Causes bloating and digestive issues

Drinking too much milk shows signs that are not just seen in those who have a full-blown intolerance to it, but even in other people. Drinking too much milk can cause digestive issues such as bloating, cramps, and diarrhea. If your body is not able to break down lactose properly, it can cause a “leaky gut,” which is when bacteria and toxins can leak through the intestinal wall. This can lead to gassiness and other digestive issues can happen because of it.

When you consume milk you may have noticed that it makes you feel fuller. That is why when you have it too much it can disturb digestion, and release some enzymes in the bloodstream which can lead to gastrointestinal issues. As per research (R) the inhibitors which are found in bovine milk, cause imbalances in digestive enzymes and overproduction of an enzyme that destroys the relationship between the intestinal cells which is known as trypsin.

Many people are not able to digest milk and dairy products well that is because they have lactose intolerance it happens when your body is not able to produce enough enzymes that help to break down the milk sugar(lactose) when you consume it. You know that 65% of people who are adults have some form of lactose intolerance, said the American National Institutes of Health.

Nausea is one of the biggest side effects and in some extreme cases, vomiting can happen after consuming any form of dairy that contains lactose, including milk, ice cream, or cheese. So be careful when you are consuming any dairy products and if you still want to consume dairy products, but believe you have lactose intolerance, there are plenty of dairy-based alternatives, like lactose-free milk, ultra-filtered milk, and lactose-free yogurt as well as plant-based options like milk substitutes.

3. Feeling of tiredness

Feeling of tiredness

When you consume too much milk in a day it can contribute to a “leaky gut.” A1 casein, found in dairy milk can sometimes lead to inflammation which may increase the permeability of the gut lining and disturb microbe balance. This results in microbiome dysbiosis, which leads to more bad bacteria than good since the gut bacterial microbiome is imbalanced in the body. Studies have recently connected that a leaky gut has been associated with symptoms such as chronic fatigue and lethargy, in which you feel tired and leads to debilitating fatigue that may not be alleviated by rest.

This is why a lot of people who suffer from milk allergies are suggested to try out A2 milk variants. This A2 milk variant removes the a1 protein, and it may be a good substitute for those with milk intolerance.

4. Breakouts on the skin

A 2014 BMJ (R) study found reports that older men who drank very little milk were less likely to suffer from broken bones or inflammation than women who drank milk in less quantity.

There was research in The Journal of Nutrition (R) which was published in 2015 found that eating dairy foods increased low-grade inflammation in some people of German adults. Women who drank milk three or more glasses daily have shown an increased risk of bone fracture of about 16 percent, and the risk of a broken hip was increased 60 percent, which was reported. When you notice a difference in your bone density because of milk that is because of the calcium intake you can opt for other nutritionist products which are dairy-free that have calcium in them. This will ensure your body’s safety and does not cause any harm to it. Women especially tend to be affected because of this.

It was found by the researchers that women who drank three glasses of milk or more every day had a nearly doubled risk of death and cardiovascular disease, and a 44 % increased risk of cancer compared to women who drank less than one glass per day. While the overall risk of death increased about 10 percent in men when they drank three or more glasses of milk daily.

Hence it is advised not to go overboard with milk, because it might cause more harm than good!

May cause weight gain due to excess calories in dairy

Dairy products are indeed said to be nutritious, with important vitamins and minerals such as calcium, potassium, and vitamin B12. but they also contain a lot of fat, which makes them high-calorie-dense foods.

This is not a bad thing as a study has shown that consuming full-fat dairy can actually help prevent obesity. Although it is not entirely clear why, they say that the fat content may contain some metabolic benefits (R), and potentially make you feel fuller and more satisfied after eating. But if you are trying to lose weight, keep in mind that any weight or fat loss depends on a calorie deficit, so those extra calories in milk or dairy products can cause you to gain weight instead and that may impede your efforts.

10.May result in chronic inflammation

May result in chronic inflammation

As you may have noticed consuming too much milk makes you feel fuller and cause bloating but it also gives you digestive issues because it is highly acidic, although it does contain high amounts of calcium that acts as an alkaline agent by nature. Milk is naturally rich in acids that may cause calcium deposits to build up and potentially cause arthritis and also long-term inflammation.

As we once believed it may not necessarily keep our bones strong. Most plant-based foods do a much better job, you can opt for other foods that do not contribute to chronic inflammation like chard, kale, almonds, and figs.

Your skin is what makes you feel confident and beautiful at the same time, and that is why it can be debatable but skin health is as much as important as your overall health. How is it important you may wonder? But you only have better skin when your internals are doing better. Your skin is the largest part of your body and whatever the internal body can’t get rid of, the skin will try to do so itself. When it comes to the liver and digestive system having a hard time with internal wastes that can’t be properly removed you will especially find it true.

When you consume too much milk or even in a small amount for some people or dairy products, the skin usually takes a major hit. When you notice acne, redness, splotchy, or dull and unhealthy skin you will understand. Many people may have noticed tremendous improvements in their skin the first few days without dairy.

According to a report from the United States Department of Health and Human Services, it is safe to drink three cups of milk daily for a person who is over the age of nine can drink three cups of milk per day. This is based on the theory that milk and other dairy products are excellent sources of calcium, phosphorus, vitamin A, vitamin B12, protein, potassium, zinc, choline, magnesium, and selenium. It is not necessary to consume whole three cups of milk daily because you don’t need all of that milk in order to reap the beverage’s nutritional benefits.

Although as you know there are some people who must stay away from milk completely since these people are the ones who are lactose-intolerant. This Lactose intolerance is caused because of the deficiency of an enzyme in the body called lactase, which breaks down lactose found in milk and is essential for its complete digestion.
