From the earthy stems to the crunchy florets, from Tenderstem to purple-sprouting varieties, broccoli is filled with nutritional vitamins, antioxidants and polyphenols that not solely construct up our coronary heart and brain health but additionally could halt cancerous cells from taking maintain.
Many of those attributes are a results of broccoli being a cruciferous vegetable, explains nutritionist Dominique Ludwig. “Which means that it comprises pure sulphur-containing bioactive plant compounds often known as glucosinolates. This not solely provides them a singular pungent aroma and barely bitter flavour, but additionally has advantages for us after we eat them.”
Listed here are a few of the methods broccoli can bolster your well being – and a few scrumptious recipes that may have you ever munching by a number of servings per week.
The well being advantages of broccoli
1. Enhances coronary heart well being
Repeatedly, research have discovered that broccoli is great for our hearts.
One current paper discovered that contributors who ate a soup made with broccoli and different cruciferous greens for lunch for a fortnight noticed their blood strain drop, in flip reducing their danger of a coronary heart assault or stroke by 5 per cent.
An earlier study from Imperial School London discovered the sulforaphane in broccoli, which supplies it its robust scent and bitter flavour, activated a protecting protein within the arteries, decreasing irritation and reducing the chance of atherosclerosis (a build-up of fatty plaques within the arteries).
Broccoli additionally comprises potassium, a mineral that may help cardiovascular well being and may be useful in managing blood strain, and vitamin Ok, which regulates blood clotting and circulation, Ludwig notes.
2. Protects towards prostate and colon most cancers
Some studies have discovered that males who ate a broccoli-rich eating regimen (400g per week) had a decrease danger of growing prostate most cancers.
It’s thought that this impact is right down to isothiocyanates (compounds created by the physique because it breaks down broccoli).

A separate paper from Imperial School London discovered that for each further 260 micrograms of folate in an individual’s eating regimen per day – which is in broccoli and leafy greens – the chance of colon most cancers fell by 7 per cent.
Further research has discovered that mice fed a eating regimen wealthy in indole-3-carbinol (which is produced when the physique breaks down the glucosinolates in broccoli) had been protected against intestine irritation and colon most cancers. The scientists behind that examine, from the Francis Crick Institute, concluded that, whereas we are able to’t shield towards genetic components that improve our danger of most cancers, “we are able to in all probability mitigate these dangers by adopting a eating regimen with loads of greens”.
3. Boosts mind energy
Broccoli’s excessive folate content material is believed to help the well being of our mind. “Folate helps to decrease ranges of homocysteine (an amino acid) in our blood which is useful for our cardiovascular well being and subsequently our long-term mind well being,” Ludwig explains.
The hit of iron that broccoli gives may additionally play a component in defending our cognition (it comprises 0.7mg per 100g). “Iron is critical for our mind chemistry and neurotransmitter formation,” she says.
Whereas there’s numerous evidence {that a} eating regimen wealthy in plant compounds referred to as flavanols protects the mind, consuming one explicit flavanol present in broccoli referred to as kaempferol has been linked to a 51 per cent decrease risk of dementia.
3. Reduces arthritis danger
The sulforaphane in broccoli is believed to sluggish the development of arthritis and perhaps even forestall it. Lab research involving mice present that the compound blocks the inflammatory course of in joints that fuels situations and would possibly sluggish cartilage harm in osteoarthritis.
A separate study in individuals who adopted a eating regimen excessive in broccoli – the equal of three parts per day in the form of a soup – skilled decrease ranges of ache brought on by arthritis.
4. Protects eye well being
Broccoli additionally works to guard our sight. “Broccoli comprises carotenoids, antioxidants that shield the attention from oxidative harm,” Ludwig notes.
This antioxidant can also be thought to scale back the chance of growing cataracts, and sluggish the development of the situation if it does happen, she says. Moreover, the physique converts carotenoids into vitamin A, which is required to supply pigments which are wanted to see.
5. Bolsters intestine well being
Greens are one of many richest sources of fibre, which is crucial for a wholesome intestine.
Broccoli is a powerhouse on this regard because it comprises each soluble and insoluble fibre. Soluble fibre absorbs water from the big bowel, making stools softer, whereas insoluble fibre stimulates the intestine to launch water and mucus to assist stool transfer by the intestine.
Per 80g portion, it comprises 2g of the 30g of fibre that we needs to be consuming every day.
What’s extra, several types of broccoli – whether or not commonplace, Tenderstem or purple sprouting varieties – every rely as completely different vegetation, Ludwig notes.

Purple sprouting broccoli
Normal broccoli – with a thick stem and many florets, technically referred to as calabrese – and Tenderstem, which is also referred to as broccolini and is a hybrid of broccoli and Chinese language kale, are the 2 most typical varieties of broccoli offered within the UK.
Broccoli and Tenderstem are nice for our well being, although purple broccoli and broccoli sprouts are even higher – Christopher Pledger
“Each have an analogous diet profile,” Ludwig notes, although some analysis means that Tenderstem has barely extra folate (a vitamin that retains crimson blood cells and the nervous system wholesome) and carotenoids (an antioxidant that protects cells from harm).
The much less in style purple sprouting broccoli could also be even higher for our well being. “It comprises the extra advantages of the purple plant compounds referred to as anthocyanins,” Ludwig explains. Basically, it lends an even bigger antioxidant punch per chew.
However broccoli sprouts (broccoli vegetation which are three to 5 days previous and resemble cress) could prime the checklist relating to well being. “They’ve the very best quantity of sulforaphane (a robust antioxidant) than another kind of broccoli,” she says.
The healthiest methods to eat broccoli
Earlier than you even get to consuming broccoli, there are methods of upping its well being advantages.
“Once we chop broccoli we encourage the event of sulforaphane,” explains Ludwig. So reducing the vegetable and leaving it for a short time is useful.
“This will not be very sensible in on a regular basis cooking, however may be nice if chopped right into a salad, for instance,” she says. Consuming broccoli uncooked as a part of a salad, or crudités, additionally preserves extra vitamin A, in addition to folate.
On the subject of cooking broccoli, the aim is to protect the water-soluble nutritional vitamins (those who dissolve in water) and plant compounds (like polyphenols) as a lot as potential.
Steam, fry or boil: which method is finest?
Steaming or stir frying are the very best methods to do that, versus boiling. These cooking strategies will even make it simpler for the physique to soak up the carotenoids inside broccoli, Ludwig says.
“Cooking in an excessive amount of water or for too lengthy can result in the best reductions in vitamin C [an 80g serving contains 63mg, over two thirds of our daily recommended amount] glucosinolates and folate,” she notes.
Frozen broccoli shouldn’t be disregarded, nevertheless. “Since broccoli loses its vitamins over time, freezing can act like a time capsule, trapping the vitamins in place and preserving them for longer,” Ludwig notes. “Whereas losses can nonetheless happen, the broccoli is normally frozen at peak ripeness when vitamins are at their highest.”
“The secret’s to not overcook your broccoli and to take pleasure in it al dente wherever potential,” she provides. “Broccoli not solely loses vitamins as we cook dinner it, but additionally it may turn out to be unappealing and soggy.”
Verdict: Is broccoli wholesome?
“I strive to not put anyone meals on a pedestal over others as the important thing to a nutritious diet is variety,” Ludwig says. “However broccoli is flexible, cheap and extensively obtainable and positively has an necessary place in a nutritious diet.”
Whereas leafier inexperienced greens equivalent to spinach, kale or chard technically beat broccoli when it comes to nutrient density per chew, the particular plant compounds all broccoli varieties include implies that the vegetable is great for our well being.
