What Is Lactose Intolerance

Lactose intolerance is a very common digestive problem. In fact, it affects around 75% of the worlds population .

Interestingly, its most prevalent in Asia and South America, but much less common in parts of the Western world like North America, Europe and Australia .

Those who have it dont have enough of an enzyme called lactase. Produced in your gut, lactase is needed to break down lactose, the main sugar found in milk.

Without lactase, lactose can pass through your gut undigested and cause unpleasant symptoms like nausea, pain, gas, bloating and diarrhea .

Fear of developing these symptoms can lead people with this condition to avoid foods that contain lactose, such as dairy products.

However, this isnt always necessary, as not all dairy foods contain enough lactose to cause problems for people with an intolerance.

In fact, its thought that many people with an intolerance can eat up to 12 grams of lactose at a time without experiencing any symptoms .

To put that in perspective, 12 grams is the amount found in 1 cup of milk.

Additionally, some dairy foods are naturally low in lactose. Below are 6 of them.

Why Is Whey Protein Problematic For Lactose Intolerance

Which milk alternative should we be drinking?

Whey protein is derived from milk. If youre lactose intolerant and you take whey protein, its pretty likely that you will experience the same symptoms as if you would drink milk or eat other high lactose foods.

When youre lactose intolerant and consume anything high in lactose like whey, it doesnt break down for absorption as it should. Once that unprocessed lactose gets into the colon, it reacts with bacteria and causes gas, bloating, and diarrhea. Some people also experience nausea or allergic reactions like hives and a runny nose.

Although these symptoms arent usually harmful, theyre definitely uncomfortable and interfere with your daily life. Discomfort may negatively impact your workouts, and bloating can mask your progress.

Im Allergic To Dairy Is Lactose

If you have a dairy allergy, your body is reacting to the proteins in milk, not the lactose. Lactose-free milk still contains milk casein and whey proteins, so if you have a diagnosed dairy allergy, lactose-free milk will still cause an allergic reaction. If you are sensitive to dairy, we recommend consulting with your health care provider before trying lactose-free milk.

Differences Between The Pathologies

Clinical manifestations of milk protein allergy related to the digestive tract are very similar to those of lactose intolerance, which can easily lead to misdiagnosis. However, CMPA can cause skin lesions and also respiratory symptoms, which does not occur in lactose intolerance. Lactose intolerance, in turn, is purely a matter of digestion and absorption, with no immunologic mechanism involved in the pathophysiology, and it affects adults more frequently than children. Its evolution can be transient or definitive . Como conceituar, diagnosticar e tratar a intolerância à lactose. Revista Brasileira de Clínica e Terapêutica, 34, 13-20.). The difference of the characteristics between these two pathologies is described in Table 4.

The 411 On The Difference Between Lactose Free And Dairy Free

There are a variety of non-dairy milks and products ranging from cheese to ice cream to yogurt available at most mainstream supermarkets. Depending on your reasons for choosing them in place of conventional cows milk, you may need a refresher on the difference between dairy free and lactose free products to ensure you are selecting the products that are best for you.

Lactose free products are beneficial for people suffering from lactose intolerance. Lactose intolerance is very common, especially in adults. According to the U.S. National Library of Medicine, about 30 million Americans have some degree of lactose intolerance by the age of 20. Lactose is a type of sugar found in milk products. In order to digest lactose properly, the body produces an enzyme called lactase. In people with lactose intolerance, the body stops producing adequate amounts of lactase, causing symptoms such as bloating, gas, cramps, diarrhea and nausea. Individuals with lactose intolerance may find they are able to eat small amounts of products that contain lactose without experiencing symptoms. Sometimes, they may also be able to tolerate products such as yogurt or goats milk more easily than cows milk. Lactase tablets are also available for lactose intolerant individuals to help them digest lactose. People with lactose intolerance can eat foods that contain casein and whey, which are milk proteins, not sugars.


How Much Protein Is In A Cup Of Milk

  • Article

Milk is a good , with 8 grams in a cupor about 1 gram of protein per ounce.

This is true whether you choose fat-free, low-fat, lactose-free or whole milk. Each contain high-quality protein, which means they provide all the essential amino acids your body cant make on its own.

Milk contains two types of protein: casein and whey. Both occur naturally in milk, and the powder form of whey can be mixed in with other foods to boost protein content.

Whey is considered a fast protein because it is digested faster so it releases amino acids to the muscle more quickly than casein does. That might be why so many athletes choose chocolate milk as a recovery drink!

Casein has its place too, however. Some scientists think taking it before bed helps maximize the repair and rebuilding of our muscles as we sleep, because it is digested slower and releases amino acids at a slower rate over time than whey.

No matter when you have it, protein helps bodies rebuild and maintain tissues like those in our muscular and nervous systems. When we get enough protein throughout the day, we likely dont need to rely much on our bodys stores.

Research shows getting 10 to 15 grams of essential amino acids per meal, including 2 to 3 grams of leucine, which is also found in milk, can help rebuild muscle.

Whey Protein And Lactose Intolerance: Can You Drink It

Lactose intolerance is a digestive disorder caused by the inability to digest the main carbohydrate in dairy products: lactose.

If you have lactose intolerance, that means you dont make enough of the enzyme lactase. Lactase is needed to digest lactose. This lactase enzyme breaks lactose down into glucose and galactose so your body can use these simple sugars for energy. But without sufficient lactase, lactose moves through your gut undigested. When lactose isnt digested, you may begin to experience symptoms like bloating, diarrhea and abdominal pain.

Lactose intolerance can limit the foods you consume. Lactose-containing foods that may need to be avoided depending on the degree of your sensitivity include milk products like ice cream, cheese, milk chocolates or yogurt milk solids or milk powders creams, buttermilk and curds.

But what about the not-so-obvious offenders? Did you know foods like bread and baked goods, salad dressings, sauces, soups, breakfast cereals and cheese-flavored snacks can contain lactose in small quantities and could possibly upset your stomach?

If you know or suspect you have lactose intolerance, it is important to be mindful of what foods in your diet could be triggering to stomach upset including your protein shakes.

Can I Consume Whey Protein If I Am Lactose Intolerant

Whether or not you can consume whey protein if you are lactose intolerant will depend on a variety of factors.

First, it will depend on the severity of your lactose intolerance and how significant your reaction is when consuming lactose. People who experience mild discomfort unless they eat large quantities of dairy products may not be bothered by the relatively small amount of lactose found in whey protein, while those with a stronger reaction may not be able to digest whey protein.

The other factor involved is the type of whey protein that is being consumed, as each type of whey protein contains a different amount of lactose. Whey protein concentrate has the highest amount of lactose of any of the types of whey protein, while whey protein isolate contains significantly less and hydrolysate contains even less than whey protein isolate.

Therefore, people with lactose intolerance are more likely to be able to digest whey protein isolate or hydrolysate than whey protein concentrate, but every persons experience will be different depending on the severity of their condition.

Can I Build Muscle With Dairy

Ultimately, you can build muscle using virtually any kind of protein supplement, but none are quite as efficient as whey . Plant-based protein powders, while useful, are not optimal. A 2019 review in Nutrients reported that plant-based proteins have less of an anabolic effect than animal proteins due to their lower digestibility, lower essential amino acid content , and deficiency in other essential amino acids. Theyre more likely to be oxidized, the review states, than used for muscle protein synthesis .

Another 2015 review of animal and plant-based proteins published in the Journal of Nutrition echoes these points, explaining that proteins in soy and wheat are converted into urea , and cant be utilized by the body as easily as animal proteins can to promote muscle growth.

With that said, plant proteins have been shown to be effective for supporting muscle gain. Soy is the most thoroughly studied plant-based protein, and its widely available. Much research has shown that it can nearly match whey on many fronts. However, it has also been shown to lower the bodys absorption of iron and zinc . In addition, soy has been criticized because it can bind to the estrogen receptors in the body. This impacts hormones levels, making it one of the more controversial plant-based proteins, according to research from the Harvard School of Public Health.
