My morning coffee habit
I have a morning coffee habit.
It is black coffee every morning. I drink one cup a day, whether I have work or not, as a habit.
On days when I have to work, I choose a bitter coffee to wake me up and motivate me, and on days off, I choose a slightly sweeter, fruity coffee to relax and enjoy.
(To be honest, I don’t really know the difference in taste, I just enjoy the smell of the coffee when I brew it with drip coffee instead of instant coffee. ) So, I don’t try to choose which beans are from where, or freshly roasted, or grind the beans before brewing. (And I don’t even buy coffee beans from a specialty coffee shop; I just buy them at Cardi’s, which has a great aroma.)
) I have heard that there is a possibility of “cancer” in such a habit of drinking one cup of coffee a day, so I did my best to research and summarize it, especially since it is not related to my habit this time.

Carcinogenic Warning Label (California Proposition 65)
In California, a statute called Proposition 65 requires warning labels on products containing carcinogens and reproductive toxicants.
This statute was passed by referendum in 1986 and has been in effect since 1987.

Purpose of Proposition 65
The purpose of Proposition 65 appears to be to protect California citizens from health hazards caused by carcinogens and reproductive toxicants.
Specifically, the two main objectives are to
Inform citizens of the existence of carcinogens and reproductive toxicants
Encouraging businesses to reduce their use of these substances
Target Substances
There are approximately 1000 substances covered by Proposition 65, which is updated annually.
The main substances covered are
Carcinogens: asbestos, benzene, formalin, tobacco smoke, ultraviolet radiation, etc.
Reproductive toxicants: lead, mercury, arsenic, bisphenol A, phthalates, etc.

Warning Label Contents
Warning labels must include the following information
Warning statement: “This product contains chemicals known to the State of California to be carcinogens or toxic for reproduction.”
Target Substance Name: The name of the specific chemical
Website: Link to California State Government Website
Eligible Products
The products covered by Proposition 65 are very diverse. Specifically, they include
Food products: coffee, French fries, alcoholic beverages, etc.
Household goods: cosmetics, perfumes, detergents, etc.
Furniture: carpets, sofas, curtains, etc.
Toys: plastic toys, stuffed animals, etc.
Electronics: cell phones, computers, televisions, etc.

Corporate Response
It appears that companies selling products subject to Proposition 65 will be required to affix warning labels.
They will also need to provide information to state governments on the types and amounts of chemicals contained in their products.
Penalties for Violations
Violations of Proposition 65 may result in fines of up to $2,500 per day.

judgment
While Proposition 65 is an important statute that protects consumers, the following criticisms exist
Too many warning labels, which can be confusing to consumers
Too much of an economic burden on companies
Contains some substances that are not based on scientific evidence (the relationship between coffee and cancer is said to lack scientific evidence)
From our research, as of 2024, only California has this warning label attached.
When other states are added or when California stops using this label, we will cover it on this site.
The latest scientific findings
At this time, there is no reliable scientific evidence to support an increase in overall cancer risk from coffee drinking.
On the contrary, a number of studies suggest that coffee consumption is associated with a decreased risk of certain cancers.
This is great information for me.

Main Research Findings
Liver Cancer: many studies have shown that the higher the coffee intake, the lower the risk of developing liver cancer. (I also found a study that published “The effect on liver cancer is almost certainly suppressive.”)
Uterine Cancer: Women with higher coffee intake have been shown to have a lower risk of developing uterine cancer. (A study determined that the effect of coffee on uterine cancer is “likely.)
Colon cancer: Higher coffee intake has been shown to lower the risk of developing colon cancer, especially in women.
Pancreatic cancer: Some studies suggest that higher coffee intake is associated with a lower risk of developing pancreatic cancer, but further research is needed.
*However, some studies have found a slight association between coffee intake and risk of bladder cancer.
More information g on this.
However, this amount of information is currently limited and future studies will reveal the relationship.
Potential anticancer effects of coffee
Why does coffee prevent cancer?
The antioxidants and anti-inflammatory compounds in coffee may have a protective effect against cancer cell growth and DNA damage. The antioxidant is a substance called chlorogenic acid, which helps reduce inflammation and oxidation in the body.
This is enough to make me think that there is no reason not to drink coffee, not just one cup a day, but two or three!。

conclusion
Based on the current scientific findings I have examined,
Drinking moderate amounts of coffee is not thought to increase overall cancer risk.
On the contrary, there have been reports and studies showing that it may decrease certain cancer risks.
Based on these results, my personal opinion is that a cup of coffee a day does not seem to be a bad thing and is a good habit to continue. (This is just at this point in time.)
If I get sick and my doctor gives me a no-no, I will of course follow it.
There was a lot of information that recommended 2 or 3 cups of coffee a day.
I think I should drink a little more than that, but I don’t want to have to go to the bathroom more often at work, so I think I will continue to drink one cup a day for a while.
