Milk does contain small amounts of antioxidants like glutathione and lactoferrin, but their levels are relatively low compared to other dietary sources. If you’re looking to boost your antioxidant intake, prioritize a colorful diet filled with berries, leafy greens, beans, and nuts alongside your daily glass of milk.

What is lactose intolerance?

Understanding Lactose Intolerance: Lactose intolerance is a common condition where the body lacks sufficient lactase, the enzyme responsible for breaking down lactose, a sugar found in milk and other dairy products. This digestive issue occurs when the small intestine does not produce enough lactase, making it difficult for the body to digest lactose, leading to uncomfortable symptoms such as bloating, gas, diarrhea, and stomach cramps. People with lactose intolerance may experience varying levels of discomfort, and symptoms can range from mild to severe. Those with lactose intolerance are not allergic to milk, but rather, they require lactase supplements or choose lactose-free dairy products to alleviate symptoms. Additionally, individuals with lactose intolerance can also consider alternative sources of calcium, such as fortified plant-based milk options, dark leafy greens, and almonds, thereby continuing to meet their nutritional needs while minimizing discomfort.

Can milk be fortified with additional nutrients?

Milk is an excellent source of essential nutrients, including protein, calcium, and vitamins D and B12. However, it can be further fortified with additional nutrients to enhance its nutritional profile and meet the diverse needs of various populations. For instance, milk can be fortified with vitamin D and calcium to support bone health and reduce the risk of osteoporosis, particularly in older adults. Additionally, milk can be enriched with omega-3 fatty acids, which can support heart health and brain function. Some milk alternatives, such as soy milk and almond milk, can even be fortified with plant-based isoforms of nutrients like protein and calcium. Fortifying milk with additional nutrients can also help address specific nutritional deficiencies, such as vitamin B12 deficiency, which is common in vegetarians and vegans.
