Sugar May Be Bad, But This Sweetener Is Far More Deadly, Part 1 of 3 - 4 views

  •  
    "Scientists have proved for the first time that fructose, a cheap form of sugar used in thousands of food products and soft drinks, can damage human metabolism and is fueling the obesity crisis.

    Fructose, a sweetener usually derived from corn, can cause dangerous growths of fat cells around vital organs and is able to trigger the early stages of diabetes and heart disease.

    Over 10 weeks, 16 volunteers on a controlled diet including high levels of fructose produced new fat cells around their heart, liver and other digestive organs. They also showed signs of food-processing abnormalities linked to diabetes and heart disease. Another group of volunteers on the same diet, but with glucose sugar replacing fructose, did not have these problems."

Fat in diet won't affect weight gain over time | Reuters - 1 views

  •  
    "NEW YORK (Reuters Health) - People who want to maintain a healthy weight over time shouldn't obsess about their fat intake, new research shows.

    The percentage of calories that a person got from fat, as opposed to protein or carbohydrates, had nothing to do with how much weight they gained in the coming years, the research team found.

    The kinds of fat they ate didn't matter either, Dr. Nita Forouhi of the Institute of Metabolic Science, Addenbrooke's Hospital, Cambridge, UK and her colleagues found.

    The findings, Forouhi noted in an email to Reuters Health, show that "it is more important to aim for a healthy lifestyle including a balanced healthy diet and regular physical activity, than to focus on fat intake alone as a factor for weight gain.""

Body mass and waist size can predict heart disease | Reuters - 0 views

  •  
    "A large 10-year study found that half of all fatal heart disease cases and a quarter of all non-fatal cases are linked to being overweight and having a high body mass index (BMI) or large waist.

    Body mass index and waist circumference are well known risk factors for cardiovascular diseases but the Dutch researchers said their work showed BMI and waist size could actually help predict the risk of dying from or developing heart disease."

Obesity Linked with Smaller Brain Size - Health & Science - CBN News - Christian News 2... - 0 views

  •  
    "A new study finds that obese people have brains that eight percent smaller than thin people and those brains look 16 years older.

    Live Science.com reports that this condition makes it harder to think and puts people at greater risk for Alzheimer's and other diseases.

    The results, based on brain scans of 94 people in their 70s, represent "severe brain degeneration," said Paul Thompson, senior author of the study and a UCLA professor of neurology. "

Findings show insulin -- not genes -- linked to obesity - 0 views

  •  
    WEST LAFAYETTE, Ind. - Researchers have uncovered new evidence suggesting factors other than genes could cause obesity, finding that genetically identical cells store widely differing amounts of fat depending on subtle variations in how cells process insulin.

    Learning the precise mechanism responsible for fat storage in cells could lead to methods for controlling obesity.

    "Insights from our study also will be important for understanding the precise roles of insulin in obesity or Type II diabetes, and to the design of effective intervention strategies," said Ji-Xin Cheng, an assistant professor in Purdue University's Weldon School of Biomedical Engineering and Department of Chemistry.

    Findings indicate that the faster a cell processes insulin, the more fat it stores.

Does Eating Fewer Calories Improve the Brain?: Scientific American - 0 views

  •  
    Hara hatchi bu, the Okinawan people's habit of eating only till they are 80 percent full, is thought to be one of the secrets of their extraordinary health and longevity. In addition to one of the highest percentages of people in the world who live past 100, Okinawans appear to be less prone to heart disease, diabetes and obesity.

    Indeed, ever since it was discovered in the 1930s that laboratory rats fed a caloric-restricted (CR) diet lived almost twice as long as their well fed counterparts, scientists have pursued caloric restriction research in the hopes of finding novel strategies for extending human life and preventing disease. Given the growing older population at risk for memory problems and the rising rates of obesity, the role of diet in maintaining peak brain performance has taken on added importance.

Not enough vitamin D in the diet could mean too much fat on adolescents - 0 views

  •  
    AUGUSTA, Ga. - Too little vitamin D could be bad for more than your bones; it may also lead to fatter adolescents, researchers say.\n\nA Medical College of Georgia study of more than 650 teens age 14-19 has found that those who reported higher vitamin D intakes had lower overall body fat and lower amounts of the fat in the abdomen, a type of fat known as visceral fat, which has been associated with health risks such as heart disease, stroke, diabetes and hypertension

Genetically Altered Mice Stay Lean With High-Carb Diet - 0 views

  •  
    Researchers at the University of California, Berkeley, have identified a gene that plays a critical regulatory role in the process of converting dietary carbohydrates to fat. In a new study, they disabled this gene in mice, which consequently had lower levels of body fat than their normal counterparts, despite being fed the equivalent of an all-you-can-eat pasta buffet.

    The authors of the study, to be published in the March 20 issue of the journal Cell, say the gene, called DNA-PK, could potentially play a role in the prevention of obesity related to the over-consumption of high-carbohydrate foods, such as pasta, rice, soda and sugary snacks..

Omega-3 Fatty Acids Prevent Medical Complications Of Obesity, Study Suggests - 0 views

  •  
    ScienceDaily (Feb. 12, 2009) - According to a recent study, diets rich in omega-3 fatty acids protect the liver from damage caused by obesity and the insulin resistance it provokes. This research should give doctors and nutritionists valuable information when recommending and formulating weight-loss diets and help explain why some obese patients are more likely to suffer some complications associated with obesity. Omega-3 fatty acids can be found in canola oil and fish.
