What is the paleo diet?

There’s a lot of information out there on the paleo diet, and a lot of people interpret it to their own liking. According to thepaleodiet.com, which happens to be founded by Dr. Cordain himself, “When you get down to the basics, it’s just eating a lot of vegetables, fruits, lean meats, fish, eggs, and some nuts and seeds — what you find at your local farmer’s market.” It tends to be higher on the protein side, with lots of fresh fruit and vegetable varieties included as well.

Why does the diet work?

According to Dr. Cordain’s research, this way of eating is how we as humans have evolved over time and what our prehistoric ancestors ate and adapted to. It flips the script on the recent standard of the Western diet, where almost everything is easily accessible, prepackaged, convenient, and processed. As a result, the worldwide obesity rate has nearly tripled since 1975, with 13% of adults suffering from obesity as of 2016.

By eliminating processed foods and inflammatory-triggering foods, we can reduce things like chronic body inflammation and other comorbidities like high blood pressure, heart disease, diabetes, hypertension, and more. Though the paleo diet has evolved throughout the years, and subcategories of the diet have branched off, let’s take a look at some of the typical foods to include and avoid while on the diet.

Foods to eat on the paleo diet

  • Vegetables: Broccoli, kale, spinach, lettuce, cucumbers, squash, carrots, peppers, etc.
  • Fruit: Berries (blue, black, straw, rasp), bananas, oranges, apples, avocados, etc.
  • Animal by-products: beef, fish, chicken, pork, lamb, turkey, eggs, seafood (shrimp, sardines, etc.)
  • Nuts/seeds/tubers: Sweet potatoes, potatoes, yams, turnips,  pumpkin seeds, almonds, hazelnuts, walnuts, macadamia nuts, etc.
  • Miscellaneous: Oils (Olive, coconut, avocado), Salts (sea, Celtic, pink Himalayan), rosemary, turmeric, garlic, curcumin, etc.
  • Others: Since the diet has been knocked for lacking things like calcium, others have learned to incorporate things such as full-fat or raw dairy to get some natural calcium
  • Full-fat or raw dairy: Butter, milk, cheese, yogurt
  • Occasional indulgence: Wine, coffee, teas, and dark chocolate (70% cocoa or higher) are all extremely good antioxidants

  • Highly processed foods: Pre-made meals (frozen pizzas), pre-packaged snacks (granola bars), canned foods (fruit and veggies), foods labeled as “low-fat” and or “diet”
  • Legumes: Beans, lintels, peas, etc.
  • Sugars and syrups: Table sugar, high fructose corn syrup, corn syrup, fruit juices, anything with additional sugar
  • Artificial sweeteners: Aspartame, sucralose, saccharin, acesulfame, potassium, etc.
  • Grains: Breads, pastas, wheat, barley, etc.
  • Vegetable oils: Peanut, sunflower, soybean, grapeseed, safflower, corn, cottonseed, etc.
  • Trans fats: Partially hydrogenated or hydrogenated oils

To keep things super simple, if you cannot buy it at your local farmers market, you probably shouldn’t be eating it, especially if those ingredients are made in a factory.

  • Eliminates processed foods: Highly processed foods have been linked to almost every type of health issue, from diabetes to obesity, high blood pressure, etc. Removing those from an individual diet can have positive health improvements.
  • Removes added sugars: Again, like processed foods, artificial sweeteners and added sugars are horrible for overall health, and removing them can be extremely beneficial.
  • Weight management and weight loss: By removing a lot of key inflammatory food groups, individuals will report great weight loss on the paleo diet.
  • Improves health biomarkers:
    1. Glucose control
    2. Improved body fat
    3. Lowers high blood pressure
    4. Healthy cholesterol levels

Cons of the paleo diet

  • Lacks some key vitamins: Diet does not lead to adequate amounts of vitamin D or calcium, which leads many to supplement and add in full-fat or raw dairy products
  • No grains: Grains have been shown to be beneficial in those who do not have gluten intolerance and can help with regularity. It’s easy to find gluten-free food products nowadays, either.
  • No dairy: Depending on how strict you follow, some who follow paleo say that in order to be true paleo, no dairy should be consumed. However, full-fat and raw dairy products can help provide enough calcium, which is extremely important for bone health as we age.

Our take on the paleo diet

The paleo diet is a great starting place for most people who want a sensible approach to the world of healthier eating habits. While demonizing or eliminating food groups altogether can have its disadvantages, a more appropriate starting place would be something paleo-adjacent. Following the paleo diet while also making sure to consume enough dairy or gluten-free grains, as well as ample carb sources, has been proven very beneficial for overall well-being.

Why Irish whiskey deserves more than just a St. Patrick’s Day toast

Scotch

Since we’re only a few days from St. Patrick’s Day, the timing is right to get into the world of Irish whiskey. But if March is the only time of the year when you crack open a bottle of Teeling, Redbreast, or Green Spot, you’re really missing out on some exceptional Irish whiskeys for the remaining 11 months.

In my almost two decades of writing about alcohol, I’ve encountered whiskey from all corners of the globe. And I learned that there might be no whiskey style more underrated than Irish whiskey. There’s so much more to this geographically specific whiskey style than just Jameson, Bushmills, and Tullamore D.E.W. (although all of these brands deserve a spot on your home bar).

Coffee beans

If you've been blessed with a stomach free of digestive issues, chances are you haven't given much thought to coffee's acidity. Yet, those of us with troublesome digestive systems know that coffee is an acidic drink with a pH level of 4.8 and 5.1, depending on the roast. The acidic nature of coffee can exacerbate various common conditions like IBS and acid reflux. I know this all too well as someone who drinks too much coffee daily.

Since giving up coffee is not an option, many wonder if switching to decaf is a good alternative. But is decaf coffee acidic, too? As it turns out, switching to decaf doesn't help much in lowering acidity. Here's what to know before you switch to drinking decaf.
