What makes Brussels sprouts so healthy is not only plenty of vitamin C. When bought regionally, the winter vegetable is also a sustainable food.
Brussels sprouts belong to the cruciferous family and have been cultivated in Europe for around 200 years. At that time, farmers in Belgium began to grow the cabbage variety – which is why the florets are also called “Brussels cabbage”.
Brussels sprouts are a particularly digestible variety of cabbage that usually does not cause bloating or abdominal pain. Its strong aromatic flavor becomes milder after the first frost: then the sugar content increases and the cabbage tastes sweeter and less bitter. But whether strong or mild – Brussels sprouts are always healthy.
Brussels sprouts: Healthy thanks to vitamins and minerals

Numerous important vitamins and minerals make Brussels sprouts healthy (data from the USDA per 100g):
Vitamin C (85 mg) strengthens the body’s defences. 100 grams of Brussels sprouts contain about 85 milligrams of vitamin C.
Vitamin B-6 (0.2 mg) strengthens the immune system, among other things.
Vitamin A (38 micrograms) primarily supports bone formation, the skin and visual performance.
Vitamin K (177 micrograms) regulates cell growth and is important for blood clotting. Attention: Vitamin K inhibits the effect of vitamin K antagonists, which are contained in some medicines. If you are taking such medications, you should not consume too much vitamin K.
Potassium (389 mg) controls the transmission of stimuli in our muscles.
Calcium (42 mg) strengthens our bones and teeth.
Iron (1.4 mg) primarily transports oxygen in the blood.
According to research by the NDR, the vitamin C content in frozen Brussels sprouts is higher than in fresh ones. It depends on what “fresh” means. If you harvest Brussels sprouts in your garden and process them directly, the vitamin C content will be higher than fresh Brussels sprouts that have been stored in the cold store for some time and have been transported.
Brussels sprouts as part of a healthy diet
Not only the high amount of vitamins and minerals make Brussels sprouts healthy. It also contains other substances that promote our health:
Bitter substances stimulate digestion and soothe the gastric mucosa. They can even relieve mild abdominal pain.
Together with iron and vitamin B, folic acid (folate) promotes healthy blood formation.
Studies indicate that Brussels sprouts may help reduce the risk of type 2 diabetes.
With just under four grams of protein and fiber per 100 grams, Brussels sprouts not only provide important energy, but also fill you up in the long term and get your digestion going.
So it pays to include Brussels sprouts in your diet. Especially in winter it is an important supplier of health-promoting substances: it is one of the few regional vegetables that are still growing.
