Extensive industrial processing of food has been associated with various adverse effects on the body, including appetite regulation, hormone balance, weight gain, and the risk of obesity and chronic diseases.
Highly processed foods, particularly those created through techniques like extrusion cooking, disrupt the internal structure or “food matrix” of ingredients, affecting nutrient availability, digestion, and satiety.
The production of ultra-processed foods often starts with fiber-rich grains that are milled and refined, leading to the removal of nutrient-rich components. Cooking extruders, widely used in the food industry, play a key role in mass-producing starchy and sugary packaged foods.
Extrusion cooking involves subjecting the mixture to heat, pressure, and rotating screws, which disrupt the food matrix and break down cell walls and glucose-containing granules.
Research suggests that extrusion cooking may accelerate the absorption of glucose and nutrients in the digestive tract, resulting in higher blood sugar and insulin levels.
Ultra-processed foods created through this process have been found to be less effective in satisfying hunger, and have a stronger impact on blood sugar levels compared to minimally processed foods.
Furthermore, ultra-processed foods are designed to be “hyper-palatable” by serving as vehicles for sugar, salt, fat, flavors, and additives. They are formulated to achieve a specific “bliss point,” triggering compulsive eating.
A study comparing diets of mostly ultra-processed foods and mostly homemade, unprocessed foods revealed that participants consumed significantly more calories on the ultra-processed diet, leading to weight gain and increased body fat.
This demonstrates that the level of food processing influences calorie intake and subsequent weight changes.
While cooking and food processing have long been part of human history, modern food technology has taken processing to a new level. Highly processed foods are efficiently absorbed, resulting in increased calorie absorption compared to fiber-rich, unprocessed diets.
These findings highlight the importance of considering the degree of food processing and opting for minimally processed, whole foods for better overall health. It is crucial to be aware of the impact of industrial processing and make informed choices for a healthier diet.
