Here are a few Health Benefits of Milk:

1. Bone Health

Milk comprises calcium, potassium, phosphorus, and Vitamin D; this combination promotes strong and healthy bones, muscle movement, and nerve signals. When kids drink milk daily, their bone health advances, and it also enhances proper growth. Adults can benefit from regular milk consumption along with Vitamin D to help prevent bone fractures, osteoarthritis, and osteoporosis (2). 99% of the calcium in your body is stored in bones. Since milk is rich in calcium, it aids in strengthening bones. So it is advisable to drink at least a glass of milk per day to prevent bone diseases (3). Genetics, physical activity, and proper calcium intake are the fundamental factors that contribute to healthy bones.

2. Heart Health

Potassium in milk helps to decrease blood pressure and dilate blood vessels. A combination of increased potassium intake and low sodium intake lowers blood pressure, which reduces the risk of heart disease and stroke. A huge quantity of saturated fat and cholesterol in cow’s milk can build the risk of heart disease, which is why people should eat dairy products in self-restraint. Thus we can keep blood pressure (4) and risk of cardiovascular diseases in check.

3. Cancer

Two nutrients in milk, calcium, and vitamin D help to protect against cancer. Milk contains calcium, which aids in protecting the gut lining that reduces the risk of rectum or colon cancer (5). However, research has connected an excessive amount of calcium with prostate cancer. Vitamin D plays a vital role in cell growth regulation, which might shield against breast cancer, colon, and prostate cancer. But research has connected too much vitamin D levels to the risk of pancreatic cancer. There are many factors that influence cancer risk.  So it is difficult to study cancer causes and risk factors.
