A Harvard study of over 50,000 women found that the risk for depression declined with increasing coffee consumption. Black coffee is also associated with an association that helps prevent type 2 diabetes. A study found a 12% risk reduction after drinking two cups of coffee a day and this association was stronger in women than men.
Studies have shown that people who regularly drink coffee have an 11% lower risk of developing type 2 diabetes than non-drinkers due to the ingredients in coffee which affect hormone levels in metabolism. A meta-analysis of 2017 concluded that people who drink four to six cups of caffeinated or decaffeinated coffee a day are at a lower risk for metabolic syndromes, including type 2 diabetes.
A 2017 study published in the BMJ Open found it is possible to reduce risk of cancer by 20 percent if you drink one cup of coffee a day, by 35 percent if you drink two and 50 percent if you drink five cups a day because caffeine inhibits the proliferation of cancer cells. Studies have shown that four or more cups of coffee a day can reduce the risk of depression by up to 20%. Drinking coffee is linked to preventing cognitive decline, including a lower risk of developing Alzheimer’s, a research report has found.
Studies have shown that coffee can protect against certain cancers such as breast, colon, cervical and prostate cancers, as well as heart and Parkinson’s disease. A 2014 study published by the American Association for Cancer Research found that coffee drinking can help reduce the risk of melanoma, which causes the most deaths from skin cancer, according to the American Cancer Society. Another study published in the Journal of the National Cancer Institute found that the risk of melanoma decreased with coffee consumption, with the risk of it decreasing with each brisk cup consumed.
Coffee and heart health A 2012 study concluded that those who drink coffee in moderation and eat two servings a day are better protected from heart failure. In a 2015 study published in the Journal of Heart Research, people who drink three to five cups of coffee a day have a lower risk of clogged arteries and heart attacks. A study conducted in Japan found that men who drink at least three cups of coffee a day have a 24% lower risk of dying of the disease.
A study published in the Annals of Internal Medicine issue of June 17, 2008 showed that women who drink coffee have a lower risk of dying from cancer, heart disease and other factors that promote a longer lifespan. Another study, published in the New England Journal of Medicine, found that coffee drinkers have a lower risk of dying early from diseases such as diabetes, heart disease and some cancers.
Researchers have found that coffee can help reduce the effects of the ageing on motor skills which has been shown to reduce the risk of dementia, Alzheimer’s and Parkinson’s. A review of research has found that studies have shown that drinkers of coffee have a 30% reduced risk of Alzheimer’s compared to non-coffee drinkers. A study has shown how important this is as you get older, that drinking 3 to 5 cups of coffee in middle age can reduce the risk of Alzheimer by 64 percent compared to those who drink less coffee.
In addition to caffeine, coffee can help control movement in people with Parkinson’s, according to a 2012 study. One study showed that coffee can reduce prostate cancer risk by 20% in men and cervical cancer risk in women by 25%.
Thanks to 30 years of studies, researchers have found that non-smokers who drink two cups of coffee a day have a reduced risk of colorectal, liver and breast cancer in women. A study of 489,706 people found that people who drank four to five cups of coffee a day had a 15% lower risk of colorectal cancer (43). Coffee can also protect against cirrhosis of the liver in people who drink four or more cups of coffee a day with 80% lower risk of (35, 36, 37).
Hu says that moderate coffee consumption (1-2 cups a day) is associated with a lower risk of Type 2 diabetes, heart disease, liver and cervical cancer, Parkinson’s disease and depression. Recent research has shown that coffee drinkers do not appear to have higher heart problems or cancer risk than those who don’t drink coffee if they correctly adjust the interference factors. A 2017 study in the Annals of Internal Medicine used data from a multi-ethnic cohort study to show that people who drink coffee have a lower risk of dying from heart disease and strokes, diabetes, kidney disease and cancer.
Researchers collected data from more than 48,000 people in 2014 and found that those who increased their coffee intake for four years from one cup a day to 11% had a lower risk of diabetes type 2 than those who did not increase their coffee intake.
A meta-analysis rounded out 30 studies that found that the risk of diabetes for type 2 diabetics decreased with a 6 percent increase in coffee consumption per cup per day. In a 2015 study published in the Journal of Clinical Cancer Research, researchers found that breast cancer patients treated with the tamoxifen had half the risk of relapse when drinking two cups of coffee a day compared to those who drank less or no coffee at all.
Coffee whose main active ingredient is caffeine, has been linked to a reduced risk of all types of diseases, including Parkinson’s, heart disease, type 2 diabetes, gallstones, depression, suicide, cirrhosis, liver cancer, melanoma and prostate cancer. Drinking coffee regularly has been shown to help reduce the risk of developing Alzheimer’s disease and dementia later in life.
