Oxalic acid is a common organic acid that is found in many plants, such as spinach, beans, tea, etc. However, there are some misunderstandings about oxalic acid, so let's clarify them.
Myth 1: Only spinach contains oxalic acid.
In fact, many plants contain oxalic acid, and spinach is just one of them. Other vegetables such as legumes, tea, etc. also contain a certain amount of oxalic acid. Therefore, it is not correct to think that only spinach contains oxalic acid.
Myth 2: Oxalic acid can cause kidney stones.
Although oxalic acid can combine with calcium in the kidneys to form calcium oxalate stones, oxalic acid itself does not directly cause kidney stones. The formation of kidney stones is also related to a variety of factors such as individual differences, dietary habits, and lifestyle habits.
Myth 3: Oxalic acid can damage your health.
In fact, oxalic acid has an antioxidant effect under certain conditions, which is beneficial to human health. At the same time, oxalic acid can also be metabolized in the human body without causing damage to the body.
Myth 4: Oxalic acid can cause indigestion.
Oxalic acid, in response to gastric acid, can combine with proteins in food to form precipitates, which may affect the absorption function of the digestive tract. However, moderate oxalic acid intake does not have a significant negative effect on the digestive system.
Myth 5: Oxalic acid affects calcium absorption.
Although oxalic acid can combine with calcium to form insoluble calcium oxalate, which affects calcium absorption. However, moderate oxalic acid intake does not have a significant effect on calcium absorption. At the same time, the body's absorption of calcium is also affected by a variety of other factors.
Myth 6: Oxalic acid in spinach cannot be removed.
In fact, some of the oxalic acid in spinach can be removed by blanching, cooking, etc. In addition, the oxalic acid content in spinach is also affected by factors such as planting environment and variety. Therefore, proper treatment methods can effectively reduce the oxalic acid content in spinach.
Myth 7: Oxalic acid is harmful.
Although excessive intake of oxalic acid may cause certain negative effects on the body, moderate oxalic acid intake is also beneficial. Oxalic acid has an antioxidant effect that can help remove free radicals in the body and help prevent certain diseases. Therefore, oxalic acid intake should be moderately controlled, rather than completely avoided.
Myth 8: The oxalic acid in spinach does not have any benefits.
Although spinach is high in oxalic acid, spinach is also rich in nutrients, such as vitamin C, vitamin K, folic acid, etc. Therefore, eating spinach in moderation is still good for health. At the same time, some of the oxalic acid in spinach can be removed through appropriate treatment methods to reduce the negative effects.
In summary, oxalic acid intake should be controlled in moderation rather than avoided entirely. At the same time, appropriate treatment methods should be taken for vegetables containing oxalic acid to reduce their content. In addition, the above misunderstandings should also be avoided in the cognition of oxalic acid, so as not to cause unnecessary panic and misunderstanding.
