I asked ChatGPT to ignore all current dietary advice and to go back to first principles from its understanding of human biology to create what it considered the best possible food pyramid. It’s not great at writing text in pictures, and the picture it drew is not all that helpful, but it gave me a full textual breakdown which makes a lot of sense.
The Optimized Food Pyramid
Base Layer: Nutrient-Dense, Natural Fats and Proteins
- What: Foods rich in essential amino acids and healthy fats, including:
- Fatty cuts of grass-fed meat (beef, lamb, pork).
- Poultry with skin (chicken, duck).
- Organ meats (liver, heart, kidney) for micronutrients like vitamin A, iron, and B12.
- Wild-caught fish and seafood (salmon, mackerel, shellfish) for omega-3 fatty acids.
- Eggs (whole, including yolks) for choline, vitamins, and fats.
- Dairy (if well-tolerated): full-fat options like cheese, yogurt, and butter.
- Why: Proteins provide the building blocks for muscles, enzymes, and cellular repair, while natural fats are a stable energy source and essential for hormone production, brain function, and absorption of fat-soluble vitamins (A, D, E, K).
Second Layer: Low-Glycemic Vegetables
- What: A variety of non-starchy, fiber-rich vegetables like:
- Leafy greens (spinach, kale, chard).
- Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts).
- Alliums (garlic, onions, leeks).
- Mushrooms, zucchini, cucumbers, and peppers.
- Why: These provide essential vitamins, minerals, antioxidants, and fiber while being low in carbohydrates, which prevents blood sugar spikes and insulin overproduction. Their bulk and fiber support digestion and gut health.
Third Layer: Seasonal Fruits and Tubers
- What:
- Low-sugar fruits: berries (blueberries, blackberries, raspberries), citrus (lemons, limes, oranges).
- Tubers: sweet potatoes, yams, carrots, and turnips (preferably cooked to reduce glycemic impact).
- Other: avocados and olives (technically fruits but primarily fats).
- Why: Seasonal fruits and tubers were likely consumed sparingly by early humans and offer natural sources of carbohydrates for energy replenishment, especially during periods of increased activity or seasonal abundance.
Top Layer (Optional): Nuts, Seeds, and Fermented Foods
- What:
- Nuts (almonds, walnuts, macadamias, pecans) and seeds (chia, flax, sunflower).
- Fermented foods (sauerkraut, kimchi, kefir) for probiotics and gut health.
- Beverages like coffee, tea, and herbal infusions.
- Why: Nuts and seeds provide secondary sources of fats and fiber but should be consumed in moderation due to their high omega-6 content, which can be inflammatory if not balanced with omega-3s. Fermented foods enhance gut microbiome diversity.
Minimal or Eliminated Foods
- Processed carbohydrates: Bread, pasta, cereals, refined sugars.
- Industrial seed oils: Soybean oil, canola oil, and other highly processed oils.
- Highly processed foods: Contain additives, preservatives, and artificial flavors.
- Excessive alcohol: Strains the liver and adds empty calories.
Visualizing the Pyramid
- Base (Largest): Meat, fish, eggs, and natural fats.
- Middle Layers: Low-carb vegetables and moderate portions of seasonal fruits or tubers.
- Top (Smallest): Nuts, seeds, and fermented foods.
Additional Principles
- Hydration: Prioritize water, with herbal teas and coffee in moderation. Avoid sugary drinks.
- Seasonal and Local Eating: Focus on fresh, unprocessed, and locally available foods, as they are likely to be more nutrient-dense.
- Intermittent Eating: Mimic ancestral patterns of eating, which may have included intermittent fasting due to inconsistent food availability.
