Drinking milk with breakfast may help control blood sugar levels, study finds

A recent study has found that drinking a glass of milk with breakfast can help lower blood glucose levels throughout the day.

Researchers observed that when milk is consumed alongside common breakfast cereals like cornflakes, it significantly reduces post-meal (postprandial) blood sugar spikes.

The effect was even more noticeable when milk was paired with protein-rich breakfasts, such as eggs. According to the findings, this combination helps maintain stable blood glucose levels for several hours after eating.

The key component behind this benefit is casein—a high-quality protein found in milk. Casein is rich in essential amino acids, many of which support muscle strength and overall metabolic health.

Beyond its protein content, a single glass of milk also supplies most of the calcium needed by the body for the entire day. It’s also a reliable source of vitamin D, a nutrient that is increasingly lacking in both children and the elderly.

The study adds to growing evidence supporting milk as a valuable part of a healthy breakfast, especially for those looking to manage blood sugar levels more effectively.
