Milk is one of the most common foods, but also one of the most controversial.
Should you drink it because it keeps your bones strong, or shun it because it has been tied to everything from heart disease to cancer? Here's our guide to milk, and its impact on your health.
It's a good source of calcium
The debate about milk is closely tied to its nutritional benefits as a key source of the mineral calcium, which is responsible for strong bones. If your body lacks calcium, you may get brittle bones disease osteoporosis. Calcium also plays a role in blood clotting, the transmission of nerve impulses, and regulating the heart's rhythm. Dairy products are considered a good source of calcium because they have the highest concentration of highly absorbable calcium per serving.
That said, milk is not the only source of calcium. You can get calcium from dark leafy greens or dried beans. In fact, you can also get calcium from supplements which, when coupled with vitamin D, are very effective in protecting your bone health. So are there any good reasons to drink milk if you can get the calcium from other sources?
Benefits of milk. 
In short, yes. When consumed in moderation, milk and the calcium it delivers to the body has a positive effect on your body beyond strengthening your bones. Studies have tied it to possibly lowering the risk of high blood pressure, though the benefits appear quite limited. Milk has also been found to lower your risk of developing colon cancer. This benefit comes from drinking just one to two glasses of milk daily, as well as having a balanced diet. Drinking more does not appear to lower the risk further. But drinking too much milk can also be problematic.

When milk is not good for you.
Some people cannot tolerate lactose, which is a key ingredient of milk. If you have this intolerance, milk can make you bloated and gassy, and give you cramps and diarrhoea.
Full fat milk is high in saturated fats, which increase your risk of developing heart disease. If you drink low fat milk, you should make sure you're not getting saturated fats from eating too much butter and ice cream.
Research into high milk consumption - 3 cups or more daily - has actually been tied to a slightly higher risk of ovarian cancer. This is believed to be caused by high levels of galactose, a sugar released when your body digests the lactose in milk, damaging the ovaries. A high calcium diet has also been implicated as a probable risk factor for prostate cancer. A recent study found that men who drank two or more glasses of milk a day had nearly double the risk of developing fatal prostate cancer as those who had the lowest intake.
Should I drink milk or not?
overindulge in dairy products.

If you grew up drinking plenty of milk, your bones should be in good shape. Do not feel like you should give up your daily glass of milk, or bowl of cereal. Milk is an excellent source of calcium, but be aware that there is no good evidence that having more than one serving a day will reduce your risk of bone fracture. Given the concerns about ovarian and prostate cancer, it may be a good idea to not
