Spinach Nutrition Facts
The various health benefits of spinach are due to the presence of minerals, vitamins, pigments, and phytonutrients, including potassium, zinc, magnesium, iron, and calcium. According to USDA National Nutrient Database, the green leafy vegetable is a source of vitamins like folate, niacin, vitamin A, vitamin B6, vitamin C, vitamin K, and contains traces of the rest of the essential vitamins. Other important elements, including thiamine and riboflavin, which are used in various reactions in our body, are also found in this green, leafy vegetable. The best part is that spinach is very low in calories and has no fat content.
Health Benefits of Spinach
Spinach plays many important roles in helping to maintain a healthy body. The various health benefits include the following.
Helen M Rasmussen, a researcher at the Cambridge University, in her 2013 report published in the Clinical Interventions in Aging revealed that spinach is a rich source of beta-carotene, lutein, and xanthene, all of which are beneficial for eyesight. Beta-carotene, in raw spinach, helps boost eye health. It can also prevent vitamin A deficiencies, itching eyes, eye ulcers, and dry eyes. The anti- properties of these greens can also reduce the puffiness or irritation in the eyes.
The lutein and zeaxanthin present in spinach both act as strong conditions., thus preventing the eyes from the harsh effects of UV rays that can lead to cataracts. They also reduce the impact of free radicals, which can be a major cause of cataracts and other eye
AMD or Retinitis pigmentosa is responsible for causing blindness, which is due to the degeneration of lutein and xanthene that are a central part of the retina. In a paper titled, ‘Age‐related macular degeneration and recent developments’, published in the Post Graduate Medical Journal, it was revealed that patients with AMD, must consume fresh green leafy vegetables, specifically spinach because it contains carotenoids. It also contains a wealth of antioxidants that reduce the harmful effects of free radicals, which are known to negatively impact vision and cause age-related conditions like glaucoma and macular degeneration as well.
Provides Neurological Benefits
Fernando Gómez-Pinilla, a researcher at the Department of Neurosurgery and high anti-oxidant capacity has been associated with the mitochondrial activity, responsible to influence cognitive function. Several components of this vegetable like potassium, folate, and various antioxidants are known to provide neurological benefits to people who regularly consume it. Folate helps to reduce the occurrence of Alzheimer’s disease, so the consumption of spinach might be a good idea for people who are at risk of neural or cognitive decline. Potassium is an integral part of brain health as well, and it has been linked to increased blood flow to the brain and heightened cognition, concentration, and neural activity.Science, University of California, US, suggests that spinach with a
Relieves Symptoms of Hemophilia
Vitamin K-rich spinach helps in blood clotting by producing prothrombin and it thus helps relieve symptoms hemophilia. It is great for controlling excessive bleeding and it also keeps the liver functioning by stimulating the production of glycogen. However, if you are taking an Registered Dietitian and monitor Vitamin K intake while taking Warfarin.such as Warfarin (brand name is Coumadin), it is advised to not increase your leafy green intake. You should discuss your current intake with your health care provider or
Maintains Blood Pressure
Spinach has a very high content of potassium and no sodium content in its raw form prior to preparation. This composition of minerals is very beneficial for high blood pressure patients as potassium lowers and sodium raises the blood pressure. Folate present in spinach also contributes to the reduction of and relaxes blood vessels, while maintaining proper blood flow. By reducing blood pressure and relaxing the tension of vessels and arteries, you can reduce stress on the system and increase oxygenation to the body’s organ systems for optimal functionality.
Factor Coenzyme-Q10 (C0-Q10), which is an antioxidant present in spinach, plays an important role in strengthening muscles, especially heart muscles which continuously pump blood to all parts of the body. C0-Q10 can be used to prevent many cardiovascular diseases like hyperlipidemia, heart failure, hypertension, and coronary heart disease.
Helps in Bone Mineralization
Spinach is a good source of Vitamin K, which functions in retaining calcium in the bone matrix, thereby leading to bone mineralization. Apart from this, other minerals like manganese, copper, magnesium, zinc, and phosphorus also help in building up strong bones. This, in turn, can help prevent an individual from developing osteoporosis. These minerals are also essential for maintaining healthy teeth and nails.
Helps Aid the Digestive System
According to a paper titled, ‘Antiulcer Activity of Aqueous Extract of Spinacia Oleracia in Rats’, published in the International Journal of Research in Pharmacy and Chemistry, spinach has the ability to protect the mucous membrane of the stomach, thereby decreasing the occurrence of gastric ulcers. Furthermore, the glycoglycerolipids found in spinach can boost the strength of the digestive tract lining, thereby preventing any unwanted inflammation in that part of the body.
Helps with Fetal Development
Folate found in spinach is needed by a growing fetus and helps aid in the proper development of the nervous system. Defects like cleft palate or spina bifida may occur due to a deficiency of folate. The high levels of vitamin A in it are advised to be consumed in recommended daily amounts by the mother. Vitamin A is required for proper lung development of the fetus and can be transferred during breastfeeding, so spinach consumption is recommended to be continued after birth.
There are many anti-inflammatory compounds found in spinach; more than a dozen, in fact. They are classified into the category of methylenedioxy flavonoid glucuronides, and spinach is one of the most powerful vegetables when it comes to reducing inflammation throughout the body. This not only means protecting the heart but also reducing the inflammation and pain associated with conditions like arthritis and gout, which afflict millions of people around the world.
Spinach is made up of various important constituents that have been found to be promising in the prevention of various kinds of cancer. These include bladder, prostate, liver and lung cancers. Different constituents in spinach like folate, tocopherol, and chlorophyllin act via different mechanisms to protect patients suffering from cancer.
Recent studies have revealed that it is very effective against aggressive prostate cancer, and this has been linked to epoxyxanthophylls, which are unique carotenoids, along with neoxanthin and violaxanthin that directly reduce tumorous activity and the spread of cancer throughout the body.
Different phytonutrients and pigments have been shown to protect the skin from the harmful rays of the sun, including UV rays. These not only protect but also repair the damaged genes to some extent, thereby preventing skin cancer in the long run.
Proteins for Infant Growth
‘Popeye, the Sailor Man’ is known for his obsession with spinach. The cartoon was deliberately aimed to convince children to eat spinach and get strong. Infants are advised to be fed spinach, which will give them protein, vitamins, minerals, and phytonutrients. These nutrients result in proportionate development in their essential growing stages.
Word of Caution
Those who are receiving dialysis due to End Stage Renal Disease are advised to consume a diet low in potassium and phosphorus, therefore spinach intake is to be limited and discussed with your Registered Dietitian. Also, those who are on anti-coagulant are not advised to increase their spinach intake, but rather keep spinach intake, if any, the same prior to taking Warfarin.
