What side effects this plant can have?
This plant can cause various adverse health effects including increased urinary oxalate excretion, oxidative stress, DNA damage, eye inflammation, and insomnia. The high concentration of oxalates in spinach can lead to higher levels of oxalate in the urine, which significantly increases the risk of developing kidney stones. Excessive consumption may also trigger oxidative stress and subsequent DNA damage within cellular structures. Furthermore, certain compounds in the plant have been linked to eye inflammation and disrupted sleep patterns resulting in insomnia. These physiological complications highlight the importance of moderation when consuming this leafy green.
According to a study published by "The Journal of urology", gastric administration of 5 mmol. oxalate loads including spinach can lead to significant oxalate absorption. In 6 adult patients, increasing the gastric loading time resulted in a linear increase in urinary oxalate excretion. Specifically, 15 to 21% of the gastric oxalate load appeared in the urine after 2 hours of loading. This amount increased to 24 to 45% after 4 hours of loading. Ultimately, as much as 62% of the load was excreted after 6 hours of loading.
The main side effects this plant can have are shown in the list below.
- increased urinary oxalate excretion
- oxidative stress
- DNA damage
- eye inflammation
- insomnia
What herbs are paired with Spinacia oleracea?
This plant, Spinacia oleracea, pairs optimally with aromatic herbs such as nutmeg, garlic, basil, and mint to enhance its mild, earthy flavor profile.
