Knowledge of the World of Lactose Intolerance


Normal Lactose Digestion Compared to Lactose Intolerance

           Lactose intolerance is when the body does not make enough lactase to break down lactose, a sugar found in milk and many other milk derived diary products.  The enzyme that breaks down lactose is lactase, an enzyme found on the wall of the intestines.  Lactase breaks down lactose into galactose and glucose.  The activity of lactase becomes reduced after breastfeeding, and at that point the body no longer needs as much lactase. This is not the same thing as a food allergy to milk.  When lactose moves through the colon (large intestine) without being properly digested, it can be really uncomfortable to a person.  You can get gas, bloating, and even really bad stomach pains.  Some people who have Lactose Intolerance cannot digest any milk products whatsoever.  Other people though can eat or drink small amounts of milk products, or even certain types of milk products without any problems.  Lactose is a disaccharide, C12 H22 O11, and is in animal cells.  It is also a white crystalline substance.

         Lactose intolerance is common in adults.  It occurs more often in Native American, Asian, African, and South American people that are among the European descent.  The challenge of being lactose intolerant is how to eat to avoid discomfort and to get enough calcium for strong bones.  Lactose intolerance usually runs in families, and the symptoms usually develop during the teen or adult years.  Sometimes the small intestine stops making lactase after a short-term illness such as the stomach flu or as part of a lifelong disease, or the small intestine sometimes stops making lactase after surgery to remove a part of the small intestine.  In these cases, the problem can be either permanent or temporary.  
The Hydrogen Breath Test
Symptoms of Lactose Intolerance

         In rare cases, newborns are lactose-intolerant.  A person born with lactose intolerance cannot eat or drink anything with lactose.  Some premature babies have temporary lactose intolerance because they are not yet able to make lactase.  After a baby begins to make lactase, the condition usually goes away.  Symptoms of lactose intolerance can be mild to severe.  Symptoms usually begin 30 minutes to 2 hours after you eat or drink milk products.  Symptoms may include bloating, pain or cramps, gurgling or rumbling sounds in your stomach, gas, loose stool or diarrhea, or throwing up.  You can do a test called the hydrogen breath test where if you are lactose intolerant, you will produce more hydrogen gas.  You can also take over the counter products like lactaid, which helps to digest the lactose.  If you drink milk with food, that will also help.  There are also diary products like yogurt and hard cheeses that a lactose intolerant person can eat without hurting them afterwards because they have smaller amounts of lactose in them.  There are also alternatives to milk and diary products like soy, "dairy free products," or "lactose free" products too.   
Milk is bad for you altogether
           current research: April 3, 2013 by Arjun Walia.......Approximately 75% of Earth's population is lactose intolerant, and that is actually perfectly natural if you are.  The statistics vary from race to race and country to country.  We are the only species on the planet that drinks milk from another species.  Since lactose's only function is the digestion of lactose in milk, most mammal species experience a dramatic reduction in the activity of the enzyme after weaning.  People that continue to drink milk have evolved as an adaptation to the consumption of non-human milk and dairy products consumed beyond infancy.  Our diet has changed a lot, which makes our genes adapt, but it's not an easy process.  This is why most humans are lactose intolerant.  Every other species wean and then never drink milk again, and because of that we don't have an enzyme to break down the sugar in milk.  But during human evolution, some humans experienced a mutation in the LTC gene, which is the lactase gene, and these mutations allow us to process lactose as adults.  With over 75 percent of humans on the planet unable to properly process it, it is enough evidence that we are not doing what is natural for and to our bodies.  We are suppose to be lactose intolerant!  Undigested lactose in the small intestine acts like an osmotic agent, causing water and electrolytes to be pilled into the intestines, which results in diarrhea, bloating and gassiness.  The body struggles and compensates, as well as protects itself by developing coping methods for our unnatural habits.  Now, there are movements occurring to try and remove milk from school cafeterias because too much information is being released that milk is very bad for you.  Now in stores,  they are advertising more alternative milk products like rice milk, almond milk, and coconut milk.  Sadly, there is NO CURE yet for lactose intolerance people.
           
According to the National Dairy Council there are three different types of lactates deficiencies.
1-Congenital Lactase Deficiency-This is an extremely rare condition where intestinal lactase is absent at birth
2-Secondary Lactase Deficiency-This is a condition that is the result of some disease or things such as radiation treatment.  This condition is usually only temporary and a person can resume normal lactase production after they get better.
3-Primary lactase deficinecy-This is the most common type.  Primary lactase deficiency is when individuals slowly lose the ability to produce lactase as they get older.  Usually a person's ability to produce lactase is determined genetically.

            I myself am lactose intolerant.  I found out in the middle of 8th grade from my doctor.  I think it was because I was consuming too much diary products because at my middle school we were only allowed to bring diary products, or it could just be that since I am a human, milk products are just not made for me.  Now, I take the lactaid supplements before I eat diary products, which seem to help.  I learned a lot about lactose intolerance from this research though.  One thing that I was really fascinated with was with the hydrogen breath test.  I would really like to do that one day just to see if I really have lactose intolerance because my doctor just said I had it when I told her my stomach hurt after I ate lunch, but my doctor never really tested me for it.  Now, by doing this research, it makes me really want to stop consuming diary products all together because in one of the videos I watched, it says that milk is really only for young mammals, which we also learned in class.  I also learned that I have the type three lactate deficiency, which is the most common type.   It is not worth it for me and for others to consume diary products who are lactose intolerance because of the extreme pains it gives you after consuming it.  I have learned just how bad diary products is to and for your body if you are lactose intolerant, that if you consume too much of it, you could possibly even die.  The most important thing I have learned from this research is that when your body reacts to something you are doing to it in a negative way, you should stop what you are doing to it immediately because it is not worth it to be in pain all the time, and you also don't want to do something to your body that can question your life.

  1. I'm really impressed with this post. There's a lot more to lactose intolerance that I didn't know. But I wanted to ask, why do you think there are such ranges in symptoms of lactose intolerance? Is it because of levels of lactase production or the amount of lactose ingested? And since lactose is usually in sources that supplement calcium how would this affect a person? By this I mean what are maybe some other sources that could provide the needed calcium to keep the bones strong? I'd be interested in hearing your reply or resolutions to my questions.

    1. Well, I think there are so many ranges in symptoms of lactose intolerance because I truly believe that we are not even suppose to consume dairy products, period because of what I researched. And, we all know from class even that lactose is for young mammals (babies), not for children, teens, or adults. All these symptoms occur I think because the body is trying to tell you/us to get this stuff out of me, and it basically doesn't know what to do with it. I personally have had the affects of consuming dairy even though I am lactose intolerant, and I have had all those symptoms. It literally feels like your body is going crazy BECAUSE it can not handle itself when something strange and dangerous is in the temple of the body wrecking it. It is definitely because of the levels of lactase production and the amount of lactose ingested. If you are lactose intolerant, which most of us are, the more dairy you consume, the more painful the after affects will be. As we just learned in class, vitamin D can keep our bones very strong from the sun, and also vitamin K can, which is basically the green vegetables. All leafy greens (kale, greens, broccoli), beans, oranges, soybeans, and nuts can keep your bones strong as well. I hope I answered your question. If you need something to be clarified or if you want to ask another question please ask! :)

  2. this post has a lot of intriguing information. The part about the how lactose and tolrance varies from country to country and race to race. is there any statistics of lactose-and-tolerance in the australian population? could this also be hereditary to the australian population ? it would be interesting to hear your response

    2. I am sorry I did not include Australians, but they in fact do have a high risk of getting lactose intolerance. This could be because of their genes because as we both know genes are the ones who play a key role in letting us know if we can produce enough lactase enzyme or not. Many ethnic cultures are in fact more likely to be lactose intolerant because their diets call for low lactose intake. Over generations, these ethnic groups didn't pass on the enzyme to break down dairy because they aren't consuming dairy themselves. I truly believe though that we aren't even suppose to consume dairy products whatsoever because of what I researched about lactose intolerance being only for newborns, which has a very good argument. It is also sort of obvious on that being the case because SO many people in the world today are lactose intolerance, and it is a growing issue. I hope that answered your question because I know my answer was a little scattered because their wasn't a lot on Australians in the topic of lactose intolerance. If you have any more questions please feel free to ask, or if you need can clarification I am here. :)....Hailey H.

  3. Hailey, this a great post! I am intrigued by the fact that Congenital Lactase Deficiency can actually happen in babies. How could a baby get the necessary breast milk during the first couple weeks? I wonder if a person has the gene for lastase enzyme, so so they gradually mutate out the gene or does the body simply stop accepting it? I heard you talking about how you were lactose intolerant at lunch and glad you decided to do your blog on it, as it becomes very personal. It's also interesting how a majority of the population doesn't even have the LTC gene necessary to process it as adults, even though it is a custom throughout the world as cow's milk as a natural source for calcium to help the body grow, yet it really isn't natural for the body at all! Even though there is no cure, it seems like we don't really need a cure for it since its not even natural to the body, and those lactaid pills seem to help these people fit into the society based around cow's milk today.

  4. I am glad you enjoyed the post Robert! If a baby is lactose intolerant, it will show signs of severe diarrhea. The baby would need a special, lactose-free infant formula, which I am sure you can get at a store. Also sometimes it is just a phase for the baby, which it can soon grow out of in a few weeks. And to answer your other question, as most people get older, the body might not produce as much lactase, so some people become lactose intolerant and the body simply stops accepting milk products. Some people can handle milk products, but I think everybody out there has one dairy product that upsets their stomach, which means you can still be lactose intolerant, but it is not as severe. Some people with lactose intolerance can handle some milk products, and not the others. There are so many people out there that are lactose intolerant and as the years go on, I predict that like 90% of the world will be lactose intolerant. We as humans are not suppose to have milk products! I hope I answered your questions! If you have more or need some clarification please ask! :)

  5. this is fascinating. your post caught my eye because i've always been interested in lactose intolerance my dad used to be lactose intolerant, but it seems he grew out of it. you mentioned that sometimes we stop making lactase after a short-term illness, but how long does that last? like, how long do we stop making lactase for? also, "we are the only species that drinks another species' milk" caught my eye. i had never thought about that, but its true! i wonder why that is. i wonder if in animals, does the need for lactose just disappear after theyre fully grown? because fully grown mammals dont drink milk. that'd be an interesting topic to research. thanks for a great post, hailey!

    1. I am so glad you liked my blog Nabilah! With the short term illness, the lactose intolerance usually lasts until you get better. To answer your other question, yes, the need for lactose just disappears after they are full grown, its just the way us mammals are suppose to be. If you have anymore questions do ask!

  6. I thought you were very clear and had a lot of detail when explaining what lactose intolerance is. I read in your blog that lactose intolerance runs in the family, and I know you are so I am curious to know if you know someone else who has it in our family. I am also curious if you know why lactose intolerance develops in the teen and adult years rather than the childhood years?

    1. Well, as my blog says, us mammals should not even have dairy products whatsoever, I don't really know anyone in our family that has it but even if you ask mom certain dairy products hurt her...It just hasn't affected all of us yet. But, since you are in my family you can go back in the family tree and look that up if you would like if that really interest you. And if you read my blog and listened in class, you would see that adults and teens bodies start to lose the enzyme for it because it is only made for young mammals to get them going/eating in life because all they can eat without teeth is breast milk....Our bodies change hannah....I hope that answers your questions:D
