How Many Servings Of Fruits And Vegetables A Day?

How Many Fruits and Vegetables Should You Be Eating Daily?

You have probably heard of ‘five-a-day’ somewhere before. It’s the number of fruits and vegetables that you are encouraged to eat every day for good health. But where does it come from and is there any good evidence that just eating 5 fruits and vegetables per day is enough for optimal health?

Even with this advice, many people are not eating that many fruits and vegetables every day. A survey conducted in 2014 showed that 70% of UK adults are eating less that five portions of fruits and veg, and so there is still a lot of work to do to change people’s eating habits.

Education from a young age is going to be one of the most effective ways to deal with this problem. If nothing is done, then it will become a much bigger issue. Diabetes for example is one of the fastest growing chronic conditions in the world and is primarily caused by diet. It can also be effectively reversed by diet if the diet is changed within a few years of being diagnosed.

Eating Five Servings Of Fruit And Vegetables Per Day Is Not Enough

Five portions of fruit and vegetables only adds up to 400 grams! The British Dietetic Association labelled the ‘5-a-day’ campaign a massive success. I’d call it a massive failure. First of all I think that 400 grams of fruit and vegetables a day is way too little to make a meaningful difference. And secondly, only 30% of adults in the UK even manage to eat 5 a day. And one of those five a day probably includes the tomato on pizza!

Another issue with eating so little fruits and vegetables is that the rest of the diet is usually overwhelmingly bad. To get the best health and cut the risk of disease, you really have to start removing a lot of the processed and refined foods and add even more healthy foods.

At minimum, people should be eating at least 10 portions of fruits and vegetables a day. Imperial College published an article earlier this year showing that 800 grams of fruits and vegetables per day could prevent millions of premature deaths.

You number you need to aim for at minimum is ten portions of fruits and vegetables per day. It’s common for people who are eating a raw food diet or calorie restricted diet to consume way more than this number. You want to tip the balance where the vast majority of the food you eat is healthy, and then just treat yourself every now and then to something small if you feel the need to.

Aim for Variety In Your Diet: Eat Different Coloured Foods 

There are many different types of fruits and vegetables which provide different health benefits. This is one of the reasons why I think 5 a day was is not enough. To get the benefits of these foods, you must be consuming them on a regular basis and also have variety.

What I do is have a staple of about 5 – 7 different fruits and vegetables, then rotate other foods so I’m not always eating the same thing every day. It’s not uncommon for me to have 10-15 different fruits and vegetables each day.

The staples in my diet include:

  • 1 whole Avocado
  • 1 large Banana
  • 1 Red Apple
  • Spinach (150 g)
  • Blueberries (200 g)
  • Broccoli (100 g)
  • 1 Kiwi

Once you create a foundation of staple foods, then you can build from that and experiment by including other foods in your diet. You could also include things like nuts, olive oil, limited amount of whole grains, and legumes into your diet. If you eat the same staple foods every day, then no matter how the rest of your day goes, at least you’ll have had better nutrition than most people probably get in a week! You should always aim to eat the highest quality foods, but sometimes that isn’t always possible.

Below are some ideas of what colour foods you should be eating and some of the benefits they might provide.

GREEN FOODS

Chlorophyll is what gives certain foods their green colour like spinach and kale. These leafy green vegetables highly nutritious and low calorie and should be a staple of your diet. They are typically high antioxidants like beta carotene, lutein, and zeaxanthin. They are also usually high in vitamin C, Folate and Vitamin K.

Benefits: Great for your eyesight and your skin. Beta carotene help provide some vitamin A and improves immune function.

Kale is also a great source of sulforaphane, which improves detoxification in the body and may prevent various types of cancers. According to some research, foods like spinach might also help improve muscle energy and function because of its high levels of nitrates.

RED, PURPLE, AND BLUE FOODS

Anthocyanins and in some cases Lycopene are responsible for the colour of these foods. Foods high in these are blueberries, cranberries, red cabbage, and tomatoes.

Benefits: These antioxidants may help improve eyesight, improve brain function, protect against cancer and infections (UTI). Lycopene has also been found to slightly reduce sun damage when exposed to UV rays.

YELLOW AND ORANGE

Beta Carotene is mainly responsible for the colour of these foods. Foods high in beta carotene include: sweet potatoes, yellow bell peppers, papaya, butternut squash. 

Benefits: Improve skin protection against free radical damage and possibly improve attractiveness according to some research. Beta carotene can also be converted to Vitamin A by the body (some people convert better than others). Natural beta carotene found in fruits and vegetables may also prevent certain types of cancer and improve the immune system.

WHITE

Anthoxanthin is (partly) responsible for the colour of foods such as cauliflower, onions and garlic. 

Benefits: These foods may lower the risk of heart disease and cancer. Onions contain quercetin which is a powerful antioxidant and anti-inflammatory and helps prevent infections and improves the immune system. Allicin is a good antibacterial, anti viral, anti fungal and there is some evidence it may prevent certain types of cancer related the stomach.

Green Smoothies Are A Great Way To Easily Get Lots Of Good Nutrition 

For people who don’t have much time to be preparing and eating all of these foods, you can easily pack a lot of good foods into a delicious green smoothie. Green smoothies retain the fibre, and blending the fruits and vegetables can enhance bioavailability of certain nutrients.

When first experimenting with green smoothies, it’s best to start off simple and then add more things later.

I would usually suggest to start of with around 60-70% fruits and 30-40% leafy greens vegetables like baby spinach. After you get used to it, you can then lower the amount of fruit and have a more even ratio.

If you’re concerned about the rise of blood sugar when you consume green smoothies, then make sure you add blueberries! Berries can blunt the risk of rapid increase in blood sugar when drinking smoothies.
