Limitation of studies
But let's take a step back and consider that while this study offered us an idea, it was observational and just because there is a correlation between coffee consumption and longevity, it doesn't mean that coffee is the only reason or cause for that.
Studies like these take into account multiple factors, but cannot yet determine causality, which means that coffee may not have been what caused certain populations to improve longevity.
It is important to also look at the currently recommended upper limits we have for caffeine consumption, and ask if any of the people who consumed more than 8 cups a day had other side effects that were not considered.
Coffee is not perfect
After a big moment of glory, it's important to know that coffee comes with its fair share of unpleasant side effects for many of us.
Caffeine activates our "fight or flight" response with the release of adrenaline which, as a result, increases our energy. But, for sensitive people, this can trigger irritability, anxiety, and anxiety.
Because it stimulates the nervous system and increases the heart rate, caffeine can also increase blood pressure, so you should limit its consumption if you have high blood pressure.
Also, sensitive people can experience insomnia if they drink too much caffeine or take it too close to bedtime, as it can take up to 9 hours for your body to fully metabolize it.
It is also not recommended for people with iron deficiency, as it can reduce iron absorption (or must be separated from meals), and for anyone with digestive problems or GERD.
Enjoy your coffee, but watch your portion size
In the end, whether you drink coffee or not, having a glass of wine with dinner or a bite of dark chocolate shouldn't depend solely on the latest and greatest study.
How much coffee is it okay to drink?
If you like coffee then that's perfectly fine, as it may be offering some good health benefits. It is important to know that although some studies may show that up to 8 cups of coffee are beneficial, this is more than double the daily amount recommended by the FDA.
They recommend no more than 400 mg of caffeine, or three 8-ounce cups of brewed coffee per day.
A standard small serving of coffee, for example, a short coffee made at Starbucks contains 130 mg of caffeine, while the venti (large) has around 340 mg, which is almost at the upper daily limit for caffeine.
Also, keep in mind that lighter roasts tend to contain more caffeine.
Organic coffee is always recommended, as I know it is sourced ethically and more sustainably. To get the most out of your cuppa, skip the sugar and use milk or milk alternatives in moderation. You can really appreciate the flavor when you have a bold, pure cup with nothing added.
If you are a decaffeinated drinker, choose coffee made with natural caffeine extraction methods, such as the Swiss water process versus chemical solvents. Organic growers generally use this method.
It is important to pay attention to your own body and how it reacts to drinking too much coffee. If you feel irritable, anxious, or agitated, or know that you are sensitive to the effects of caffeine, then opt for other beverage options.
There are many healthy and delicious coffee alternatives, such as green and white tea that have an incredible antioxidant profile, rooibos tea with low tannin content and a heavenly aroma, and coffee leaf tea that provides sustained energy and only 20 mg of caffeine per cup.
So if you think that 4-5 or 6-7 or even 8 cups sounds too much for some people, you are probably right. Most of us are familiar with our coffee tolerances, so we need to take that into account.
In general, it seems that coffee is something we can enjoy on a daily basis, and if we normally drink more than one with no ill effects, it is something we don't have to worry too much about.
You drink a lot of coffee? How many cups of coffee do you have per day?
Low blood sugar, also known as hypoglycemia, can be a dangerous condition. Low blood sugar can happen in people with diabetes who take medications that increase insulin levels in the body. Taking too much medication, skipping meals, eating less than normal, or exercising more than usual can lead to low blood sugar for these individuals. Blood sugar is also known as glucose. Glucose comes from food and serves as an important energy source for the body. Carbohydrates foods such as rice, potatoes, bread, tortillas, cereal, fruit, vegetables, and milk are the body’s main source of glucose. https://ipsnews.net/business/2021/02/06/gluconite-supplement-reviews-doe...
