体育投注网址By definition, it’s a nutrient-rich fluid that female mammals produce to feed their young.
The most commonly consumed types come from cows, sheep and goats.
Western countries drink cow’s milk most frequently.
体育投注网址Milk consumption is a hotly debated topic in the nutrition world, so you might wonder if it’s healthy or harmful.
体育投注网址Below are 5 science-backed health benefits of milk so you can decide if it’s the right choice for you.
The nutritional profile of milk is impressive.
体育投注网址After all, it’s designed to fully nourish newborn animals.
体育投注网址Just one cup (244 grams) of whole cow’s milk contains ():
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 (
体育投注网址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 (
Summary Milk contains a wide array of nutrients, including vitamins, minerals, protein, healthy fats and antioxidants. Keep in mind that its nutritional content can vary depending on many factors.
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 the majority 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 (
体育投注网址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’s 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 of these nutrients are essential for maintaining strong, healthy 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’s 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 of time, 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.
体育投注网址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 a number of health benefits.
Moreover, it’s 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:
If you’re 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体育投注网址 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 a number of ways. Try adding it to smoothies, coffee or your morning oatmeal.
Although milk may be a good choice for some, others can’t digest it or choose not to consume it.
Many people can’t tolerate milk because they’re unable to digest lactose, a sugar found in milk and dairy products.
Interestingly, lactose intolerance affects around 65% of the world’s population ().
体育投注网址Others choose not to consume milk or dairy products due to dietary restrictions, health concerns or ethical reasons.
This has led to a wide variety of nondairy milk alternatives, including:
体育投注网址When choosing a nondairy milk substitute, keep in mind that many of these products contain added ingredients like sweeteners, artificial flavors, preservatives and thickeners.
体育投注网址Choosing a product with limited ingredients is a good choice when comparing brands. Read the labels to determine which best suits your needs.
If possible, stick to unsweetened varieties to limit the amount of added sugar in your diet.
Summary There are many nondairy milk alternatives available for those who can’t or choose not to drink milk.
Milk is a nutrient-rich beverage that may benefit your health in several ways.
体育投注网址It’s packed with important nutrients like calcium, phosphorus, B vitamins, potassium and vitamin D. Plus, it’s an excellent source of protein.
体育投注网址Drinking milk and dairy products may prevent osteoporosis and bone fractures and even help you maintain a healthy weight.
体育投注网址Many people are unable to digest milk or choose to avoid it for personal reasons.
For those able to tolerate it, consuming high-quality milk and dairy products has been proven to provide a number of health benefits.
