The harm of mixing black coffee with milk

As people pursue a healthy life, more and more people are choosing to drink coffee. Adding milk to coffee has become a common way of drinking. However, you may not know that there are some potential hazards when mixing milk and black coffee. This article will introduce these hazards in detail and hope to draw everyone's attention to dietary health.

Affects nutrient absorption

First of all, mixing black coffee with milk will affect the body's absorption of certain nutrients. For example, studies have shown that when calcium and caffeine are taken at the same time, the two will compete with each other for absorption channels, thereby reducing the speed at which calcium ions enter the blood circulation system. This means that even if you take enough calcium foods or supplements, you may not be able to effectively absorb enough calcium after drinking a drink containing a large amount of caffeine and milk.

In addition, caffeine can affect the body's absorption of iron. Iron is one of the essential trace elements for the human body. It plays an important role in hemoglobin synthesis and oxygen transport. However, when you drink milk while drinking coffee, caffeine will interfere with the body's absorption of non-hemoglobin iron. This may lead to iron deficiency and cause health problems such as anemia.

Increase cholesterol intake

Another danger of drinking black coffee with milk is that it increases cholesterol intake. Milk contains a certain amount of fat, including saturated fatty acids and cholesterol. Although moderate intake of these substances is not a big problem for the human body, if you drink a lot of black coffee with milk every day, it may cause too much cholesterol to enter the body.

High cholesterol levels are closely related to health problems such as cardiovascular disease and arteriosclerosis. Long-term high cholesterol intake will not only affect the health of the blood circulation system, but may also lead to serious diseases such as high blood pressure and heart disease.

Effects of caffeine

In addition, mixing black coffee with milk will also affect the effect of caffeine. Black coffee contains a certain amount of caffeine, which is a stimulant that can refresh the mind. However, after adding milk, the protein in it will combine with caffeine to form a complex and reduce its stimulating effect on the central nervous system.

This means that if you’re drinking black coffee to improve alertness and concentration, adding milk to it might not be a wise choice. Instead, you might need to increase your intake to achieve the same effect.

Other potential hazards

In addition to the above hazards, there are other potential problems with black coffee with milk. For example, in some people (such as those with celiac disease), consuming dairy products may cause allergic reactions or indigestion. If you belong to these groups, adding milk to coffee may cause discomfort.

Additionally, some studies have found that the lactose in milk may interact with caffeine and cause gastrointestinal issues. If you are prone to digestive issues like excess stomach acid, heartburn, or diarrhea, drinking black coffee with milk may worsen these discomforts.

in conclusion

In summary, although adding milk to coffee can change the taste and reduce bitterness, we must also be aware of some potential hazards. Influencing nutrient absorption, increasing cholesterol intake, and affecting the effect of caffeine are all factors that need to be considered. If you care about your health and want to maximize the benefits of coffee, please choose carefully whether to add milk to black coffee.
