Khaberni - Spinach is one of the most nutrient-rich vegetables, as it contains iron, antioxidants, and vitamins; however, the preparation method plays a crucial role in determining what the body retains from these nutrients. According to a health report, some cooking methods help preserve nutritional value better than others.
Steaming is considered one of the best methods, as it allows for the preservation of a higher percentage of vitamin C and the vitamin B group, alongside beta-carotene. This is because the spinach is not submerged in water, reducing the loss of water-soluble nutrients.
Results have shown that vegetables cooked by steaming retain higher levels of antioxidants compared to boiling, although there is limited loss of some vitamins.
Quick cooking with a small amount of fat, such as olive oil, not only preserves nutrients but may also enhance their absorption. Some compounds, like carotenoids, need fat to be efficiently absorbed into the body.
Furthermore, cooking at relatively low temperatures helps preserve beneficial compounds such as lutein, which is linked to eye health.
Although blanching may lead to some nutrients being lost in the water, the "quick blanching" method followed by cooling helps reduce levels of oxalates, compounds that can inhibit calcium absorption and are associated with the formation of kidney stones in some people.
Estimates suggest that this process can reduce oxalates by up to 80%, making it a suitable option in some cases, especially for those with kidney-related issues.
Raw spinach retains higher levels of folate and vitamin C, both heat-sensitive nutrients. Adding it to salads or smoothies also makes it easy to incorporate into a daily diet.
However, cooked spinach is more nutrient-dense per serving, which means obtaining the same amount of nutrients requires consuming a larger quantity of raw spinach.
In the end, there is no single ideal method. Alternating between steaming, light frying, and raw consumption may be the best approach to benefit from the full nutritional value of these vegetables.
