A kitten for your great work!!

I believe that you are doing an incredible job with this article it needs a little help but you've helped to form already the things that need improvements! However I do want to point out those things that you need to have a little bit more help with. Everything that you've stated within a "*NOTE" is something that I too would have given you some type of edit. I will now review your piece as a whole! There are a lot of ways which you can shorten your sentences which also give a greater sense of objectivity, your one sentence: "Middle of the 20th century..." could be reworded like: "The idea that milk was good for one's health developed in the Mid 20th Century..." This edit follows for a few of the other opening sentences and just a little bit in general. Re-read your sections and see if there is anyway that you can say the same thing more concisely. Syntactically I think that you need to create a more universally unified way of Capitalizing, also a more presentable bullet system. Create a Lead. I approve of the balance and way you structure your info. And overall I find your article topic very interesting! Enjoy the cat!

Welcome

Welcome to Wikipedia and Wikiproject Medicine

Welcome to Wikipedia. We have compiled some guidance for new healthcare editors:

1. Use high-quality sources for medical content (see WP:MEDRS). High-quality sources include review articles (which are not the same as peer-reviewed), position statements from nationally and internationally recognized bodies (like CDC, WHO, FDA), and major medical textbooks. Lower-quality sources are typically removed.
2. Reference tags generally go after punctuation, not before; there is no preceding space.
3. We use very few capital letters and very little bolding. Only the first word of a heading is usually capitalized.
4. Common terms are not usually wikilinked; nor are years, dates, or names of countries and major cities.
5. Do not use URLs from your university library's internal net: the rest of the world cannot see them.
6. Include page numbers when referencing a book or long journal article.
7. Format references consistently within an article and be sure to cite the PMID for journal articles and ISBN for books; see WP:MEDHOW.
8. Never copy and paste from sources; we run detection software on new edits.
9. The ordering of sections typically follows the instructions at WP:MEDMOS.
10. Think carefully before working on featured articles (these have a gold star at top right). It is often hard to improve featured articles.
11. Talk to us! Wikipedia works by collaboration at articles and user talkpages.

Once again, welcome, and thank you for joining us. Please share these guidelines with other new editors.

Lets discuss the following

You basically wrote it in your sandbox and than copied and pasted it into the article.[1]

Much of the content was already discussed in other sections of the article and much of what you did simply duplicated it. Your changes also do not follow either WP:MEDRS or WP:MEDMOS. Important to read both those and the article before you begin. Best Doc James (talk · contribs · email) 21:42, 18 November 2016 (UTC)

Have added back this bit [2]. GHR is a good source just needed formatting properly.

This link to the inside net of Temple University [3] is not useful for those of us without your username and password. Doc James (talk · contribs · email) 21:51, 18 November 2016 (UTC)

Lactose Intolerance Background The ability to digest lactose after infancy changed throughout history to become a far less prominent symptom of aging. This was due to the incorporation of dairy products into the daily lives of certain regions. It is now apparent that particular ethnicities have a higher, or lower, production of lactase as the aging process continues. The culture of an area is able to change the digestive process of it's descendants over time in a form of rapid evolution that has brought about changes visible through a timeline of genetic history. Among the most intolerant to lactose are Native Americans, and the most tolerant are the Northern Europeans. Epidemiology Worldwide prevalence of lactose intolerance in recent populations. About 65% of people experience some form of lactase deficiency as they age past infancy. Sometimes premature babies are lactose intolerant for a period after birth. Typically, in the first four years a person is alive lactase production decreases by 90%, but this varies. Some cultures have developed a tolerance later in life due to a need for unfermented milk products, this is especially true in Northern Europe lineages where it is so rare only 5% of people are unable to digest dairy. Lactose intolerance can start as a child, teen, or even adult and possibly babies, though this is very uncommon . Lactase continues to be produced in the digestive system in Northern Europe, Arabia, and some regions of Africa, but the rest of the world consists of much higher rates of deficiency.. Northern Europeans are least likely to be lactose intolerant However, some regions produce people with great numbers of intolerance, such as Eastern Asia (where about more than 90% are intolerant)  .Native Americans are a group that are entirely lactose intolerant; the Navajo Indians even used their federal supply of powdered milk to paint their adobe homes, because they could not drink it. Statistics: Ethnicities with high rates of lactose intolerance include: Asian american African american Native american Hispanics/latinos Southern Europeans Chart of groups and intolerance Ethnicity Percent That Are Intolerant Swedish 2% Europeans in Australia 4% Swiss 10% American Caucasians 12% Finnish 18% African Fulani 23% African Tutsi 20% American Blacks 75% Australian Aborigines 85% African Bantu 89% Chinese 93% Thai 98% American Indians 100% Lactose Consumption and Intolerance in Contemporary American Culture Due to the railroad expansion in the late 1880s milk consumption grew due to the new system that allowed daily pick ups of fresh milk to be brought to the people. Whole milk made in America became increasingly popular with the two billion pounds produced in 1870 increasing to eight-teen billion pounds by 1900. Got Milk Campaign In the middle of the 20th century advertisers began to spread the idea that milk was very important to one’s health. They promoted a rhetoric that children especially needed to continue to drink milk past infancy. This perpetuated the idea that drinking milk was normal. Still later an increase in intolerance was seen between 2002 and the 1990s . Now, greater than 30 million Americans (typically of African and Asian decent) are unable to digest lactose after childhood is over. Lactose Intolerance Anthropological and Genetic History Hunter-gatherers and Lactose Intolerance Back when food was obtained through a hunter-gatherer culture people did not keep livestock. The children were weened off of their mothers' breast milk earlier, so as to not take unnecessary nutrients from the mother. This resulted in a shorter lactation period which allowed mothers to decrease the time between pregnancies, since their fertility would be able to rise up again once the breast-feeding had ceased. Ultimately, more sequential births resulted in a higher rate of infant mortality for hunter-gatherer families. The cultures that had introduced livestock as a means of living were able to feed their children milk in order to keep more of them alive. This is how the period of lactose tolerance began to extend. For some people, the further back their ancestors introduced dairy the more they can tolerate it later in life. Food culture has a unique relationship with biology where the culture can actually change the ability of the body to digest certain items overtime through exposure, therefore actually changing the digestive chemistry in a certain group. European Origins Back in the 1970s a clay pot was found in Central Poland, the pot was in a location of an old farm and contained an unusual feature; it was covered in tiny holes. This pot dated back 7,000 years to a time when Central Europe was just beginning to farm. Archeologist, Peter Bogucki, who found the pot speculated that it could have been made used for making cheese since it appeared similar to the modern day tool used to separate the milk fat solids from the liquid whey to prepare the cheese. This was confirmed when in 2011 Mélanie Roffet-Salque analyzed the fat debris located on the pot. She found enough evidence of milk fat to conclude that this pot was a tool for cheese making. This pot became the first evidence of cheesemaking in Europe. Around the time this pot was made there was a spread of a genetic mutation throughout Europe that allowed people to digest lactose. It is now believed that many of the current Europeans are descendants from the first dairy farmers in the area. Today, dairy is a prominent part of Polish food culture, especially fermented milk products like sour cream, cheese, and yogurt. Dairy in Poland does not just come from cows now, but is also often from sheep or goats as well. A popular form of dairy in Poland is sour cream. It is used in a variety of dishes including salad dressings, cakes, soups, and roast meat dishes just to name a few. Polish yogurt, known as kefir, is likewise a popular form of dairy consumed in the country. Cheeses in the country are made with sour milk and cheese curds, and varies by region. The Polish enjoy using their cheeses to make cheese fillings, cheesecake, and cheese soup all of which are typically made with the cheese that comes from he curds or sour milk. Middle Eastern Origins Middle Eastern farmers from 11,000 years ago started to learn to heard cattle as the transition from hunter-gathering to farming began. They learned that by fermenting milk into cheese or yogurt they could reduced the amount of lactose to a bearable level. This along with the European mutation are referred to as the Milk Revolution. Genetics Genetically, the LCT gene encodes the steps to making the lactase enzyme. It is natural for this gene to reduce activity with age, and is controlled by regulatory element. Weaning babies off breastmilk could have originated due to the body’s natural decrease in production of lactase. Without lactase dairy will remain in the gut stealing water from the body until it swells and forms a gas producing microbes substrate. Women are more likely to be lactose intolerant than men . Mutations Certain traits spread due to migration. Some groups over time developed a mutation on chromosome 2 that allows them to continually produce lactase. This means people can keep drinking milk which is important for certain milk reliant communities. Those who do not have the mutation become intolerant. It is unknown when this mutation began. Some estimate that in 4000 B.C. mutations in Sweden and the Arabian Peninsula started the mutation and spread to Europe. Others say one case in the middle east triggered this in 4500 B.C. and it then spread from there. A few believe that there was a more contemporary shift mutation originating in the East African Tutsi.
