Lactose Intolerance: Understanding Milk Allergies

When a person with lactose intolerance consumes milk or dairy products, they may experience a number of uncomfortable symptoms, such as bloating, gas, diarrhea, and stomach cramps. Although lactose intolerance is not a life-threatening condition, it can significantly affect a person’s quality of life and food choices.

  • Symptoms of lactose intolerance:
  • Abdominal distension
  • Gases
  • Diarrhea
  • Stomach cramps

Lactose intolerance is different from milk allergy. While lactose intolerance is related to the digestion of milk sugar, milk allergy is an immune response to one or more proteins found in milk. Milk allergies can cause a number of symptoms, including hives, wheezing, vomiting, and in severe cases, anaphylaxis.

To confirm the diagnosis of lactose intolerance, a healthcare professional may recommend a lactose tolerance test or a hydrogen breath test. These tests measure the body’s ability to digest lactose or the amount of hydrogen produced when bacteria in the digestive system ferment lactose.

lactose tolerance test Hydrogen breath test
Requires prior fasting Does not require fasting
It consists of consuming a drink containing lactose, followed by blood sugar measurements It consists of consuming a substance that contains lactose and measuring the hydrogen levels in the breath
Used to diagnose lactose intolerance Used to diagnose lactose intolerance

Once lactose intolerance is diagnosed, people can control their condition by adopting a lactose or low lactose diet. This implies avoiding or limiting the consumption of milk, cheese, yogurt and other dairy products. Lactase enzyme supplements can also be taken before consuming foods containing lactose to facilitate digestion. It is important that people with lactose intolerance make sure they continue receiving adequate nutrition from no n-dairy sources, such as vegetable milks, enriched foods and calciu m-rich vegetables.

Choosing the Right Milk: Whole, Skim, or Plant-Based Alternatives

1. whole milk: the whole milk, also known as whole milk, contains a higher percentage of dairy fat than other options. Although it has traditionally preferred for its rich flavor and creamy texture, it contains more calories and saturated fats. Therefore, people with conditions such as high cholesterol or heart disease should consume whole milk in moderation. However, it is worth mentioning that whole milk provides essential nutrients such as calcium, vitamin D and proteins, which makes it a nutritious option for people without strict dietary restrictions.

Comparing the Nutritional Content of Whole, Skim, and Plant-Based Milk

  • Whole milk: it contains more calories and saturated fats, but also provides essential nutrients such as calcium, vitamin D and proteins.
  • Skimed milk: it contains less calories and less fat than whole milk, but also has a lower content in fa t-soluble vitamins.
  • Vegetable alternatives: they vary in nutritional content depending on the type of vegetable milk. For example, almond milk is low in saturated calories and fats, but can lack protein, while soy milk offers a good source of protein, but it may not be adequate for allergic people to soybeans.

Note: The choice of adequate milk depends on individual dietary needs, preferences and any underlying health problem. It is recommended to consult a health professional or a dietitian entitled to determine which is the most appropriate milk for optimal nutrition.

In addition to personal preferences, it is essential to take into account factors such as nutritional needs, allergic reactions and dietary restrictions when choosing between whole, skimd milk or plant alternatives. Understanding the nuances of each option will allow people to make informed decisions that support their general health goals.
