Is coffee a health killer?

Drinking coffee has its own advantages and disadvantages. Consuming too much coffee can have many adverse effects on the body, such as not falling asleep easily, hurting the stomach, increasing cholesterol, blocking iron absorption, and increasing the risk of osteoporosis. However, if you drink properly and drink the right amount of coffee every day, you can actually reduce the risk of Alzheimer's disease and Parkinson's disease, and reduce the incidence of gallstones and fatty liver.
No matter how busy you are, would you like a cup of coffee?
Coffee is a drink that many people can't skip for a day, but some people regard it as a healthy poison, so if you want to discuss the quality of coffee, you can probably hold a debate contest that can be debated day and night. I remember that when I was studying in graduate school, I often smelled the fragrance of coffee coming from the professor's office, and a group of teachers and disciples who studied nutrition often discussed various nutrition topics in the coffee. Will this picture be ironic? Do people think that people who study nutrition should not drink coffee? In fact, coffee really has both positive and negative effects on health, and you must drink it in moderation depending on your health.
Drink the right coffee is to enjoy!
Coffee is really a lovely and frightening drink, and its strong aroma is an irresistible temptation. However, according to the statistical results of various studies, it is found that the drip coffee served by general coffee shops is a cup of 230c.c. It contains about 85 milligrams of caffeine (each house increases or decreases according to the concentration of coffee). Basically, it's best not to consume more than 300 milligrams of caffeine a day. Moreover, I suggest that unless necessary, try not to drink decaffeinated coffee, because when removing caffeine, you must use organic solvents, so decaffeinated coffee will have some residual organic solvents that affect your health. Some pregnant women order decaffeinated coffee in order not to drink caffeine, but there is a risk of drinking organic solvents. However, since supercritical extraction is often used in the food industry, doubts about residual organic solvents have been greatly reduced. In addition, some instant coffee is roasted with coffee raw beans, and then mixed with coffee flavor spices and cream, drinking such "coffee" will not get the benefits of coffee.
Coffee that people love and hate.
Let's take a look at the true face of coffee.
Caffeine is the first thing that comes to mind for many people about the substances contained in coffee. In fact, coffee beans contain quite a lot of substances, so the health effects of coffee are not limited to caffeine. Let's explore the advantages and disadvantages of coffee on the body according to different parts of the body:
Effects on the head and brain

[shortcomings]
1. Increase cholesterol: coffee beans contain cafesterol, a compound that increases cholesterol in the body, especially in women. In general, if coffee is directly brewed by machine without filter paper, it is easy to contain coffee oil alcohols; if coffee is boiled and then filtered with filter paper, it will remove most of coffee oil alcohols and reduce the risk of increasing cholesterol. Therefore, it is recommended that coffee should be filtered with filter paper.
two。 Increase the risk of anemia: some people are used to having a cup of coffee immediately after a meal, which can easily hinder the absorption of iron in the meal, resulting in iron deficiency anemia. It is best to drink coffee 1-2 hours after a meal.

two。 People who drink coffee regularly every day can reduce the risk of developing type 2 diabetes.
Impact on women
[shortcomings]
1. Increase the risk of osteoporosis: drinking coffee has a great impact on the bone mineral density of postmenopausal women. Drinking a lot of coffee after menopause will increase the risk of osteoporosis. It is recommended that postmenopausal women drink coffee, limited to 2 cups a day. And it is best to drink coffee with milk (not cream or cream balls).
two。 Increase the risk of preterm birth: the study found that the more coffee consumed, the higher the chance of preterm birth for pregnant women, so pregnant women had better not drink coffee, and if they really want to drink it, taste it with a cup.
