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. https://www.youtube.com/watch?v=cwP8C9wjYaY
A diet high in phytic acid, which can be found in whole grains (it's in the bran) and beans like soy, is very detrimental for mineral absorption. Phytic acid strongly binds to minerals like calcium, iron, zinc and magnesium to form insoluble salts, phytates, which precipitate from the body and are not absorbed. Staffan Lindeberg has written a summary on phytic acid.
If you were to eat an unlimited amount of red meat (which the paleo diet technically allows), you may see your heart health suffer. While experts applaud the omission of packaged and processed foods like cake, cookies, chips, and candy — which are well known to be bad for your ticker — they’re not crazy about the fact that paleo doesn’t allow you to eat whole grains, legumes, and most dairy. Whole grains in particular have been linked with better cholesterol levels, as well as a reduced risk of stroke, obesity, and type 2 diabetes. (13) These are all comorbidities of heart disease. (14)
Even if eating only foods available to hunter–gatherers in the Paleolithic made sense, it would be impossible. As Christina Warinner of the University of Zurich emphasizes in her 2012 TED talk, just about every single species commonly consumed today—whether a fruit, vegetable or animal—is drastically different from its Paleolithic predecessor. In most cases, we have transformed the species we eat through artificial selection: we have bred cows, chickens and goats to provide as much meat, milk and eggs as possible and have sown seeds only from plants with the most desirable traits—with the biggest fruits, plumpest kernels, sweetest flesh and fewest natural toxins. Cabbage, broccoli, cauliflower, Brussels sprouts and kale are all different cultivars of a single species, Brassica oleracea; generation by generation, we reshaped this one plant's leaves, stems and flowers into wildly different arrangements, the same way we bred Welsh corgis, pugs, dachshunds, Saint Bernards and greyhounds out of a single wolf species. Corn was once a straggly grass known as teosinte and tomatoes were once much smaller berries. And the wild ancestors of bananas were rife with seeds. https://www.youtube.com/watch?v=SLoukoBs8TE
#1) If you’re not careful, this type of diet can get expensive. But as we know, with a little research, we can make eating healthy incredibly affordable. Admittedly, while I recommend eating organic fruits and veggies, free range chicken, and grass-fed beef whenever possible, these products can be a bit more expensive in conventional stores due to the processes needed to get them there.
I’ve always hated “fad” diets because any intelligent person should know elimination of an entire nutrient is dumb. I have bated around the idea of Paleo for a while and the more I read and think about it, and it does make the most sense. I am going to start working towards a more pure Paleo diet by cutting out the bread and pasta. I’m not committed to giving up coffee or tea, something not really addressed here. I mean you said do in steps right? We don’t want the caffeine withdrawals with the carb withdrawals. In my case I might loose my mind completely. So how do those beverages fit into this idea of eating Paleo?
Excluding foods. The exclusion of entire categories of commonly eaten foods like whole grains and dairy requires frequent label reading in the supermarket and in restaurants. It may also increase the risk of deficiencies such as calcium, vitamin D, and B vitamins, if these nutrients are not consistently eaten from the allowed foods or a vitamin supplement. For example, there are some nondairy calcium-rich foods that are absorbed well by the body such as collard and turnip greens or canned bone-in sardines and salmon, but you would have to eat five or more servings of these greens and fish bones daily to meet recommended calcium needs. (Note that some greens like spinach that are touted to be calcium-rich also contain oxalates and phytates that bind to calcium so very little is actually absorbed.) One small, short-term intervention study of healthy participants showed a 53% decrease from baseline in calcium intake after following a Paleo diet for three weeks.  Furthermore, the exclusion of whole grains can result in reduced consumption of beneficial nutrients such as fiber and thus may increase one’s risk for diabetes and heart disease.
The paleo diet (also nicknamed the caveman diet, primal diet, Stone Age diet, and hunter-gatherer diet) is hugely popular these days, and goes by one simple question: What would a caveman eat? Here, we explain what the paleo diet involves, its pros and cons, and, ultimately, what a modern person needs to know to decide whether or not to take the paleo diet plunge. https://www.youtube.com/watch?v=k_JUritU2IE
1. Meat: It’s not always for dinner. Cooking meat transforms it: Roasting it or braising it for hours in liquid unlocks complex smells and flavors that are hard to resist. In addition to converting it into something we crave, intense heat also breaks down the meat into nutrients that we can more easily access. Our ancient ancestors likely loved the smell of meat on an open fire as much as we do. https://www.youtube.com/watch?v=PUNe5SEqDw8
The Paleo diet includes nutrient-dense whole fresh foods and encourages participants to steer away from highly processed foods containing added salt, sugar, and unhealthy fats. However, the omission of whole grains, dairy, and legumes could lead to suboptimal intake of important nutrients. The restrictive nature of the diet may also make it difficult for people to adhere to such a diet in the long run. More high-quality studies including randomized controlled trials with follow-up of greater than one year that compare the Paleo diet with other weight-reducing diets are needed to show a direct health benefit of the Paleo diet. Strong recommendations for the Paleo diet for weight loss cannot be made at this time. https://www.youtube.com/watch?v=Sj4NJ6v-7A4
According to the model from the evolutionary discordance hypothesis, "[M]any chronic diseases and degenerative conditions evident in modern Western populations have arisen because of a mismatch between Stone Age genes and modern lifestyles." Advocates of the modern Paleo diet have formed their dietary recommendations based on this hypothesis. They argue that modern humans should follow a diet that is nutritionally closer to that of their Paleolithic ancestors. https://www.youtube.com/watch?v=DwVwQiqe4eM
Alcohol is a no-no if you are strict paleo. Beer is made from grains, and liquor also contains traces of gluten. But, good news for cider-lovers: most hard ciders are gluten-free, so they are allowed. Check the label to be sure. Red wine is more accepted in the paleo community because it contains the antioxidant resveratrol, but sorry chardonnay lovers, white wine is technically not allowed. https://www.youtube.com/watch?v=gYUx8rBOK-0
Grass-fed meat is recommended on the paleo diet because it is leaner than meat from grain-fed animals and has more omega-3 fatty acids, the healthy fats that reduce inflammation in the body and protect your heart. A typical American diet is high in saturated and trans fats and lower in healthy poly- and monounsaturated fats, hence the paleo diet's emphasis on grass-fed meats, as well as seafood. https://www.youtube.com/watch?v=mJK74-LC4hE
Origins and Evolution of Human Diet was an academic web site at the University of Arkansas devoted to discussion of evolution and the human diet. They had good articles on the conferences link. Here is one from the archives: Boyd Eaton's Evolution, Diet and Health which argues that current w-6 : w-3 imbalance together with absolute dietary DHA intake quite low in human evolutionary perspective may be relevant to the frequency of unipolar depression. https://www.youtube.com/watch?v=pmLd7AJpRsk

A number of randomized clinical trials have compared the paleo diet to other eating plans, such as the Mediterranean Diet or the Diabetes Diet. Overall, these trials suggest that a paleo diet may provide some benefits when compared with diets of fruits, vegetables, lean meats, whole grains, legumes and low-fat dairy products. These benefits may include: https://www.youtube.com/watch?v=OmNYKN96rqE
We strongly advise that you seek the professional advice of a health practitioner before you make any changes to your current diet and lifestyle and we do not suggest that you discontinue taking any medication you might have been advised to take. There are many long-standing myths and misconceptions surrounding cholesterol that we cover over the course of this program. That said, there are numerous peer reviewed papers showing a beneficial impact on all health-related markers, including cardiovascular and lipid profiles through the adoption of a dietary similar to what we advocate in The Paleo Way program. https://www.youtube.com/watch?v=mwmPsvCuzvo
