Goat Milk vs Cow Milk: Which Is a Better Choice for People With Diabetes?

Goat Milk vs Cow Milk: Which Is a Better Choice for People With Diabetes?

Standing in front of the dairy section of the store or in the supermarket can be a confusing experience for someone with diabetes or prediabetes. You want to easily grab something to add to your morning tea or bowl of oats, but you also have to think about how much it will affect your blood sugar levels. Many people wonder if it is a better choice to switch to goat milk.

Both cow milk and goat milk provide good sources of nutrients, such as calcium to help keep your bones healthy and protein to keep you feeling full. However, both contain natural milk sugars that will increase your blood sugar.

The Kenya National Clinical Guidelines for Management of Diabetes Mellitus state that you do not have to avoid milk while managing diabetes, though you should be mindful of the amount you consume, the fat content, and how many carbohydrates it contains (Kenya Ministry of Health). The American Diabetes Association (ADA) also advises that you can safely include milk in your meal plan.

Comparing the two will help you decide which is best to keep in your kitchen.

What Is in Your Cup?

Comparing the nutritional information of the two milks using the Kenya Food Composition Tables (published by the Kenya Ministry of Health and the Food and Agriculture Organization) and the U.S. Department of Agriculture (USDA) FoodData Central shows they are both good sources of nutrition. However, goat milk contains slightly more calories, fat, and protein.

One 8-ounce cup of plain milk provides:

• Natural Sugars (Lactose): Whole goat milk contains around 11 grams of carbohydrates, while whole cow milk contains around 12 grams.

• Protein: Goat milk contains around 9 grams of protein, whereas cow milk contains 8 grams.

• Fat and Calories: Whole goat milk contains around 10 grams of fat and 168 calories, while whole cow milk contains around 8 grams of fat and 149 calories.

• Vitamins and Minerals: Research by food scientists at Jomo Kenyatta University of Agriculture and Technology (JKUAT) and Dedan Kimathi University of Technology shows that goat milk contains more calcium, potassium, vitamin A, and vitamin B6, while cow milk contains more vitamin B12 and folate.

Blood Sugar Reaction

Because both milks contain lactose (a natural sugar), neither is carb-free. However, both rank low on the glycemic index (GI). Plain milk usually scores between 24 and 39, meaning it releases sugar into your blood slowly (University of Sydney Glycemic Index Research Service).

Dietitians have stated that the fat and protein contents cause your stomach to empty more slowly, which keeps your blood sugar levels stable (Verywell Health). Milk proteins also help your body release insulin properly (Archives of Internal Medicine).

Benefits of Goat Milk

Goat milk has several benefits that make it a good option for those looking to control their blood sugar:

• Easier on the Stomach: Studies by the Kenya Agricultural and Livestock Research Organization (KALRO) and JKUAT confirm that goat milk contains much smaller fat globules. Combined with having around 1 gram less sugar per cup, many people find it lighter and easier to digest.

• Good for Gut Bacteria: Goat milk contains natural prebiotic fibers that support beneficial bacteria in your gut, helping keep your metabolism healthy (Current Developments in Nutrition).

• Early Research: Studies in Molecular Nutrition & Food Research showed that goat milk helped improve fasting blood sugar in diabetic mice. However, endocrinologists note that large human studies are limited, so goat milk should not be used as a medical treatment.

Why Cow Milk Is a Good Option for Many

Despite goat milk's benefits, many people with diabetes find it easiest to use regular cow milk:

• Easy to Find Low-Fat Options: Whole goat milk contains quite a lot of saturated fat. Because diabetes increases your risk of heart problems, the Kenya Ministry of Health, the American Heart Association (AHA), and the Centers for Disease Control and Prevention (CDC) advise choosing low-fat or fat-free milk most of the time. Low-fat cow milk is easy to find at most shops, whereas low-fat goat milk can be difficult to find.

• More Affordable and Fortified: Cow milk is usually cheaper and is sold everywhere in Kenya. Most packaged cow milk also contains added vitamin D, which helps support insulin health (National Institutes of Health).

Which Milk to Choose?

Both milks can be enjoyed in small amounts. If you want slightly fewer carbohydrates per cup or find cow milk difficult to digest, plain goat milk is a great option. If you want less saturated fat, lower grocery costs, or more vitamin D, low-fat cow milk is usually the better choice.

No matter which milk you choose, avoid flavored or sweetened varieties. Stick to one 8-ounce cup and pair it with high-fiber foods, such as plain rolled oats or chia seeds, to keep your blood sugar levels stable (Mayo Clinic and Kenya National Clinical Guidelines for Management of Diabetes Mellitus).
