Nutritional properties of goat milk vs cow’s milk
Property: fat (lipid) content
• Goat milk is higher in total fat.
• Goat milk is much higher in medium chain triglycerides (MCT), associated with numerous health benefits.
• Goat milk has a smaller fat globule size that enhances digestibility.
• Goat milk fat does not clump together, keeping it more homogenized and also aiding digestibility.
Property: protein content
• Goat milk contains more protein per serving.
• Goat milk contains higher levels of essential amino acids.
• Goat milk contains a percentage of proteins with different structures than cow’s milk proteins. These differences enhance the digestibility of goat milk protein, and cause fewer allergenic reactions.
• Goat milk contains a percentage of proteins with different structures than cow’s milk proteins. These differences enhance the digestibility of goat milk protein, and cause fewer allergenic reactions.
• Goat milk does not contain agglutinin like cow’s milk. Agglutinin is what makes the fat in cow’s milk separate from the other components.
• Goat milk contains much lower values, and in some cases, none, of the protein alpha-s1-casein. This protein promotes the formation of a hard curd from the milk, slowing digestibility. It is also a major allergen in cow’s milk.
Property: carbohydrates
• Goat milk has a lower carbohydrate level, almost all of which is due to less lactose in the milk. The inability to digest lactose is a common condition, and milk with less lactose is helpful for those individuals.
Property: vitamins
• Goat milk supplies more vitamin A. Vitamin A in goat milk is not in the form of beta-carotene as it is for cow’s milk. This different form of vitamin A is what makes goat milk whiter in color than cow’s milk.
• Goat milk supplies substantially more niacin (B3) and B6.
• Goat milk is lower in folic acid (B9) and B12.
• Goat milk has comparable amounts of the other vitamins.
Property: minerals
• Goat milk is higher in calcium.
• Goat milk is higher in phosphorous.
• Goat milk has substantially more potassium.
• Goat milk has more iron and copper.
• Goat milk has more magnesium.
• Goat milk has substantially more manganese.
• Selenium in goat milk has been shown to have more antioxidant activity.
• Goat milk has comparable levels of zinc and sodium.
