, safflower and canola oils, but paleo plans say these are "not allowed" because of the ratio of omega-6 to omega-3 fatty acids and the way the oils are processed.
The U. Food and Drug Administration FDA condones artificial sweeteners as safe to consume, but they are not allowed on paleo since they are a man-made, processed food. Plus, although artificial sweeteners lower calories in food, research shows they can still cause us to crave sweets and that they can be harmful to our gut bacteria. A strict paleo diet does not allow dairy products because hunter-gatherers did not milk cows.
This includes milk, butter, yogurt, sour cream, and cheese. However, some paleo dieters say dairy is OK, especially if it is grass-fed because grass-fed butter, for example, has more omega-3s. Fermented dairy products like kefir are also OK for some paleo eaters because they have a lower content of lactose and casein, the two concerns paleo dieters have with dairy.
If you prefer to avoid dairy on the paleo diet, you can substitute non-dairy products made with coconut milk, almond milk, and cashew milk. This is a gray area. But tofu, unlike its cousins, also has all nine essential amino acids.
The meat they ate, which of course had fat, provided them with enough energy to survive some extremely harsh conditions. However, the soy they eat is unprocessed, unlike the soy we have access to in our grocery stores, which tends to be highly processed.
The fact that the US is the second-largest soybean producer in the world makes us a bit skeptical about any study concerning soy. Here on livinpaleocuisine. If you feel good about eating a particular food even though it might not be paleo, go ahead, put it in your diet.
