Harmful Effects Of Chemical Solvents Used In Decaf Coffee

Does Caffeine Raise Blood Sugar? – by Dr Sam Robbins

The most common method for decaffeinating the coffee beans uses chemical solvents that may leave a residue on the coffee seeds. Soaking the coffee seeds in several chemical solvents such as methylene chloride and ethyl acetate for about 10 hours may be the reason for this. The beans are steamed again to remove most of the solvents. Be known that the FDA allows residues of these solvents to remain on the decaf coffee beans even after roasting.

Its up to you to decide whether the trace elements of these chemicals should be inside your morning coffee or not. Consuming methylene chloride and ethyl acetate on a regular basis will vastly increase a persons chances of getting a serious disease such as cancer. The industrys marketers never mention this, and they know what happens when the knowledge is made public.

How Much Caffeine Is Too Much

It only takes about 200 milligrams of caffeine to affect your blood sugar. Thatâs the amount in about one or two cups of brewed coffee or three or four cups of black tea.

You may be able to handle more or less caffeine. People can have different reactions to the drug. Your response depends on things like your age and weight.

How much caffeine you usually get may also play a role. People with diabetes who are regular coffee drinkers donât have higher blood sugar levels than those who arenât. Some experts think your body gets used to that amount of caffeine over time. But other research shows that caffeine could still cause a spike, even if you always start your day with a cup of joe.

To find out if caffeine raises your blood sugar, talk to your doctor or a dietitian. You might test your blood sugar throughout the morning after you have your usual cup of coffee or tea. Then youâll test after you skip the drink for a few days. When you compare these results, youâll know if caffeine has an impact.

The Theory Behind Coffee Reducing The Risk Of Type 2 Diabetes

Lets look first at why some researchers believe drinking coffee can lower the risk of developing diabetes.

One study of more than 12,000 people aimed to prove that the metabolic effects of coffee may reduce the possibility of diabetes.

After making adjustments for varying factors including:

  • Body mass index
  • Tea drinking

The study found coffee drinking showed positive effects on blood glucose levels.

In observational studies in people who have not been diagnosed with diabetes, coffee helped with reducing blood sugar and insulin levels the main risk factors for diabetes.

Studies show that drinking regular or decaf coffee on a daily basis can lower your risk of developing diabetes by 23 to 50 percent.

Other Fasting Blood Tests

Some other blood tests may require fasting too, according to Mercy Health. These can vary, however, so you’ll need to check with your doctor before your test. These tests usually include:

  • Anemia .
  • Kidney function .
  • Liver disease .
  • Vitamin B12 levels.

Remember, if you’re having a blood test for anything other than what’s been discussed above, you probably can go ahead and have your morning coffee and breakfast before your blood is drawn. But remember to always check with your doctor for detailed instructions, and follow those instructions exactly for the best results.

If you don’t have diabetes, the Mayo Clinic says drinking coffee shouldn’t noticeably affect blood sugar levels. Most healthy young adults can safely take in up to 400 milligrams of caffeine a day, which is more than the typical caffeine found in two 8-ounce cups of coffee.

If you do have diabetes, however, caffeine may affect your blood sugar levels. Caffeine may raise blood sugar for some diabetics, while it may lower blood sugar for others. Caffeine affects everyone differently, the Mayo Clinic says.

There aren’t a lot of clinical studies measuring the effects of coffee on a blood glucose test. A small study of coffee drinkers in the September 2012 edition of the journal Metabolism measured the effects of caffeine from espresso coffee. It found only marginal differences in glucose measures between coffee drinkers and noncoffee drinkers.

    How Drinking Coffee First Thing After Night Of Poor Sleep Impacts Blood Sugar

    Does coffee raise blood sugar?

    Physiologists at Bath examined 29 men and women after each of them experienced three distinctly different nights of sleep. In one experiment, the participants enjoyed a normal night of rest. This was followed by a sugary drink which roughly equals the calories eaten during breakfast.

    During the next two experiments, each volunteer was woken up every hour throughout the night to create a disrupted sleep. In one instance, the participants were given the same sugary drink after waking up. After the other bad sleep, researchers gave the group a strong black coffee 30 minutes before having their sugar. A blood test was then taken following each night of sleep and the drinks each person consumed.

    The results show that one good or bad night of sleep makes little difference in a persons blood sugar/insulin responses. Researchers note that previous studies link several nights of insomnia to metabolic issues, but add a single incident where you cant fall asleep doesnt carry the same weight.

    When coffee enters the picture, thats when the body sees a drastic change. Study authors report participants drinking coffee right after a bad night of sleep increased the blood glucose response to breakfast by around 50 percent.

    We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee intuitively the more tired we feel, the stronger the coffee, Prof. Betts explains.

    So What Should You Do

    • If caffeine is part of your current routine, either in your morning coffee or before a workout, be aware that it is likely decreasing your acute insulin sensitivity. Try not to pair it with high-carb meals.
    • Given that the apparent benefits of long-term coffee consumption appear to outweigh the short-term effects , you probably dont need to cut it out.
    • Switching to decaf appears to offer many of the same benefits but with a lesser short-term effect than regular coffee.
    • If youre not a coffee person, dont start drinking coffee just for the long-term metabolic benefits. You can get the same beneficial chlorogenic acids through several fruits and vegetables, including apples, artichokes, carrots, and tomatoes. Drinking green tea also appears to have long-term positive effects.
    • Remember to avoid adding sugar or artificial sweeteners to your coffee, and skip the sugary energy drinks.

    Does Coffee Raise Blood Sugar

    Does Decaf Coffee Raise Blood Sugar

    Most of the impact coffee has on blood sugar levels comes from caffeine, but one study showed an acute rise in blood sugar after drinking decaffeinated coffee. The study concludes that drinking decaffeinated coffee increases blood sugar levels in the short term but to a lesser extent than drinking caffeinated coffee.

    Drinking both regular and decaf coffee can actually help lower a persons risk of developing diabetes in the long term. The short-term spike in blood sugar seems to be a transient effect and doesnt change the fact that drinking coffee can reduce the risk of developing diabetes.

    Caffeine And Insulin Resistance


    A study consisting of 10 people with type 2 diabetes set out to determine the impact of regular caffeine consumption on overall insulin levels.

    All participants were regular coffee drinkers, consuming about 4 cups of coffee per day, but they all stopped drinking coffee during the study. Then half of them were given capsules containing 250 mg of caffeine, and the other half were given placebo pills containing zero caffeine.

    The result, according to the study: On the days the patients took caffeine, their bloodsugar levels were 8% higher. And after every meal including dinner their blood sugar spiked higher than it did on the day they had no caffeine.

    Does this mean people with diabetes shouldnt drink coffee and other caffeinated beverages? Not necessarily. It means we should look closely at our caffeine consumption and moderate it just like we would with other things that impact our blood sugar levels.

    Just because black coffee and green tea contain zero calories doesnt mean we should drink them without limits. Instead, caffeine should ideally be something we consume carefully and set personal limits around for the sake of our overall diabetes health.

    How Does Caffeine Affect Your Blood Sugar

    A growing body of research suggests people with type 2 diabetes react to caffeine differently. It can raise blood sugar and insulin levels for those with the disease.

    One study looked at people with type 2 diabetes who took a 250-milligram caffeine pill at breakfast and another at lunchtime. Thatâs about the same amount as drinking two cups of coffee with each meal. The result: Their blood sugar was 8% higher than on days when they didnât have caffeine. Their reading also jumped by more after each meal.

    Thatâs because caffeine can affect how your body responds to insulin, the hormone that allows sugar to enter your cells and get changed into energy.

    Caffeine may lower your insulin sensitivity. That means your cells donât react to the hormone by as much as they once did. They donât absorb as much sugar from your blood after you eat or drink. This causes your body to make more insulin, so you have higher levels after meals.

    If you have type 2 diabetes, your body already doesnât use insulin well. After meals, your blood sugar rises higher than normal. Caffeine may make it tougher to bring it down to a healthy point. This may lead to too-high blood sugar levels. Over time, this may raise your chance of diabetes complications, like nerve damage or heart disease.

    Ways To Combat The Coffee Spike

    There are many ways to help combat the blood sugar spike from coffee, including:

    • Try not drinking coffee first thing go for a 20-minute walk to combat the dawn phenomenon before you imbibe
    • Switch to decaf, or even half-caf
    • Cut down on your overall consumption
    • Do not drink coffee late in the day , so it does not negatively affect your sleep, and thus insulin resistance
    • Drink only black coffee, cold brew coffee, or coffee with a touch of dairy or non-dairy milk, cream, or half-and-half
    • Do not add syrups or sugar to your coffee opt for stevia instead
    • Add vanilla extract, cinnamon, or sugar-free syrups to your coffee for extra taste
    • If you regularly spike, even from black coffee, aim to pre-bolus before a cup, taking a dose for your coffee 10-15 minutes before drinking
    • Get some morning exercise in immediately after drinking a cup to help curb the spike
    • Talk with your doctor about additional strategies to incorporate coffee into a healthy diet

    The routine of a morning cup of coffee is essential to millions of people around the world, but a blood sugar spike is never enjoyable. Incorporating some of these strategies can help you mitigate the negative effects on blood sugar, while still allowing you to enjoy what you love! A little planning and preparation can make all the difference. And thats definitely something to celebrate. Cheers!

    Do You Need More Insulin For Coffee

    To better determine coffees impact on your blood sugar, create a simple experiment on a morning when you wake up with an in-range blood sugar. Drink a cup of coffee and see where your blood sugar goes during the 1 to 2 hours after that cup of coffee.

    Many people simply find they need 1 unit of fast-acting insulin with a cup of coffee.

    Or you could test your bodys response to coffee by removing coffee from your morning routine for a few days. Did your insulin needs drop? Were your blood sugars easier to manage? If so, that doesnt mean you cant go back to drinking coffee, but it does tell you that you need insulin to help your body deal with the effects of coffee.

    It also tells you that limiting your coffee intake is likely a good idea!
