Artichokes: their health benefits, how to cook them and how to get the most out of them
This vegetable from the thistle family appeals to both young and old alike with its delicate, sweet flavour … but how can you get the most out of its properties?
The artichoke: its ‘leaves’ and ‘heart’
The artichoke, or Cynara scolymus to give it its scientific name, is a variety of the thistle species, closely related to milk-thistle.
When you eat an artichoke, you’re actually eating:
- the base of its bracts (scale-like outer leaves);
- and the receptacle of its immature flower head, a gourmet delicacy known as the ‘artichoke heart ’.
If artichokes are allowed to carry on growing, the bracts end up spreading out and they come into flower (the ‘choke’ which grows on top of the heart gets bigger and turns purple), at which point they are no longer edible.
How should you cook an artichoke in order to preserve all its health benefits?
Artichokes are normally consumed cooked, particularly the famous ‘Camus’ variety from Brittany, though some can also be eaten raw, like the ‘violet de Provence’.
The best way to prepare artichokes to preserve their benefits is to steam them or cook them in a pressure cooker.
For this, it’s usually best to remove the excess stem of the artichoke by hand in order to get rid of most of the tough fibres that are buried in the heart. You then have various options:
- you can cook the artichoke whole : guests can then enjoy their own artichoke, savouring the base of the leaves before eating the much-prized heart;
- or you can trim the artichoke before cooking. For this, you need to use a very sharp knife to cut away everything but the heart. To prevent the delicate artichoke from becoming oxidised during preparation, make sure you rub it with lemon juice as you go.
Both these methods preserve artichokes’ nutritional qualities. They can either then be served with a vinaigrette, or for the ‘gourmands’ among you, a béchamel or mustard sauce.
Other recipes (such as violets de Provence braised in white wine, or sautéd with white wine and olives) where the artichokes are cooked in a frying pan on a high heat, may result in some of their precious nutrients being lost.
Artichokes: an excellent slimming aid
Very low in calories but high in fibre and packed with antioxidants(1), the artichoke provides many nutritional benefits, making this key vegetable of the Mediterranean diet a major aid to slimming. 100 grams of cooked artichoke has the following nutritional value:
- 33.2 kcal;
- less than 1g of fat and carbohydrates;
- 427mg of potassium ;
- 0.29mg of zinc;
- 89mcg of B9 vitamins;
- and 9mcg of vitamin C (2).
A number of studies have shown that artichokes help to promote weight loss and reduce blood lipid levels (3-5).
A detox-supporting plant
However, it is primarily for its benefits as a detox aid that the artichoke is consumed by devotees of healthy eating. Indeed, artichokes help to:
- support detoxification ;
- ensure a good flow of digestive juices;
- maintain a healthy liver;
- and support digestive comfort(6).
This is because of their high content of cynarin, also known as dicaffeoylquinic acid , a specific polyphenol considered by scientists to be their active ingredient (7).
To significantly increase your cynarin intake, you could take a cynarin-rich artichoke extract , such as that included in the supplement Liver Support Formula (category Liver and detoxification).
And if you’re keen to boost your intake of beneficial fibre, you could combine the above with Psyllium Seed Husk, a blond psyllium supplement.
It’s worth noting too that artichokes also contain the excellent flavonoid luteolin, a substantial amount of which is offered by the supplement Luteolin.

I am merely judging the delivery system
I am merely judging the delivery system, which was flawless. It wouldn't make any sense to comment on the efficacy of the supplements, since that is only possible on a statistical basis. Even if something doesn't improve, that doesn't have to mean that the supplement doesn't work, since one doesn't know how it might have worsened without the supplement and the opposite might also apply, since many symptoms are psychosomatic and the supplement might provide a placebo effect.
