We all know that Popeye made himself super strong by eating spinach, but you may be surprised to learn that he may also have been protecting himself against osteoporosis, heart disease, colon cancer, arthritis, and other diseases at the same time.
Phytonutrient Flavonoids for Optimal Health
Researchers have identified at least 13 different flavonoid compounds in spinach that function as antioxidants and as anti-cancer agents. The anticancer properties of these spinach flavonoids have been sufficiently impressive to prompt researchers to create specialized spinach extracts that could be used in controlled studies. These spinach extracts have been shown to slow down cell division in stomach cancer cells (gastric adenocarcinomas), and in studies on laboratory animals, to reduce skin cancers (skin papillomas). A study on adult women living in New England in the late 1980s also showed intake of spinach to be inversely related to incidence of breast cancer.
Spinach Carotenoid Combats Prostate Cancer
A carotenoid found in spinach and other green leafy vegetables fights human prostate cancer two different ways, according to research published in the theJournal of Nutrition. The carotenoid, called neoxanthin, not only induces prostate cancer cells to self-destruct, but is converted in the intestines into additional compounds, called neochromes, which put prostate cancer cells into a state of stasis, thus preventing their replication.Spinach Flavonoid Combats Ovarian Cancer
For atherosclerosis and diabetic heart disease, few foods compare to spinach in their number of helpful nutrients. Spinach is an excellent source of vitamin C andvitamin A, the latter notably through its concentration of beta-carotene. These two nutrients are important antioxidants that work to reduce the amounts of free radicals in the body; vitamin C works as a water-soluble antioxidant and beta-carotene as a fat-soluble one. This water-and-fat-soluble antioxidant team helps to prevent cholesterol from becoming oxidized. Oxidized cholesterol is able to stick to and build up in blood vessel walls, where it can cause blocked arteries, heart attack or stroke. Getting plenty of vitamin C and beta-carotene can help prevent these complications, and a cup of boiled spinach can provide you with 294.8% of the daily value (DV) for vitamin A along with 29.4% of the DV for vitamin C.
Spinach is also an excellent source of folate. Folate is needed by the body to help convert a potentially dangerous chemical called homocysteine that can lead to heart attack or stroke if levels get too high, into other benign molecules. In addition, spinach is an excellent source of magnesium, a mineral that can help to lower high blood pressure and protect against heart disease as well.
Promotes Gastrointestinal Health
The vitamin C and beta-carotene in spinach help to protect the colon cells from the damaging effects of free radicals. And the folate in spinach helps to prevent DNA damage and mutations in colon cells, even when they are exposed to cancer-causing chemicals. Studies show that people who eat foods high in vitamin C, beta-carotene, and/or folate are at a much lower risk of getting colon cancer than those who don't.
Anti-Inflammatory Nutrients
The nutrients in spinach can also help with conditions in which inflammation plays a role. For example, asthma, osteoarthritis, osteoporosis and rheumatoid arthritis are all conditions that involve inflammation. Since beta-carotene, vitamin C and vitamin K all have anti-inflammatory properties, they can be helpful for reducing symptoms in some patients. In addition, the magnesium and riboflavin in spinach, two nutrients of which it is an excellent source, may help to reduce the frequency of migraine attacks in people who suffer from them.
A Smarter Brain with Spinach
In animal studies, researchers have found that spinach may help protect the brain from oxidative stress and may reduce the effects of age-related related declines in brain function. Researchers found that feeding aging laboratory animals spinach-rich diets significantly improved both their learning capacity and motor skills.
Vitamin E-rich Leafy Greens Slow Loss of Mental Function
Mental performance normally declines with age, but the results of Chicago Health and Aging Project (CHAP) suggest that eating just 3 servings of green leafy, yellow and cruciferous vegetables each day could slow this decline by 40%, suggests a study in the journal Neurology (.Morris MC, Evans DA, et al.) Compared to people who consumed less than one serving of vegetables a day, people who ate at least 2.8 servings of vegetables a day saw their rate of cognitive decline slow by roughly 40%. This decrease is equivalent to about five years of younger age,
said lead author Martha Clare Morris, ScD, with Rush University Medical Center in Chicago.
The prospective cohort study, funded by the National Institute of Aging, used dietary data from 3,718 participants (62% female, 60% African American, average age 74). Mental function was assessed with four different tests: the East Boston Tests of immediate memory and delayed recall, the Mini-Mental State Examination, and the Symbol Digit Modalities Test, taken at the start of the study and then again after 3 and 6 years.
After adjusting the results for potential confounders such as age, sex, race, education, and cardiovascular risk factors, the researchers found that consuming an average of 2.8 vegetable servings each day was associated with a 40% decrease in cognitive decline, compared to those who ate an average of less than one (0.9) serving a day. Of the different types of vegetables, green leafy vegetables had the strongest association,
said Dr. Morris.
Better Eyesight from Spinach
Lutein, a carotenoid protective against eye diseases such as age-related macular degeneration and cataract, is found in green vegetables, especially spinach, as well as kale and broccoli. But egg yolks, although they contain significantly less lutein than spinach, are a much more bioavailable source whose consumption increases lutein concentrations in the blood many-fold higher than spinach,shows a human study published in the Journal of Nutrition.
Iron for Energy
Cooked spinach is an excellent source of iron, a mineral that it particularly important for menstruating women, who are more at risk for iron deficiency. Boosting iron stores with spinach is a good idea, especially because, in comparison to red meat, a well-known source of iron, spinach provides iron for a lot less calories and is totally fat-free. Iron is an integral component of hemoglobin, which transports oxygen from the lungs to all body cells, and is also part of key enzyme systems for energy production and metabolism. And, if you're pregnant or lactating, your needs for iron increase. Growing children and adolescents also have increased needs for iron. In one cup of boiled spinach, you'll be provided with 35.7% of the daily value for iron.
So while spinach probably won't make you super strong the minute you eat it, as it did for Popeye, it will promote your health and vitality in many other ways. It seems like Popeye was pretty smart after all.
You poor thing! I am laughing over the juice flying everywhere...that is something I would do!! :) I think I will just start making these smoothies without the protein powder. It adds a funky taste! Spinach definitely is a SUPERFOOD!
ReplyDeleteYou are really inspiring me girlfriend!! I'm going to be making a healthy happpenings grocery trip later!!
ReplyDeleteHi Tiff! I'm so excited you started a blog...and I'm already learning why I drink those strange looking green drinks every day!
ReplyDeleteCan't wait to keep reading!
I can testify that it IS very yummy!
