Spinach Juice and SmoothiesApril 2, 2012 Written by JP [Font too small?]
A simple addition or substitution can make a profound difference in the overall quality of your diet. If you enjoy freshly made juice or homemade smoothies, you can very easily improve the nutrient density of these beverages by tossing a handful of raw spinach into the mix. The beauty of this strategy is that you’re unlikely to taste the spinach at all, though you’ll probably notice its chlorophyll inspired hue. But, you can be certain that your body will be keenly aware of it.
I’m a strong believer in the importance of understanding why you’re making a change before you actually make it. Part of the reason I encourage you to add more raw spinach to your diet is because of its potent mix of nutrients. A cup of uncooked spinach only contains 7 calories. However, what it lacks in caloric content, it more than makes up for in minerals and vitamins such as folic acid, potassium and Vitamin K. All three of these nutrients are acknowledged as vitally important for the promotion of cardiovascular health. And, since heart disease is the leading cause of mortality around the world, it makes sense to eat more foods that may protect against it.
Taking a closer look at the composition of spinach reveals some additional benefits that extend beyond the cardiovascular system. For starters, eating spinach on a regular basis has been shown to reduce two contributors to degenerative diseases including cancer: DNA instability and lipid peroxidation. Raw spinach may also promote a healthier mood because it’s rich in folate, the naturally occurring B-vitamin. Those living with depressive disorders are often deficient in this essential nutrient. The fact that spinach is one of the best dietary sources of Vitamin K likewise bodes well for various organs and systems in the body. While it’s widely known that Vitamin K supports strong bones, current research also indicates that K plays an integral role in brain functioning. A review appearing in the February 2012 issue of the journal Biofactors explains that Vitamin K is necessary for the production of a type of fat (sphingolipids) present in the brain that may counteract “age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s disease”.
Whenever possible, I suggest using organic spinach. Conventionally grown spinach is one of the top offenders in terms of detectable pesticide residues. What’s more, the organic version of this green leafy vegetable has recently been proven to contain higher levels of protective antioxidants, including flavonoids and Vitamin C. Flavonoids are one of the key, nonnutritive components of spinach which support cardiovascular health by improving circulation (endothelial function and flow-mediated dilation) and, thereby, lowering systolic blood pressure.
