We all know that fruit and vegetables are good for us, but did you know that recent research shows that they can actually help reduce the risk of dying prematurely? Does it sound too good to be true? Let's take a closer look at what the research says.
As you probably already know, fruits and vegetables contain vitamins, minerals and other important nutrients. But did you know that the beautiful colours of vegetables come from protective substances called antioxidants? In other words, eating colourful food is good for your health!
3 reasons to eat more fruit and vegetables
1. Fruit and vegetables keep you healthy
Recent research shows that fruits and vegetables can help reduce the risk of several different diseases1. So, how much is needed to stay healthy? Everything seems to be better than nothing. A study conducted in London shows that even smaller amounts of fruits and vegetables can help reduce the risk of suffering from diseases such as stroke, cancer and heart and vascular disease.1.
2. Fruit and vegetables can reduce the risk of dying prematurely
Researchers estimate that 7.8 million deaths could be prevented if we started eating 10 vegetables and fruits (800 g) a day. This relatively large amount helps lower both blood pressure and cholesterol. In addition, the same study shows that some fruits and vegetables can reduce damage to our DNA and reduce the risk of cancer1.
3. Eating fruit and vegetables will make you happier
Yes, you read right! A lot of research indicates that you will be happier if you eat fruits and vegetables. Scientists in England have seen a clear connection between fruit and vegetable consumption and mental well-being. According to the study, people who consumed the recommended amount of fruit and vegetables (500 g) each day felt significantly better than those who consumed too little2!
How to get enough fruit and vegetables
It’s recommended that we eat 500 g of fruit and vegetables every day3. However, most people, 8 out of 10, do not eat the recommended dose4. Are you one of those struggling to get enough fruit and vegetables? Maybe you wish there was an easier way? Then I think you should take a closer look at the dietary supplement supergreens!
Supergreens are a dietary supplement that makes it easy for you to get all the nutrients from fruits and vegetables! A good example is Fitnessguru’s Green Boost. It is a dietary supplement filled with vegan superfood that contains lots of antioxidants, vitamins, minerals and essential amino acids. Green Boost by Fitnessguru is a powder that you mix with water or juice. It is also possible to mix Green Boost with protein powder for an even healthier protein shake!

What are super greens and why are they so healthy?
First of all, supergreens are a supplement packed with nutrition from green vegetables. Green vegetables such as spinach, kale and broccoli have proven to be among the most nutritious vegetables21! It doesn't stop there! Generally, the best supergreens supplements also contain the algae chlorella and spirulina. These algae are packed with vitamins, minerals and antioxidants. In addition, there are several studies that show that chlorella and spirulina have many health benefits! The two algae act as powerful antioxidants, among other things5 6 and can help strengthen your immune system7 8 9. There are also studies showing that chlorella and spirulina can help improve your cholesterol levels10 11 12 13 14 and keep your blood pressure under control15 16 17. Spirulina has also been shown to improve muscle strength and endurance18 19.
Are there any disadvantages to supergreens?
As you can see, chlorella and spirulina contribute to providing many health benefits to supergreens. It seems that these algae are safe to use for most people. However, there are a few things that may be good to know before you decide to test the popular dietary supplement.
- A few people feel nausea and get an upset stomach after consuming chlorella20.
- Supplements may interact with some medications. Not sure what applies to you? Talk to your doctor!
- The nutritional content of chlorella can vary depending on the type of algae used, how it is grown and how it is produced.
