Coffee

Coffee might be good for you. It could help lower the chance of getting type 2 diabetes and help with losing weight. Around the world, experts think people drink about 2.25 billion cups of coffee every day. Scientists have studied how coffee affects health conditions like diabetes, heart disease, bowel problems, and liver disease. They’ve found evidence that supports some claims but not at all of them. Coffee has some good stuff in it, like vitamin B2 (riboflavin), vitamin B3 (niacin), magnesium, potassium, and antioxidants called phenolic compounds. Some experts say these things in coffee might be good for the body in different ways. For more research you can also visit Wikipedia.

What is Coffee?

Coffee is a popular drink made from the roasted beans of Coffee fruits. It contains caffeine and chlorogenic acid. The caffeine in coffee works by stimulating the central nervous system, heart and muscle. Chlorogenic acid might affect blood vessels and how the body handles blood sugar and metabolism. People most commonly drink coffee to increase mental alertness. It is also used for diabetes, cancer, heart disease, high blood pressure, dementia, and many other conditions but there is no good scientific evidence to support most of these uses. Don’t confuse coffee with other caffeine sources such as green coffee, black tea, and green tea. Because these are not the same.

What is the Nutritional Value of Coffee?

A typical cup of black coffee, which is about 3.3 ounces, has only about 2 calories if you don’t add milk or cream. But if you add cream or sugar the calorie count goes up. Coffee beans have antioxidants called polyphenols. Antioxidants help protect your body from damage caused by waste products called free radicals. Free radicals can harm your body and cause inflammation, which is linked to conditions like type 2 diabetes and obesity. Some researchers in 2018 suggested that the antioxidants in coffee might help protect against metabolic syndrome. Even though scientists know that coffee beans have certain compounds, it’s still not clear how these compounds work in the body once you drink coffee. The main ingredients of coffee are caffeine, tannin, fixed oil, carbohydrates, and proteins.

What are the Health Benefits of Coffee?

Here are health benefits of coffee, such as:

Boosts Energy Levels:

Coffee has caffeine which is a substance that wakes you up and boosts your energy. It works by blocking a brain chemical called adenosine, which makes you feel tired. When adenosine is blocked, other chemicals like dopamine, which keep you alert, increase in your brain. In one study people who drank caffeine could cycle for longer and felt less tired compared to those who didn’t have caffeine. Another study showed that caffeine helped perform better, feel more energetic and be less tired.

Lower Risk of Types 2 Diabetes:

Some studies suggest that drinking coffee regularly might lower your chance of getting type 2 diabetes in the long run. One review of 30 studies found that for each cup of coffee someone drank every day, their risk of getting type 2 diabetes went down by 6%. This could be because coffee helps keep your pancreas working well. Your pancreas has cells called beta cells that make insulin to control your blood sugar levels. Also, coffee has lots of antioxidants and might help your body respond better to insulin, fight inflammation and manage how your body uses energy. These things are all important in preventing type 2 diabetes.

Could Support Brain Health:

Although some studies show mixed results, there’s evidence to suggest that coffee might help protect against certain brain disorders like Alzheimer’s disease and Parkinson’s disease. One review of 13 studies found that people who regularly drank caffeine had a lower risk of getting Parkinson’s disease. And for those who already had Parkinson’s, caffeine seemed to slow down how fast the disease got worse. Another review of 11 studies with over 29,000 people discovered that the more coffee people drank the less likely they were to get Alzheimer’s disease. Also, a few studies have shown that drinking coffee in moderation might lower the risk of dementia and losing cognitive abilities.

Promote Weight Management:

Some research suggests that drinking coffee might affect how your body stores fat and help keep your gut healthy, which could be good for managing weight. For instance, one review of 12 studies suggested that drinking more coffee might lead to less body fat, especially in men. Another study found that women who drank more coffee tended to have less body fat. Also a study showed that people who drank one to two cups of coffee each day were more likely to meet recommended levels of physical activity. Being more active can help with weight management.

Lower Risk of Depression:

Several studies suggest that drinking coffee might lower the risk of depression. One review of seven studies found that for each cup of coffee people drank daily the risk of depression decreased by 8%. Another study showed that drinking at least four cups of coffee a day was linked to a much lower risk of depression and psychological stress compared to having just one cup of coffee. Moreover, a study involving over 200,000 people found that drinking coffee was connected to a lower risk or death by suicide.

Could Protect Against Liver Conditions:

Several studies suggest that drinking coffee may be good for your liver and help prevent diseases. One study found that drinking more than two cups of coffee per day was linked to lower rates of liver scarring and liver cancer in people with liver disease. Other research shows that the more coffee people drink the less likely they are to die from chronic liver disease. Drinking one cup of coffee per day was associated with a 15% lower risk while drinking four cups per day was linked to a 71% lower risk. Another recent study discovered that drinking coffee was connected to less stiffness in the liver which is a sign of fibrosis, or the buildup of scar tissues in the liver.

Support Heart Health:

Some studies suggest that drinking coffee might be good for your heart. For instance, one review found that drinking three to five cups of coffee a day was linked to a 15% lower risk of heart disease. Another review of 21 studies showed that drinking three to four cups of coffee daily was associated with a 21% lower risk of strokes. Additionally, a study with over 21,000 participants found that drinking more coffee was linked to a significantly lower risk or heart failure. However, it’s important to note that caffeine in coffee can affect blood pressure levels. So, people with high blood pressure may need to watch how much caffeine they consume.

Could Increase Longevity:

Some studies suggest that drinking it might help you live longer because of its potential health benefits. For instance, one review of 40 studies found that drinking two to four cups of coffee every day was linked to a lower risk of death, no matter a person’s age, weight, or how much alcohol they drank. Similarly, another study with 1567 participants found that drinking caffeinated coffee was connected to a lower risk of death after 12 and 18 years. Also, having at least one cup of coffee a day was linked to a lower risk of dying from cancer. In an interesting test-tube study, coffee was found to extend the life span of yeast by protecting against damage from harmful substances and DNA damage. However, more research is needed to see if these benefits also apply to humans.

May Enhance Athlete Performance:

Athletes often use it to boost their performance and energy levels. A performance enhancer like coffee is called an ergogenic aid. One review of nine studies found that drinking it before working out helped people endure longer and feel like they were working less hard compared to those who didn’t drink it. In another study involving 126 older adults, drinking coffee was linked to better physical performance and faster walking speed, even after considering things like age, belly fat, and how active they were. Moreover, a big review found that having a moderate amount of caffeine could slightly improve how much power you have and how fast you finish a race. But the results varied, so researchers said caffeine might affect people differently.

What are the Risks Factors of Coffee?

Drinking a lot of it can also have some adverse effects. These may include the following:

  • Bone fractures
  • Complications during pregnancy
  • Endometriosis
  • Gastroesophageal reflux disease

  • Worsened symptoms of certain mental health conditions like schizophrenia or bipolar disorder.
  • Higher risk of suicide.
  • It-related disorders like caffeine overdose, caffeine induced anxiety and caffeine related sleep disorders.

What is the Difference Between Coffee and Tea?

Coffee and tea both have caffeine so they can offer similar benefits, risks, and side effects. But the amount of caffeine in each drink can vary. A typical 8 ounce cup of it has around 95 mg of caffeine, while black tea has about 48 mg, and green tea has around 29 mg. People may experience different effects depending on whether they prefer it or tea and how much they drink. A 2018 study compared the positive effects of drinking it and tea and found some differences:

Coffee:

Drinking coffee might lower the risk of dying from heart disease and cancer, especially for women. It could also reduce the risk of dying from respiratory infections, especially for men. For women, drinking only coffee or up to 40% tea might be linked to the lowest risk of dying from different causes. But drinking more tea than coffee might increase the risk of morality.

Tea:

Drinking tea might lower the risk of dying from heart disease and cancer, especially for men. Men who drink tea between 30% and 50% of the time might have the lowest risk of dying compared to those who only drink coffee. The study’s main finding is that both coffee and tea have other benefits but the effects depend on how much you drink, and these effects can differ between men and women. The varying impact based on gender might be connected to how coffee influences sex hormones.

Caffeine and Antioxidants What to Know About It?

Opinions about it vary widely; some see it as a health pick up while others view it as addictive and harmful. However, when we look at the research most studies suggest that it is good for you. For instance drinking it has been linked to a lower risk of type 2 diabetes. liver disease, and Alzheimer’s. Many of the health benefits of it might come from its high levels of antioxidants, which help protect your body from damage. In fact, research shows that it is one of the main sources of antioxidants in our diets.

Loaded with Several Powerful Antioxidants:

Your body is constantly protected from harmful molecules called free radicals, which can harm important substances like proteins and DNA. Antioxidants can help fight off these free radicals, protecting against aging and many diseases, including cancer, that are partly caused by oxidative stress. It contains several powerful antioxidants like hydrocinnamic acids and polyphenols. These antioxidants are effective at neutralizing free radicals and preventing oxidative stress. Polyphenols in coffee may also help prevent conditions like heart disease, cancer, type 2 diabetes. 

The Biggest Dietary Source of Antioxidants:

Most people get about 1-2 grams of antioxidants per day, mainly from drinks like coffee and tea. Beverages contribute a lot more antioxidants to the Western diet than foods do. In fact, 79% of dietary antioxidants come from drinks while only 21% come from food. This is because people tend to drink more antioxidants-rich beverages than eat antioxidant-rich foods. Even though it ranks 11th on the list of antioxidants-rich foods, it provides a significant amount of antioxidants overall, especially since people tend to drink multiple cups of coffee each day. In studies from Norway and Finland, it was found to be the biggest source of antioxidants providing about 64% of people’s total antioxidants intake. On average, people in these studies drank about 2-4 cups of it per day. Similar findings were seen in studies from Spain, Japan, Poland, and France, where it is the main dietary source of antioxidants. 

Linked to a Reduced Risk of Many Diseases: 

It is linked to a reduced risk of many diseases. Such as:

  • Its drinks have a 23-50% lower risk of type 2 diabetes, with each daily cup associated with a 7% reduced risk. 
  • It seems to be good for your liver, as drinkers have a much lower risk of liver cirrhosis. 
  • It may lower your risk of liver and colorectal cancer, as well as reduce the risk of heart disease and strokes.
  • Regular consumption of it may lower your risk of Alzheimer’s and Parkinson’s disease by 32-65%. 
  • Some studies suggest that it may also benefit mental health, as women who drink coffee are less likely to become depressed or die by suicide. 
  • Overall, drinking it has been linked to a longer lifespan and up to a 20-30% lower risk of premature death. 

However, it’s important to note that most of these studies are observational, meaning they can’t prove that it directly caused the reduction in disease risk, only that drinkers are less likely to develop these diseases.
