How to drink coffee healthily?

That appropriate bitterness, with rich, mellow, fascinating smell, this is the charm of coffee. Especially when the weather turns cold, when I have a cup of hot strong coffee, I will naturally have a warm feeling in my heart. Whether you're tired of walking, finding a place to sit down, finding a good place to chat with friends, or looking for a pick-me-up in the office, you can't help but want to get close to coffee. But how to drink coffee to be healthy?

Be in close contact with coffee

Caffeine can stimulate the central nervous system and muscles, so it can cheer up, enhance thinking ability, and restore muscle fatigue. Acting on the cardiovascular system, it can improve heart function, dilate blood vessels and promote blood circulation. For the gastrointestinal system, it can help digestion and help decompose fat.

Help to lose weight

I believe many people have heard that drinking black coffee can help you lose weight. in fact, this is only one of the factors. Caffeine can indeed accelerate the decomposition of fat, but at the same time, it depends on muscle exercise to convert the excess fatty acids into heat energy. Without matching exercise, the excess fatty acids flow back down the bloodstream and re-accumulate fat. So after drinking coffee, you need to be active at the same time in order to play a real weight loss effect! Coffee itself has calories, but not much. The main calories are the cream and sugar you add when you drink coffee.

Antioxidant capacity

In recent years, as long as foods with antioxidant functions are popular in the market, well-known vegetables and fruits that are rich in A, C, B vitamins, as well as tea, which is quite popular in Japan, are regarded as healthy foods because they are rich in antioxidants, which can resist the harm of free radicals to the human body. A few days ago, a research report pointed out that coffee contains four times more antioxidants than tea, which is more resistant to cardiovascular disease, and coffee itself is in line with the principle of antioxidants, and the color (dark) is bitter. Each coffee contains different antioxidants depending on the way it is brewed. For example, American coffee contains the least antioxidants, while Espresso contains the most antioxidants. After the addition of cream, coffee will not affect its antioxidant effect.

Improve dryness of the eyes

Foreign reports point out that coffee drinkers are significantly less likely to suffer from dry eyes than those who do not drink coffee. This is mainly related to the purine ingredients in coffee (purine-containing eye drops that stimulate glands to secrete fluid and have some protective effect on the eyes). This is of course good news for computer users who love coffee, but it should be noted that coffee itself has a diuretic effect, even if some of its ingredients have a protective effect, but for people who already suffer from xerophthalmia, and those who take any drugs containing diuretics, caffeinated beverages must be prohibited so as not to aggravate the loss of water in the body.

It can relieve the pain

Headache caused by a good night's sleep, or pain caused by vasoconstriction on the temple side, the pain caused by these non-organic factors can be relieved with coffee, but it must be drunk in the morning or noon (note: prohibited from afternoon to night).

The amount of coffee

Coffee is good for the body, but you can't drink more than 2 cups a day. For people who are prone to tension and anxiety, drinking too much may be harmful.

Coffee time

Drinking coffee is best after breakfast and lunch, because it can promote gastrointestinal peristalsis, help digestion, can break down high-calorie, high-fat foods, and will not cause irritation to the stomach like drinking coffee on an empty stomach. It's best not to drink coffee after dinner, for fear it will affect your sleep. If you want to stay up all night by drinking coffee, you may drink too much without knowing it, which is bad for your health.

Make a mess when you are nervous

Caffeine helps to improve alertness, agility, memory and concentration. But drinking more coffee than you are used to will produce the same dose of stimulants that you are used to, which can cause nervousness. For people with anxiety disorders, caffeine can worsen symptoms such as sweaty palms, palpitations and tinnitus.

Aggravate hypertension

Caffeine is often combined with other simple painkillers because of its analgesic effect, but if you take it in large quantities for a long time, if you already have high blood pressure, using a lot of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, coupled with emotional stress, it can have a dangerous multiplication effect, so people at risk of high blood pressure should especially avoid drinking caffeinated drinks during stressful times at work. Some people who drink coffee all the year round think they are immune to the effects of caffeine, but this is not the case. One study shows that blood pressure can rise for up to 12 hours after drinking a cup of coffee.

Induce osteoporosis

Caffeine itself has a good diuretic effect, if you drink a lot of coffee for a long time, it is easy to cause bone loss, which will adversely affect the preservation of bone mass and may increase the threat of osteoporosis for women. But the premise is that people who don't get enough calcium in normal food, or people who don't move very often, plus women after menopause, calcium loss caused by lack of estrogen, coupled with a large amount of caffeine, may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still stop eating for fear of choking.
