What cows are fed makes a big difference in milk quality. During warmer months, when cows are free to graze, the good fats in milk get even better. For example, CLA is 60% higher in milk from grazing cows. Women who eat organic dairy have 50% more CLA in their breast milk than those who don’t [42]. CLA is a healthy fat that helps reduce body fat and maintain muscle mass.* CLA is popular as a weight loss supplement. However, the organic, natural version is superior to synthetic supplements.
