POTATOES
Known by most as a traditional Irish food, particularly for the part they played in causing the great emigration to the United States from Ireland during the Irish Potato Famine of the 1840s, potatoes are actually a New World vegetable of the nightshade family. Many potato varieties exist, some developed by the Inca Indians in Peru, who were already cultivating potatoes by 200 B.C. The part of the potato that we eat is known as the “tuber;” this word describes the characteristic, thickened underground stem of the potato plant. VarietiesSome of the most popular types of the many varieties of potatoes are described below. Russet This is the most popular potato in the United States. It is also known as the Idaho or baking potato. Most are grown in the Northwest, and they are available year-round. These potatoes are high in starch and are characterized by netted brown skin and white flesh. Russets are light and fluffy when cooked, making them ideal for baking and mashing. They are good for frying and roasting, too. Round white Round whites are grown and used most often in the eastern United States. They are available year-round. Round whites are medium in starch level and have smooth, light tan skin with white flesh. These potatoes are creamy in texture and hold their shape well after cooking. Regarded as an all-purpose potato, round whites are very versatile and work well in just about every potato preparation. Long white, or white rose These are grown primarily in California and are most readily available spring through summer. Long whites are oval-shaped, medium in starch level, and have thin, light tan skin. They have a firm, creamy, almost waxy texture when cooked, and hold their shape well. These all-purpose potatoes are very versatile, and work well in just about every potato preparation. Round red These potatoes are available mostly in late summer and early fall. They are easy to recognize with their red skin and white flesh. Red potatoes have a firm, smooth, and moist texture, making them well suited for salads, roasting, boiling and steaming. They are often referred to as “new potatoes”; however, technically, “new” refers to any variety of potato that is harvested when its skin is reddish, before reaching maturity. Yellow flesh These potatoes are very popular in Europe and increasingly popular in the United States, although they are still not grown in large quantities. Yukon gold is a variety of yellow-flesh potato available in late summer and early fall. These potatoes have a dense, creamy texture. With their golden color, you can be fooled into thinking that they are already buttered. They are a good choice for mashed potatoes. Blue and purple These potatoes originated in South America and are not widely cultivated in the United States. Blue and purple potatoes are most commonly available in the fall. In the United States, they are often seen on the snack shelves of natural foods and grocery stores as chips. These relatively uncommon potatoes have a subtle nutty flavor and flesh that ranges in hue from dark blue or lavender to white. Microwaving preserves the color the best, but steaming and baking also work well. Potatoes are sold fresh, dehydrated, canned, frozen (mostly as French fries or hash browns), and, of course, there’s the familiar potato chip. Potato flour, also known as potato starch, is also available, and can be used as a binder in meat or vegetable patties. Dehydrated potato flakes and granules are used most often to make mashed potatoes. Some products require the addition of water, milk, and butter; others only require the addition of water. Dehydrated shredded, sliced, and diced potatoes are also available. These can be found in packaged convenience potato products, such as potatoes au gratin mixes. Preparation, uses, and tipsThere are many ways to enjoy potatoes. Just about every preparation, including mashed, works well with the potato skin intact; keeping the skin on also retains nutrients. Here are some tips on some of the most popular preparation techniques. Baked Oven baked Heat oven to 425ºF (220ºC). Pierce potato in several places so the steam can escape. Place potato on oven rack or baking sheet. Bake 40 to 55 minutes or until tender when pierced with a fork. Microwave-baked Pierce each potato several times so the steam can escape. Place in microwave oven and microwave on high until tender, turning potato over halfway. For medium-sized potatoes (about 5 ounces or 140g), microwave 3 1/2 to 4 1/2 minutes. For larger potatoes, (about 9 ounces or 255g), microwave 5 to 9 minutes. Mashed Stovetop preparation In a large saucepan, add cut-up potatoes to 2 inches (about 5cm) of boiling water, or just enough to cover them. Return to a boil. Reduce heat and cook, covered, about 12 minutes or until tender; drain. (If cooking whole potatoes, allow 30 to 40 minutes.) Using an electric hand-mixer or potato masher, mash potatoes. Mix in warmed milk, butter (if desired), salt, and pepper. Microwave-oven preparation In a microwave-safe dish, combine 1 1/2 pounds (about 680g) quartered potatoes and 3 Tbsp (45mL) water. Cover and microwave on high 12 to 14 minutes or until tender. Mash potatoes as described above and stir in warmed milk, butter (if desired), salt, and pepper. To reduce the fat and calorie content of mashed potatoes, try replacing the milk and butter with chicken or vegetable broth and buttermilk. Roasted Heat oven to 425ºF (220ºC). Toss cut-up potatoes with enough olive oil to coat lightly. Season with salt and pepper (or any seasoned salt). Arrange in an even layer on a lightly oiled shallow baking pan. Roast 20 to 30 minutes or until tender, moving them around occasionally. Hash browns In a large nonstick skillet, heat butter (or olive oil) over medium heat. Add coarsely shredded potatoes; cover, and cook until bottom is golden brown, adjusting heat as necessary. Turn potatoes over carefully to brown opposite side. Season with salt and pepper. Note: Turn only once for crisper potatoes. Nutritional HighlightsPotato (baked, w/skin), 1 potato (202g) *Foods that are an “excellent source” of a particular nutrient provide 20% or more of the Recommended Daily Value, based upon United States Department of Agriculture (USDA) guidelines. Foods that are a “good source” of a particular nutrient provide between 10 and 20% of the USDA Recommended Daily Value. Nutritional information and daily nutritional guidelines may vary in different countries. Please consult the appropriate organization in your country for specific nutritional values and the recommended daily guidelines. Health benefits and concernsCarbohydrate food is the most efficient fuel for energy production and can also be stored as glycogen in muscle and liver, functioning as a readily available energy source for prolonged, strenuous exercise. For these reasons, carbohydrates may be the most important nutrient for sports performance. Depending on training intensity and duration, athletes require up to 4.5 grams of carbohydrates per day per pound of body weight or 60 to 70 percent of total dietary calories from carbohydrates, whichever is greater. Including starchy vegetables in the diet is one good way to obtain these carbohydrates. Solanine is a substance found in nightshade plants, including tomatoes, white potatoes, all peppers (except black pepper), and eggplant. In theory, if it is not destroyed in the intestine, solanine could be toxic. A horticulturist, Dr. Norman Childers, hypothesized that some people with OA may not be able to destroy solanine in the gut, leading to solanine absorption resulting in OA. Eliminating solanine from the diet has been reported to bring relief to some arthritis sufferers in preliminary research. Researchers have never put this diet to a strict clinical test; however, the treatment continues to be used by some doctors in people who have OA. Proponents claim exclusion of solanine requires up to six months before potential effects can be seen. Totally eliminating tomatoes and peppers requires complex dietary changes for most people. In addition, even proponents of the diet acknowledge that many arthritis sufferers are not helped by using this approach. Therefore, long-term trial avoidance of solanine-containing foods may only be appropriate for people with severe cases of OA who have not responded to other natural treatments.
