The taste of coffee is very unique. Although it tastes a bit bitter, the aroma is indeed very strong and the taste is very mellow.

Is coffee bad for your heart?

Some people experience palpitations and headaches after drinking coffee. The saying that "coffee is bad for the heart" has been around for a long time.

However, the Lord wants to tell those people who think they will die if they don’t drink coffee a great piece of good news:

After hundreds of years of debate, the medical community has confirmed that drinking coffee in moderation is actually good for cardiovascular health.

A 2014 paper that brought together 36 studies involving 1.28 million people published a blockbuster: coffee intake and the risk of cardiovascular disease have a U-shaped relationship:

Drinking 1.5 cups of coffee a day reduces the incidence of cardiovascular disease by 11%; drinking 3.5 cups a day reduces it by 15%, which is the greatest benefit; drinking 5 cups or more has no effect.

Each cup here is 150 mL.

Coffee is not a magic drug, but drinking coffee may really be a healthy lifestyle.

Does drinking coffee on an empty stomach hurt your stomach?

First of all, you can rest assured that many studies have confirmed that coffee does not cause gastric ulcers and gastroesophageal feedback.

However, coffee does have some effects on the gastrointestinal tract, such as increasing the secretion of gastric acid, relaxing the esophageal sphincter, and promoting small intestinal motility.

Regarding the attitude towards coffee, the master's advice is:

If you want to drink coffee on an empty stomach, it is not recommended to choose black coffee, but try latte with milk. If you already have gastrointestinal diseases, don't try to kill yourself, just eat something before drinking coffee.

Does drinking coffee cause calcium loss?

In theory, coffee can increase calcium loss, but the reality is:

Caffeine has only a short-term diuretic effect, and the caffeine in each cup of coffee will only increase calcium loss by 2 to 3 mg. If you drink coffee on a daily basis, you don't have to worry too much about calcium loss.

Moreover, if you drink milky coffee, you don’t have to worry. The calcium obtained from milk is more than enough to make up for the milk loss caused by caffeine and oxalic acid.

Will drinking coffee make your teeth yellow?

Hey, this is possible.

Coffee, tea, red wine, these famous coloring drinks, all contain a substance called tannic acid, which is dark brown. If it acts on teeth for a long time, it will penetrate into the inside of the teeth and cause the teeth to turn yellow.

Moreover, ordinary brushing and rinsing are useless for this type of "yellow teeth".

Don't be sad, I have a few methods to help you:

1. Drink with a straw

Reduces the contact between teeth and coffee, suitable for iced coffee;

2. Add milk

Milk contains casein, which can combine with tannic acid, weakening the penetration of tannic acid into the teeth and reducing staining of teeth.

Master, foreigners drink more coffee than us, why are their teeth so white?

The US teeth whitening market is worth $11 billion a year. Get it? :)

Which type of coffee is good?

If you are a regular customer of coffee shops, it is recommended to choose:

Coffee, Americano: Only coffee and water

Latte, Cappuccino: Only coffee and milk

▼

Mocha (with cream and chocolate syrup), vanilla latte and caramel latte (with various flavored syrups) have very high sugar content and are only recommended as desserts occasionally.

If you make it yourself, you can choose high-end capsule coffee, artistic hand-brewed/drip coffee, or instant black coffee (the only ingredient list is coffee beans).

Not a fan of black coffee? Forget about coffee mate and add your own milk.

As for instant three-in-one coffee and canned sweet coffee, they can only be described as "coffee-flavored sweet drinks" and are a poor choice.

No matter what kind of coffee you drink, please be careful: don't make it too hot. Hot drinks (＞65℃) have a risk of cancer.

When is the best time to drink coffee?

The standard answer to this question is: drink in the morning or after lunch.

Coffee at this time can resist the drowsiness after a meal and last for 3 to 4 hours. If you drink it after the afternoon, it may affect your sleep at night.

However, the master has a new answer:

If you have the habit of taking a nap, you might as well try taking a "coffee nap". After drinking coffee, take a 15-20 minute nap, and you will feel more energetic and focused.

First, a 15-20 minute nap will not lead to deep sleep, so there will be no sleep dependence and it will be easier to wake up; second, it takes just 15-20 minutes for caffeine to take effect on the cerebral cortex, which is just enough to refresh you after waking up.

How much coffee is appropriate to drink every day?

Although coffee is good, drinking too much can still cause adverse reactions such as sleep disorders and irregular heartbeat.

The generally accepted healthy upper limit of caffeine intake is 400 mg per day. You can do the math yourself:

A cup of Starbucks latte (large cup, 473 mL) contains about 200 mg of caffeine; a small bag of instant coffee (15 g) contains about 50 mg of caffeine.

// Children and teenagers: It is best not to drink coffee.

Because children's nervous systems are not fully developed and are more sensitive to caffeine, it is best for children not to drink coffee. For adolescents aged 13 to 18, the daily caffeine intake should not exceed 100 mg.

// Pregnant women and nursing mothers: You can drink coffee, but the amount should be halved (caffeine limit 200 mg).

As long as you pay attention to controlling the amount, drinking coffee during pregnancy and breastfeeding is safe for both mother and baby.

Think one cup of coffee isn't enough? Then opt for decaffeinated coffee.
