But human populations in different regions of the world ate a variety of diets. Some ate more; some ate less. They likely ate meat only when they could get it, and then they gorged. Richard Wrangham, author of Catching Fire: How Cooking Made Us Human, says diets from around the world ranged greatly in the percentage of calories from meat. It’s not cooked meat that made us human, he says, but rather cooked food.
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars.  The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
You’d think vegan and paleo sort of cancel each other out, with paleo diet recipes emphasizing grass-fed meats and free-range eggs and vegans avoiding all animal products. But when you think about what our “ancestors” probably really ate, it must have been a very plant-based diet. So, what does an ancestral vegan diet look like? Abundant fruits and veggies are something both eating philosophies have in common. Grains and legumes — go-tos for many vegans — are out, but paleo-friendly starches like sweet potatoes, yams, cassava and plantains are in, and they’re both tasty and filling. So are all the good fats, like nuts, avocados and olive oil. And we can sweeten things up when we need to with fruit juices, honey, molasses, pure maple syrup and dried fruits. This is starting to sound not only healthy, but also deliciously doable. Here are 18 tempting recipes that’ll have you saying: “Let’s do this!”
If years of unhealthy eating have wrecked your metabolism and you’re carrying around extra body fat, switching to a Paleo diet will certainly help your body composition and overall health. But the point of eating Paleo is not to shed as many pounds as possible so that you can fit into the jeans you wore in high school. This nutritional approach is about optimizing your health and wellness – not transforming you into a waiflike size zero runway model with that special heroin-chic je ne sais quoi.
For immediate weight loss, Paleo is a great and healthy solution. But after carefully reading and considering, I’m unconvinced that Paleo is optimal for long-term health. I think, in fact, it might lead to heart disease and other ills associated with heavy meat consumption. Although many of Cordain’s theories fall apart long-term, I thoroughly enjoyed the read and highly recommend the book. You should read critically and decide for yourself.

1. Crispy Plantains With Garlic Sauce: A staple of Caribbean cuisine, plantains are delicious fried or mashed. Ripe ones look similar to bananas and can be used in sweet dishes, while green ones mash and crisp up nicely. In this recipe, green plantains are parboiled, smashed and pan-fried, so the center remains soft while the edges provide crunch. The accompanying garlic-lime dipping sauce is sinfully delicious.
