Health benefits
Green tea is particularly rich in health-promoting flavonoids (which account for 30% of the dry weight of a leaf), including catechins and their derivatives. The most abundant catechin in green tea is epigallocatechin-3-gallate (EGCG), which is thought to play a pivotal role in the green tea's anticancer and antioxidant effects. Catechins should be considered right alongside of the better-known antioxidants like vitamins E and C as potent free radical scavengers and health-supportive for this reason.
Most of the research showing the health benefits of green tea is based on the amount of green tea typically consumed in Asian countries—about 3 cups per day (which would provide 240-320 mg of polyphenols). Just one cup of green tea supplies 20-35 mg of EGCG, which has the highest antioxidant activity of all the green tea catechins.
The health benefits of green tea have been extensively researched and, as the scientific community's awareness of its potential benefits has increased, so have the number of new studies. As of November 2004, the PubMed database contained more than 1,000 studies on green tea, with more than 400 published in 2004!
Green tea drinkers appear to have lower risk for a wide range of diseases, from simple bacterial or viral infections to chronic degenerative conditions including cardiovascular disease, cancer, stroke, periodontal disease, and osteoporosis.

12 ways to keep your brain young
Every brain changes with age, and mental function changes along with it. Mental decline is common, and it’s one of the most feared consequences of aging. But cognitive impairment is not inevitable. Here are 12 ways you can help reduce your risk of age-related memory loss.1. Get mental stimulation
Through research with mice and humans, doctors suspect that brainy activities stimulate new connections between nerve cells and may even help the brain generate new cells, developing neurological “plasticity” and building up a functional reserve that provides a hedge against future cell loss.
Any mentally stimulating activity should help to build up your brain. Read, take courses, try “mental gymnastics,” such as word puzzles or math problems Experiment with things that require manual dexterity as well as mental effort, such as drawing, painting, and other crafts.
2. Get physical exercise
Research shows that using your muscles may also help your mind. Animals who exercise regularly increase the number of tiny blood vessels that bring oxygen-rich blood to the region of the brain that is responsible for thought. Exercise also spurs the development of new nerve cells and increases the connections between brain cells (synapses). This results in brains that are more efficient, plastic, and adaptive, which translates into better performance in aging animals. Exercise also lowers blood pressure, improves cholesterol levels, fights diabetes, and reduces mental stress, all of which can help your brain as well as your heart.

Healthier choices at fast food restaurants
When is it healthy to eat fast food?Rarely. Typically, fast food is low in nutrition and high in trans fat, saturated fat, sodium, and calories.
Making healthier choices at fast food restaurants is easier if you prepare ahead by checking guides that show you the nutritional content of meal choices at your favorite restaurants. Free downloadable guides help you evaluate your options. If you have a special dietary concern, such as diabetes, heart health or weight loss, the websites of national non-profits provide useful advice. You can also choose to patronize restaurants that focus on natural, high quality food.
If you don’t prepare ahead of time, common sense guidelines help to make your meal healthier. For example, a seemingly healthy salad can be a diet minefield when smothered in high-fat dressing and fried toppings, so choose a salad with fresh veggies, grilled toppings and a lighter dressing. Portion control is also important, as many fast food restaurants serve enough food for several meals in the guise of a single serving.
Tips for making healthy choices at fast food restaurants
Make careful menu selections – pay attention to the descriptions on the menu. Dishes labeled deep-fried, pan-fried, basted, batter-dipped, breaded, creamy, crispy, scalloped, Alfredo, au gratin or in cream sauce are usually high in calories, unhealthy fats or sodium. Order items with more vegetables and choose leaner meats.
Drink water with your meal. Soda is a huge source of hidden calories. One 32-oz Big Gulp with regular cola packs about 425 calories, so one Big Gulp can quickly gulp up a big portion of your daily calorie intake. Try adding a little lemon to your water or ordering unsweetened iced tea.
“Undress” your food. When choosing items, be aware of calorie- and fat-packed salad dressings, spreads, cheese, sour cream, etc. For example, ask for a grilled chicken sandwich without the mayonnaise. You can ask for a packet of ketchup or mustard and add it yourself, controlling how much you put on your sandwich.
Special order. Many menu items would be healthy if it weren't for the way they were prepared. Ask for your vegetables and main dishes to be served without the sauces. Ask for olive oil and vinegar for your salads or order the dressing "on the side" and spoon only a small amount on at a time. If your food is fried or cooked in oil or butter, ask to have it broiled or steamed.
Eat mindfully. Pay attention to what you eat and savor each bite. Chew your food more thoroughly and avoid eating on the run. Being mindful also means stopping before you are full. It takes time for our bodies to register that we have eaten. Mindful eating relaxes you, so you digest better, and makes you feel more satisfied.
Avoid Supersized portions - An average fast food meal can run to 1000 calories or more, so choose a smaller portion size, order a side salad instead of fries, and don't supersize anything. At a typical restaurant, a single serving provides enough for two meals. Take half home or divide the portion with a dining partner.
Avoid Salt. Fast food restaurant food tends to be very high in sodium, a major contributor to high blood pressure. Don’t add insult to injury by adding more salt.
Avoid Bacon. It’s always tempting to add bacon to sandwiches and salads for extra flavor, but bacon has very few nutrients and is high in fat and calories. Instead, try ordering extra pickles, onions, lettuce, tomatoes or mustard to add flavor without the fat.
Avoid Buffets – even seemingly healthy ones like salad bars. You'll likely overeat to get your money's worth. If you do choose buffet dining, opt for fresh fruits, salads with olive oil & vinegar or low-fat dressings, broiled entrees and steamed vegetables. Resist the temptation to go for seconds, or wait at least 20 minutes after eating to make sure you're really still hungry before going back for more.

Beets : from A to Z
Beets or beetroots, as they are called, belong to the Chenopodiaceous family. Health benefits of beet roots can be attributed to their richness in nutrients, vitamins and minerals. They are a source of carotenoids and lutein/zeaxanthin. Beets are also rich in dietary fiber, vitamin C, magnesium, iron, copper and phosphorus. Beet is a source of beneficial flavonoids called anthycyanins. They are very low in calories but have the highest sugar content of all vegetables. It is also used to make refined sugar.Health Benefits of Beet
1. Good for heart: Beet fiber helps to reduce cholesterol and triglycerides by increasing the level of HDL. High level of triglycerides increases the risk for heart related problems. The presence of the nutrient betaine lowers the levels of homocysteine in the body which can be harmful to the blood vessels. Thus, consumption of beetroot helps to prevent cardiovascular diseases.
Did you hear anything about medlar (Mespilus germanica)?
The brown pear and appleshaped fruits are subglobose or pyriform and crowned by foliaceous sepals (drupes 5). The fruit ranges in diameter from 1.5 to 3 cm and weight from very small (about 10 g) to big (more than 80 g). The plant is native in Europe and Asia. Its fruit is well known for its nutritive value especially by the people of Southeastern Europe, Turkey and Iran . The pomelike fruit originates from the inferior ovary, generally with five stony seeds. The skin color is brown, sometimes tinged reddish. The harvest of fruit bletted on the plant in late autumn or the harvest of fruits at physiological ripening and their storage in straw until over-ripening are well known traditions. The medlar is a typical climacteric fruit which has gained value in human consumption and commercial importance in recent years, attracting researches to study its chemical or nutritional compositions . Medlar fruit is widely consumed in some countries such as Turkey a unique place where the people grow the wild and alternative cultivars for the consumption of the fruits in different ways. A long list of recipes utilizing medlar fruits such as in jams and jellies are well known . The astringency of the fruit is well known and it has been reported that bletted pulp or syrup of the fruit is a popular remedy against enteritis and has many human healing properties . The bletted fruits have a sweet and slightly acidic flesh; jams and jellies can be obtained. In cookery, a surprisingly long list of recipes can be found. The astringency of the fruits has been well known since ancient times. The fruit of medlars are used as a nutritional material by the local customer and are consumed by the local people as marmalade. The medlar fruit is also used as treatment of constipation, diuretic, and to rid the kidney and bladder of stones . The fruit is consumed as a medicinal remedy in Turkey. In 1964, two new antibiotic cyclopentoid monoterpenes were isolated and identified. These are genipic acid and genipinic acid, which are its carbomethoxyl derivative . Recently, the physical, physicochemical and chemical changes during maturation of Spanish medlar have been reported and flavanols in medlar fruit have been analyzed. More recently, changes in mineral composition at different stages of maturity of medlar , fatty acid composition during ripening of medlar , fatty acid composition during development and maturation of medlar fruit , volatile components of its seeds and polyphenoloxidase from medlar fruits have been reported. Besides these studies, data on the nutritional value of medlars are still scarce.
Everything about honey
This wonderfully rich golden liquid is the miraculous product of honey bees and a naturally delicious alternative to white sugar. Although it is available throughout the year, it is an exceptional treat in the summer and fall when it has just been harvested and is at its freshest.
The fascinating process of making honey begins when the bees feast on flowers, collecting the flower nectar in their mouths. This nectar then mixes with special enzymes in the bees' saliva, an alchemical process that turns it into honey. The bees carry the honey back to the hive where they deposit it into the cells of the hive's walls. The fluttering of their wings provides the necessary ventilation to reduce the moisture's content making it ready for consumption.
