A handful of nuts daily keeps heart healthy

A daily dose of nuts — walnuts, almonds, pistachios — can make up for a heart-healthy diet, according to Mayo Clinic researchers.
Most nuts contain some nutrients that can benefit heart health and help with cholesterol control. They include unsaturated fats, omega-3 fatty acids, fibre, 1-arginine and plant sterols. Nuts have been shown to reduce low-density lipoproteins (LDL, or ‘bad’ cholesterol) levels in the blood.
Eating nuts also can reduce the risk of developing blood clots and improve the health of the lining of the arteries.
The above benefits suggest that eating nuts, in limited amounts, may reduce the risk of heart disease, though studies haven’t yet proved this conclusively.
Almost any type of nut is nutritious — and high in calories. It is best to eat nuts in moderation, no more than a handful a day. Also, choose unsalted or low-salt versions.

Human milk improves nutritional outcomes

Human milk can significantly improve nutritional and neurodevelopmental outcomes in premature babies, say experts. University of California, San Diego Health Sciences have recently launched a website dedicated to offering families and the medical community valuable information about the best way to provide human milk to premature and underweight infants.
Infants born prematurely sometimes develop an infection called necrotising enercolitis (NEC), the most common life-threatening gastrointestinal emergency in the newborn period. It causes intense inflammation and acute intestinal necrosis or death.
“One of the goals of this website is to help fellow hospitals adapt our model of human milk nutrition in their own neonatal intensive care units,” said Dr Jae Kim.
Calorie counts used as basis of diet plans may be wrong
Calorie guidelines followed by Britons to date have all been deemed incorrect in a new research. Weight conscious individuals, who religiously stick to the advised 2,000 calories a day limit for women and 2,500 for men, could be depriving themselves of food unnecessarily, the study suggests.
In a major review of the official calorie advice, researchers found that these amounts could be raised as much as 16 per cent from the guidelines developed in 1991.
And this is because nutrition experts under-estimated physical activity levels in the UK and set advice on energy intake too low.
A 16 per cent increase would boost an adult’s daily limit by as much as 400 calories — equal to eating a regular cheeseburger or two packets of ready-salted crisps.
But increasing the daily calorie guidelines would pose problems for nutrition experts desperately trying to reverse the obesity epidemic.

Mouth can indicate body’s overall health

The mouth or oral cavity area is an excellent indicator of the whole body’s health, says a University of Maryland Dental School professor.
Li Mao insists surface tissues inside the cheek could be checked to detect tobacco-induced damage in the lungs. This could prove to be an important advancement in designing future lung cancer prevention trials.
“We hypothesised that tobacco-induced molecular alterations in the oral epithelium are similar to those in the lungs,” said Mao.
The expert added: “This might have broader implications for using the mouth as a diagnostic indicator for general health.”
“I feel that dentists should play a major role in prevention of cancer and Dr Mao is the leading oral cancer researcher in the country. He crosses the bridge between medicine and dentistry,” said University of Maryland Dental School Dean Christian S Stohler.
