Abstract: In this research effort, we compared nutritional parameters of this 2 kind milk such as total fat, fiber, protein, minerals (Ca, Fe and P), fatty acids, carbohydrate, lactose, water, total solids, ash, pH, acidity and calories content in one cup (245 g). Results showed soymilk contains 4.67 g of fat, 0.52 of fatty acids, 3.18 of fiber, 6.73 of protein, 4.43 of carbohydrate, 0.00 of lactose, 228.51 of water, 10.40 of total solids and 0.66 of ash, also 9.80 mg of Ca, 1.42 of Fe and 120.05 of P, 79 Kcal of calories, pH = 6.74 and acidity was 0.24%. Cow milk contains 8.15 g of fat, 5.07 of fatty acids, 0.00 of fiber, 8.02 of protein, 11.37 of carbohydrate, 4.27 of lactose, 214.69 of water, 12.90 of total solids, 1.75 of ash, 290.36 mg of Ca, 0.12 of Fe and 226.92 of P, 150 Kcal of calories, pH = 6.90 and acidity was 0.21%. Soy milk is one of plant-based complete proteins and cow milk is a rich source of nutrients as well. Cow milk is containing near twice as much fat as and 10 times more fatty acids do soymilk. Cow milk contains greater amounts of mineral (except Fe) it contain more than 300 times the amount of Ca and nearly twice the amount of P as does soymilk but soymilk contains more Fe (10 time more) than does cow milk. Cow milk and soy milk contain nearly identical amounts of protein and water and fiber is a big plus, dairy has none. Although, what we choose to drink is really a mater of personal preference and our health objectives but looking at the comparison, soy looks like healthier choices.
