Have you ever wondered why humans began cooking their food? Why do we go through the effort to chop, ferment, salt, and dry ingredients instead of just eating everything raw? It turns out these practices aren’t just about flavor or tradition, they’re rooted in biology, digestion, and survival. Cooking isn’t simply a culinary preference, it’s a key to human evolution and modern health.

Cooking Increases Digestibility and Nutrient Absorption

When you cook starches (think potatoes, grains, legumes), their complex carbohydrates break down, making them easier for the body to digest and convert into usable energy. Similarly, cooking meats breaks down connective tissue and denatures proteins, making them easier to chew and digest.

As early humans began cooking food, they were able to extract more calories and nutrients, leading to major evolutionary leaps, including brain growth and physical development.

This isn’t just a theory, it was proven through early scientific observation. U.S. Army surgeon Dr. William Beaumont conducted experiments in the 1800s that revealed cooked food digested far more efficiently than raw food. His research helped lay the foundation for understanding human digestion.

The Raw Food Diet: A Cautionary Tale

While raw food diets have gained popularity in wellness circles, they come with real risks. A study on individuals following strict raw food diets showed significant weight loss, but not necessarily in a healthy way. Many participants experienced nutritional deficiencies and disruptions in hormonal function, especially women whose reproductive health was impacted due to low body fat and caloric intake. That’s not to say raw foods should be avoided altogether. Raw fruits, vegetables, nuts, and seeds are incredibly beneficial, but balance and preparation methods are key.

Fermentation, Salting, Drying: More Than Preservation

Long before refrigeration, humans discovered that fermentation, salting, and drying not only preserved food but made it more digestible and even more nutritious. Fermented foods like kimchi, sauerkraut, and yogurt support gut health, while salting and drying can enhance flavor and shelf stability without relying on modern preservatives. These traditional food preparation techniques reflect generations of nutritional wisdom, grounded in supporting the microbiome, regulating metabolism, and aiding digestion.

Lifestyle Changes Matter More Than Diet Trends

Here’s the big picture: true health doesn’t come from rigid diet trends. It comes from sustainable lifestyle changes that improve digestion, balance hormones, and support metabolism.

Cooking at home, preparing whole foods, and including a variety of textures and preparations (raw, cooked, fermented, etc.) can help you:

  • Maintain a healthy weight

  • Avoid blood sugar spikes

  • Reduce bloating and inflammation

  • Support long-term satiety and energy

  • Improve gut-brain connection

If you’re struggling with weight loss, or digestion, or just feel overwhelmed by nutrition advice, don’t go it alone. A personalized plan makes all the difference.
