Milk is a better alternative to fruit juices for breakfast. But try and opt for organic milk as it has more Vitamin E and omega-3 fatty acids as compared to its inorganic counterpart. However, you need not give up on fruit juices entirely.
But gulp them down instead of having them sip by sip, so that the duration for which the juice is in touch with your teeth is short.
This prevents the corrosive effect of juice while not depriving you of its nutritional benefits. There are studies that have shown that people who drink milk in the morning are less likely to indulge in in-between meal snacking or overeating during lunch.
1 glass of milk contains about 20% of proteins that you need in a day. And drinking milk in the morning makes us feel full because of the satisfying nature of the protein.
Also, milk contains calcium that regulates weight controlling hormones in the body.
