Spinach has an extremely high nutritional value and is rich in antioxidants. It is a good source of vitamins A, B2, C and K, and also contains magnesium, manganese, folate, iron, calcium and potassium.
Other pros are:
- The flavonoids and antioxidants found in spinach, particularly the antioxidant beta-carotene, have been shown in multiple studies to help combat many cancers, including breast, prostate and ovarian cancer. Spinach also boosts eye health and has strong anti-ageing properties.
- A recent study found a bowl of spinach every day increases muscle efficiency. Researchers from the Karolinska Institute in Sweden found participants who consumed 300 grams of spinach a day reduced the amount of oxygen required to power their muscles while exercising by five per cent. The effect was noticable after just three days of spinach consumption.
A seed is an embryonic plant enclosed in a protective outer covering. The formation of the seed is part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants.
Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.
Seeds have been an important development in the reproduction and success of gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates.
