Americans find doing their own taxes simpler than improving diet and health

ScienceDaily (May 23, 2012) — Most Americans (52 percent) have concluded that figuring out their income taxes is easier than knowing what they should and shouldn't eat to be healthier, according to the International Food Information Council (IFIC) Foundation's 2012 Food & Health Survey.

The Survey found that people think a great deal about the healthfulness of their diets and want to make improvements. Yet, 76 percent agree that ever-changing nutritional guidance makes it hard to know what to believe. And when it comes to making decisions about food, consumers today rely most often on their own research rather than third-party experts. Six out of 10 Americans have given a lot of thought to the foods and beverages they consume (58 percent) and the amount of physical activity they get (61 percent). Yet, only 20 percent say their diet is very healthful and 23 percent describe their diet as extremely or very unhealthful; less than 20 percent meet the national Physical Activity Guidelines.

"This year's Survey was designed to reveal consumer behavior, not just thoughts and desires. Clearly, there is a disconnect for many Americans," said Marianne Smith Edge, MS, RD, LD, FADA, Senior Vice President, Nutrition and Food Safety, IFIC Foundation. "Some questions also reveal clear differences based on gender and age. For example, men feel it is harder to eat a healthful diet than to find time to exercise, while women feel just the opposite. The percentage of older respondents who say their diet is very or extremely healthful is about twice the rate of younger people. These are important distinctions for health professionals and others who are trying to help individuals and families improve their diet and health."

The IFIC Foundation's 2012 Food & Health Survey found that 90 percent of Americans have given at least a little thought to the ingredients in their food and beverages. Consumers say they are trying to eat more whole grains, fiber and protein, while cutting calories, sugar, solid fats and salt. However, taste (87 percent) remains the most significant determinant of food and beverage choices, followed by price, which dropped significantly as a factor compared to 2011, and healthfulness. In terms of trying to lead healthier lives, nearly 60 percent of Americans believe that online and mobile tools are helpful.

The Survey was fielded by Mathew Greenwald & Associates of Washington, D.C. between April 3 and 13, 2012 and involved 1,057 Americans ages 18 to 80. Results were weighted to match the U.S. Census based on age, education, gender, race/ethnicity, and region to be nationally representative.

Additional Findings from the IFIC Foundation's 2012 Food & Health Survey

• Overall, 55 percent of Americans are trying to lose weight. However, 23 percent of obese consumers and 44 percent of overweight consumers say they are not trying to lose weight.

• Fewer than one in 10 Americans correctly estimate the number of calories they need to maintain their weight and only three in 10 believe that all sources of calories play an equal role in weight gain. Calories from sugar, carbohydrates and fats are believed more likely to cause weight gain.

• During the past year, 66 percent of Americans have given some thought to the sustainability of their foods and beverages, with about 40 percent regularly purchasing locally sourced or recyclable food and beverage products.

• Only 17 percent of Americans say they have stopped buying a specific brand or type of food due to safety concerns and more than half of all consumers (57 percent) believe that the chances are extremely low that they will contract a serious foodborne illness. About half (48 percent) believe foods produced in foreign countries are less safe than foods grown in the U.S.

• The expiration date surpassed the food package Nutrition Facts panel in terms of the information consumers looked for in making food or beverage purchases, although the importance of statements about nutrition and health benefits both rose significantly.

• Six in 10 Americans believe the U.S. Food and Drug Administration (FDA) regulates how food additives may be used but only 36 percent realized the FDA approves or sets daily intake limits for food additives. About half (46 percent) of Americans believe that food colors must be reviewed and approved by the U.S. government before being added to foods.

• Eighty-seven percent of parents believe that it is good for their health to sit down and eat meals with their family and 69 percent of parents worry about the healthfulness of their children's diets more than their own.

• The United States Department of Agriculture's MyPlate graphic was readily recognized by consumers and received high marks for communicating about healthful eating.

Caesarean section delivery may double risk of childhood obesity: May be due to different gut bacteria

ScienceDaily (May 23, 2012) — Caesarean section delivery may double the risk of subsequent childhood obesity, finds research published online in the Archives of Disease in Childhood.

See Also:Health & MedicinePregnancy and ChildbirthObesityGynecologyDiet and Weight LossInfant's HealthChildren's HealthReferenceBreech birthBirth weightBody mass indexNutrition and pregnancy

Caesarean section delivery has already been linked to an increased risk of subsequent childhood asthma and allergic rhinitis, and around one in three babies born in the US is delivered this way.

The authors base their findings on 1255 mother and child pairs, who attended eight outpatient maternity services in eastern Massachusetts, USA between 1999 and 2002.

The mums joined the study before 22 weeks of pregnancy, and their babies were measured and weighed at birth, at six months, and then at the age of three, when the child's skinfold thickness, a measure of body fat, was also assessed.

Out of the 1255 deliveries, around one in four (22.6%; 284) were by caesarean section, and the remainder (77.4%; 971) were vaginal deliveries.

Mums who delivered by c-section tended to weigh more than those delivering vaginally, and the birthweight for gestational age of their babies also tended to be higher. These mums also breastfed their babies for a shorter period.

But irrespective of birth weight, and after taking account of maternal weight (BMI) and several other influential factors, a caesarean section delivery was associated with a doubling in the odds of obesity by the time the child was 3 years old.

Just under 16% of children delivered via c-section were obese by the age of 3 compared with 7.5% of those born vaginally.

Children delivered by c-section also had higher BMI and skinfold thickness measurements by the age of 3.

The researchers speculate that one possible explanation for their findings is the difference in the composition of gut bacteria acquired at birth between the two delivery methods.

They highlight previous research showing that children born by c-section have higher numbers of Firmicutes bacteria and lower numbers of Bacteroides bacteria in their guts. These two groups make up the bulk of gut flora.

Other research has also suggested that obese people have higher levels of Firmicutes bacteria.

It may be that gut bacteria influence the development of obesity by increasing energy extracted from the diet, and by stimulating cells to boost insulin resistance, inflammation, and fat deposits, say the authors.

"An association between caesarean birth and increased risk of childhood obesity would provide an important rationale to avoid non-medically indicated caesarean section," write the authors.

Mums who choose this delivery option should be made aware of the potential health risks to her baby, including the possibility of obesity, they say.

Calcium supplements linked to significantly increased heart attack risk, study suggests

ScienceDaily (May 23, 2012) — Calcium supplements might increase the risk of having a heart attack, and should be "taken with caution," concludes research published in the online issue of the journal Heart.

Furthermore, boosting overall calcium intake from dietary sources confers no significant advantage in terms of staving off heart disease and stroke, the findings indicate.

Previous research has linked higher calcium intake with a lowered risk of high blood pressure, obesity, and type 2 diabetes, all of which are risk factors for heart disease and stroke.

And calcium supplements are commonly recommended to elderly people and women who have gone through the menopause to prevent bone thinning.

The authors base their findings on almost 24,000 participants of one of the German arms of the European Prospective Investigation into Cancer and Nutrition (EPIC) study in Heidelberg.

All the participants were aged between 35 and 64 when they joined the study in 1994-8.

Normal diet for the preceding 12 months was assessed using food frequency questionnaires and they were quizzed about whether they regularly took vitamin or mineral supplements.

Their health was tracked for an average of 11 years, during which time 354 heart attacks, 260 strokes, and 267 associated deaths occurred.

After taking account of factors likely to influence the results, those whose diets included a moderate amount (820 mg daily) of calcium from all sources, including supplements, had a 31% lower risk of having a heart attack than those in the bottom 25% of calcium intake.

But those with an intake of more than 1100 mg daily did not have a significantly lower risk. There was no evidence that any level of calcium intake either protected against or increased the risk of stroke, which backs up the findings of other research, say the authors.

But when the analysis looked at vitamin/mineral supplements, it found that those who took calcium supplements regularly were 86% more likely to have a heart attack than those who didn't use any supplements.

And this risk increased further among those who used only calcium supplements. They were more than twice as likely to have a heart attack as those who didn't take any supplements.

The authors conclude: "This study suggests that increasing calcium intake from diet might not confer significant cardiovascular benefits, while calcium supplements, which might raise
