Can water cook noodles after cooking spinach

The water used to cook spinach can be used to cook noodles, but it should be noted that spinach water may contain substances such as oxalic acid. The residual oxalic acid after blanching spinach may affect the taste of noodles, and long-term excessive intake of oxalic acid may increase the risk of kidney stones. If you want to use spinach water, it is recommended to blanch spinach thoroughly first to reduce oxalic acid content, or pair it with high calcium ingredients to neutralize oxalic acid. During the blanching process of spinach, oxalic acid partially dissolves in the water. This substance is relatively stable at high temperatures and may adhere to the surface of the noodles during the cooking process. The combination of oxalic acid and calcium may form precipitates that are not easily absorbed, affecting the efficiency of mineral absorption. Occasional consumption does not pose significant harm to healthy individuals, but individuals with gastrointestinal sensitivity may experience discomfort such as bloating. Extending the boiling time during blanching can help decompose some oxalic acid, while discarding the first blanching can reduce the risk. People with kidney stones or hyperoxaluria should avoid using spinach water in special circumstances. This group of people has weaker ability to metabolize oxalic acid, and excessive intake may worsen the condition. Children and the elderly also need to choose carefully due to their weaker digestive function. If the noodles need to retain the broth, it is recommended to boil them with fresh water to ensure safety and maintain the original flavor of the noodles. In daily diet, attention should be paid to the scientific combination of ingredients. Spinach itself is rich in iron and vitamin K, and proper cooking can maximize the retention of nutrients. When cooking noodles, it can be paired with high-quality protein foods such as tofu and eggs, which can enhance nutritional value and balance the effects of oxalic acid. For individuals with special physical conditions, it is recommended to consult a nutritionist to develop a personalized dietary plan that ensures both dietary safety and balanced nutrition.
