Coffee is one of the beverages that brings many benefits to human health. However, coffee is not for everyone, especially the following 4 subjects.
After drinking coffee, you can refresh your mind and improve your energy, because some of the ingredients in coffee stimulate the nerves of the brain. Coffee also brings many health benefits, but drinking too much coffee chronically without controlling the correct dose can also be harmful to health.
The benefits of drinking coffee
1. Prevent diabetes
Antioxidants such as chlorogenic acid in coffee can improve the sensitivity of human cells to insulin, which is more conducive to blood sugar regulation. Several observational studies have shown that coffee drinkers have a 23-50% lower risk of developing type 2 diabetes than non-coffee drinkers. So drinking two cups of coffee a day can significantly reduce the risk of type 2 diabetes.
2. Get rid of headaches
A cup or two of coffee a day can reduce migraine symptoms. Headaches are usually caused by dilated blood vessels around the brain, increasing blood flow to the brain. However, the caffeine in coffee can effectively relieve headaches by constricting blood vessels and reducing blood flow to the brain.
3. Protect your heart health
A related study found that people who drank a moderate amount of coffee daily were associated with a significantly lower risk of stroke in older adults, compared with those who never drank coffee. This is because the relatively high antioxidant content in coffee can protect blood vessels from damage, which can promote heart health and reduce the risk of stroke.
4. Protects the liver
Drinking coffee in moderation can help reduce the risk of liver diseases such as cirrhosis and fatty liver. Drinking two cups of coffee a day can reduce the risk of liver cancer by 43% because the chlorogenic acid and caffeic acid in coffee can slow or stop the growth of liver cancer cells in the body.
5. Improves brain health
A cup of coffee when you’re sleepy can wake you up quickly and energized. The caffeine in coffee binds to nerve cell receptors, helping you stay awake and think sharper.
In addition, drinking coffee may also help reduce the risk of Parkinson’s disease and Alzheimer’s disease, two of the world’s most common neurodegenerative diseases. Studies have shown that people who drink 2-3 cups of coffee a day have a 65% lower risk of Alzheimer’s disease and a 29% lower risk of Parkinson’s disease.
Coffee has many health benefits, but the following groups need to be especially careful when using it
1. Gastric patients
Coffee is a strong stimulant that increases the production of stomach acid and gastric juices, causing stomach ulcers to spread and possibly causing symptoms such as stomach bleeding or abdominal pain or diarrhea. Diarrhea, abdominal distension, and in severe cases, gastrointestinal diseases such as gastric ulcer may occur.
2. People who drink coffee “drunk”
Some people are very sensitive to caffeine and should definitely not drink coffee as it can easily get drunk. Symptoms of coffee poisoning include palpitations, palpitations, palpitations, sweating, and weakness in the limbs.
3. Pregnant and lactating women
Coffee is probably safe if pregnant women drink 2 or fewer cups of coffee a day. However, heavy drinking increases the risk of miscarriage, premature birth, and low birth weight babies.
Drinking 1-2 cups of coffee a day is safe for nursing mothers and babies, but large amounts of caffeine can irritate the gastrointestinal tract, causing sleep problems and irritability.
Therefore, if you are pregnant or breastfeeding, but still want to drink coffee, you need to ask your doctor about the allowed amount of coffee.
4. Patients with kidney disease
People with kidney problems or kidney failure should not drink coffee. Because the caffeine in coffee not only stimulates the brain, but also stimulates the function of the kidneys. Drinking coffee in people with kidney problems can make the condition worse.
It is also important to note that for most people, a safe coffee intake is 3-5 cups of coffee per day, with a maximum total caffeine intake of 400 mg. Therefore, people should not drink too much coffee in a day to avoid harm to the body.
