Keep off food colours: Experts


INDORE: That tempting brown pastry at the bakery, bright yellow jalebi, and blue coloured ice ball to relieve you from the heat. The colourful eatables may look like a good treat for your taste buds, but it might as well get you many life threatening diseases. Food colours that have become irreplaceable ingredients of most of our meals might help improve appearance of a dish. But it can be responsible for causing many irreversible effects on our health.

From carcinogens or cancer causing agents in some cases containing toxins like lead and arsenics, a few food colours might lead to severe health hazards. Gastroenterologist Dr Atul Shende sharing his recent experiences wherein food colours came up to be as cause of certain abdominal ailments, said, "Recently we have been receiving many young patients with pancreatitis, it's a condition where pancreas is known to get inflamed. The most common cause for this condition is alcohol consumption or gall bladder stone."

Elaborating, he said, "But in last few cases, patients I treated for this condition were young children. Also, all of them said they had consumed chocolate or black forest pastry, which are known to contain brown food colour. "Not that it had been studied yet, but Shende seemed to be sure of his observation and might take the matter up the matter with food officer." "We are not very sure of the chemical composition of the brown food colour, but I am confident that it has to be blamed. With the uniformity in the cases of pancreatitis and their causes there nothing to suggest otherwise, we might write to the food officer about it in the future."

It's not just one colour which can be treated as a health hazard, chief dietician, Mohak Hospital, Dr Preeti Shukla said, "Food colours that we add to our meals at home to make our food look attractive can cause lifelong damage to body and brain. There are certain colours which cause insomnia, lack of appetite, gastro intestinal problems, skin problems, and some can even lead to cancer. I personally suggest my patients to stay away from such ingredients."

Although there is no getting away from these colours when decide to go out and eat "When you eat at a hotel, and if you happen to order a dish which might have added colours, it would show on your fingers even when washed. So avoid ordering the same dish the next time you eat out or may be eat somewhere else. Eating Chinese food outside can also lead to many health troubles, it contains Ajinomoto or Monosodium glutamate (MSG) which known to have many harmful effects."

Food Officer Indore, Manish Swamy said, "Packaged food that sells in markets normally have food grade colours and are used to according to Food and Drug Administration (FDA) standards. Apart from that we conduct regular inspection at eateries and hotels in the city. At an average, 10 hotels are inspected every month. Action is taken against any one found violating rules.

Enzyme makes diabetic patients prone to heart attacks

MUMBAI: Patients with diabetes are known to be more prone to heart attacks. Now, a study from University of Iowa has worked out why this happens.
Studying mice with diabetes, they realized that patients with the diabetes have higher levels of a heart enzyme called CaMKII (calcium/calmodulin-dependent protein kinase II). An analysis showed that heart rates in the diabetic mice slowed dramatically and, like humans with diabetes, the mice had double the death rate after a heart attack compared to non-diabetic mice.
The team studied the heart's pacemaker cells because most deaths showed abnormalities on the rhythm of the heart. "Many studies have shown that patients with diabetes are at especially high risk for dying from a myocardial infarction (heart attack). Our study provides new evidence that this excess mortality could involve a pathway where oxidized CaMKII enzyme plays a central role," the study's lead author Mark Anderson has been quoted as saying.
The study, published in the Journal of Clinical Investigation, found thatpacemaker cells had elevated levels of oxidized CaMKII enzyme and more cell death than pacemaker cells in non-diabetic mice. Interestingly, when the team blocked oxidation-based activation of the enzyme, fewer pacemaker cells died. The study thus shows that by reducing activation of the CaMKII enzyme in heart cells may reduce the risk of death due to heart attack in patients with diabetes.

Now, a device to predict heart attacks


LONDON: Scientists claim to have developed a tiny under-the-skin implant which can predict a heart attack in advance by several hours. The device, developed by Swiss scientists, is just 1.4cm long, and can check up to five different substances in the blood around the clock and transmit the results to a doctor's computer.

The sensors target proteins, sugar and organic acids in the blood that provide vital health information.

For patients with chronic illnesses, such as cancer or diabetes, the device could provide continuous monitoring and sound an alert before symptoms emerge.

Scientists believe the implant will be especially useful as a chemotherapy aid. Currently doctors rely on occasional blood tests to assess a cancer patient's tolerance of a particular treatment dosage. However, it is difficult to tailor the ideal dose for an individual patient.

The inventors said the tiny "labon-a-chip" could be used to give an early warning of a heart attack, or monitor cancer patients having chemotherapy . Giovanni de Micheli of the Ecole Polytechnique Federale de Lausanne said the chip can be "programmed" by coating it with chemicals which react with substances that doctors want to monitor, Sky News reported.

"It comes in contact with fluids in the body. The sensors react to the presence of particular compounds in the fluids and send the data outside," Micheli said. A patch on the surface of the skin powers the chip and transmits the information via Bluetooth to a smartphone or a tablet, which then relays it on to the doctor.

Sandro Carrara, another of the inventors, said the chip had huge potential . "This device can predict a heart attack in advance by several hours thanks to the metabolites released by the heart when it is suffering," he said.

The prototype is being unveiled at DATE 13, (Design Automation & Test in Europe) Europe's largest electronics conference. The scientists hope the device will be commercially available within four years.
