Whey is the liquid that remains after milk has been curdled and strained, and it contains lactose, vitamins, protein, and minerals. Historically, whey was considered a waste product, but it has since been used in various products, including health supplements. During the cheesemaking process, most of the lactose is removed with the whey, and the longer a cheese is aged, the more time bacteria have to break down the remaining lactose, resulting in lower overall lactose content. Swiss cheese is aged longer and is therefore considered a low-lactose cheese, along with other aged cheeses such as Parmesan and cheddar.

What You'll Learn
Swiss cheese is low in lactose
Swiss cheese is one of the cheeses that are low in lactose. Other cheeses that are low in lactose include Parmesan, cheddar, pecorino, and Muenster. Aged, hard cheeses have less sugar and lactose, making them easier to digest. The longer a cheese is aged, the more lactose the bacteria can break down, lowering its lactose content. This means that aged, hard cheeses are often very low in lactose.
In addition to cheese, people with lactose intolerance can often tolerate yogurt better than milk. This is because most yogurts contain live bacteria that can help break down lactose, so the body has less to process on its own. Yogurt with probiotics, also known as "live cultures of helpful bacteria", is the best option for lactose-intolerant people.
Lactose-intolerant people can also try taking lactase enzyme supplements to help them eat foods containing lactose.

Whey is a byproduct of cheesemaking
Whey has a variety of uses, both industrial and culinary. Industrially, whey is used as a filler in ice cream and other dairy products, as well as a protein supplement in health foods and dietary supplements. In the kitchen, whey can be used as a substitute for water or milk in savory recipes, or as the liquid ingredient in breads and pastries. It can also be used to preserve foods, such as sauerkraut, and to boil vegetables, giving them a richer flavor.
Whey is also used to make ricotta cheese, a traditional Italian cheese made from the whey that remains after another cheese has been made. American ricotta cheese typically uses whey from cow's milk, while Italian ricotta uses sheep's milk. Whey can also be used to make whey butter, which has a stronger flavor and is cheaper to manufacture than sweet cream butter.
In addition to its culinary and industrial uses, whey has been studied for its potential health benefits. Researchers at Lund University in Sweden found that whey can help regulate and reduce spikes in blood sugar levels in people with type 2 diabetes by increasing insulin secretion. However, it is important to note that whey contains lactose, so it should be avoided by lactose-intolerant individuals.

Whey contains lactose, vitamins, protein, and minerals
Whey is the liquid that separates from milk during the cheese-making process. It contains lactose, vitamins, protein, and minerals, along with traces of fat.
Whey has historically been considered a waste product, but it has since found its way into many products, including health foods and supplements. Whey protein is a popular dietary supplement, particularly for athletes and bodybuilders, due to its high levels of leucine, one of the three branched-chain amino acids, which make it ideal for muscle growth and repair.
The process of pasteurization, which involves heating and then cooling the whey, eliminates 99.7% of bacteria without coagulating the protein. The whey is then filtered through a series of ceramic filters and stainless steel turbines to separate out the lactose and fats, resulting in a liquid that is about 90% whey protein.
Whey contains lactose, a sugar found in milk and its derivatives, which some people are intolerant to. However, the amount of lactose in whey can vary, and it is generally well tolerated in moderate amounts. Aged cheeses, such as Swiss cheese, tend to have lower levels of lactose due to the presence of bacteria that break down the lactose over time. People with lactose intolerance may be able to tolerate harder, aged cheeses in moderation.
Whey also contains vitamins, minerals, and protein, making it a nutritious addition to the diet for those who are not lactose intolerant.

Lactose-intolerant people can eat some cheese
Whey is a byproduct of cheese-making, and it contains lactose. As such, it should be avoided by lactose-intolerant individuals. However, during the process of making cheese, 90% or more of the whey is removed along with the water. This means that some cheeses can be eaten by lactose-intolerant people in moderation.
Lactose intolerance occurs when a person doesn't produce enough of the enzyme (lactase) that breaks down lactose. The severity of lactose intolerance varies from person to person, and some people may be able to tolerate small or moderate amounts of lactose. Lactose intolerance can also worsen with age.
Hard cheeses such as cheddar, colby, Swiss, mozzarella, and Monterey Jack are "virtually lactose-free". Aged cheeses such as Parmigiano Reggiano, pecorino, and gouda also contain very little lactose. These cheeses can be eaten by lactose-intolerant people in moderate amounts.
On the other hand, soft, fresh, and processed cheeses like cottage cheese, ricotta, and burrata contain significantly more lactose than hard cheeses. However, they still have far less lactose than milk, yogurt, and ice cream. People with lactose intolerance should generally avoid creamier cheeses and stick to fresher varieties.
Yogurt is also easier for lactose-intolerant people to digest than milk, especially full-fat and strained yogurts like Greek and Icelandic-style yogurt. This is because most yogurts contain live bacteria that can help break down lactose, and because the straining process removes more of the whey. Probiotic yogurts are the best choice for lactose-intolerant people.

Whey is used in health products
Whey is the liquid that remains after milk has been curdled and strained. It is a byproduct of the manufacturing of cheese or casein and has several commercial uses. Historically, whey was considered a waste product and was pumped into rivers and streams. However, it is now recognised for its nutritional value and is used in health products.
Whey protein is a popular dietary supplement, especially for athletes and fitness enthusiasts. It is commonly used for protein shakes, muscle building, and meal replacement. Whey protein can help build muscle and add mass without weight gain. It can also aid in weight loss by increasing satiety and reducing appetite, leading to lower calorie intake. Additionally, consuming whey protein after a workout can enhance muscle recovery and stimulate muscle protein synthesis.
Whey protein comes in different forms, such as whey powder concentrate and whey protein isolate. Whey isolate is a better choice for individuals with lactose intolerance, as it has lower lactose content. However, those with a dairy allergy should avoid both whey and whey isolate, as they may cause stomach upset. It is important to note that whey protein is intended to supplement a well-rounded and balanced diet and should be used in conjunction with a healthy lifestyle to maximise its benefits.
Whey is also used in other health products beyond protein supplements. It is added to nutritional shakes and bars, infant formula, and baked goods. Whey powder has a neutral flavour and dissolves easily in liquids, making it versatile for use in soups, dips, sauces, and pancakes. Liquid whey is used in ricotta cheese production and can also be used as a stock, adding flavour to dishes.
