Oranges are an excellent source of vitamin C and flavonoids. One orange (130 grams) supplies nearly 100 percent of the recommended daily dietary intake of vitamin C.

When you eat a whole orange, it provides good dietary fiber. Leave in the pith (the white matter under the peel) as much as possible as the pith contains the highest amount of valuable bioflavonoids and other anti-cancer agents.

In addition, oranges are a good source of vitamin A, the B vitamins, amino acids, beta-carotene, pectin, potassium, folic acid, calcium, iodine, phosphorus, sodium, zinc, manganese, chlorine and iron.

Health Benefits

An orange packs over 170 different phytonutrients and more than 60 flavonoids, many of which have been shown to have anti-inflammatory, anti-tumour and blood clot inhibiting properties, as well as strong anti-oxidant effects.

The combination of the high amount of anti-oxidant (vitamin C) and flavonoids in oranges makes it one of the best fruits in helping to promote optimal health.

Arteriosclerosis: Regularly consuming vitamin C retards the development of hardening of the arteries.

Cancer prevention: A compound in oranges called liminoid, has been found to help fight cancers of the mouth, skin, lung, breast, stomach and colon. The high vitamin C content also acts as a good anti-oxidant that protects cells from damages by free radicals.

Cholesterol: The alkaloid synephrine found under the orange peel can reduce the liver’s production of cholesterol. Whereas the anti-oxidant fights oxidative stress that is the main culprit in oxidizing the LDLs in our blood.

Constipation: Even though the orange “tastes acidic”, it actually has an alkaline effect in the digestive system and helps stimulate the digestive juices, relieving constipation.

Damaged sperms, repair: An orange a day is sufficient for a man to keep his sperms healthy. Vitamin C, an anti-oxidant, protects sperms from genetic damage that may cause a birth defect.

Heart disease: A high intake of flavonoids and vitamin C has been known to halve the risk of heart diseases.

High blood pressure: Studies have shown that a flavonoid called hesperidin in oranges can lower high blood pressure.

Immune system: The strong content of vitamin C stimulates white cells to fight infection, naturally building a good immune system.

Kidney stones, prevent: Drinking orange juice daily can significantly drop the risk of formation of calcium oxalate stones in the kidney.

Skin: The anti-oxidant in orange help protect the skin from free radical damage known to cause signs of aging.

Stomach ulcer: Consuming vitamin C rich foods helps to lower the incidence of peptic ulcers and in turn, reduce the risk of stomach cancer.

Viral infections, protection against: The abundance of polyphenols have been shown to provide protection against viral infections.

Several studies suggest that cinnamon may have a regulatory effect on blood sugar, making it especially beneficial for people with Type 2 diabetes.

In some studies, cinnamon has shown an amazing ability to stop medication-resistant yeast infections.

In a study published by researchers at the U.S. Department of Agriculture in Maryland, cinnamon reduced the proliferation of leukemia and lymphoma cancer cells.

It has an anti-clotting effect on the blood.

In a study at Copenhagen University, patients given half a teaspoon of cinnamon powder combined with one tablespoon of honey every morning before breakfast had significant relief in arthritis pain after one week and could walk without pain within one month.

When added to food, it inhibits bacterial growth and food spoilage, making it a natural food preservative.

One study found that smelling cinnamon boosts cognitive function and memory.

Researchers at Kansas State University found that cinnamon fights the E. coli bacteria in unpasteurized juices.

It is a great source of manganese, fiber, iron, and calcium.

Spinach Nutrition

Spinach and other dark leafy greens like kale, collards, Swiss chard, turnip greens and bok choy are loaded with calcium, folic acid, vitamin K and iron.

Spinach is also rich in vitamin C, fiber and carotenoids. Add its lutein and bioflavanoids and spinach is a nutritional powerhouse.

Why Eat Spinach?

Spinach nutrition is amazing. The calcium content in spinach and the other dark leafy greens mentioned above strengthens bones.

The A and C vitamins in spinach plus the fiber, folic acid, magnesium and other nutrients help control cancer, especially colon, lung and breast cancers. Folate also lowers the blood levels of something called homocysteine, a protein that damages arteries. So spinach also helps protect against heart disease.

The flavonoids in spinach help protect against age related memory loss.

Spinach’s secret weapon, lutein, makes it one of the best foods in the world to prevent cataracts, as well as age related macular degeneration, the leading cause of preventable blindness in the elderly. Foods rich in lutein are also thought to help prevent cancer.
