The Paleo diet is a modern take on what our hunter-gatherer ancestors might have eaten millions of years ago during the Paleolithic era. Think lean meats, wild fish, eggs, nuts, fruits, and vegetables – the staples of a pre-agriculture lifestyle. While not an exact replica of ancient diets (our ancestors had much fewer food choices!), this dietary approach emphasizes whole, unprocessed foods while steering clear of modern conveniences like grains, legumes, dairy, and added sugars.
This restrictive eating plan gained popularity thanks to scientist Loren Cordain’s 2002 book “The Paleo Diet,” which argues that these modern staples are largely responsible for today’s health woes. Cordain posited that humans evolved to thrive on the foods readily available during the Paleolithic era, and deviating from this natural blueprint has led to an increase in chronic diseases like obesity, diabetes, and heart disease.
What Can You Eat on Paleo? 🥩🍎🌱
A Paleo diet prioritizes nutrient-dense whole foods:
- Meat & Poultry: Beef, lamb, chicken, turkey, duck – all lean choices are best.
- Seafood: Salmon, cod, tuna, shellfish – prioritize fatty fish for omega-3s.
- Eggs: Whole eggs and egg whites are both on the menu.
- Vegetables: Load up on leafy greens, root veggies, cruciferous vegetables, and more.
- Fruits: Berries, apples, pears, peaches – opt for lower-sugar options.
- Nuts & Seeds: Almonds, walnuts, pumpkin seeds, chia seeds – good sources of healthy fats and protein.
You’ll also find healthy fats on the Paleo list: olive oil, avocado oil, coconut oil, and ghee (clarified butter). Herbs and spices add flavor without adding unnecessary ingredients.
What to Avoid 🚫🌾🧀🍫
The Paleo diet’s strictness stems from cutting out what proponents consider “modern” food additions:
- Grains: Wheat, rice, corn, oats, barley – all grains are off-limits.
- Legumes: Beans, lentils, chickpeas, and peanuts are restricted.
- Dairy: Milk, yogurt, cheese – all dairy products are excluded.
- Refined Sugar: White sugar, brown sugar, honey, agave – sweeteners are generally avoided.
- Ultra-Processed Foods: Chips, candy bars, packaged snacks – highly processed items are eliminated.
Some oils (canola, corn, soybean) and artificial sweeteners also need to be cut out.
Potential Benefits 💪🩸⚖️
While more research is needed, some studies suggest the Paleo diet may offer these benefits:
-
Improved Blood Sugar Control: Restricting refined carbs and sugar can lead to lower blood glucose levels, which can benefit those with type 2 diabetes or insulin resistance.
-
Weight Loss: Increased protein and fiber content promotes satiety, potentially leading to reduced calorie intake.
- Reduced Risk Factors for Heart Disease: Some studies have shown improvements in triglyceride levels, blood pressure, and cholesterol ratios on a Paleo diet.
Caveats & Concerns 🤔
Despite potential benefits, the Paleo diet isn’t without drawbacks:
- Nutrient Deficiencies: Cutting out entire food groups like legumes and dairy could lead to deficiencies in calcium, iron, and fiber unless carefully managed with supplementation or fortified alternatives.
- Gut Health: Some studies suggest a strict Paleo diet might negatively impact gut microbiome diversity, potentially impacting overall health.
- Sustainability Concerns: Emphasizing meat consumption raises ethical and environmental concerns regarding its carbon footprint and resource use.
Paleo vs. Keto: Not Quite Twins
The ketogenic (keto) diet is another popular low-carb approach, but it’s even stricter than Paleo. While both minimize carbs, the keto diet drastically restricts them to less than 50 grams per day, forcing the body into ketosis – a state where it burns fat for fuel instead of glucose.
The Paleo diet allows more carbohydrates from fruits and starchy vegetables, making it less restrictive in that regard.
While the Paleo diet offers potential health benefits by emphasizing whole foods, its strictness raises concerns about nutrient adequacy and sustainability. As with any dietary change, it’s essential to consult a healthcare professional or registered dietitian before adopting the Paleo diet to ensure it aligns with your individual needs and goals
