Walnuts have been a beloved snack for thousands of years.
In ancient Rome, people called them by their Latin name, Juglansregia, which means “Jupiter’s royal acorn.” Walnuts originated in Persia and spread through Asia and Europe.
Spanish missionaries brought them to California in the 1700s.
Today, most of the walnuts in the U.S. are grown in California, but some are grown in the Midwest as well. English walnuts, also known as Persian walnuts, are members of the Juglandaceae family, with pecans and hickory as close relatives. They grow in a tan shell about the size of a golf ball with a seam around the center.

Split the shell at the seam, and inside you’ll find the bumpy, golden brown nut. Walnut skin sometimes has a slightly bitter flavor, but the nut itself is mild, earthy, and a little tangy. Nutritional Profile One serving of walnuts is 1 ounce, or about 7 walnuts. A serving of walnuts has: 185 calories 2.5 grams of monounsaturated fat 1.7 grams of saturated fat 4.3 grams of protein 3.9 of carbohydrates 1.9 grams of fiber .7 grams of sugar.
That small serving size packs a big nutritional benefit. Here are the vitamins and minerals you'll get in an ounce of walnuts: Up to 3% of your daily recommended amount of calcium Up to 10% of your daily iron Up to 5% of your daily potassium Up to 14% of your daily magnesium 7% of your daily folate What Walnuts Can Do for You Walnuts have a wealth of the good kind of fats -- polyunsaturated fats, which are better for you than saturated fats. They also have a high amount of omega-3 fatty acids.

Studies have shown that eating walnuts can help lower LDL (“bad”) cholesterol in particular, but also lower your cholesterol overall. Cholesterol can form plaque inside your arteries, but eating walnuts can help keep your artery walls healthy. Walnuts also have been shown to ease the type of inflammation that leads to heart disease, and they may help lower your chances of a blood clot that could cause a heart attack. Two large studies found that five servings of nuts a week can reduce your risk of heart disease by as much as 50%. And early studies show that walnuts may cut your odds of some types of cancer. They have a type of acid called ellagic acid, which is also found in pecans. Bacteria in your stomach and intestines change this acid into compounds with antioxidant power, which may help ward off cancer. But more research is needed to know for sure.
