Lactose intolerance is a metabolic condition caused by insufficient lactase enzyme activity, leading to gastrointestinal discomfort upon consuming lactose-containing dairy products. To address this, lactose-free alternatives from both animal and plant sources have been developed. Plant-based milk alternatives, derived from cereals, legumes, nuts, seeds, and pseudo-cereals, offer a nutrient-rich, non-allergenic, and environmentally sustainable option. Oat milk is noted for its dietary fibers and cholesterol-lowering properties; soy milk is rich in high-quality protein and isoflavones; peanut milk contains significant antioxidants and essential nutrients; almond milk is praised for its healthy fats and vitamins; coconut milk offers unique antimicrobial properties; sesame milk boasts high-quality protein and lignans; hemp milk provides essential fatty acids; rice milk is a simple, nutrient-fortified option; cashew milk supports cardiovascular health; and macadamia milk is rich in omega fatty acids. Despite technological challenges and varying consumer acceptability due to taste and texture differences, plant-based milks are increasingly favored for their potential health benefits and environmental sustainability. However, these alternatives often require fortification to match the nutritional content of dairy milk, especially regarding protein, zinc, and potassium levels.
