Can I add milk to my coffee? The advantages and disadvantages of coffee

With the influx of Western culture, more and more people are drinking coffee. In addition to sugar, you can also add milk to coffee. So, can you add milk to coffee? Let's take a look at it together!

Only by rationally and scientifically allocating our daily diet can we promote the health of our body. On the contrary, if the diet is improper, it will cause serious damage to our body. Therefore, nutritionists warn consumers that coffee + milk is harmful to health.

Drinking coffee in moderation (no more than two cups a day) is good for the heart and brain. Calcium-rich milk is a great drink for strong bones. However, mixing milk and coffee together for a long time will damage the liver because this mixture will produce an unstable and difficult-to-digest emulsion. The French are the most coffee drinkers in the world with milk, but the number of people suffering from hepatitis among them is not more than that of other countries. It turns out that there is a little trick: pour coffee into milk instead of milk into coffee, and it is best to use skim milk. This will prevent the milk from going bad in your stomach.

There is no harm in drinking coffee with milk, but you need to pay attention to the brewing method.

1. If you are using milk powder, do not mix milk powder and coffee powder together, otherwise small white solids will float on the surface. Of course, except for the taste, it is harmless to the body. The correct way to brew is to brew the milk powder (it can be dissolved a little) and then brew the coffee, and then pour the milk into the coffee.

2. If you are using creamer (powdered), you can brew it together with the coffee powder. If it is liquid creamer, add it after brewing the coffee.

So, you can add milk to coffee. After the explanation of nutrition experts, it is not difficult for us to find that milk and coffee are also a golden pair in some aspects. Not only can milk be added to coffee, but milk powder and creamer can also be put in milk. However, we must pay attention to the brewing method to avoid affecting the taste of our coffee.

The tannic acid in tea and coffee will reduce calcium absorption. Therefore, it is best to drink tea and coffee between meals.

If a pregnant woman drinks a lot of caffeinated beverages and foods, she will experience symptoms such as nausea, vomiting, headache, and increased heart rate. Caffeine can also enter the fetus through the placenta and affect fetal development.

Pros and Cons Analysis

Benefits of coffee

Coffee beans contain about 100 different substances, including caffeine, tannic acid, oil and nitrogen compounds. Every 100 grams of instant coffee contains 44 to 100 mg of caffeine, and every 100 grams of brewed coffee contains 64 to 124 mg of caffeine. Coffee is a stimulant that has many effects on the human body. It can act as a diuretic, stimulate the central nervous system and respiratory system, dilate blood vessels, accelerate heartbeat, enhance skeletal muscle strength, and relieve brain and muscle fatigue.

Disadvantages of coffee

1. People who are used to drinking a lot of coffee will experience symptoms such as headache, irritability, muscle tension and nervousness when they stop drinking coffee, and the symptoms will disappear after taking caffeine.

2. Women who are pregnant or breastfeeding should drink coffee in moderation because caffeine can penetrate the placenta and appear in breast milk.

3. Drinking coffee can cause mental excitement. Within 4 hours after drinking coffee, caffeine will affect sleep.

Coffee and Health

Whether coffee affects health is a topic of great concern to many people, and scientists have been arguing for many years. But so far, scientific research has not found conclusive evidence that drinking coffee in moderation is harmful to human health. Between 1970 and 1980, the results of studies in this area were generally negative. Extensive media reports made people feel uneasy about the caffeine in their diet.

In the 1990s, due to more rigorous and accurate testing procedures and more knowledge about other aspects, such as alcohol consumption, exercise habits and smoking, these studies have been able to clarify some unresolved controversies in previous studies. In particular, they have been able to provide a lot of new knowledge about caffeine and health.

Coffee addiction problem

A university in England invited 300 volunteers to participate in the study. They divided coffee lovers and non-coffee lovers into two groups and stopped drinking coffee 16 hours before the test to observe the changes in their concentration. After "quitting coffee" for 16 hours, only coffee lovers were allowed to drink coffee, while non-coffee lovers were not allowed to drink it. The results showed that the concentration of those who drank coffee was the same as that of non-coffee lovers, which was only at a normal level. Therefore, it can be inferred that even if non-coffee lovers drink coffee, it will not help improve concentration or work efficiency.

The scholars in charge of the investigation said that the human body has adenosine, which slows down the reaction. The reason why people feel "refreshed" after drinking coffee is that caffeine stops adenosine from entering cells, making it difficult for people to feel sleepy. The study also pointed out that caffeine can narrow blood vessels, speed up blood circulation, and cause headaches. Some coffee lovers will experience headaches, irritability, muscle tension, and nervousness if they do not drink coffee.

Does drinking coffee affect sleep?

Many people have had the experience of being unable to sleep after drinking coffee due to mental excitement. This is because there is a conductive substance called adenosine in the human body, which can control nerve activity, slow breathing, weaken emotions, reduce gastric acid secretion and have a diuretic effect. Caffeine can impersonate adenosine, making the body think that the effect of adenosine has already occurred, making you feel energetic, increase gastric acid, urinate more frequently, and naturally make it more difficult to fall asleep. It is worth noting that this short-term wakefulness caused by caffeine does not mean that physical strength has really been restored. In addition, everyone has a different metabolic rate for caffeine, and their sensitivity to it is also different, so some people do not feel that their sleep is affected after drinking coffee. Therefore, a cup of hot coffee after getting up in the morning can invigorate the body and mind and make you feel more comfortable, but it may cause insomnia at night.

Will it cause calcium loss?

As people pay more and more attention to the problem of calcium loss and osteoporosis, they also have considerable doubts about coffee. As for the relationship between caffeine intake and osteoporosis, it is still under study. There is no direct evidence that caffeine causes osteoporosis, but some studies have pointed out that caffeine increases calcium loss. Therefore, it is recommended that coffee lovers should eat more high-calcium foods to supplement calcium, such as preparing custard slices or custard cakes to enjoy with coffee, which can not only supplement calcium, but also make coffee more delicious.

Coffee and Beauty

There is no research result that shows that the caffeine and melanin in coffee have an absolute relationship with the increase of melanin in the skin or skin aging. On the contrary, a moderate amount of caffeine can accelerate metabolism, promote digestion, improve constipation, and improve the roughness of the skin. Regarding the fact that caffeine can accelerate metabolism, there is a saying that coffee can accelerate the burning of calories and achieve the effect of weight loss. Basically, the theory is correct, but this kind of calorie burning will not lead to much weight loss. If sugar and creamer are added to coffee, the calorie calculation is even more inconsistent with the principle of weight loss.

Coffee is a good friend of fitness

Another benefit of coffee is that it can increase your physical strength, which helps you exercise longer and more effectively. Caffeine is essential in group sports because it enhances concentration and reaction time. Drinking too much coffee, combined with intense exercise, can cause tachycardia and excitement, leading to insomnia, neurosis and other symptoms.

Drinking coffee frequently may lead to sub-health

The survey found that sub-health among white-collar workers is extremely common, with about 98.8% suffering from different degrees of sub-health. Among them, people aged 26 to 30 have become the main force of severe sub-health, accounting for as high as 64.2%. First-tier cities in particular have the highest rate of severe sub-health. The economic and emotional pressures have forced white-collar workers to exchange success for the cost of overdrawing their health, leading to the emergence of many social problems.
