Lamb’s lettuce and its health benefits

Lamb’s lettuce is not only a treat for the taste buds, but also a real nutritional powerhouse. It contains the highest iron content of all lettuce varieties – an essential mineral that transports oxygen around the body. With 2 mg of iron per 100 g, it makes a significant contribution to this. The body can absorb iron particularly well in combination with vitamin C. And lamb’s lettuce is particularly rich in this vitamin: its content (35 mg/100 g) is three times higher than that of lettuce, which strengthens the immune system and supports the development of bones and connective tissue.

In addition to these vitamins, lamb’s lettuce provides valuable minerals such as potassium (421 mg/100 g), magnesium (13 mg/100 g) and calcium (35 mg/100 g). Magnesium plays a central role in muscles, nerves and the immune system. With only 18 kcal, 0.8 g carbohydrates, 1.8 g protein and 0.4 g fat per 100 g, lamb’s lettuce is also an ideal choice for a healthy and calorie-conscious diet. Its fibre promotes good digestion.

However, there are also some aspects to consider. Like other leafy vegetables, lamb’s lettuce storesnitrates from the soil, which under certain conditions can be converted into nitrosamines, which are considered potentially harmful to health. Nevertheless, the Federal Institute for Risk Assessment does not advise adults against eating vegetables containing nitrates – on the contrary, a varied diet with plenty of fresh vegetables is expressly recommended. If you want to be on the safe side, choose organic lamb’s lettuce grown outdoors, as this usually has a lower nitrate content.

Eating healthily with lamb’s lettuce – storage and preparation

Lamb’s lettuce is one of the more delicate types of lettuce and should be eaten as fresh as possible. Lamb’s lettuce only keeps for three days in the normal fridge compartment. With the EasyFresh safe, you can extend the shelf life to seven days by regulating the air supply. In the BioFresh safe at just above 0°C, your lamb’s lettuce will stay fresh for up to 19 days. If your salad does start to go a little soft, you can refresh it with a quick ice bath to make it crisp again.

As sand and soil often accumulate between the delicate leaf rosettes, thorough cleaning is essential. The best way is to swirl the salad several times in cold water instead of rinsing it under running water, as the delicate leaves can easily be damaged. Then dry it in a salad spinner or leave the leaves to drain on a kitchen towel.

Lamb’s lettuce is traditionally eaten raw, but is also suitable as an ingredient in creative dishes. Its nutty aroma harmonises particularly well with strong and spicy ingredients such as bacon, goat’s cheese, roasted nuts or savoury dressings. Combinations with fruity components such as apple, pear or pomegranate are also very popular. In addition to being prepared in the traditional way as a salad, lamb’s lettuce can be used as a substitute for spinach in warm dishes. This green leafy vegetable can even be used as a base for aromatic pesto or in smoothies.

When eaten raw, its heat-sensitive nutrients, such as vitamin C, are optimally preserved.

To prevent the tender leaves from wilting before eating, add the dressing just before serving.

Pregnancy and lamb’s lettuce – vitamin C and folic acid

Lamb’s lettuce is a particularly valuable source of nutrients during pregnancy, as it is rich in essential vitamins and minerals. Its high content of folic acid, a B vitamin that plays a central role in cell division and the development of the baby’s nervous system, is particularly noteworthy.

With 145 µg of folic acid per 100 g, lamb’s lettuce makes a significant contribution to meeting the increased requirements of expectant mothers. During pregnancy, the recommended daily intake increases to 550 µg, which is why it is advisable to regularly include foods containing folic acid in your diet.

In addition, lamb’s lettuce contains large amounts of beta-carotene, which is converted into vitamin A in the body and is important for the healthy development of an unborn child’s eyesight.

Breastfeeding women also benefit from the nutrient richness of this lettuce, as their vitamin A requirement is even higher at 1500 µg per day. In addition, breastfeeding women need 450 µg of folic acid daily to meet the increased demand for milk production. Regular consumption of lamb’s lettuce can therefore help to provide the body with essential vitamins after childbirth.

However, expectant mothers should take particular care to wash lamb’s lettuce thoroughly to remove any traces of germs or pesticides.
