Fresh milk is a nutritious drink, but the amount of natural lactose in milk can affect blood sugar after drinking. However, the level of impact on blood sugar depends on the type of milk, amount used and metabolism of each person.
The impact of fresh milk on blood sugar levels
Pure fresh milk usually has a low glycemic index (GI), ranging from 31 to 39. Thanks to its rich protein content, depending on the type of milk, fat can contribute to slowing down blood sugar response compared to some sugary drinks. However, if you consume too many carbohydrates from milk, your glycemic index can still increase.

Suggestions for choosing milk to support blood sugar stabilization
To supplement safe nutrition, users should prioritize the following products:
Unsweetened fresh milk: Does not contain added sugar, is rich in calcium and protein, can help create a feeling of fullness for a long time and is good for people who need to control blood sugar.
Skim milk (low fat): Suitable for people at risk of cardiovascular disease or dyslipidemia. Users need to carefully read the ingredient list to avoid products with added artificial sweeteners.
Unsweetened nut milk: Provides good fats and antioxidants, is an effective alternative to support cardiovascular health.

Note the time of use
Drinking a large amount of milk at the same time or in combination with sweets and starches quickly absorbed can increase the total amount of carbohydrates ingested, which is detrimental to blood sugar control. Therefore, patients should divide the amount of milk into smaller portions and combine a scientific diet.
