Pros and cons about coffee consumption

With its wealth of minerals and vitamins, and antioxidants, coffee is a beverage with many beneficial effects. Effectively fighting against the free radicals responsible for premature aging of the body’s cells, coffee strengthens the immune system and reduces the risk of many diseases such as cardiovascular disease, diabetes, Parkinson’s disease, and several types of cancer (prostate, liver, mouth, etc.). According to a recent study, drinking a cup of coffee a day would increase the antioxidant capacity of the plasma.

As for caffeine, coffee is one of the main sources (together with tea), it acts as a stimulant that increases alertness, improves concentration and memory, and relieves migraines and headaches. But like all foods, the watchword remains moderation.

In fact, consumption of more than 3 cups of coffee a day can have a negative effect on your health. This excessive consumption increases the risk of conjunctivitis, cholesterol, hypertension, tachycardia (heart palpitations), gastric irritation and sleep disorders. In addition, pregnant women should not consume it because it increases the risk of miscarriage and cot death. Although coffee has a protective effect against some types of cancer, it increases the risk of other cancers such as bladder, colon and rectum.

How coffee influences the breasts and the risk of breast cancer?

Dr Helena Jernström, professor of oncology at Lund University in Sweden, wanted to analyze the effect of daily consumption of three cups of coffee per day on breast size and risk of breast cancer. Performed on 270 women, this study showed that among those with a variation in the CYP1A2 gene (almost half of the women involved in the study), consumption of three cups of coffee a day was linked to a smaller size breasts, and a lower risk of breast cancer or a later onset of the disease.

In fact, coffee influences on the metabolism of female hormones, estrogen, reducing their secretion. Since they are responsible for the development of sexual organs and breasts, their decline also reduced the size of the mammary glands.


With regard to breast cancer, it is hormone-dependent in most cases, as ovarian, uterus and prostate cancer. Thus by decreasing the secretion of the female hormones, the risk of developing breast cancer is greatly reduced, and the risk of recurrence reduced. Moreover, another study by the Karolinska Institute, whose findings were published in the journal Breast Cancer Research, also confirmed that consumption of three cups of coffee per day reduced the risk of breast cancer.

Thus, drinking coffee is not only a way to wake up or fight declining concentration during the day but is also a way to stay healthy and protect yourself from breast cancer. Provided, of course, choose an organic coffee and not consuming it in excess!
