How Spinach Prevents Chronic Disease

Spinach, like many vegetables, prevents several chronic diseases that plague America today. Most notably, spinach helps to prevent cancer, diabetes, and cardiovascular disease.

    • Quercetin also provides additional apoptotic activity in tumor cells, meaning it can cause tumor cells to die. (7)

    • Quercetin has been shown to prevent lung and colorectal cancers in many different studies. More studies must be done to confirm quercetin’s effects on ovarian cancer. (8)

  • Spinach is also rich in an antioxidant called kaempferol. Kaempferol has been shown to reduce risk of several cancers, including skin, liver, and colon cancers. It primarily focuses on increasing apoptotic activity within tumor cells. (9)
  • Moreover, spinach is rich in two compounds, MGDG and SQDG, which have been shown to decrease the size of cervical cancer tumors. (10)

    • One study showed that spinach reduced systolic and diastolic blood pressure levels by up to 5 mmHg. (16) Regularly consuming spinach can keep nitrate levels high. Spinach is broken down slowly and keeps high levels of circulating nitrates.

  • Also, spinach is rich in Vitamin K1. This is an essential vitamin for preventing blood clots. Blood clotting is often the result of high LDL cholesterol and LDL cholesterol plaque buildup. Spinach is one of the richest sources of vitamin K, certainly compared to other fruits and vegetables. So, be sure to incorporate spinach into your diet! (17)
