Are Artificial Sweeteners helping you lose Weight?

If you have been trying to reduce weight by substituting sugar with low-calorie artificial sweeteners, and not shrinking much, you are not alone!  Recent data shows why things may not be working out as well as we had imagined.
Sugar containing sweets do cause rapid rise in blood sugar levels, something that diabetics need to avoid. A wide range of sugar substitutes are now available to add a measure of sweetness to their lives and for their taste buds. They can now eat all types of mithai, kheer, pastries baked goods, soft drinks, candy, puddings, canned foods, jams and jellies, dairy products, and scores of other foods and beverages. Artificial sweeteners are attractive alternatives to sugar because they add virtually no calories to your diet. In addition, you need only a fraction compared with the amount of regular sugar you would normally use for sweetness.
If however losing weight is your target, artificial sweeeteners have not delivered as well as predicted. Despite the switch to these expensive products, the needle on your weighing machine may seem stuck for months, or worse, move further right.
Doctors at the Mayo Clinic have been trying to study this unexpected phenomenon, and are pursuing several lines of research. Some artificial sweeteners enhance appetitite thereby making you eat more. There could be a psychological element too, as you may be eating 2 pastries instead of one, once you are aware that they are low-cal.  
Another explanation is that the brain needs to sense sugar in the blood to turn off hunger; as artificial sweeeteners are calorie-less, hunger persists making us gorge more, making the other components in a pastry, such as starch and fat, push our weight up.
There are 3 broad groups of sweeteners in use today. The 1st group is artificial sweeteners, and include Acesulfame potassium (Sunett, Sweet One), Aspartame (Equal, Sugar Free Gold, NutraSweet), Neotame, Saccharin (Kaltame, Sweet'N Low) and Sucralose (Splenda, Sugar Free natura). While some give an after-taste they are generally safe, contain no calories, and do not cause tooth decay.
The 2nd group is that of sugar alcohols (polyols) that occur naturally in certain fruits and vegetables but can be manufactured as well.  They are not intense sweeeteners, contain some calories (though much less than sugar) and are considered “healthier”.  Examples are Erythritol, Lactitol, Mannitol, Sorbitol and Xylitol. They may cause loose stools and could be of help to habitual constipators.
The 3rd group consists of natural sweeteners such as date sugar, grape juice concentrate, honey, maple sugar, maple syrup, molasses and agave nectar. They contain calories, as does your refined sugar, and cause tooth decay, but serve the dual functions of a sweetener and a flavouring agent, especially for some dishes.
If I have left you wondering which one to choose, here is my advice. Don’t stick to one but try a mix-and-match approach to suit your palate and your needs. Balance will still remain the key. Bon appetite!

Food Fads in Liver Disorders

By
In an attempt at trying to do well to those they love, spouses and parents often enforce diets on patients of liver diseases that often turn out to be detrimental. The commonest food fad is pale insipid boiled cabbage being doled out to nauseous patients suffering from hepatitis that makes them puke even more.  The liver, in a way, is a buzzing manufacturing unit that requires lots of energy to keep its multiple functions going. And it derives all this from the food we eat. During disease, such as during an attack of jaundice, when many of the liver cells get killed, the liver attemptsdamage control by trying to regenerate quickly. For its cells to multiply however, it requires a generous supply of energy that comes from carbohydrates, and protein, the building block for its cells and tissues. Boiled green vegetables unfortunately have neither of these. Hence the situation often progresses to that of a starved liver unable to recuperate due to cut-off food supply.

Bad Dreams, Disturbed Sleep

By
  A good night’s sleep, so essential to rest your body and mind, and restore ‘energy” and vitality, is becoming a casualty for many these days. Last week a 58 year old lady complained that she woke up with a startle in the middle of the night dreaming of “drugs”, something she had never been exposed to all her life. Another reported a nightmare in which he felt someone was “strangulating” him by tightening something around his neck, till he woke up feeling choked! Yet another reported dreaming that he was in an ICU of a hospital with PPE draped figures surrounding his bed while he was being prepared to be hooked to a ventilator. Bad dreams can be disturbing to say the least. One wakes up with a startle or in sweat, feeling disturbed and uneasy, and feeling drained. The mood in the morning is usually uneasy and snappy. Creative thinking has usually gone for a toss…postponed to yet another day when one feels more cheerful and positive.   Several factors could be contributing to “

The Doctor’s Dress

By
The familiar white coat worn by physicians as their distinctive dress for over 100 years, has started generating  murmurs  of controversy. It is not uncommon to find the blood pressure to be higher when measured by a white-coat-wearing-doctor in the hospital or clinic than the readings obtained at home by relatives.  This is due to the anxiety that the white coat and the hospital setting evokes in patients, and has been termed “White Coat Hypertension”. Mature clinicians often routinely subtract a few points from these measurements when entering records in case charts or calculating the dose of anti-hypertensive medications to be prescribed. The white coat scares children too.  Kids often express their dislike for this dress by crying and screaming and by denying access to their bellies or chest for examination by paediatricians in this attire. Many pediatricians across the world have folded up their white coats and taken to informal colourful dressing to get closer to thei
