Is soy milk better at calcium supplementation than raw milk?
A. No
B. Absolutely
Correct Answer: No
Answer Analysis:
Soy milk and milk are both good sources of calcium, but they have some differences in their calcium supplementation effects.
First of all, the calcium content in milk is usually higher than that of soy milk. Milk contains about 120 mg of calcium per 100 grams, while the same amount of soy milk contains about 20-30 mg of calcium. However, the absorption rate of calcium is also important. The calcium absorption rate in soy milk is about 50%-60%, while the calcium absorption rate in milk is 30%-40%. This means that although soy milk has a lower calcium content, the body absorbs and utilizes it more.
Secondly, factors that affect calcium absorption include vitamin D and lactose. Milk naturally contains lactose, which aids in calcium absorption. However, lactose intolerant people have difficulty digesting lactose, which can affect calcium absorption. Soy milk is lactose-free and suitable for lactose intolerant people. However, the lack of vitamin D in soy milk may affect calcium absorption.
In addition, there are differences in the nutritional content of soy milk and milk. Soy milk contains soy isoflavones, which are good for bone health, but it also contains oxalic and phytic acids, which affect calcium absorption. Whereas, milk contains more protein and fat.
In summary, the calcium supplementation effect of soy milk and milk has its own advantages and disadvantages. For the average person, milk is a better choice. But for lactose intolerant or vegetarians, calcium-rich soy milk is a more suitable source of calcium. Maintain a balanced diet and moderate intake, the two can complement each other.
