Many people know spinach primarily as a warm, creamy vegetable, but it is also delicious raw in a salad. Here you can find out when you can eat spinach raw and when you should be careful.
In addition to many healthy nutrients, spinach also contains oxalic acid. This binds calcium, iron and magnesium. Your body can therefore absorb less of the substances you eat if you have consumed oxalic acid. If you suffer from a deficiency of the substances mentioned or suffer from kidney stones, you should be careful with raw spinach.
Eat spinach raw to avoid oxalic acid
In particular, long-ripened, strong spinach leaves with a wavy structure contain a lot of oxalic acid. When cooking, some of the acid is released into the cooking water. If you drain the cooking water, the amount of acid will be reduced. However, nutrients also dissolve in the water, which are then also lost.
Young spinach leaves contain less oxalic acid. You can use them raw in salads or in smoothies. So no nutrients are lost. In addition, the consistency of the delicate, smooth leaves is more pleasant than that of the somewhat coarser, long-ripened leaves.
Nitrate in raw spinach
Spinach can be high in nitrates, especially during the darker months. This substance reacts in the body to form nitrite. Nitrite can turn into carcinogenic nitrosamines. In addition, nitrite inhibits oxygen uptake. The intake of nitrite can therefore be life-threatening, especially for children.
Nitrate is primarily contained in the stems and larger leaf veins as well as the outer leaves. When you remove these plant parts, you remove some of the nitrates. You should also eat spinach when it is still very fresh. This not only tastes better, but also ensures that microorganisms have less time to form nitrite.
Be sure to buy organic spinach, as organic farming doesn’t use nitrate fertilizer. Therefore, organic spinach usually contains less nitrate.
Healthy combinations with spinach
Since oxalic acid binds calcium, among other things, it is worth combining spinach with foods containing calcium. How about a delicious yoghurt dressing for the spinach salad? This not only tastes good, but also ensures that you don’t lose too much calcium.
To mitigate the risks of nitrate, for example, add lemon juice to the dressing and drink freshly squeezed orange juice. This is how you absorb vitamin C, which limits the formation of nitrosamines.
