Fruits and Vegetables That HealCornLower cholesterol, Boost energy levels
Corn contains a type of dietary fiber called soluble fiber. When you eat corn, this fiber binds with bile, a cholesterol-laden digestive fluid produced by the liver. Since soluble fiber isnít readily absorbed by the body, it passes out of the body, taking cholesterol with it.
We all heard a lot about how oat and wheat bran can lower cholesterol. Corn bran is in the same league. In a study at Illinois State University in Normal, researchers put 290 men with high cholesterol on low-fat diets. After two weeks on the diet, some of the men were each given 20 grams ( almost Ĺ tablespoon) of corn bran a day, while others received similar amount of wheat bran. During the six-week study, those on the corn bran plan had a drop in cholesterol of more than 5 % and about a 13% drop in triglycerides, blood fats that in large amounts can contribute to heart disease. Those who were given wheat bran showed no change beyond the initial drop caused by being on a low-fat diet.
The beauty of corn is that it provides a lot of energy while delivering a small amount of calories. Corn is an excellent source of thiamin, a B vitamin thatís essential for converting food to energy. An ear of corn provides 0.2 milligram of thiamin, 13 % of Daily Value.
And since fresh sweet corn consists primarily of simple and complex carbohydrates, itís a superb energy source. It fulfills our energy needs without providing us with substantial amount of fat. What little fats there are in corn are the polyunsaturated and monounsaturated kinds, which are far healthier than the saturated fats.
Not all corn is created equal. Whereas yellow corn has more than 2 grams of fiber per serving, white corn more than doubles that, with a bit more than 4 grams per ear. When you buy corn, look for ears that have full, plump kernels and purchase it at the optimum stage of maturity. Under those conditions, the level of nutrients is higher.

Re: Fruits That HealLemons and Limes
Heal cuts and bruises, Prevent cancer and heart disease
You may not like tartness of lemons and limes, but back in the nineteen century people literally craved them, not for the tart taste but for remarkable health benefits these colorful fruits contain.
British sailors, for example, who typically spent months at sea without fresh fruits or vegetables, would drink lime juice to prevent scurvy, a terrible disease caused by vitamin C deficiency. And in California during the Gold Rush, when fruits were equally scarce, miners paid top dollar for lemons.
Of all nutrients we’re most familiar with, vitamin C is perhaps the most impressive. During cold season it’s always in demand, since it lowers levels if histamine, a naturally occurring chemical that can cause red eyes and runny noses. Vitamin C is also a powerful antioxidant, meaning that it helps disarm powerful oxygen molecules in the body that contribute to cancer and heart disease. The body also uses vitamin C to manufacture collagen, the staff that glues cells together and is needed to help heal cuts and wounds.
The pulp and juice from lemons and limes are rich sources of vitamin C. A large lemon, for example contains about 45 milligrams of vitamin C, limes are also good, with s small lime containing about 20 milligrams of vitamin C.
There is more to lemons and limes than just vitamin C. These citrus fruits also contain additional compounds such as limonin and limonene, which help to block some of the cellular changes that can lead to cancer.
Limonene, which is found mainly in the colorful skin, or zest, of the fruit, has been shown to increase the activity of proteins that help eliminate estradiol, a naturally occurring hormone that has been linked with breast cancer. Limonene has also been shown to increase the level of enzymes in the liver that can remove cancer-causing chemicals.
Some innovative organic food companies add citrus zest to baking flower to provide added health benefits.
Whether you’re making a lemon meringue pie or simply adding flavor to store-bought lemon yogurt, be sure to add plenty of zest. The healing compound limonene makes up about 65% of oils in the peel. While fresh citrus peel contains the most healing compounds, dried lemon peel isn’t bad and you can find dried lemon peel in the spice rack at the supermarket.

Re: Fruits That HealAvocado
Control cholesterol, Lower blood pressure, Prevent birth defects
Avocado has more calories than almost any fruit on the planet – 731! Its also has the dubious distinction of being one of the few fruits with a measurable fat content, with up to 30 grams each. That’s the daily recommended amount for an average adult.
You wouldn’t think that a food that’s so fattening could be good for you. But the word from dietitians, who say that adding a little avocado to your diet every day could actually improve your health.
Avocados are great source of folate and potassium. They also contain high amount of fiber and monounsaturated fat, both of which are good news for people who are concerned with diabetes or heart health.
People with diabetes have traditionally been told to eat more carbohydrates and cut back on fat. Overall that’s good advice, but it’s not necessarily the best advice for everyone.
Doctors have discovered that when some people who have diabetes eat a lot of carbohydrates, they tend to develop high levels of triglycerides, a type of blood fat that may contribute to heart disease. Surprisingly, when people replace some of those carbohydrates with fat, particularly the kind of fat found in avocados, the dangerous fats in the bloodstream tend to decline.
Avocados are rich source of monounsaturated fats, particularly a kind called oleic acid, and these monounsaturated fats improve fat levels in the body and help control diabetes.
In one study, scientists put 160 women with diabetes on a relatively high-fat diet, with about 40% of calories coming from fat. Most of the fat came from avocados. The result was a 20% drop in triglycerides. Women on a higher-carbohydrate plan, by contrast, had only 7% drop in triglycerides.
What’s nice about avocados is that they provide a lot of these monounsaturated fats. Someone on a 2,000-calorie-a-day diet, for example, might be advised to eat 33 grams of monounsaturated fat. You can get about 20 grams from just one avocado.
People with diabetes aren’t the only ones who benefit from eating a little more avocados. The oleic acid in avocados can also help people lower their cholesterol.
In a small study from Mexico, where guacamole is considered almost a food group, researchers compared the effects of two low-fat diets. The diets were the same except that one included avocados. While both lowered levels of dangerous, low-density lipoprotein cholesterol, the avocado diet raised levels of healthful high-density lipoprotein cholesterol while lowering triglycerides.
Avocados have large levels of potassium, half of avocado provides 548 milligrams of potassium, 16% of the Daily Value. That’s 15% more than you’d get in a medium banana. You can never get too much potassium – even small additions can make bid difference to your hearth’s health.
Avocados one of the perfect foods when you’re eating for two, particularly when it comes to getting enough folate, a nutrient that helps prevent life-threatening birth defects of the brain and spine. Many women don’t get enough folate in their diets, but avocados can go a long way towards fixing that. Half an avocado contains 57 milligrams of folate, 14% of the Daily Value.
Moms-to-be aren’t the only ones who should be dipping their chips in guacamole, though. Everyone needs folate. Its’ an essential nutrient for keeping nerves functioning properly. It also help fight hearth disease.

Re: Fruits That HealParsnips
Prevent colon cancer, Lower the risk of heart disease, Stabilize blood sugar levels, Decrease the risk of stoke
Parsnips are strong-testing, oddly sweet vegetables that don’t usually win any awards for Best-Looking Vegetable in Show. They look like carrots that have seen a ghost.
But despite parsnips’ strong flavor and pale appearance, their nutritional profile is quite attractive. A member of the parsley family, parsnips are good sources of folate, fiber, and phenolic acids, which have been shown in studies to help block cancer.
Dietary fiber is on the top of all healing substances and parsnips are an excellent source. A little more than half of the fiber in parsnips is the soluble kind, which means that it becomes gel-like in the digestive system. This helps block the intestine from absorbing fats and cholesterol from foods. At the same time, it dilutes bile acids in the intestine, which can prevent them from causing cancer.
Soluble fiber has shown impressive ability to relieve or prevent many other conditions as well. Researchers have found that getting enough of soluble fiber in the diet can prevent many intestinal conditions and also can curb the blood sugar swings that occur with diabetes.
Some nutrition experts say that too little folate is our number one nutritional deficiency, particularly among younger folks, who often eat large amounts of fast food that largely devoid of vitamins. Parsnips are a good source of folate, with 1 cup containing 91 milligrams, 23% of DV.
Getting enough folate has been shown to prevent certain birth defects. It’s also strongly suspected of reducing the risk of stroke. Folate decreases blood levels of homocysteine, a chemical that may jam the arteries and stop blood flow.
Obviously, unless you truly have a passion for parsnips, it’s unlikely that you’ll ever eat three or more servings a day. But eating jus a half-cup will provide not only fiber and folate but also 280 milligrams of potassium, this will go a long way toward keeping your arteries clear.
Along with carrots and celery, parsnips are members of the umbelliferae family. Foods in this family contain a number of natural compounds called phytonutrients, which have been shown in many studies to block the spread of cancer cells. Chief among these compounds called phenolic acids. What phenolic acids do is attach themselves to potential cancer-causing agents in the body, creating bigger molecule – so big that the body can’t absorb it.
Research has shown that members of umbelliferae family can also fight cancer by inhibiting tumor growth.
Before storing parsnips in the refrigerator, snip the greens from the top, otherwise, the greens will draw moisture and nutrients from the root itself.
Some of the nutrients in parsnips are water-soluble and are quickly lost during cooking. Its better to cook them unpeeled. Once they tender, let them cook, then scrap or peel the skin away.

Re: Fruits and Vegetables That HealTangerinesTangerines are a type of Mandarin orange that were first cultivated in China and Japan. The name 'tangerine' refers to Tangier, Morrocco because that's the route by which they were first brought to Europe.
Prevent heart disease, Reduce the risk of cancer
At some time in the past, youíve probably used canned mandarin oranges Ė tiny sections of orange fruit that look precious and perfect. Mandarin oranges are really small tangerines, or to be more precise, tangerines are really mandarin oranges, since tangerine isnít a formal botanical term. So mandarin oranges Ė Iíll still call them tangerines Ė are actually not that exotic.
But their benefits are anything but commonplace. Tangerines contain quite a large amount of healing compounds. Like oranges, they are rich in vitamin C. One tangerine has 26 milligrams, 43% of Daily Value (DV). Tangerines also contain compound called beta-cryptoxanthin, which turns into vitamin A in the body. Eight ounces of tangerine juice can provide up to 1,037 international units of vitamin A, more than 20% of the DV.
This combination is important, since both vitamins are antioxidants Ė they can help stop harmful oxygen molecules called free radicals from causing cell damage in the body that can lead to everything from wrinkles and heart disease to cancer.
What makes tangerines really exciting to researchers are two compounds, tangeretin and nobiletin, which appear to be extremely potent against certain types of breast cancer. Researchers at the University of Western Ontario in London, Canada, found that each of these compounds was 250 times more potent against one type of human breast cancer cell than genistein, a powerful anti-cancer compound found in soy. When these compounds were combined, they were even more powerful, the researchers found.
Recently, in Japan, researchers at the Tokyo College of Pharmacy found that tangeretin could inhibit the growth of leukemia cells, essentially by causing them to program their own deaths. They also found the compound wasnít toxic to healthy cells, which is an important goal for any cancer treatment. We need more research into healing power and benefits of Tangerines and no doubt, we will see more research done in the near future.
While the flesh of tangerines contains great share of healing compounds, most of the tangeretin and nobiletin are concentrated in the rind. To add more of these to your diet, use zester to remove strips of the outer rind, then stir them into glass of juice, mix them into rice and pasta dishes, or sprinkle them on salads. You will get extra-zingy flavor along with extra benefits.

Re: Fruits and Vegetables That HealRaisins
Improve digestion, Lower blood pressure, Keep blood healthy
Raisins may not be much to look at, but they do have quite a history.
Prehistoric cave dwellers attributed religious powers to them. They made raisin necklaces and decorations and drew pictures of raisins on cave walls. As early as 1000 B.C., the Israelites used them to pay taxes!
These days raisins occupy a much humbler place in society, but they just as useful as ever. Backpackers and hikers appreciate raisins for being high-energy, low-fat, very convenient snack. They fit easily in a lunch box, they almost never go bad, even if they’re in a pantry for a long time.
Raisins offer more than just convenience. Recent studies suggest that they can help lower blood pressure and cholesterol and even play a role in keeping digestion and blood healthy.
If you have high blood pressure – or even if you don’t, but you want to make sure your pressure stays in a healthy range- raisins are one of the best snacks you can buy. They are good source of potassium, a mineral that has been shown to lower high blood pressure.
In one study, researchers at John Hopkins Medical Institution in Baltimore gave men either potassium supplements or blank pills. Those who were given potassium saw their systolic pressure (the higher number) drop 7 points, while their diastolic pressure went down 3 points. Just ľ cup of raisins contains 272 milligrams of potassium, 10% of the Daily Value. The researchers concluded that people, especially over the age of 40, ought to be consuming a fair amount of foods, such as raisins that contain high levels of potassium.
When we think of iron-rich foods, things such as red meat and liver usually come to mind. But raisins may be a better source of iron, particularly for people who eat little or no meat. Iron is essential for the creation of hemoglobin in red blood cells, which the body uses to transport oxygen. A quarter-cup of raisins has 0.8 milligram of iron, which is more than 8% of the Recommended Dietary Allowance (RDA) for men and 5% of the RDA for women.
Like other dried fruits, raisins also a good source of dietary fiber, with nearly 2 grams of fiber in ľ cup. Not only does fiber play role in helping to prevent everyday problems such as constipation but its also lowers cholesterol and risk of heart disease.
Few years ago, researchers at the Health Research and Studies Centre in Los Altos, California, asked people with high cholesterol levels to eat 3 ounces of raisins (a little more than a half-cup) a day as part of a high-fiber, low-fat diet. After a month, the participant’s total cholesterol dropped an average of more than 8 percent, while their harmful low-density lipoprotein cholesterol levels dropped 15%.
There is very little nutritional difference between black and golden raisins. The black variety has more thiamin, while the golden seedless type has a bit more vitamin B6. The main difference between them is the way they are dried.
Black, or sun-dried raisins are actually dried in the sun. This is what gives them their dark, shriveled look.
Golden seedless raisins are dried by exposing them to the fumes of burning sulfur in a closed chamber, which gives them their golden hue. In mid-1980’s researchers discovered that some people are sensitive to sulfites compounds and can get an allergic-type reactions when exposed to them If you are sulfite-sensitive, you should stay clear of golden seedless raisins and favor sun-dried varieties.
Raisins contain a type of iron called nonheme iron, which is harder for the body to absorb than the heme iron found in meats. Eating raisins along with foods high in vitamin C, however, will help improve absorption of nonheme iron.
To get the most raisins in your diet, it is often recommended buying snack-size packs. Due to their small size and the fact that raisins almost never go bad, they’re perfect for keeping them in your purse, glove compartment, or desk drawer and eating whenever you are in the mood for a quick snack.
