Isn’t too much coffee bad for me?
Moderate to high coffee consumption may actually be protective against PCa
Research suggests that moderate to high coffee consumption may actually be protective against PCa progression because of coffee’s bioactive compounds. Coffee is rich in polyphenols, including chlorogenic acids and cafestol, which can reduce oxidative stress. These compounds can suppress inflammation that contribute to prostate tumor growth. An additional benefit is that coffee may improve insulin sensitivity and lower the risk of type 2 diabetes, which has been associated with aggressive PCa.
The Harvard Health Professionals Study of almost 48,000 men found that those who drank six or more cups of coffee per day (regular or decaf) had a 60% lower risk of lethal PCa than non-drinkers. Just be careful of the caffeine, especially if you’re also dealing with hypertension.
A Meta-Analysis (very strong research) by Chen and colleagues found that for every 1 cup/day increase in coffee consumption, there was a 1% reduction in overall PCa risk and a 7% reduction in aggressive cancer. Another Meta-Analysis by Wang et al. showed an inverse association between coffee consumption with PCa mortality, meaning the more coffee the participants ingested, the lower their risk of dying from cancer.
Obviously, this does not come without risk. Excessive caffeine may cause sleep disruption, anxiety, or worsen acid reflux. In addition, some unfiltered coffee (like French press or espresso) contains cafestol, which can raise LDL cholesterol. Keep in mind that added sugar or creamers will likely negate any benefits.
In my book, coffee is discussed in the same chapter as green tea. Nonetheless, I felt that sharing this graphic might be important to some readers of Prostate 180.
Both coffee and green tea offer significant health benefits, but their strengths differ: coffee is superior for cognitive stimulation, while green tea is richer in antioxidants and offers broader preventive effects on cancer, metabolic and cardiovascular health. Choosing one or both depends on individual health goals and tolerance to caffeine.
