Antinutrients, naturally present in plant-based foods, can significantly hinder the bioavailability and absorption of essential nutrients such as iron, calcium, and zinc. These compounds include phytates, oxalates, tannins, and lectins, among others. While they serve protective roles for plants, their consumption in excess or in unprocessed forms may impair human nutrition. This review highlights the pivotal role of consumer awareness in reducing the intake of dietary antinutrients and improving nutrient absorption. It emphasizes the necessity of educating populations about antinutrients, their effects, and traditional and modern food processing methods that reduce their concentration. Awareness campaigns and nutrition education programs have shown positive impacts on food choices and cooking practices, ultimately promoting better health outcomes. Enhanced knowledge can empower individuals to make informed dietary decisions, thereby mitigating the risk of malnutrition and micronutrient deficiencies.
