Difference Between Milk Allergy and Lactose Intolerance

Difference Between Milk Allergy and Lactose Intolerance

Have you ever felt that uneasy feeling of bloating, gas, abdominal cramping, and diarrhea after eating or drinking dairy products? You are part of the large group of people that are Lactose intolerant. This condition stems from the fact that you are lacking the enzyme lactase, an enzyme that is usually produced in the small intestine and helps breakdown the sugar lactose, in dairy into glucose and galactose so they can be absorbed into the blood stream. When the enzyme is missing the bacteria in the colon process the lactose instead leading to the symptoms. The condition is harmless but uncomfortable and can lead to awkward social situations. The condition in many is volume dependent since many individuals are deficient in the enzyme but do not completely lack the enzyme hence can only breakdown lactose in small doses.

Is lactose and lactase the same thing?

Lactose is a sugar found in milk made up of one glucose and one galactose sugar molecules. Lactase is an enzyme produced by many organisms that can break down lactose sugar. It is located in the brush border of the small intestine of humans and other mammals. Lactase is essential to the complete digestion of whole milk; it breaks down lactose, a sugar which gives milk its sweetness. Lacking lactase, a person consuming dairy products may experience the symptoms of lactose intolerance. Lactase can be purchased as a food supplement, and is added to milk to produce "lactose-free" milk products; since it breaks down all the actual lactose present in the milk.

As stated above lactose intolerance is dose dependent since most individuals have some of the enzyme in their small intestine and only large volumes of milk or lactose including products would cause the enzyme to be overloaded and allow the symptoms of bloating and diarrhea to occur due to the breakdown by bacteria instead of the intestinal cells.

What is a Milk Allergy?

True milk allergy is not an intolerance and is related to the fact that an individual’s immune system attacks the milk proteins. There are two main proteins found in milk- casein and whey proteins. Casein is found in the solid part of milk and comprises about 80% of milk proteins. Whey proteins found in the liquid component and comprise the other 20%. Milk proteins are not to be confused with lactose which is a form of sugar as explained earlier. People with true milk allergy need to avoid milk proteins which can be found in many products, which are usually labeled as such.

Signs & Symptoms of Milk Allergy

Milk allergy symptoms, which differ from person to person, occur a few minutes to a few hours after you or your child drinks milk or eats milk products.

Immediate signs and symptoms of milk allergy might include:

  • Hives
  • Wheezing
  • Itching or tingling feeling around the lips or mouth
  • Swelling of the lips, tongue or throat
  • Coughing or shortness of breath
  • Vomiting

Signs and symptoms that may take more time to develop include:

  • Loose stools or diarrhea, which may contain blood
  • Abdominal cramps
  • Runny nose
  • Watery eyes
  • Colic, in babies

All true food allergies are caused by an immune system malfunction. If you have milk allergy, your immune system identifies certain milk proteins as harmful, triggering the production of immunoglobulin E (IgE) antibodies to neutralize the protein (allergen). The next time you encounter these proteins, IgE antibodies recognize them and signal your immune system to release histamine and other chemicals, causing a range of allergic signs and symptoms.

As stated, there are two main proteins in cow's milk that can cause an allergic reaction:

  • Casein,found in the solid part (curd) of milk that curdles
  • Whey,found in the liquid part of milk that remains after milk curdles

A true milk allergy differs from milk protein intolerance and lactose intolerance. Unlike milk allergy, intolerance does not involve the immune system. Milk intolerance or lactose intolerance is not at all dangerous and again is dose dependent and depends on the actual volume of mild product that is swallowed. Common signs and symptoms of milk protein intolerance or lactose intolerance include digestive problems, such as bloating, gas or diarrhea, after consuming milk or products containing milk.

Although some studies have suggested that sugar allergies are possible, there has been no evidence of sugar-specific IgE in people who have experienced severe allergy-like attacks

Why Frunutta Uses Minimal Lactose

To get the vitamins your body needs you must be able to absorb it first. Hence the route of absorption of any vitamin into our system is of the outmost importance and hence Frunutta vitamins are meant to be taken under the tongue to absorb directly into the blood stream without additives and preservatives, just pure goodness!

Frunutta tablets use lactose in minute quantities. While it has been reported that the amount of ingested lactose necessary to produce adverse effects varies, it ranges between 12 and 18 gm of lactose (approximately 8 to 12 oz of milk). The amount of lactose in a Frunutta tablet ranges from about 0.4% to 1% of this amount (between 100 to 250 times less), one would not expect such small quantities to result in gastrointestinal symptoms. If an individual use Frunutta products sublingually (under the tongue), majority of its content including lactose, absorb under the tongue and bypass the digestive system.


There is little actual evidence that sugar allergies are even real. In most cases, what you are experiencing is best described as sugar intolerance. Even though the symptoms may be like a food allergy, the underlying mechanisms are quite different.

By contrast, food intolerance occurs when you are unable to break down certain foods (lactose) in your digestive system. This may be due to a few varied factors, including enzyme deficiencies or sensitivities to specific chemicals or additives in the food.

Another significant difference between an allergic reaction and an intolerance is that a person with the intolerance may be able to consume small bits of a problematic food without a negative response.

Frunutta products contain minute amount of lactose used as an organic carrier to avoid using any artificial or non-organic products in our tablets. Also, it should be remembered that individuals are not lactose intolerant under their tongue. Also, the amount of lactose used per tablet as stated prior is so miniscule that if swallowed it has not been known to cause any issues even in lactose intolerant individuals.

This information is only for educational purposes and is not medical advice or intended as a recommendation of any specific products. If you suspect you may be experiencing unusual symptoms when you eat lactose, consult with a healthcare provider. The treatment for lactose intolerance will depend on the level of severity of your reaction, but your healthcare provider can use a variety of testing measures to confirm a diagnosis.
