Does Coffee Have Health Benefits?

Coffee is a popular drink throughout the world and although it often contains caffeine, there are some important nutrients and antioxidants contained in your coffee cup.

Some studies show that people who drink coffee also have a lower risk of some illnesses. Let’s have a look at some of the health benefits.

  1. Increases energy

Caffeine is the most consumed “drug” in the world and it’s found in coffee. When you drink a cup of caffeinated coffee, the caffeine enters your bloodstream and travels to your brain and improves your energy levels and your mood.

That’s why it’s best to drink decaffeinated drinks before bed, otherwise, you could find yourself extremely alert and unable to sleep.

  2. Coffee contains essential nutrients

Coffee contains some essential nutrients including:

  • Vitamin B2
  • Vitamin B3
  • Vitamin B5
  • Potassium
  • Magnesium

If you’re looking for the best coffee nutritionally, then organic black fresh coffee has a high antioxidant content. However, dark roast blends are thought to have higher antioxidant levels compared to medium or light roast coffee blends.

  3. Coffee could boost metabolism

Some studies show that caffeine could help to boost our metabolism and may be beneficial for weight loss. That’s because it may promote the burning of fat in the body. However, more research is required to prove that caffeine could have benefits for our metabolism.

  4. Could protect against Alzheimer’s Disease

Alzheimer’s Disease is the most common neurodegenerative disease in the world and mostly affects people over the age of 65. Currently, there is no cure, but lifestyle factors such as eating a healthy diet and taking part in physical activity can help reduce the risk.

However, some research suggests that coffee could help lower the risk of Alzheimer’s Disease. One study carried out in 2012, analysed people with mild cognitive impairment and monitored their caffeine intake and their subsequent cognitive function for 2-4 years.

Researchers found that those who didn’t develop dementia had double the amount of caffeine in their blood compared to those who did develop dementia.

Can you drink too much coffee?

There aren’t currently any limits in the UK for coffee consumption but pregnant women are advised to limit their caffeine intake to 200mg per day, approximately 2 cups of instant coffee.

Consuming too much caffeine can cause side effects such as:

  • Dizziness
  • Tremors
  • Trouble sleeping
  • Headaches

Plus, caffeine is a diuretic, so will make you pee more. Inevitably, this means your body will be losing water, so it is essential to drink water to avoid dehydration.

Summary

There is some suggestion that coffee can have some health benefits but it’s essential to enjoy this popular beverage as part of a healthy, balanced diet.
