Diet & Nutrition Everyone knows an apple is a better snack than potato chips, but many foods can help you improve your health by lowering your blood sugar levels and your weight. There are actually many foods with a high capacity for improving your overall health in several ways and also helping you to reverse a case of diabetes condition.One food you may never have given much thought to in your quest to stabilize your general body health is watercress. Watercress is a little leaf that packs a lot of power. It has a peppery taste and adds great texture to salads. Its distinctive mustard flavour gives a new dimension to a number of cooked dishes. This product is known to be one of the healthiest foods you can put into your body, so it's well worth your time to give it some consideration. Below are some of the health benefits of watercress:Maintain healthy bonesWhen we look at the nutritional line-up of watercress, we see just how dense it really is. It contains more iron than you'd get from a serving of spinach, as well as is a powerful dose of bone-strengthening calcium along with the supercharged antioxidant, vitamin C. Also, watercress contains vitamin K, which also fosters strong bones along with the calcium.Treating diabetesWatercress provides and will give you some vitamin A to keep your eyes strong and vitamin B to help ensure optimal metabolic function. Normally, one of the most overlooked ways to help diabetics with terrible nerve pain is the simple B vitamin. At just 11 calories per 3 cups of watercress, consider this a freebie in your diet. You can eat as much as you like and it will not impact your body weight. Although controlling a disease can be very challenging, diabetes is not a condition you must just live with. You can make simple changes to your daily routine and lower both your blood sugar levels and your weight.Cancer preventionThis green superfood has a unique chemical known as nasturtium, which is converted into an isothiocyanate known as PEITC. This has been shown in different scientific studies to slow down the growth of prostate, breast, and colon cancer cells. The components in watercress are also thought to reduce the risk of macular degeneration of the eye.Different studies have found that eating 85 grams of watercress per day significantly reduced cancer damage to white blood cells and increased the body's levels of cancer-fighting antioxidants. This has led scientists to believe that the vegetable may hamper the growth of cancer cells, or even kill them. This green superfood is best eaten raw, as heat can destroy the PEITC. Studies show that watercress may also help to reduce cancer formation by starving off tumor growth.Reduces damage to DNAPublished research in the American Journal of Clinical Nutrition, found that watercress was able to reduce the DNA damage found in cells. Also, those damaged cells were able to resist further DNA damage caused by free radicals. Damage to DNA is considered to be significantly involved in cancer.Very high source of iodineWatercress is a highly potent source of iodine for thyroid support. The thyroid gland is important for metabolism. A well-functioning thyroid gland is necessary for persons attempting to lose weight. Watercress would be very beneficial for people who are trying to increase their iodine intake.Lowers bad cholesterolOne study found that after eight weeks of watercress consumption, the participants had a 10% reduction in their blood triglyceride levels. That finding was significant because an elevated triglyceride level is a risk factor for cardiovascular disease.This simple green is unassuming and most times may only serve as garnish. However, it packs a great nutritional punch. So this season when you are thinking of something healthy and tasty to serve, why not think of a fresh salad with watercress. Its peppery taste is sure to perk up the flavour. Watercress deserves to be more than a garnish because it is so nutrient dense.This is the guest post from Anthony, a sport enthusiast and sports blogger at Stetsports.com – where he shares his experience doing outdoor sports and gym training.
