Enjoy The Rainbow - The Color Wheel Of Fruits And Vegetables

Saturday, August 25th, 2007
Darrell Miller asked:


The majority of people know that eating five servings of fruits and vegetables a day is very important. Also, by eating fruits and vegetables of a variety of different colors, one can get the best all-around health benefits. Each different color fruit and vegetables contains unique health components that are essential to our health. Fruits and vegetables are very important to our health because they are whole foods, created by nature, that are rich in a large amount of nutrients. The processed foods that we so commonly eat, can never compare to the health benefits provided by strawberries or broccoli, which have fiber, vitamins, and enzymes built right in. The phrase “eating a rainbow” of fruits and vegetables is a simple way of remembering to get as much color variety in your diet as possible, so that you can maximize your intake of a broad range of nutrients. The colors of fruits and vegetables are a small clue as to what vitamins and nutrients are included. By getting a variety of different colored fruits and vegetables, you are guaranteed a diverse amount of essential vitamins and minerals.

When eating red fruits and vegetables including tomatoes, berries, peppers, and radishes, you take in nutrients such as lycopene, ellagic acid, Quercetin, and Hesperidin, to name a few. These nutrients reduce the risk of prostate cancer, lower blood pressure, reduce tumor growth and LDL cholesterol levels, scavenge harmful free-radicals, and support join tissue in arthritis cases. Carrots, Yams, Squash, Papayas, and other orange and yellow fruits and vegetables contain beta-carotene, zeaxanthin, flavonoids, lycopene, potassium, and vitamin C. These nutrients reduce age-related macula degeneration and the risk of prostate cancer, lower LDL cholesterol and blood pressure, promote collagen formation and healthy joints, fight harmful free radicals, encourage alkaline balance, and work with magnesium and calcium to build healthy bones. White fruits and vegetables, including mushrooms, white tea, flaxseed, and pumpkin, contain nutrients such as beta-glucans, EGCG, SDG, and lignans that provide powerful immune boosting activity. These nutrients also activate natural killer B and T cells, reduce the risk of colon, breast, and prostate cancers, and balance hormone levels, reducing the risk of hormone-related cancers. Wheat grass, barley grass, oat grass, kale, spinach, cabbage, alfalfa sprouts, mustard greens, and collard greens are all examples of green vegetables that contain chlorophyll, fiber, lutein, zeaxanthin, calcium, folate, vitamin C, calcium, and Beta-carotene. The nutrients found in these vegetables reduce cancer risks, lower blood pressure and LDL cholesterol levels, normalize digestion time, support retinal health and vision, fight harmful free-radicals, and boost immune system activity. Blue and purple fruits and vegetables such as blueberries, pomegranates, grapes, elderberries, eggplant, and prunes contain nutrients which include lutein, zeaxanthin, resveratrol, vitamin C, fiber, flavonoids, ellagic acid, and quercetin. Similar to the previous nutrients, these nutrients support retinal health, lower LDL cholesterol, boost immune system activity, support healthy digestion, improve calcium and other mineral absorption, fight inflammation, reduce tumor growth, act as an anticarcinogens in the digestive tract, and limit the activity of cancer cells.

These nutrients that are found in the above-listed fruits and vegetables can have a significant impact on our health. Quercetin, which is found in apples, onions and other citrus fruits, not only prevents LDL cholesterol oxidation, but also helps the body cope with allergens and other lung and breathing problems. Ellagic acid, which is mainly found in raspberries, strawberries, pomegranates, and walnuts, has been proven in many clinical studies to act as an antioxidant and anticarcinogens in the gastrointestinal tract. This nutrient also has been proven to have an anti-proliferative effect on cancer cells, because it decreases their ATP production. The best-known of the carotenoids, beta-carotene, is converted into vitamin A upon entering the liver. Although being known for its positive effects on eyesight, it has also been proven to decrease cholesterol levels in the liver. Clinical studies have proven that lycopene, mainly found in tomatoes, may decrease the risk of prostate cancer, as well as protect against heart disease. Lutein, which is found in blueberries and members of the squash family, is important for healthy eyes. However, it does support your heart too, helping to prevent against coronary artery disease.

Along with the above stated nutrients, there are even more nutrients found in fruits and vegetables that provide a great deal of support to our body. Almost everyone has heard of vitamin C, which keeps our immune system strong; speeds wound healing, and promote strong muscles and joints. This nutrient is scattered throughout the spectrum of fruits, but commonly associated with oranges and other citrus fruits. Potassium, which is the nutrient most Americans are deficient in, does great things for our hearts, and lowers blood pressure. Another good food component many people don’t get enough of if fiber, found in fruits, vegetables, and whole grains. Flavonoids, which include anthocyanins, flavones, isoflavones, proantocyanidins, quercetin and more, are found almost everywhere. They are responsible for the colors in the skins of fruits and vegetables and help to stop the growth of tumor cells and potent antioxidants. They also can reduce inflammation. Beta-glucan, found in mushrooms, stabilizes and balances the body’s immune system by supporting white blood cells. EGCG is found in tea and has been shown to reduce the risk of colon and breast cancer. It boosts the immune system and encourages T-cell formation, which defends our body against sickness and disease. Lastly, bioflavonoids, which are found in citrus fruits, are considered a companion to vitamin C because they extend the value of it in the body. These nutrients have the capabilities to lower cholesterol levels and support joint collagen in arthritis cases.

The number one excuse for not eating the required five servings of fruits and vegetables each day is they are too expensive. However, as compared to the amount of money spent on prepackaged, processed, and fast foods, most fruits and vegetables (with the exception of those that are not in season) are not all that expensive. Because frozen fruits and vegetables retain the majority of their nutritional value, they can be an excellent alternative when certain foods are out of season. Someone who is not able to eat five servings of fruits and vegetables each day can also drink fruit and vegetable drinks in their place. Although this shouldn’t become a habit, fruit and vegetable drink mixes can be an excellent substitute when you’re rushed or traveling. The need for fruits and vegetables in our diet is growing rapidly with the type 2 diabetes, heart disease, and high cholesterol, hypertension that result from the “Typical American Diet” of fatty meats, processed sugars, and refined grains. Great fruit drink Mixes and vegetable mixes can be found at your local health food store or internet health food store.

10 Steps to Remember When Eating at a Chinese Restaurant

Monday, August 6th, 2007
Emilia Klapp, R.D., B.S. asked:


10 Steps to Remember When Eating at a Chinese Restaurant

 

Introduction

Chinese food appeals to many of us because it is tasty and relatively inexpensive. We are also under the impression that Chinese cuisine is healthy as it includes large portions of vegetables and low amounts of fat. That’s true when the dishes are prepared the traditional Chinese way in China. But American-Chinese restaurants have modified their food for American tastes and as a result, it is not as healthy as the traditional one. Western Chinese restaurants offer appetizers, fried rice, meat rolled in butter, and sweet sauces among their “goodies”. And to top it all, the portions are much larger than the ones served in mainland China. That’s why, having all this in mind, if you want to eat healthy at a Chinese restaurant, you have to choose wisely.

 

1. Start by choosing a good restaurant

When you are in the mood for Chinese food, avoid the typical Chinese restaurant where you can eat as much as you want for a fix price. Chances are you may not want to leave the restaurant until you feel you got your money’s worth. Unfortunately, if you do so, the restaurant will get your money but you will get the calories. Not a win-win situation. Instead, go to a restaurant where the waiter takes your order.

 

2. Start with a soup

A smart move when eating at a Chinese restaurant is to order a soup. Two advantages: first, less overall fat in your meal and second, the soup broth will fill you up. This translates into eating less when the waiter brings the main course.

 

By starting your meal with an appetizer you may ruin your goal of calories, carbohydrates, fat, etc. Pork ribs, egg rolls, fried wonton and any other fried foods are high in fat, sugar, and calories. If the waitress brings Chinese fried noodles to keep you busy until the food is served, put them aside or ask her to remove them from the table. Instead, you can kill time while you wait for the food by drinking Chinese tea. No calories there unless you add sugar.

 

3. Choosing the main course

When choosing the main course look for dishes that are abundant in vegetables and have small portions of meat. You can reduce calories by choosing seafood or chicken instead of choosing beef, pork, lamb or duck.  You can also order two dishes: one that has meat as the base and one that is mainly vegetables such as green beans or spinach and mix them.

 

4. Avoid fatty dishes

Read the menu carefully and avoid for the fattiest dishes. Some words will give you a clue: beef rolled in butter or breadcrumbs, crunchy pork, etc. Find out if the meat was fried before being sauté with the vegetables. If that is the case, ask if they can sauté the meat you have chosen instead of frying it.

 

5. Watch out for hidden carbohydrates

Sweet and sour sauces as well as other typical sauces of the Chinese cuisine are full of carbohydrates and if you are diabetic, they can raise your blood sugar. Sugar and starches keep adding carbohydrates to many main dishes. You will also find carbohydrates in the corn flour used to thicken sauces and in the ingredients used to marinate the meat. Read the small print and ask a lot of questions to the waiter.

 

6. Be careful with the rice

You know that at a Chinese restaurant, you are going to be served a big bowl of rice and as you may be aware, rice contains many carbohydrates. Avoid fried rice and regular soy sauce to flavor it; you will end up with a lot of fat and sodium in your meal. If possible ask for brown rice which is rich in fiber. If they don’t have it available, hold the rice. Remember that a cup of rice has at least 45 grams of carbohydrate.

 

7. Reduce the salt

Order dishes with light sauces, not too thick. If you need soy sauce ask for the low sodium version and mix it with steamed brown rice, not with fried rice. To add flavor to your meal you can add some hot sauce; it has less sodium and less calories.

 

8. Share the dishes

If you have company, order one main dish, a soup or aperitif and some rice. Then, share it.

 

9. Eat with chopsticks

Eat your meal with chopsticks. If you are as skilful with them as I am, they may slow you down. But don’t worry because as everything in life, it has a positive side: you will probably eat less. Don’t fall into the temptation of asking for a fork and a knife; you may regret it.

 

10. And for dessert…

As for dessert, order fruit and never mind the ice-cream with sugared walnuts which I know by experience it is hard to resist. But if you have followed the above recommendations, you will feel pretty good about having eaten a healthy meal. So, why ruining it?

Eating Properly For Your Teeth

Thursday, August 2nd, 2007
Cathy Warschaw asked:


Preventing cavities is not just about good dental hygiene; it also is about what you eat and when you eat it. When you eat during meals the food does not stay on your teeth as long as when you eat in between meals. So if you have to have a sweet, it is better to have it with your meal than in between meals. Most people brush only after meals. Since it only takes about 20 minutes for plague to start forming on your teeth and to begin to damage enamel if you eat between meals and do not brush until after the next meal a lot of time will have passed from the time you eat your snack to the time you next brush your teeth.

All carbohydrates break down into simple sugars and the process starts in your mouth. Bacteria on your teeth that live in your mouth use the sugars from these foods to produce acids. It is these acids that can cause tooth decay. The longer the food remains on the teeth, the more acid is produced. Removing the food particles takes the simple sugars out of the acid equation. People who drink sweetened coffee or other sugary beverages throughout the day keep a steady supply of sugar on their teeth for the bacteria to cling to.

Certain foods help to increase the amount of saliva in your mouth and saliva helps to wash away bacteria. Some food like aged cheese helps to buffer the acid and this helps to prevent cavities if eaten at the end of a meal. Your mouth depends on good nutrition to stay healthy.

For overall good health for your body and your mouth it is important to follow the guidelines set by the U.S. Department of Agriculture and the Department of Health and Human Services, which basically says:

Eat whole grains daily, such as brown rice, oatmeal and whole wheat bread instead of refined grains, such as white bread and white rice.

Eat healthier vegetables, including dark green and orange vegetables.

Eat a variety of fruits.

Choose a diet with plenty of grain products, fruits and vegetables.

Choose fish, beans, nuts and seeds for some of your protein needs.

Choose beverages and foods to moderate your intake of sugars.

Choose and prepare foods with less salt.

If you drink alcoholic beverages, do so in moderation.

Aim for a healthy weight and be physically active each day.

There is a new interactive guide that the USDA has devised to help people understand these guidelines that can be found at www.mypyramid.gov.

These guidelines when followed will keep your body healthy which in turn helps to keep your mouth healthy. It is important to remember these guidelines and to choose your food carefully. Watch out for eating between meals and if you do so, please remember to chew sugarless gum or to rinse your mouth with water to help remove some of the food particles and sugar. The connection between the food that you eat and the health of your teeth and gums is amazingly close. You need healthy teeth to enjoy food and you need healthy food choices to protect your teeth.
