02 May 2023 — Swedish researchers found that using high- and medium-fat cow’s milk and coconut milk in spinach smoothies may make it easier to digest the antioxidant lutein from the leafy green. These liquids significantly improved lutein liberation – increasing the availability of the nutrient by releasing it from its food source.
Other drinks, such as soy milk, harmed the available lutein content of spinach smoothies compared to water.
