coffee(NaturalHealth365) Something that many people look forward to, in the morning, is a cup of fresh brewed coffee to boost energy. While studies have shown this popular beverage to be beneficial for health in many ways, contradictory information has arisen throughout the years about the negative effects of caffeine on the body.

But, wait, several new studies are suggesting that this dark black beverage should have its place in our diet – as there are many health benefits such as, reduced risk of mortality and chronic diseases such as cancer, heart disease, type 2 diabetes, and more.

Moderate coffee consumption reduces mortality risk

It should be noted that earlier studies have shown heavy coffee consumption to be associated with a higher risk of mortality. However, more recent studies have revealed that earlier research is inconclusive.

A more recent longitudinal study was released by the American Heart Association journal, Circulation. After reviewing 28 years of data and records of nearly 4.7 million Americans, coffee consumption has been shown to have positive effects associated with lower mortality rate.

According to the scientific data, a higher consumption of total coffee – whether caffeinated or decaffeinated – is associated with lower mortality risk.

Whether it’s caffeinated or decaffeinated, a ‘higher coffee consumption’ was connected to a lower death rate at the one to five cups per day range. Consumers experienced a lower risk of death from type 2 diabetes, certain cancers, cardiovascular disease, and neurological diseases.

Coffee consumption may protect against certain cancers in some people

Several new studies are showing coffee and coffee extracts reduce oxidative DNA damage that leads to carcinogenesis. According to several studies, the caffeine in coffee also contains phytochemicals that have been reported to exert antitumor, antiangiogenic, and antioxidant properties.

Whether caffeinated or decaffeinated, positive results have been detected in several forms of cancer, such as:

  • Breast cancer: Following more than 335,000 women for an average follow-up of 11 years, a large study published in Breast Cancer Research found that higher caffeinated coffee intake may be associated with a lower risk of postmenopausal breast cancer. For every 100-milliliter increase in caffeinated coffee intake, the risk decreased by four percent for estrogen and progesterone receptor negative breast cancers.
  • Colorectal tumors: Three cups of coffee per day reduced the overall occurrence of colorectal tumors, as reported by the European Journal of Cancer Prevention.
  • Endometrial cancer: Scientific Reports recently reported that just one cup of coffee per day can reduce the risk of endometrial cancer by 4 – 7 percent.
  • Liver cancer: The Gastroenterology journal reported coffee drinkers as having a significant risk reduction in hepatocellular carcinoma. By drinking two to three cups per day, risk was reduced by 38 percent. With more than four cups, reduction increased to 41 percent.
  • Malignant melanoma: The Journal of the National Cancer Institute reported a modest decrease in the risk of melanoma with four cups or less of coffee consumption.

Higher coffee intake may reduce other chronic diseases

Chronic liver disease: High levels of coffee consumption had a significant risk reduction of chronic liver disease, according to the Gastroenterology journal. Two to three cups per day reduced risk of death by 46 percent, while those who drank more than four cups per day reduced their risk by a whopping 71 percent.

Coronary heart disease: According to a study published in PLoS One, two cups of Italian-style coffee per day reduces risk of coronary heart disease. However, consumption was not associated with plasma lipid changes.

Neurological Diseases: Caffeine has been shown to be neuroprotective by antagonizing certain receptors in the brain which protect motor neurons from excitotoxicity. Additionally, chlorogenic acid in coffee may have clinical benefits for neurodegenerative diseases such as ischemic stroke, according to the Life Science journal.

Type 2 diabetes: While several studies show that high habitual coffee consumption is associated with reduced risk of developing type 2 diabetes, a study published in the Journal of Natural Products found that a specific bioactive substance found in coffee may contribute to prevention. After incubation with cafestol, insulin secretion and glucose uptake increased significantly.

So, should you drink coffee or not?

While these studies mentioned continue to support the beneficial effects of higher coffee consumption, possible advantages must be weighed against potential risks such as anxiety, tremors, palpitations, insomnia, and more.  Keep in mind, the health status of each person can vary greatly – especially when considering genetic tendencies or weaknesses.

If you’re not sure about coffee safety – talk to a qualified healthcare provider with lots of experience using natural therapies and nutrition to heal the body. And, above all, pay attention to how you feel (physically, mentally and emotionally) – whenever making any kind of diet or lifestyle change.

    There have been defenders of coffee in the natural health movement for years. Now, there is proof that they were right. The coffee bean has been around and it is a naturally grown product.

    I have seen very healthy coffee drinkers and have taken notice of a company that produces a brand called Bulletproof coffee. The people behind this company are looking at coffee for its benefits.

  • Lucy Joyce

    Does this mean I should start drinking coffee? If you have adrenal fatigue you have to be careful not to use stimulants. Coffee falls under that category.

  • Carolyn Basha

    People who drink coffee have a much less chance of becoming constipated. Many people have a laxative effect from drinking coffee.

    There is nothing wrong with a morning cup of coffee. It is only when you depend on it to keep you up throughout the day.

  • Arthur Johnson

    I will only use organic coffee, the chemicals used to process it are a problem.

  • Nelson H

    There are many coffee drinkers with the above health problems. It still comes down to what else you do. A good diet goes a long way and coffee can’t overcome a bad diet.

  • Cindy Arkin

    Finally an article that makes sense. There is no really bad thing it is how you use it. Coffee is such an example. People who indulge in a cup or two a day are not ruining their health.

  • Noreen P

    I am glad to hear that coffee has health benefits since half of all Americans drink it. Coffee is not only a past time it is ingrained in the American culture.

    Every get together we have in our community we serve coffee. If they didn’t we would have people complaining about the lack of it.

  • Abby L

    I think they are talking about plain coffee, not the sugar packed kind served at some known coffee houses. Most of the added ingredients probably negate some of the benefits.

  • Chuck Donovan

    One of the wrong reasons people get hooked on coffee is for the pick-me-up aspect. There is something wrong if the American public has to rely on an energy boost.

    Being healthy means having good energy throughout the day. The fault usually is in the diet and lifestyle. I wonder if a really healthy eater needs coffee to ward off these chronic conditions.

      Excellent point !!

  • Jimmy H

    My neighbor had anxiety attacks, because of drinking 7 to 11 cups per day. He had no idea it was from the coffee until he ran out and went cold turkey.

    There is too much of a good thing. The moral of the story is less is more. I would say no more than 4 cups a day and less would be better.

  • HealthIsPossibleAgain

    I’ve seen articles indicating that coffee is the second most pesticide ridden crop on earth. The first is tobacco. So, always buy and drink organic ONLY.
