The nutritional profile of milk is impressive. After all, it is designed to fully nourish new-born animals. Just one cup (244 grams) of whole cow’s milk contains,

• Calories: 146
• Protein: 8 grams
• Fat: 8 grams
• Calcium: 28% of the RDA
• Vitamin D: 24% of the RDA
• Riboflavin (B2): 26% of the RDA
• Vitamin B12: 18% of the RDA
• Potassium: 10% of the RDA
• Phosphorus: 22% of the RDA
• Selenium: 13% of the RDA

Milk is an excellent source of vitamins and minerals, including “nutrients of concern,” which are under-consumed by many populations. It provides potassium, B12, calcium and vitamin D, which are lacking in many diets.

Milk is also a good source of vitamin A, magnesium, zinc and thiamine (B1). Additionally, it’s an excellent source of protein and contains hundreds of different fatty acids, including conjugated linoleic acid (CLA) and omega-3s.

Conjugated linoleic acid and omega-3 fatty acids are linked to many health benefits, including a reduced risk of diabetes and heart disease. The nutritional content of milk varies, depending on factors like its fat content and the diet and treatment of the cow it came from. For example, milk from cows that eat mostly grass contains significantly higher amounts of conjugated linoleic acid and omega-3 fatty acids.

Also, organic and grass-fed cow’s milk contains higher amounts of beneficial antioxidants, such as vitamin E and beta-carotene, which help reduce inflammation and fight oxidative stress (12Trusted Source).

Summary Milk contains a wide array of nutrients, including vitamins, minerals, protein, healthy fats, and antioxidants.

Milk is a rich source of protein, with just one cup containing 8 grams. Protein is necessary for many vital functions in your body, including growth and development, cellular repair and immune system regulation.

Milk is considered a “complete protein,” meaning it contains all nine of the essential amino acids necessary for your body to function at an optimal level. There are two main types of protein found in milk casein and whey protein. Both are considered high-quality proteins. Casein makes up most of the protein found in cow’s milk, comprising 70–80% of the total protein content. Whey accounts for around 20%. Whey protein contains the branched-chain amino acids leucine, isoleucine, and valine, all of which are linked to health benefits.

Branched-chain amino acids may be particularly helpful in building muscle, preventing muscle loss and providing fuel during exercise. Drinking milk is associated with a lower risk of age-related muscle loss in several studies. In fact, higher consumption of milk and milk products has been linked to greater whole-body muscle mass and better physical performance in older adults. Milk has also been shown to boost muscle repair in athletes.

In fact, several studies have demonstrated that drinking milk after a workout can decrease muscle damage, promote muscle repair, increase strength, and even decrease muscle soreness. Plus, it is a natural alternative to highly processed protein drinks marketed toward post-workout recovery.

Summary Milk is a rich source of quality protein that contains all nine essential amino acids. It may help reduce age-related muscle loss and promote muscle repair after exercise.

Drinking milk has long been associated with healthy bones. This is due to its powerful combination of nutrients, including calcium, phosphorus, potassium, protein and (in grass-fed, full-fat dairy) vitamin K2. All these nutrients are essential for maintaining bones. Approximately 99% of your body’s calcium is stored in your bones and teeth.

Milk is an excellent source of the nutrients your body relies on to properly absorb calcium, including vitamin D, vitamin K, phosphorus, and magnesium. Adding milk and dairy products to your diet may prevent bone diseases like osteoporosis. Studies have linked milk and dairy to a lower risk of osteoporosis and fractures, especially in older adults.

What is more, milk is a good source of protein, a key nutrient for bone health. In fact, protein makes up about 50% of bone volume and around one-third of bone mass. Evidence suggests that eating more protein may protect against bone loss, especially in women who do not consume enough dietary calcium.

Summary Milk contains a variety of nutrients that benefit bone health, such as calcium, vitamin D, phosphorus, and magnesium. Studies suggest that consuming milk and dairy products may prevent osteoporosis and reduce the risk of fractures.

Several studies have linked milk intake to a lower risk of obesity. Interestingly, this benefit has only been associated with whole milk. A study in 145 three-year-old Latino children found that higher milk-fat consumption was associated with a lower risk of childhood obesity.

Another study including over 18,000 middle-aged and elderly women showed that eating more high-fat dairy products was associated with less weight gain and a lower risk of obesity.

Milk contains a variety of components that may contribute to weight loss and prevent weight gain. For example, its high-protein content helps you feel full for a longer period, which may prevent overeating. Furthermore, the conjugated linoleic acid in milk has been studied for its ability to boost weight loss by promoting fat breakdown and inhibiting fat production.

Additionally, many studies have associated diets rich in calcium with a lower risk of obesity. Evidence suggests that people with a higher intake of dietary calcium have a lower risk of being overweight or obese. Studies have shown that high levels of dietary calcium promote fat breakdown and inhibit fat absorption in the body.

Summary Adding milk, especially whole milk, to your diet may prevent weight gain.

Milk is a nutritious beverage that provides several health benefits. Moreover, it is a versatile ingredient that can be easily added to your diet. Aside from drinking milk, try these ideas for incorporating it into your daily routine:

• Smoothies: It makes an excellent, high-protein base for healthy smoothies. Try combining it with greens and a small amount of fruit for a nutritious snack.
• Oatmeal: It provides a tasty, more nutritious alternative to water when making your morning oatmeal or hot cereal.
• Coffee: Adding it to your morning coffee or tea will give your beverage a boost of beneficial nutrients.
• Soups: Try adding it to your favourite soup recipe for added flavour and nutrition.

If you are not a fan of milk, there are other dairy products that have similar nutrient profiles. For example, unsweetened yogurt made from milk contains the same amount of protein, calcium, and phosphorus. Yogurt is a healthy and versatile alternative to processed dips and toppings.

SUMMARY Milk is a versatile ingredient that can be added to your diet in several ways. Try adding it to smoothies, coffee, or your morning oatmeal.
