Published in the journal Annals of Internal Medicine in 2017 showed that drinking coffee can reduce the rate of premature death.
This is the first study to show an association between coffee consumption and health and mortality risk across different ethnic groups, after excluding distinct confounding factors.
In one study, the American Institute of Cancer, the National Institutes of Health, and Northwestern University Feinberg School of Medicine, observed that people who regularly drink coffee live longer than those who don't. And people who drink a lot of coffee live longer than people who drink less coffee.
In the same study, the scientists reported that the numbers related to the benefits of drinking coffee include: 20% reduction in cancer risk, 20% reduction in type 2 diabetes risk, and 20% lower risk of heart disease. Parkinson's reduced by 30%, the risk of heart disease decreased by 5%.
So specifically, what are the health benefits of drinking coffee, and does coffee have any harmful effects that you need to be aware of? Let's learn more from the most up-to-date research on the benefits of coffee:
1. Coffee, caffeine and cardiovascular disease
There is some research showing that caffeine is a substance that raises blood pressure. But it does reduce the incidence of coronary heart disease, heart failure and atrial fibrillation. It is possible that the beneficial properties of coffee offset its mild negative impact.
In addition, research shows that coffee works to reduce bad cholesterol that builds up in blood vessels as well as markers of inflammation in the body.
2. Cerebrovascular accident and stroke
The benefits of coffee with blood vessels are maintained beyond the blood-brain barrier. One meta-study found that drinking 6 cups of coffee a day reduced the risk of stroke by 17%. In a subset of Swedish women, the figure goes up to 22-25%.
Another large analysis showed that drinking 1-3 cups of coffee per day had a preventive effect on ischemic stroke in the entire population. A Japanese study also found that the reward for those who maintained a coffee habit for 13 years was a 20% reduction in stroke risk.
3. Diabetes
Coffee seems to have a very positive effect on preventing increases in blood sugar, blood fats and overall body fat. Many studies have linked coffee drinking habits to glucose metabolism, inlusin-secreting effects, and a lower risk of diabetes.
Experts believe that the inverse correlation of coffee drinking with diabetes comes from the drink's anti-inflammatory properties and the antioxidant mechanism of chlorogenic acid found in coffee.
4. Cancer
Previous studies have linked the amount of coffee consumed per day with a reduced risk of certain cancers.
Accordingly, drinking more than 2.5 cups of coffee per day will reduce the risk of colorectal cancer, more than 3 cups of coffee per day will reduce the risk of basal cell carcinoma, more than 4 cups of coffee Each day reduces the risk of endometrial cancer, head and neck cancer, more than 5 cups a day reduces the risk of breast cancer, more than 6 cups a day reduces the risk of prostate cancer.
5. Brains
In addition to helping the brain stay alert and focused in the short term, drinking coffee also seems to have long-term benefits for the brain.
One study reported that patients with mild cognitive impairment were able to recover by drinking 3-5 cups of coffee per day. Another study found that caffeine has a memory-enhancing effect.
Studies in mice have shown that caffeine inhibits the secretion of amyloid-beta, a protein that may increase the risk of Alzheimer's disease. Coffee has long been thought to have the effect of preventing Parkinson's disease.
6. Depression
Research shows that coffee consumption promotes mental health and fights depression.
In one study, women who drank 2-3 cups of coffee per day had a 15% reduced risk of depression compared with those who drank only 1 cup per week. Those who drank four or more cups a day reduced that risk by 20 percent.
The short-term effects of coffee on mood may come from serotonin and dopamine activity. The long-term effects may be related to coffee's antioxidant and anti-inflammatory properties.
7. Liver disease
Drinking coffee can protect your liver from fatty liver disease, cirrhosis, hepatitis C and reduce the risk of liver cancer. People with a genetic predisposition to liver disease who don't drink coffee are more likely to get the disease than those who do.
8. And that's not all
Some studies show that drinking coffee can reduce dry eye syndrome, reduce the risk of gout, fight infections, and potentially even protect you from the antibiotic-resistant MRSA bacteria.
