English
The glycemic index (GI) is a ranking system for carbohydrates based on their effect on blood glucose levels. Foods are classified on a scale from 0 to 100, with pure glucose having a GI of 100. Foods with a high GI are rapidly digested and absorbed, resulting in a swift increase in blood sugar levels. In contrast, foods with a low GI are digested and absorbed more slowly, leading to a gradual rise in blood sugar levels. Understanding the GI of different foods can be crucial for managing conditions like diabetes and for maintaining overall health.
Milk and dairy products are essential components of many diets worldwide, providing valuable nutrients such as calcium, protein, and vitamins. However, their carbohydrate content and subsequent impact on blood sugar levels can vary significantly. This blog will explore the glycemic index of milk and dairy products, helping you make informed choices about their consumption.
Milk and Glycemic Index
The glycemic index (GI) is a scale that measures how quickly carbohydrates in food raise blood sugar levels after consumption. Milk, being a rich source of carbohydrates in the form of lactose (a natural sugar), has a specific glycemic index that varies depending on its type and fat content. The glycemic index of milk is influenced by several factors, including the presence of lactose, fat, and protein.
Explaining milk and glycemic index, whole milk has a moderate GI due to its balanced content of fat, protein, and carbohydrates, which slows down the absorption of sugars into the bloodstream. Reduced fat and skim milk, while lower in fat, generally have a similar GI because the reduction in fat is balanced by the remaining protein and lactose content.
On the other hand, plant-based milks, such as almond or soy milk, often have a lower GI compared to cow’s milk due to their different carbohydrate profiles and higher fiber content. Sweetened or flavored milks typically have a higher GI due to added sugars.
Understanding the GI of milk is crucial for managing blood sugar levels, especially for individuals with diabetes. Choosing milk with a lower GI can help maintain more stable blood glucose levels, providing sustained energy and reducing the risk of blood sugar spikes.

Glycemic Index of Different Types of Milk
Glycemic Index of Cow Milk
Cow’s milk is a staple in many households and comes in various fat contents: whole, reduced-fat, low-fat, and skim milk. The carbohydrate content in milk primarily comes from lactose, a natural sugar. When it comes to milk and glycemic index, cow milk can be your go-to. The glycemic index of cow milk can vary slightly based on its fat content:
- Whole Milk (GI: 41)
- Reduced-Fat Milk (GI: 34)
- Low-Fat Milk (GI: 37)
- Skim Milk (GI: 37)
Goat’s Milk Glycemic Index
Goat’s milk is an alternative to cow’s milk and is often easier to digest for some people. It has a slightly lower GI than cow’s milk:
- Goat’s Milk (GI: 30)
Plant-Based Milks Glycemic Index
Plant-based milks are popular alternatives for those who are lactose intolerant or follow a vegan diet. The GI of these milks can vary widely depending on their ingredients and added sugars:
- Soy Milk (unsweetened) (GI: 34)
- Almond Milk (unsweetened) (GI: 25)
- Rice Milk (GI: 86)
- Coconut Milk (GI: 31)
- Oat Milk (GI: 69)
Buffalo Milk Glycemic Index:
Buffalo milk is commonly consumed in many parts of the world, especially in South Asia. It is known for its high fat and protein content compared to cow’s milk. Buffalo milk glycemic index can also vary based on its fat content:
- Whole Buffalo Milk (GI: 30)
- Reduced-Fat Buffalo Milk (GI: 28)
- Low-Fat Buffalo Milk (GI: 27)
- Skim Buffalo Milk (GI: 27)
Almond Milk Glycemic Index
Almond milk is a popular plant-based alternative to cow’s milk, especially among those who are lactose intolerant or follow a vegan diet. It is known for its low carbohydrate content and high levels of healthy fats and vitamins. Almond milk’s glycemic index can vary depending on whether it is sweetened or unsweetened:
- Unsweetened Almond Milk (GI: 25)
- Sweetened Almond Milk (GI: 50)
- Flavored Almond Milk (GI: 40-60)
Glycemic Index of Dairy Products
Yogurt
Yogurt is a fermented dairy product with a variable GI depending on whether it is sweetened or plain. The presence of live cultures in yogurt can also impact its glycemic response:
- Plain Yogurt (GI: 14)
- Sweetened Yogurt (GI: 36)
- Greek Yogurt (GI: 11-14)
Cheese
Cheese has minimal carbohydrate content, and thus its GI is typically very low or negligible. However, it is important to consider portion sizes and fat content:
- Cheddar Cheese (GI: 0)
- Cottage Cheese (GI: 10)
- Mozzarella (GI: 0)
- Feta Cheese (GI: 0)
Butter and Cream
Butter and cream are high-fat dairy products with little to no carbohydrate content, meaning their GI is negligible:
- Butter (GI: 0)
- Heavy Cream (GI: 0)

Factors Affecting the Glycemic Index of Milk and Dairy Products
Several factors can influence the glycemic index of milk and dairy products, including:
Fat Content: Higher fat content can slow the absorption of carbohydrates, leading to a lower GI.
Processing and Additives: Sweetened and flavored dairy products typically have a higher GI due to added sugars.
Fermentation: Fermented dairy products like yogurt and kefir tend to have a lower GI due to the presence of beneficial bacteria that aid in digestion.
Individual Variability: Personal metabolic responses can vary, affecting how quickly blood sugar levels rise after consuming dairy products.

Benefits of Low GI Dairy Products
Incorporating low-GI dairy products into your diet can offer several health benefits, especially for those managing diabetes or looking to maintain steady blood sugar levels:
Improved Blood Sugar Control: Low GI foods can help maintain more stable blood sugar levels, reducing the risk of spikes and crashes.
Satiety and Weight Management: Low GI foods often promote a feeling of fullness, which can aid in weight management by reducing overall calorie intake.
Nutrient-Rich: Many low-GI dairy products are rich in essential nutrients like calcium, protein, and vitamins, contributing to overall health.
Practical Tips for Choosing Low GI Dairy Products
Opt for Plain or Unsweetened Varieties: Choose plain or unsweetened versions of yogurt, milk, and other dairy products to avoid added sugars.
Read Labels: Check nutrition labels for carbohydrate content and added sugars, which can influence the GI.
Combine with Other Foods: Pair dairy products with high-fiber foods like fruits, vegetables, or whole grains to help lower the overall glycemic response of your meal.
Moderate Portions: Even low GI foods can impact blood sugar levels if consumed in large quantities, so be mindful of portion sizes.
