Potassium
Artichokes are an under-recognized source of potassium, a mineral that's vital to maintaining normal heart rhythm, fluid balance, muscle and nerve function. One medium Artichoke provides more than 400 milligrams of potassium, about as much as a small banana. There is strong evidence that a diet rich in potassium is linked to reduced risk of stroke. Potassium also blunts the effects of salt on blood pressure.
Magnesium
Magnesium is used in building bones, manufacturing proteins, releasing energy from muscle storage, and regulating our body temperature. Many adults especially women aren't getting enough of this mineral. Artichokes are a good source.
Vitamin C
Artichokes are an excellent source of vitamin C, a water-soluble vitamin that functions as a potent antioxidant. Vitamin C is vital for a healthy immune system. It also is important in forming collagen, a protein that gives structure to our bones, cartilage, muscle and blood vessels. Vitamin C also aids in the absorption of iron.
Dietary Fiber
Found only in plant foods, fiber helps maintain a healthy digestive system, lowers blood cholesterol, reduces the risk of heart disease and may prevent certain types of cancer. Fiber also works to keep blood-sugar levels stable, which is especially important for people with diabetes. It can also help us feel full, aiding in weight control. Artichokes are fiber rich, providing 10.3 grams in one Artichoke (120 grams).
Protein
The USDA 2005 Dietary Guidelines for Americans recommend eating more plant-based protein in place of animal-based protein as a way to help reduce saturated fat and cholesterol intake. With no fat, cholesterol or trans fat, Artichokes are a healthful source of protein. One medium Artichoke provides four grams.
