What are superfoods?

27 Sep 2021 • 12 min read


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. 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.

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

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
