.Some cholesterol-lowering foods deliver a good dose of soluble fiber, which binds cholesterol and its precursors in the digestive system and drags them out of the body before they get into circulation. Others provide polyunsaturated fats, which directly lower LDL, or “bad” cholesterol. And those with plant sterols and stanols keep the body from absorbing cholesterol. Here are 5 of those foods:
Oats.An easy way to start lowering cholesterol is to choose oatmeal or an oat-based cold cereal like Cheerios for breakfast. It gives you 1 to 2 grams of soluble fiber. Add a banana or some strawberries for another half-gram.
Beans.Beans are especially rich in soluble fiber. They also take a while for the body to digest, meaning you feel full for longer after a meal. That’s one reason beans are a useful food for folks trying to lose weight. With so many choices — from navy and kidney beans to lentils, garbanzos, black-eyed peas, and beyond — and so many ways to prepare them, beans are a very versatile food.
Nuts.A bushel of studies shows that eating almonds, walnuts, peanuts, and other nuts is good for the heart. Eating 2 ounces of nuts a day can slightly lower LDL, on the order of 5%. Nuts have additional nutrients that protect the heart in other ways.
Foods fortified with sterols and stanols: Sterols and stanols extracted from plants gum up the body’s ability to absorb cholesterol from food. Companies are now adding them to a wide variety of foods. They’re also available as supplements. Getting 2 grams of plant sterols or stanols a day can lower LDL cholesterol by about 10%.
Fatty fish.Eating fish two or three times a week can lower LDL in two ways: by replacing meat, which has LDL-boosting saturated fats, and by delivering LDL-lowering omega-3 fats. Omega-3s reduce triglycerides in the bloodstream and also protect the heart by helping prevent the onset of abnormal heart rhythms.
The glycemic index or glycaemic index (GI) is a number associated with a particular type of food that indicates the food’s effect on a person’s blood glucose (also called blood sugar) level. The number typically ranges between 50 and 100, where 100 represents the standard, an equivalent amount of pure glucose.
The GI represents the total rise in a person’s blood sugar level following consumption of the food; it may or may not represent the rapidity of the rise in blood sugar. The steepness of the rise can be influenced by a number of other factors, such as the quantity of fat eaten with the food. The GI is useful for understanding how the body breaks down carbohydrates and only takes into account the available carbohydrate (total carbohydrate minus fiber) in a food. Although the food may contain fats and other components that contribute to the total rise in blood sugar, these effects are not reflected in the GI.
The glycemic index is usually applied in the context of the quantity of the food and the amount of carbohydrate in the food that is actually consumed. A related measure, the glycemic load (GL), factors this in by multiplying the glycemic index of the food in question by the carbohydrate content of the actual serving. Watermelon has a high glycemic index, but a low glycemic load for the quantity typically consumed. Fructose, by contrast, has a low glycemic index, but can have a high glycemic load if a large quantity is consumed.
GI tables are available that list many types of foods and their GIs. Some tables also include the serving size and the glycemic load of the food per serving.
A practical limitation of the glycemic index is that it does not measure insulin production due to rises in blood sugar. As a result, two foods could have the same glycemic index, but produce different amounts of insulin. Likewise, two foods could have the same glycemic load, but cause different insulin responses. Furthermore, both the glycemic index and glycemic load measurements are defined by the carbohydrate content of food. For example when eating steak, which has no carbohydrate content but provides a high protein intake, up to 50% of that protein can be converted to glucose when there is little to no carbohydrate consumed with it. But because it contains no carbohydrate itself, steak cannot have a glycemic index. For some food comparisons, the “insulin index” may be more useful.
CLICK & SEE
Glycemic index charts often give only one value per food, but variations are possible due to variety, ripeness (riper fruits contain more sugars increasing GI), cooking methods (the more cooked, or over cooked, a food the more its cellular structure is broken with a tendency for it to digest quickly and raise GI more), processing (e.g., flour has a higher GI than the whole grain from which it is ground as grinding breaks the grain’s protective layers) and the length of storage. Potatoes are a notable example, ranging from moderate to very high GI even within the same variety.
The glycemic response is different from one person to another, and also in the same person from day to day, depending on blood glucose levels, insulin resistance, and other factors.
Most of the values on the glycemic index do not show the impact on glucose levels after two hours. Some people with diabetes may have elevated levels after four hours.
Why GI is so Important?
Over the past 15 years, low-GI diets have been associated with decreased risk of cardiovascular disease, type 2 diabetes, metabolic syndrome, stroke, depression, chronic kidney disease, formation of gall stones, neural tube defects, formation of uterine fibroids, and cancers of the breast, colon, prostate, and pancreas. Taking advantage of these potential health benefits can be as simple as sticking with whole, natural foods that are either low or very low in their GI value.
Determination of GI of a food:
Foods with carbohydrates that break down quickly during digestion and release glucose rapidly into the bloodstream tend to have a high GI; foods with carbohydrates that break down more slowly, releasing glucose more gradually into the bloodstream, tend to have a low GI. The concept was developed by Dr. David J. Jenkins and colleagues in 1980–1981 at the University of Toronto in their research to find out which foods were best for people with diabetes. A lower glycemic index suggests slower rates of digestion and absorption of the foods’ carbohydrates and may also indicate greater extraction from the liver and periphery of the products of carbohydrate digestion. A lower glycemic response usually equates to a lower insulin demand but not always, and may improve long-term blood glucose control and blood lipids. The insulin index is also useful for providing a direct measure of the insulin response to a food.
The glycemic index of a food is defined as the incremental area under the two-hour blood glucose response curve (AUC) following a 12-hour fast and ingestion of a food with a certain quantity of available carbohydrate (usually 50 g). The AUC of the test food is divided by the AUC of the standard (either glucose or white bread, giving two different definitions) and multiplied by 100. The average GI value is calculated from data collected in 10 human subjects. Both the standard and test food must contain an equal amount of available carbohydrate. The result gives a relative ranking for each tested food.
The current validated methods use glucose as the reference food, giving it a glycemic index value of 100 by definition. This has the advantages of being universal and producing maximum GI values of approximately 100. White bread can also be used as a reference food, giving a different set of GI values (if white bread = 100, then glucose ? 140). For people whose staple carbohydrate source is white bread, this has the advantage of conveying directly whether replacement of the dietary staple with a different food would result in faster or slower blood glucose response. A disadvantage with this system is that the reference food is not well-defined.
Classification: GI values can be interpreted intuitively as percentages on an absolute scale and are commonly interpreted as follows:
Low GI…..(55 or less fructose;) …….Examples:beans (white, black, pink, kidney, lentil, soy, almond, peanut, walnut, chickpea); small seeds (sunflower, flax, pumpkin, poppy, sesame, hemp); most whole intact grains (durum/spelt/kamut wheat, millet, oat, rye, rice, barley); most vegetables, most sweet fruits (peaches, strawberries, mangos); tagatose; mushrooms; chilis.
Medium GI…..(56–69 Examples: white sugar or sucrose, not intact whole wheat or enriched wheat, pita bread, basmati rice, unpeeled boiled potato, grape juice, raisins, prunes, pumpernickel bread, cranberry juice, regular ice cream, banana.
High GI….….(70 and above) Examples: glucose (dextrose, grape sugar), high fructose corn syrup, white bread (only wheat endosperm), most white rice (only rice endosperm), corn flakes, extruded breakfast cereals, maltose, maltodextrins, sweet potato , white potato , pretzels, bagels.
A low-GI food will release glucose more slowly and steadily, which leads to more suitable postprandial (after meal) blood glucose readings. A high-GI food causes a more rapid rise in blood glucose levels and is suitable for energy recovery after exercise or for a person experiencing hypoglycemia.
The glycemic effect of foods depends on a number of factors, such as the type of starch (amylose versus amylopectin), physical entrapment of the starch molecules within the food, fat and protein content of the food and organic acids or their salts in the meal — adding vinegar, for example, will lower the GI. The presence of fat or soluble dietary fiber can slow the gastric emptying rate, thus lowering the GI. In general, coarse, grainy breads with higher amounts of fiber have a lower GI value than white breads. However, most breads made with 100% whole wheat or wholemeal flour have a GI not very different from endosperm only (white) bread. Many brown breads are treated with enzymes to soften the crust, which makes the starch more accessible (high GI).
While adding fat or protein will lower the glycemic response to a meal, the relative differences remain. That is, with or without additions, there is still a higher blood glucose curve after a high-GI bread than after a low-GI bread such as pumpernickel.
Fruits and vegetables tend to have a low glycemic index. The glycemic index can be applied only to foods where the test relies on subjects consuming an amount of food containing 50 g of available carbohydrate. But many fruits and vegetables (not potatoes, sweet potatoes, corn) contain less than 50 g of available carbohydrate per typical serving. Carrots were originally and incorrectly reported as having a high GI. Alcoholic beverages have been reported to have low GI values; however, beer was initially reported to have a moderate GI due to the presence of maltose. This has been refuted by brewing industry professionals, who say that all maltose sugar is consumed in the brewing process and that packaged beer has little to no maltose present. Recent studies have shown that the consumption of an alcoholic drink prior to a meal reduces the GI of the meal by approximately 15%. Moderate alcohol consumption more than 12 hours prior to a test does not affect the GI.
Many modern diets rely on the glycemic index, including the South Beach Diet, Transitions by Market America and NutriSystem Nourish Diet. However, others have pointed out that foods generally considered to be unhealthy can have a low glycemic index, for instance, chocolate cake (GI 38), ice cream (37), or pure fructose (19), whereas foods like potatoes and rice have GIs around 100 but are commonly eaten in some countries with low rates of diabetes.
The GI Symbol Program is an independent worldwide GI certification program that helps consumers identify low-GI foods and drinks. The symbol is only on foods or beverages that have had their GI values tested according to standard and meet the GI Foundation’s certification criteria as a healthy choice within their food group, so they are also lower in kilojoules, fat and/or salt.
Recent animal research provides compelling evidence that high-GI carbohydrate is associated with increased risk of obesity. In one study, male rats were split into high- and low-GI groups over 18 weeks while mean body weight was maintained. Rats fed the high-GI diet were 71% fatter and had 8% less lean body mass than the low-GI group. Postmeal glycemia and insulin levels were significantly higher, and plasma triglycerides were threefold greater in the high-GI-fed rats. Furthermore, pancreatic islet cells suffered “severely disorganized architecture and extensive fibrosis.” However, the GI of these diets was not experimentally determined. In a well controlled feeding study no improvement in weight loss was observed with a low glycemic index diet over calorie restriction. Because high-amylose cornstarch (the major component of the assumed low-GI diet) contains large amounts of resistant starch, which is not digested and absorbed as glucose, the lower glycemic response and possibly the beneficial effects can be attributed to lower energy density and fermentation products of the resistant starch, rather than the GI.
In humans, a 2012 study shows that, after weight loss, the energy expenditure is higher on a low-glycemic index diet than on a low-fat diet (but lower than on the Atkins diet).
Prevention of Diseases:
Several lines of recent  scientific evidence have shown that individuals who followed a low-GI diet over many years were at a significantly lower risk for developing both type 2 diabetes, coronary heart disease, and age-related macular degeneration than others. High blood glucose levels or repeated glycemic “spikes” following a meal may promote these diseases by increasing systemic glycative stress, other oxidative stress to the vasculature, and also by the direct increase in insulin levels. The glycative stress sets up a vicious cycle of systemic protein glycation, compromised protein editing capacity involving the ubiquitin proteolytic pathway and autophagic pathways, leading to enhanced accumulation of glycated and other obsolete proteins.
In the past, postprandial hyperglycemia has been considered a risk factor associated mainly with diabetes. However, more recent evidence shows that it also presents an increased risk for atherosclerosis in the non-diabetic population and that high GI diets, high blood-sugar levels more generally, and diabetes are related to kidney disease as well.
Conversely, there are areas such as Peru and Asia where people eat high-glycemic index foods such as potatoes and high-GI rice without a high level of obesity or diabetes. The high consumption of legumes in South America and fresh fruit and vegetables in Asia likely lowers the glycemic effect in these individuals. The mixing of high- and low-GI carbohydrates produces moderate GI values.
A study from the University of Sydney in Australia suggests that having a breakfast of white bread and sugar-rich cereals, over time, may make a person susceptible to diabetes, heart disease, and even cancer.
A study published in the American Journal of Clinical Nutrition found that age-related adult macular degeneration (AMD), which leads to blindness, is 42% higher among people with a high-GI diet, and concluded that eating a lower-GI diet would eliminate 20% of AMD cases.
The American Diabetes Association supports glycemic index but warns that the total amount of carbohydrate in the food is still the strongest and most important indicator, and that everyone should make their own custom method that works best for them.
The International Life Sciences Institute concluded in 2011 that because there are many different ways of lowering glycemic response, not all of which have the same effects on health, “It is becoming evident that modifying the glycemic response of the diet should not be seen as a stand-alone strategy but rather as an element of an overall balanced diet and lifestyle.”
A systematic review of few human trials examined the potential of low GI diet to improve pregnancy outcomes. Potential benefits were still seen despite no ground breaking findings in maternal glycemia or pregnancy outcomes. In this regard, more women under low GI diet achieved the target treatment goal for the postprandial glycemic level and reduced their need for insulin treatment. A low GI diet may also provide greater benefits to overweight and obese women. Interestingly, intervention at an early stage of pregnancy has shown a tendency to lower birth weight and birth centile in infants born to women with GDM.
The number of grams of carbohydrate can have a bigger impact than glycemic index on blood sugar levels, depending on quantities. Consuming fewer calories, losing weight, and carbohydrate counting can be better for lowering the blood sugar level. Carbohydrates impact glucose levels most profoundly, and two foods with the same carbohydrate content are, in general, comparable in their effects on blood sugar. A food with a low glycemic index may have a high carbohydrate content or vice versa; this can be accounted for with the glycemic load (GL). Consuming carbohydrates with a low glycemic index and calculating carbohydrate intake would produce the most stable blood sugar levels.
Criticism and alternatives:
The glycemic index does not take into account other factors besides glycemic response, such as insulin response, which is measured by the insulin index and can be more appropriate in representing the effects from some food contents other than carbohydrates. In particular, since it is based on the area under the curve of the glucose response over time from ingesting a subject food, the shape of the curve has no bearing on the corresponding GI value. The glucose response can rise to a high level and fall quickly, or rise less high but remain there for a longer time, and have the same area under the curve. For subjects with type 1 diabetes who do not have an insulin response, the rate of appearance of glucose after ingestion represents the absorption of the food itself. This glycemic response has been modeled, where the model parameters for the food enable prediction of the continuous effect of the food over time on glucose values, and not merely the ultimate effect that the GI represents.
Although the glycemic index provides some insights into the relative diabetic risk within specific food groups, it contains many counter-intuitive ratings. These include suggestions that bread generally has a higher glycemic ranking than sugar and that some potatoes are more glycemic than glucose. More significantly, studies such as that by Bazzano et al. demonstrate a significant beneficial diabetic effect for fruit compared to a substantial detrimental impact for fruit juice despite these having similar “low GI” ratings.
From blood glucose curves presented by Brand-Miller et al. the main distinguishing feature between average fruit and fruit juice blood glucose curves is the maximum slope of the leading edge of 4.38 mmol·L-1·h-1 for fruit and 6.71 mmol·L-1·h-1 for fruit juice. This raises the concept that the rate of increase in blood glucose may be a significant determinant particularly when comparing liquids to solids which release carbohydrates over time and therefore have an inherently greater area under the blood glucose curve.
If you were to restrict yourself to eating only low GI foods, your diet is likely to be unbalanced and may be high in fat and calories, leading to weight gain and increasing your risk of heart disease. It is important not to focus exclusively on GI and to think about the balance of your meals, which should be low in fat, salt and sugar and contain plenty of fruit and vegetables.
There are books that give a long list of GI values for many different foods. This kind of list does have its limitations. The GI value relates to the food eaten on its own and in practice we usually eat foods in combination as meals. Bread, for example is usually eaten with butter or margarine, and potatoes could be eaten with meat and vegetables.
An additional problem is that GI compares the glycaemic effect of an amount of food containing 50g of carbohydrate but in real life we eat different amounts of food containing different amounts of carbohydrate.
Note: The amount of carbohydrate you eat has a bigger effect on blood glucose levels than GI alone.
How to have lower GI? *Choose basmati or easy cook rice, pasta or noodles. *Switch baked or mashed potato for sweet potato or boiled new potatoes. *Instead of white and wholemeal bread, choose granary, pumpernickel or rye bread. *Swap frozen microwaveable French fries for pasta or noodles. *Try porridge, natural muesli or wholegrain breakfast cereals. *You can maximise the benefit of GI by switching to a low GI option food with each meal or snack
Indigestion — also called dyspepsia or an upset stomach — is a general term that describes discomfort in your upper abdomen.
It is a term that people use to describe a range of different symptoms relating to the stomach and gastro-intestinal system.
Indigestion is not a disease, but rather a collection of symptoms you experience, including bloating, belching and nausea. Although indigestion is common, how you experience indigestion may differ from other people. Symptoms of indigestion might be felt occasionally or as often as daily.
Fortunately, you may be able to prevent or treat the symptoms of indigestion.
Most people with indigestion have one or more of the following symptoms:
*Early fullness during a meal. You haven’t eaten much of your meal, but you already feel full and may not be able to finish eating.
*Uncomfortable fullness after a meal. Fullness lasts longer than it should.
*Pain in the upper abdomen. You feel a mild to severe pain in the area between the bottom of your breastbone (sternum) and your navel.
*Burning in the upper abdomen. You feel an uncomfortable heat or burning sensation between the bottom of the breastbone and navel.
Less frequent symptoms that may come along with indigestion include:
*Nausea. You feel like you are about to vomit.
*Bloating. Your stomach feels swollen, tight and uncomfortable.
Sometimes people with indigestion also experience heartburn, but heartburn and indigestion are two separate conditions. Heartburn is a pain or burning feeling in the center of your chest that may radiate into your neck or back after or during eating.
It’s not uncommon for people with severe indigestion to think they’re having a heart attack. The pain may be stabbing, or a generalised soreness.
Some people experience reflux – where acidic stomach contents are regurgitated up into the gullet causing a severe burning sensation. Other symptoms include bloating, wind, belching and nausea. Sometimes the pain of indigestion can be relieved by belching.
People of all ages and of both sexes are affected by indigestion. It’s extremely common. An individual’s risk increases with excess alcohol consumption, use of drugs that may irritate the stomach (such as aspirin), other conditions where there is an abnormality in the digestive tract such as an ulcer and emotional problems such as anxiety or depression.
*Aspirin and many other painkillers
*Estrogen and oral contraceptives
*Eating too much, eating too fast, eating high-fat foods,eating fried and toomuch spicy food or eating during stressful situations
*Drinking too much alcohol
*Stress and fatigue
*Swallowing excessive air when eating may increase the symptoms of belching and bloating, which are often associated with indigestion.
Sometimes people have persistent indigestion that is not related to any of these factors. This type of indigestion is called functional, or non-ulcer dyspepsia.
During the middle and later parts of pregnancy, many women have indigestion. This is believed to be caused by a number of pregnancy-related factors including hormones, which relax the muscles of the digestive tract, and the pressure of the growing uterus on the stomach.
Although indigestion doesn’t usually have serious complications, it can affect your quality of life by making you feel uncomfortable and causing you to eat less. When indigestion is caused by an underlying condition, that condition could come with complications of its own.
If you are experiencing symptoms of indigestion, make an appointment to see your doctor to rule out a more serious condition. Because indigestion is such a broad term, it is helpful to provide your doctor with a precise description of the discomfort you are experiencing. In describing your indigestion symptoms, try to define where in the abdomen the discomfort usually occurs. Simply reporting pain in the stomach is not detailed enough for your doctor to help identify and treat your problem.
First, your doctor must rule out any underlying conditions. Your doctor may perform several blood tests and you may have X-rays of the stomach or small intestine. Your doctor may also use an instrument to look closely at the inside of the stomach, a procedure called an upper endoscopy. An endoscope, a flexible tube that contains a light and a camera to produce images from inside the body, is used in this procedure.
Because indigestion is a symptom rather than a disease, treatment usually depends upon the underlying condition causing the indigestion.
Often, episodes of indigestion go away within hours without medical attention. However, if your indigestion symptoms become worse, you should consult a doctor. Here are some helpful tips to alleviate indigestion:
*Try not to chew with your mouth open, talk while chewing, or eat too fast. This causes you to swallow too much air, which can aggravate indigestion.
*Drink fluids after rather than during meals.
*Avoid late-night eating.
*Try to get little relaxation after meals.
*Avoid toomuch spicy and fried foods.
*Avoid alcoholic beverages.
*Maintain a healthy weight. Excess pounds put pressure on your abdomen, pushing up your stomach and causing acid to back up into your esophagus.Exercise regularly. With your doctor’s OK, aim for 30 to 60 minutes of physical activity on most days of the week. It can be as simple as a daily walk, though not just after you eat.
*Regular exercise(specially Yoga exercise ) helps you keep off extra weight and promotes better digestion.
*Manage stress. Create a calm environment at mealtime. Practice relaxation techniques, such as deep breathing, meditation or yoga. Spend time doing things you enjoy. Get plenty of sleep.
*Eat more fibourous food (vegetable,fruits & nuts) and less meat(specially redmeat)
*Reconsider your medications. With your doctor’s approval, stop or cut back on pain relieving drugs that may irritate your stomach lining. If that’s not an option, be sure to take these medications with food.
*Do not exercise with a full stomach. Rather, exercise before a meal or at least one hour after eating a meal.
Do not lie down right after eating.
*Wait at least three hours after your last meal of the day before going to bed.
*Raise the head of your bed so that your head and chest are higher than your feet. You can do this by placing 6-inch blocks under the bedposts at the head of the bed. Don’t use piles of pillows to achieve the same goal. You will only put your head at an angle that can increase pressure on your stomach and make heartburn worse.
*Go to bed early and get up early. Try to have atleast 6 hours sound sleep at night.
If indigestion is not relieved after making these changes, your doctor may prescribe medications to alleviate your symptoms.
Some people may find relief from indigestion through the following methods, although more research is needed to determine their effectiveness:
*Drinking herbal tea with peppermint.
*Psychological methods, including relaxation techniques, cognitive therapy and hypnotherapy.
*You may see herbal products that promise relief from indigestion. But remember, these products often haven’t been proven effective and there’s a risk that comes with taking herbs because they’re not regulated.
*Sometimes proper Homeopathic treatment works very well.

The essence of all being is energy. Our physical and ethereal selves depend on the unrestricted flow of life energy that is the source of wholeness and wellness. Though the channels through which this energy flows are open systems and influenced by factors outside of our control, we ultimately choose what impact these will have in our lives. It is up to us to identify and clear blockages in the energy field to ensure that flow is maintained. A healthy, grounded individual absorbs some portion of the energy emitted by other people and the environment, but this does not interrupt the continuous stream of balanced energy sustaining them. The same individual copes constructively with stress and upset, and they are not subject to the stagnation that frequently goes hand in hand with negativity. When we keep the energy in and around our bodies flowing harmoniously, we are naturally healthy, vibrant, and peaceful.
Life energy flows through us like a swift stream when there is nothing to obstruct it, but various forces such as trauma, downbeat vibrations, and disappointments act like stones that impede the current. If we allow these to pile up, our life energy is thrown off its course or blocked entirely, causing illness, restlessness, and a lack of vigor. If, however, we take the time to clear these forces away, we rob them of the power to impact our lives. When we cultivate simple yet affirmative habits such as taking regular cleansing baths, practicing meditation and breathing exercises, smudging, and self-shielding, we protect ourselves from outside influences that might otherwise impede our energy flow. Likewise, we lessen the impact of inner influences when we clear our auras of unwanted attachments and divest ourselves of blocked emotions.
A strong and fluid energy field is the key that unlocks the doors of self-healing and peace of mind. Your awareness of the flow of energy sustaining you empowers you to take charge of your own well-being by taking steps to unblock, correct, and enhance that flow. Fear will likely be the culprit when you cannot identify the source of stagnation—you may simply be afraid to let go of what is obstructing the flow. Letting go can be challenging, but the exuberance you will feel when the flow is restored will be a welcome and blessed reward.
The saturated fat found mainly in meat and dairy products has been regularly vilified by physicians and the media, but a new analysis of published studies finds no clear link between people’s intake of saturated fat and their risk of developing heart disease.
