    cancer risk reduction

    While a healthy, vegetable-rich diet lowers cancer risk in general, studies have revealed that certain types of vegetables have more anti-cancer properties.

    Glucosinolates, sulfur-containing compounds, are found in cruciferous vegetables. The bitter taste of the plants and their cancer-fighting abilities may be due to the presence of Glucosinolates. The body breaks down glucosinolates into various valuable chemicals, including sulforaphane.

    Sulforaphane has been discovered to block the enzyme histone deacetylase (HDAC), which is vital in cancer cell development. Because of its ability to inhibit HDAC enzymes, foods like arugula microgreens containing sulforaphane could become an important aspect of cancer treatment.

    According to some research, eating a diet rich in cruciferous vegetables can lower the risk of breast cancer, colorectal cancer, lung cancer, prostate cancer, and other cancers. However, the research is limited, and additional high-quality information is needed before scientists can confirm these benefits.

    Osteoporosis prevention

    Arugula microgreen is high in calcium and vitamin K, both of which are necessary for bone health. Vitamin K is important in bone metabolism. Vitamin K deficiency can increase the risk of bone fracture. One of the key dietary sources of vitamin K is leafy green vegetables.

    Vitamin K supports bone health by playing an important part in bone mineralization and aiding in the absorption and excretion of calcium, another important nutrient for bone health. Arugula also provides 32 milligrams (mg) of calcium per cup, which helps meet a person’s daily calcium requirements.

    Several review studies have revealed that consuming veggies and microgreens lowers the risk of type 2 diabetes. Leafy green veggies are especially advantageous, according to a 2016 review study.

    Arugula microgreens and other cruciferous microgreens are high in fiber, which aids in blood glucose regulation and may improve insulin resistance. High-fiber foods keep individuals satiated for longer, which can help them avoid overeating.

    Heart health

    Consumption of cruciferous microgreens offers heart-protective properties. Diets high in cruciferous vegetables, salads, and green leafy vegetables have been linked to a lower risk of cardiovascular disease, according to a 2017 meta-analysis.

    Furthermore, a 2018 study published in the Journal of the American Heart Association revealed that eating a diet rich in cruciferous vegetables can help older women avoid atherosclerosis. Atherosclerosis is a disorder in which plaque builds up in the arteries, raising the risk of cardiovascular disease.

    The high concentration of beneficial plant components such as polyphenols and organosulfur compounds in these Arugula microgreens may explain their heart-protective properties.

    Usually a micro crop, Arugula can be harvested in 7 to 10 days. This plant needs two weeks to achieve the petite size and three to four weeks to reach baby leaf size.
