You’ve heard the argument for getting your 5-7 servings of fruits and vegetables a day, but maybe you need another reason to choose an apple over a Snickers bar and steamed veggies over buttered bread. In addition to weight loss, clearer skin, and a better feeling body, fruits and vegetables contain natural antioxidants that fight aging. The free radical theory of aging states that we age because our cells accumulate free radical damage from exposure to smoking, air pollutants, the sun, and chemicals. To fight premature aging of the cells you can eat foods high in antioxidants that counteract and fight free radicals.
Next time you go shopping toss these antioxidant rich foods in your basket and eat to good health!
This tree-like veggie is known in the health community for providing the most concentrated source of vitamin C, a premier antioxidant nutrient. Vitamin C provides support of the body’s oxygen metabolism and lowers the risk of chronic inflammation and cancer risk. If that wasn’t enough, broccoli contains several carotenoids, which function as key antioxidants.
You may skip over these fruits, but apricots pack a powerful punch of antioxidants including carotenoids and vitamin A, which is needed for cell growth and immune system function. This fruit is also good for your vision, full of potassium, and contains a healthy serving of fiber.
These fruits may already be your favorite topping for yogurt and granola or a sweet treat after dinner, but these small berries provide the body with specific antioxidants that can’t be found in any other food. In addition to high levels of vitamin C and anthocanines, raspberries contain ellagitannins, which make up 50 percent of a raspberries antioxidant effect.
This tiny fruit is packed full of queritrin and ellagic acid, which fight off the body’s cancerous cells to prevent cancer from developing. Try to eat an organic version of this fruit or drink cherry juice for your daily dose of these cancer-fighting antioxidants.
Contrary to the popular belief that this water-packed summer treat is made up of only water and sugar, watermelon is actually a nutrient dense food that is full of antioxidants. This melon is full of vitamin C and lycopene, which is associated with a decreased risk of prostate cancer.
This yummy vegetable contains some of the most powerful, polyphenol antioxidants including quercetin, which fights against cancer and heart disease, rutin which is anti inflammatory and anti-allergenic, and anthocyanins that help with urinary tract health, memory function, and graceful aging.
Probably one of the most commonly known antioxidant rich foods, these berries do pack a powerful punch of health, especially considering their small size. One cup of natural, wild blueberries contains more antioxidant capacity than 20 other fruits and vegetables. For blueberries their antioxidant power comes from the blue pigment in the berries, which protects against inflammation, Alzheimer’s disease, and other degenerative diseases.
This leafy green is already loved for its high levels of fiber, potassium, and multiple vitamins. In addition to being full of healthy goodness, spinach is full of the carotenoids luten and zeaxanthin, which protect the eyes from damage, fight against cataracts, and age-related macular degeneration.
9. Kidney Beans
You may already love beans as a source of protein, fiber, and nutrients, but kidney beans are also exceptionally rich in flavonoids, a class of antioxidants that helps fight aging and the presence of free radicals in the body.
You may already know that oranges are high in vitamin C, but this particular vitamin is the primary water-soluble antioxidant in the body. It works to prevent damage inside and outside the cells to prevent colon cancer. In addition it can reduce the severity of inflammatory conditions like asthma, osteoarthritis, and rheumatoid arthritis.
gPosted by Crisha Alyziah Miller -When you have iron-deficiency, your cells can’t get enough oxygen. How can you tell if your levels are a little low? Be on the lookout for these 10 warning signs.
Iron is crucial to biologic functions, including respiration, energy production, DNA synthesis, and cell proliferation. Although the prevalence of iron-deficiency anemia has declined somewhat recently, iron deficiency continues to be the top-ranking cause of anemia worldwide.
The human body has evolved to conserve iron in several ways, including the recycling of iron after the breakdown of red cells and the retention of iron in the absence of an excretion mechanism.
However, since excess levels of iron can be toxic, its absorption is limited to 1 to 2 mg daily, and most of the iron in the body (about 25 mg per day) is recycled by macrophages that phagocytose senescent erythrocytes. The latter two mechanisms are controlled by the hormone hepcidin, which maintains total-body iron within normal range, avoiding both iron deficiency and excess.
Hepcidin is a peptide hormone that is synthesized primarily in the liver. It functions as an acute-phase reactant that adjusts fluctuations in plasma iron levels by binding to and inducing the degradation of ferroportin, which exports iron from cells. In iron deficiency, the transcription of hepcidin is suppressed. This adaptive mechanism facilitates the absorption of iron and the release of iron from body stores.
In most cases, iron resistance is due to disorders of the gastrointestinal tract. Partial or total gastrectomy or any surgical procedure that bypasses the duodenum can cause resistance to oral iron. Laparoscopic Roux-en-Y gastric bypass, which is performed in selected obese patients to reduce caloric intake and to correct diabetes, is an emerging cause of iron deficiency and anemia because the procedure effectively removes an active iron absorption site from the digestive process and increases gastric pH. Helicobacter pylori infection decreases iron absorption because the microorganism competes with its human host for available iron, reduces the bioavailability of vitamin C, and may lead to microerosions that cause bleeding. Since it is estimated that half the world’s population is infected with H. pylori, clinicians should be aware of the possibility of infection and provide treatment in order to eradicate this source of iron-resistant iron-deficiency anemia.
Patients with malabsorption and genetic iron-refractory iron-deficiency anemia may require intravenous iron. Intravenous administration is also preferred when a rapid increase in hemoglobin level is required or when iron-deficiency anemia caused by chronic blood loss cannot be controlled with the use of oral iron, as is the case in patients with hereditary hemorrhagic telangiectasia. Active inflammatory bowel disease is an emerging indication for the use of intravenous iron; oral iron is not only ineffective but may also increase local inflammation. Intravenous iron is essential in the management of anemia in patients with chronic kidney disease who are receiving dialysis and treatment with erythropoiesis-stimulating agents.
