Grains are good for your health

On internet we read some ridiculous theories that grains are bad and that we should avoid them! Instead, grains are the superior food, and they should be the basis of our diet.

50% grains, 30% vegetables, fruits and legumes, 10% protein (dairy products, nuts, and very rare meat, fish and eggs), and 10% fat (unsaturated and polyunsaturated) 

Why Is it Important to Eat Grains, Especially Whole Grains?

    Eating grains, especially whole grains, provides health benefits. People who eat whole grains as part of a healthy diet have a reduced risk of some chronic diseases. Grains provide many nutrients that are vital for the health and maintenance of our bodies.

  • Health Benefitsplate of various grains

    • Consuming whole grains as part of a healthy diet may reduce the risk of heart disease.
    • Consuming foods containing fiber, such as whole grains, as part of a healthy diet, may reduce constipation.
    • Eating whole grains may help with weight management.
    • Eating grain products fortified with folate before and during pregnancy helps prevent neural tube defects during fetal development.
  • Nutrientssliced whole wheat bread

    • Grains are important sources of many nutrients, including dietary fiber, several B vitamins (thiamin, riboflavin, niacin, and folate), and minerals (iron, magnesium, and selenium).
    • Dietary fiber from whole grains or other foods, may help reduce blood cholesterol levels and may lower risk of heart disease, obesity, and type 2 diabetes. Fiber is important for proper bowel function. It helps reduce constipation and diverticulosis. Fiber-containing foods such as whole grains help provide a feeling of fullness with fewer calories.
    • The B vitamins thiamin, riboflavin, and niacin play a key role in metabolism – they help the body release energy from protein, fat, and carbohydrates. B vitamins are also essential for a healthy nervous system. Many refined grains are enriched with these B vitamins.
    • Folate (folic acid), another B vitamin, helps the body form red blood cells. Women of childbearing age who may become pregnant should consume adequate folate from foods, and in addition 400 mcg of synthetic folic acid from fortified foods or supplements. This reduces the risk of neural tube defects, spina bifida, and anencephaly during fetal development.
    • Iron is used to carry oxygen in the blood. Many teenage girls and women in their childbearing years have iron-deficiency anemia. They should eat foods high in heme-iron (meats) or eat other iron containing foods along with foods rich in vitamin C, which can improve absorption of non-heme iron. Whole and enriched refined grain products are major sources of non-heme iron in American diets.
    • Whole grains are sources of magnesium and selenium. Magnesium is a mineral used in building bones and releasing energy from muscles. Selenium protects cells from oxidation. It is also important for a healthy immune system.

    Whole grains: Hearty options for a healthy diet

    Find out why whole grains are better than refined grains and how to add more whole grains to your diet. By Mayo Clinic Staff
    Grains, especially whole grains, are an essential part of a healthy diet. All types of grains are good sources of complex carbohydrates and some key vitamins and minerals. Grains are also naturally low in fat. All of this makes grains a healthy option. Better yet, they've been linked to a lower risk of heart disease, diabetes, certain cancers and other health problems.
    The healthiest kinds of grains are whole grains. The 2010 Dietary Guidelines for Americans recommends that at least half of all the grains you eat are whole grains. Chances are you eat lots of grains already. But are they whole grains? If you're like most, you're not getting enough whole grains in your diet. See how to make whole grains a part of your healthy diet.

    Types of grains

    Also called cereals, grains and whole grains are the seeds of grasses cultivated for food. Grains and whole grains come in many shapes and sizes, from large kernels of popcorn to small quinoa seeds.
  • Whole grains. These are unrefined grains that haven't had their bran and germ removed by milling. Whole grains are better sources of fiber and other important nutrients, such as selenium, potassium and magnesium. Whole grains are either single foods, such as brown rice and popcorn, or ingredients in products, such as buckwheat in pancakes or whole wheat in bread.
  • Refined grains. Refined grains are milled, a process that strips out both the bran and germ to give them a finer texture and extend their shelf life. The refining process also removes many nutrients, including fiber. Refined grains include white flour, white rice, white bread and degermed cornflower. Many breads, cereals, crackers, desserts and pastries are made with refined grains, too.
  • Enriched grains. Enriched means that some of the nutrients lost during processing are added back in. Some enriched grains are grains that have lost B vitamins added back in — but not the lost fiber. Fortifying means adding in nutrients that don't occur naturally in the food. Most refined grains are enriched, and many enriched grains also are fortified with other vitamins and minerals, such as folic acid and iron. Some countries require certain refined grains to be enriched. Whole grains may or may not be fortified.

Choosing whole grains

Eat whole grains rather than refined grains as often as possible. Whole-grain versions of rice, bread, cereal, flour and pasta can be found at most grocery stores. Many whole-grain foods come ready to eat. These include a variety of breads, pastas and cereals.
Examples of whole grains include:
  • Barley
  • Brown rice
  • Buckwheat
  • Bulgur (cracked wheat)
  • Millet
  • Oatmeal
  • Popcorn
  • Whole-wheat bread, pasta or crackers
  • Wild rice
It's not always easy to tell what kind of grains a product has, especially bread. For instance, a brown bread isn't necessarily whole wheat — the color may come from added coloring. If you're not sure something has whole grains, check the product label or the Nutrition Facts panel. Look for the word "whole" on the package, and make sure whole grains appear among the first items in the ingredient list.
What about whole-wheat white bread?
It may seem like it doesn't add up, but actually white whole-wheat bread is made with whole grains, just as is regular whole-wheat bread. White whole-wheat bread also is nutritionally similar to that of regular whole-wheat bread. So if you prefer the taste and texture of white bread but want the nutritional benefits of whole wheat, choose white whole-wheat bread — not regular, refined white bread.
A word of caution
If all of the grains you eat are whole grains, you may need to take extra care to get sufficient folic acid, a B vitamin. This is because whole grains are not a natural source of folate, and some may not be fortified with folate. Look for whole grains that have been fortified with folic acid, such as some ready-to-eat cereals. Folate is also found in other foods, including fruits, vegetables and legumes. Folic acid is especially important if you're a woman who could become pregnant or is pregnant.

How to enjoy more whole grains in your diet

Try these tips to add more whole grains to your meals and snacks:
  • Enjoy breakfasts that include whole-grain cereals, such as bran flakes, shredded wheat or oatmeal.
  • Substitute whole-wheat toast or whole-grain bagels for plain bagels. Substitute low-fat bran muffins for pastries.
  • Make sandwiches using whole-grain breads or rolls. Swap out white-flour tortillas with whole-wheat versions.
  • Replace white rice with kasha, brown rice, wild rice or bulgur.
  • Feature wild rice or barley in soups, stews, casseroles and salads.
  • Add whole grains, such as cooked brown rice or whole-grain bread crumbs, to ground meat or poultry for extra body.
  • Use rolled oats or crushed bran cereal in recipes instead of dry bread crumbs.
Eating a variety of whole grains not only ensures that you get more health-promoting nutrients but also helps make your meals and snacks more interesting.

The 11 Healthiest Whole Grains

Don’t nix carbs. Just make sure you’re eating the good ones and eliminating the bad.

The 11 Healthiest GrainsCarbs get a bad rap because so many Americans are eating the bad ones—refined carbohydrates in white bread, candy, cookies, sugary cereals, and all sorts of other junk food and drinks. In fact, research has shown that 95 percent of the grains we eat are refined. Eating too many foods with these adulterated ingredients won’t just make you fat; it’ll also raise your risk of heart disease and diabetes. And raise your levels of blood fats called triglycerides, putting you on the fast track for a heart attack or stroke. The good news is working the healthiest grains into your diet can help prevent or reverse these health problems.
Healthy, whole-grain foods are made from cereal grains that include the whole kernel. Research shows they can protect you from ticker trouble, diabetes, colon cancer, and possibly asthma and Alzheimer’s disease.

Whole Wheat
This one is pretty easy, as long as you don’t let food marketers trick you. It can be readily found in bread and pasta products, but make sure the label says “100 percent whole wheat.” Terms like “multigrain” and “wheat” don’t cut it. As when you’re shopping for any whole-grain product, look at the ingredients and make sure the whole grain is at or near the top of the list. Each serving should contain at least 2 or 3 grams of fiber.

Whole Oats/Oatmeal
Oats are particularly rich in avenanthramide, an antioxidant that protects the heart. When you’re shopping for this whole grain, whether you see the word “whole” or not doesn’t matter, the way it does with wheat products. Oats in the ingredients list means the product is made from whole oats. But if you are buying something like instant oatmeal, avoid those that contain high-fructose corn syrup. A study this year found that ingredient was a source of mercury contamination in oatmeal. We suggest sticking to the good old-fashioned unsweetened kind and mixing in a little fruit or honey.

 Bulgur
For all practical purposes, bulgur is considered a whole grain, even though up to 5 percent of its bran may be removed during processing. It’s so good for you, though, we’re putting it on the list. The grain, which is used to make tabbouleh salad, is a great source of iron and magnesium. The fiber and protein powerhouse (a cup contains nearly 75 percent of the dietary fiber you need for the day, and 25 percent of the protein you should get) can be used in salads or tossed in soups. It’s ready in minutes.

Brown Rice
When you choose white rice over brown, around 75 percent of rice’s nutrients—including nearly all the antioxidants, magnesium, phosphorus, and B vitamins contained in the healthy bran and germ—are left on the milling-room floor. Always opt for brown rice, and that includes brown aromatic varieties like basmati and jasmine. Get even more exotic with red and black rice, both of which are considered whole grains and are high in antioxidants. Though technically a grass, wild rice is also considered a whole grain and is rich in B vitamins, such as niacin and folate.

 Whole-Grain Barley
Eating a half-cup of whole barley regularly during a 5-week period cut participants’ cholesterol levels by nearly 10 percent when compared to other participants who went without barley in a USDA study. Add raisins or dried apricots to quick-cooking barley, and serve it as a side dish. Just make sure it’s whole-grain barley, not “pearled,” which means the bran and germ have been removed.

 Whole Rye
According to nutritional research from the nonprofit Organic Center, rye has more nutrients per 100-calorie serving than any other whole grain. It has four times more fiber than standard whole wheat and provides you with nearly 50 percent of your daily recommended amount of iron. The problem is, most rye and pumpernickel (made primarily from rye) bread in this country is made with refined flours. Be persistent; look for “whole rye” topping the ingredients list to get the healthy benefits.

Buckwheat
This common pancake whole grain is one of the whole grains many people living with celiac disease can tolerate (others include quinoa, amaranth, and sorghum). And it’s one of the best grain-based sources of magnesium, a wonder mineral that does everything from ease PMS symptoms to improve nerve functioning, and manganese, which boosts brain power. And thank goodness for that, because who doesn’t enjoy a good buckwheat pancake from time to time!

 Whole-Wheat Couscous
Most of the couscous you see is a form of pasta, usually made from refined wheat flour. So when you’re eying the items in the aisle for the healthiest couscous pick, look for the whole-wheat kind, often most easily found in natural-food stores. Skipping the refined version and going with the whole-grain type will gain you 5 additional grams of fiber.

Corn
Yes, corn can be healthy for you when it’s whole! A good source of B vitamins, magnesium, and phosphorus, whole corn is also thought to increase healthy gut flora, which can ward off diabetes, heart disease, and chronic inflammation. Yellow corn is also high in antioxidants. The easiest way to eat whole corn? Popcorn! Just skip the microwavable kinds that use harmful chemicals in the bags’ nonstick lining. Instead, buy organic popcorn kernels and make microwave popcorn in an ordinary paper bag, or do it the old-fashioned way on the stovetop. Organic is important, as about 40 percent of the corn grown in the United States is genetically modified (GM) to withstand higher doses of pesticides. Some studies are starting to link GM foods to allergies and other health problems.

 Quinoa
Though it’s technically a seed and not a grain, this ancient South American power food is packed with more protein than any other grain, and each uncooked cup of the stuff (about three servings) has 522 milligrams of omega-3 fatty acids. Your family will likely enjoy its light, nutty flavor for a change of pace at the dinner table.

Freekeh
This Arabic grain is a low-carb form of ancient wheat that has up to four times more fiber than brown rice. Freekeh kernels are harvested while they’re young and then roasted. They contain more vitamins and minerals, such as immune-boosting selenium, than other grains. Once in your stomach, freekeh acts as a prebiotic, stimulating the growth of healthy bacteria that aid digestion. Look for it in Middle Eastern markets or natural-food stores.
