What are superfoods?

chopping board full of superfoods
Want to know what superfoods are and what the big fuss is about? Learn all about superfoods and discover 23 of the best superfoods you can include in your diet here.

Still a bit puzzled about ‘superfoods’? We’ve got you covered. Find out what they are, why they’re beneficial for your health plus 26 of the best, below.

What are superfoods?

The word usually describes a food, or indeed drink, that’s highly nutritious – from kale, beetroot and berries to nuts, green tea and salmon – although there’s no set legal definition.1

And when we say highly nutritious, we mean it’s a good source of things like protein, fibre, iron, copper, magnesium, antioxidants – all the good stuff! As well as this, they also contain natural plant molecules which have antioxidant properties.

4 top benefits of superfoods

Read on to find out the top 4 benefits of superfoods...

  1. Superfoods are full of vitamins and minerals

Superfoods contain lots of vitamins and minerals. Plant foods are notoriously rich in vitamins and minerals like vitamin C, B vitamins, magnesium, iron and more.

Your body needs a certain amount of these micronutrients to maintain a varied and balanced diet optimum health.2

  1. Superfoods contain antioxidants

Superfoods contain natural plant molecules which have powerful antioxidant or anti-inflammatory properties.

Antioxidants have been shown to reduce the damaging effects of free radicals, scavenging atoms that have been linked to the development of heart disease, arthritis and Alzheimer’s among others.3

  1. Superfoods can promote good health

Often a superfood can promote health beyond simple nutrition.

For example, some superfoods, like oats, are wholegrains and have been shown to help reduce cholesterol and regulate blood sugar.4

  1. Superfoods for weight control 

As superfoods are mainly plant-based or considered natural, including more into your diet could help you lose weight and/or maintain a healthy weight.

Why are superfoods also controversial?

Many experts say that with no legal definition of the word, the term is arbitrary and may mislead people into believing that a few foods will counteract an otherwise bad diet.

Some scientists are also concerned that the nutritional benefits may be over-sold: it can be tricky to prove scientifically how one single food impacts your health.5

26 of the best superfoods

There may be no such thing as a miracle food, but these plant foods can still make a valuable contribution to a healthy, balanced diet:

  1. Pomegranate

This fruit contains a host of nutrients, including fibrevitamin Avitamin C and some B vitamins, plus calcium, potassium – needed for the nervous system and muscle health – and iron, for red blood cells.6,7

It also contains 3 times as many antioxidants as green tea.8

A 2012 randomised placebo-controlled study by Sheffield Hallam University showed that drinking 330ml of pomegranate juice every day could lower blood pressure in healthy, middle-aged people.9

  1. Turmeric

This spice is a source of bioactive plant compounds called curcuminoids, shown to have strong anti-inflammatory and antioxidant properties.

A 2017 review by USA’s Central Michigan University found it can reduce blood pressure and lower cholesterol levels, and also has an anti-anxiety effect.11

  1. Spirulina

This famously bright blue-green algae species is an ancient plant that has inhabited the world for over 2.4 billion years.

Spirulina is considered a superfood due to its nutrient content, which includes vitamin B12, vitamin A, vitamin B1, vitamin B2, iodine, and iron.

These nutrients can help support heart health, immune function, and spirulina’s antioxidant content can help protect against oxidative stress.

Spirulina is also a great source of protein, calciumpotassium, and phosphorus needed for good bone health the maintenance of normal bones; and also iron and magnesium essential for energy release and electrolyte balance.13,14

A 2014 study in Journal of the Science of Food and Agriculture found that taking 1g of spirulina per day for three months lowered overall cholesterol by almost 9% in people with raised levels of blood fats.15

It is one of the most nutrient-dense foods on the planet and grows in freshwater ponds under warm sunlight.

  1. Quinoa

This wholegrain isn’t just a great source of fibre.

It’s also higher in protein than most grains – it contains a good balance of essential amino acids – plus magnesium, B-vitamins, iron, potassium, calcium, phosphorus, copper, manganese, zinc and vitamin E, both of which help protect cells from oxidative stress.17,18

It also contains antioxidants, including quercetin, which have been shown to have anti-inflammatory and anti-microbial effects.19

A 2004 study on people who ate quinoa instead of gluten-free breads and pastas experienced a drop in blood sugar, insulin and blood fat levels – factors important for heart health.20

  1. Kale

Dark green, leafy vegetables are all superfoods, but many think kale wins the prize for its very high levels of vitamin C, vitamin A and vitamin K – needed for normal bone function and blood clotting.

It also contains vitamin B6, which is important for the normal functioning of both the nervous system and the immune system health.

Plus minerals iron, manganese, calcium, copper, potassium and magnesium.22,23

It’s also high in lutein and zeaxanthin, two nutrients important for eye health.

A French 2006 population study showed that people with low levels of these nutrients in their eyes were at increased risk of sight-threatening diseases such as age-related macular degeneration and cataracts.24

As well as kale, other green leafy vegetables are often considered to have superfood status. Some of the most popular edible green leafy vegetables include:

  • Spinach
  • Collard greens
  • Swiss chard
  • Spring greens

They contain a variety of important micronutrients like calcium, folate, magnesium, iron, vitamin K and vitamin C, as well as a healthy serving of fibre.26 

The antioxidants found in these foods have been shown to help:

  • Prevent certain birth defects
  • Protect bones from osteoporosis
  • Prevent against inflammatory diseases27

Not everyone is going to love munching on some raw kale or other plain green leafy vegetables; try including them in stir-frys, curries, soups, salads, smoothies, pasta dishes and more.

  1. Kefir

Kefir is a drink made from fermented milk that is rich in protein, B vitamins, calcium, potassium and probiotics.

It is quite similar to yoghurt, but typically contains more healthy probiotics and has a thinner consistency, which is why it is consumed as a drink.

The probiotic strains in kefir are largely responsible for its superfood status, and have been found to help reduce cholesterol, lower blood pressure and improve digestion.40,41,42

You can find it in health food shops or make it by yourself if you’re feeling particularly adventurous – or want to avoid added sugar.

The Mediterranean diet is hailed as one of the healthiest ways to eat. One of the key components is olive oil – a natural oil extracted from the fruit of olive trees. It contains a lot of monounsaturated fats (MUFAs) and polyphenolic compounds.

Consuming extra virgin olive oil in your diet provides you with healthy fats, as well as polyphenols.

However, refined (processed) olive oils won’t benefit you in the same way so make sure to buy some of the good stuff!45

Are superfoods suitable for everyone?

It depends on the superfood in question and the person consuming it!

As with any food or supplement, you should always add it to your diet slowly to see how or if your body reacts to it.

Always check the labels of processed products like superfood powders and check with your doctor that you can take them if you are on medication.

However, as superfoods tend to be plant-based or largely natural, they should be safe for most people without allergies or other health issues.

The final say

  • Superfoods are foods or drinks that are considered highly nutritious and good for health – although there is no set legal definition
  • They tend to contain lots of vitamins, minerals, antioxidants, fibre and healthy fats
  • You can enjoy an array of different superfoods, from plant-based ones like vegetables and herbs and spices to seafood and some dairy products
  • Superfood powders can be useful for throwing into a blender with fruits and vegetables and increasing your nutrient intake
  • Try and include more into your diet and see if they make a difference in your health and life!
