Researchers have been investigating the links between coffee and cancer for decades. And now the coffee-cancer connection is in the news again. A California court ruling last week about a coffee warning related to a chemical formed during the roasting process called acrylamide has raised questions among consumers.
According to the American Cancer Society1 in 8 women in the United States will develop breast cancer. Fifty-four percent of adults in the United States drink coffee every day, according to the Harvard School of Public Health. The average coffee drinker consumes three cups of it each day.
It's good news for caffeine addicts who find themselves craving a coffee at all times A study carried out by researchers in Spain found that diets rich in phenolic acids - found in coffee - can protect against the risk of post-menopausal breast cancer. Phenolic acids are also found in a number of plant-based foods, including citrus fruits, oats, rice, blueberries, whole grains and red wine.
Women who eat and drink coffee, fruit and vegetables may have a boosted defence against breast cancer, according to new research. A study found that a diet full of phenolic acids reduced the risk of post-menopausal breast cancer. Rich sources include raspberries, blueberries, apples, citrus fruits, plums, onions, cocoa and wholewheat, rice, corn and oats - as well as coffee and red wine.
Coffee may do more than give a caffeine boost it could also reduce the risk of developing a particular kind of breast cancer, according to a new study. Women who drink five or more cups of coffee a day are 57 percent less likely to develop estrogen receptor-negative breast cancer than women who drink less than a cup of coffee a day, said study researcher Jingmei Li, of the Karolinska Institute in Sweden. Estrogen receptor-negative breast cancer is just one kind of breast cancer and is characterized by its lack of estrogen receptors, meaning its growth is not governed by estrogen.
Coffee and cancer have had a rocky relationship over the years. Coffee was once recklessly touted as a cancer treatment and later declared a carcinogen. Today, new studies indicate it may help prevent certain types of cancer.

Just decades ago doctors and health professionals were warning about the dangers of having too much coffee because of the risk that caffeine was thought to have on the body. However, the last decade has shed a lot of light on the health benefits of coffee and its relationship to cancer. Many decade or more long studies have been coming to a close and the results have been changing everything the medical profession thought they knew about coffee and how it influences the risks of getting cancer.
For most types of cancer, coffee appears either to decrease risk of cancer, or to have no effect on cancer risk at all. Even in countries with very high intake of caffeine from coffee, such as Scandinavian countries, research does not support a link between coffee or caffeine and cancer risk. The only exception may be lung cancer.
