The lung cancer risk of a woman does not appear to be associated with the number of children she has, although some scientists had thought hormonal changes during pregnancy may protect against the disease.

“If you look at the component studies, they are all over the map,” she told Reuters Health, adding that she and her colleagues had hoped to be able to explain that variation.

“We came up relatively empty-handed,” Jessica K. Paulus, who worked on the analysis and of Tufts University in Medford, Massachusetts, said. “It makes it difficult to interpret our findings.” “Both active smoking and exposure to second-hand smoking are some of the strongest risk factors for lung cancer,” said Paulus. “Quitting smoking and quitting soon is associated with reducing your risk of lung cancer.”

In a report released on Thursday, the UK department of health said most adults in the nation of 60 million people are eating about 10 percent more calories than necessary.

Officials said the country needs to collectively trim 5 billion calories from its daily diet to stop the bulging waistlines.

But in a slightly confusing twist, the government also issued new calorie recommendations that are about 100 calories higher than the last figures in 1991. Men are now allowed to eat about 2,605 calories of food every day while for women, it’s 2,079.

British officials say the new numbers are based on a better understanding of current activity levels and that an individual’s ideal calorie count varies depending on factors like how much they exercise and their body mass index. Previous calorie recommendations underestimated the impact of physical activity, even though people are now more sedentary than two decades ago.

“This is not a license to eat more,” said Alan Jackson, head of the scientific group that came up with the new recommendations.

Pain (any pain–emotional, physical, mental) has a message. The information it has about our life can be remarkably specific, but it usually falls into one of two categories: “We would be more alive if we did more of this,” and, “Life would be more lovely if we did less of that.” Once we get the pain’s message, and follow its advice, the pain goes away. – Peter McWilliams, Life 101
