| Microgreens more nutritious than mature plants Posted: 01 Sep 2012 03:51 AM PDT  Some microgreens have more nutrients than mature plants, says a new study. – shutterstock.com Microgreens have become a trendy ingredient in the restaurant scene to add colour, texture and flavour to dishes, sometimes as a garnish and other times as an ingredient. Seedlings of spinach, lettuce and red cabbage are usually 2.5 cm to 8 cm in height and are harvested within 14 days of germination. Among the 25 microgreens analyzed, scientists found that the seedlings of red cabbage, cilantro, red garnet amaranth (a purple-hued plant) and green daikon radish had the highest concentrations of nutrients like ascorbic acids, carotenoids, phylloquinone or vitamin K, and tocopherols or vitamin E, all of which have antioxidant properties. The study was published in the Journal of Agricultural and Food Chemistry August 29. Red cabbage microgreens had the highest concentration of vitamin C, while green daikon radish microgreens were packed with the most vitamin E. Meanwhile, to prepare microgreens at home, Epicurious takes inspiration from acclaimed restaurant Noma in Copenhagen, renowned for foraging its ingredients, with a recipe for microgreens with a curry vinaigrette. Popular food blog Honest Cooking also suggests topping pizza with fresh microgreens for added texture, eating them as a salad, and adding them to sushi, wraps and sandwiches. – AFP/Relaxnews |
| Shisha smoking as bad as cigarettes, study finds Posted: 31 Aug 2012 11:57 PM PDT  A shisha smoker may inhale the equivalent of 100 cigarettes' worth of smoke in a session.—Picture by Chubykin Arkady/Shutterstock.com Researchers led by Mohammad Hossein Boskabady at Masshad University of Medical Sciences in Iran monitored lung functions among 57 local water-pipe smokers, 30 deep-inhalation cigarette smokers and 51 normal-inhalation smokers. They also studied 44 non-smokers for a comparison. Wheezing occurred among 23 per cent of the water-pipe users, 30 per cent of the deep-inhalation and 21.6 per cent of normal-inhalation cigarette smokers, but only among 9.1 per cent of non-smokers. Coughing occurred among 21 per cent, 36.7 per cent and 19.6 per cent of the smoking groups, compared with 6.8 per cent of non-smokers, according to the probe, which measured smokers over three months in two consecutive years. Sputum production, meanwhile, was found in 14 per cent, 10 per cent, 3.9 per cent respectively among the various smoking groups, but among 6.8 per cent of the non-smoking group. The results, published in the peer-reviewed journal Respirology, added that a further scientific blow to the defenders of shisha who claim that water pipes are safer because they filter out tobacco toxins. The water pipe, often used with sweet or fruit-flavoured tobacco, is a centuries-old tradition in the Middle East but in recent years has become fashionable among young westerners, particularly women. "Our findings reveal that there were profound effects of water-pipe smoking on lung function values, which were similar to the effects observed in deep-inhalation cigarette smokers," Boskabady said in a press release. "Normal" inhalation cigarette smoking had less of an effect compared to the water pipe, but still contributed significantly to respiratory disorders, the paper stressed. According to a 2005 study by the UN World Health Organisation (WHO), water pipe smoke has high concentrations of toxic compounds, including carbon monoxide, heavy metals, cancer-causing chemicals and potentially addictive levels of nicotine. Cigarette smokers typically take eight to 12 puffs over five to seven minutes, inhaling a total of 0.5 to 0.6 of a litre of smoke. In contrast, waterpipe sessions typically last 20-80 minutes, during which the smoker may take 50-20 puffs that each range from 0.15 to one litre each. "The waterpipe smoker may therefore inhale as much smoke during one session as a cigarette smoker would inhale consuming 100 or more cigarettes," the WHO said. The Iranian research used a gadget called a spirometer to measure how deeply smokers inhaled and retained the puff. "Normal" inhalers typically inhaled less than 10 per cent above a benchmark of lung inflation called tidal volume. For "deep" inhalers, it was typically more than 30 per cent, and for water-pipe smokers it was usually 40 per cent above tidal volume. — AFP/Relaxnews |
