The Sandwich Trend: Convenience, Economy, Health, And Exotic Varieties

Americans have discovered – or re-discovered – the convenience and economy of sandwiches, and restaurants have caught on to the trend. Pizza Hut, for example, has added sandwiches to their menu, but with a twist. They package sausage, pepperoni, ham, Italian steak and Buffalo chicken into a rolled pizza crust sandwich. A Technomic report found that 41 percent of consumers ages 25 to 34 want restaurants to offer mini-sandwiches that can be eaten as a snack or light meal, like McDonald's wrap sandwiches. The most popular sandwich in the U.S. these days? According to a food consultant, it’s the Vietnamese banh mi sandwich, a concoction of grilled pork, chicken or beef, pickled vegetables and cilantro.

Lupin-Based Breakfast Cereal: Healthier Than Wheat-Based Products?

An Australian university professor has developed a breakfast cereal based on the traditional feed grain lupin that, he says, is healthier than wheat-based breakfast cereals. The cereal is gluten-free, high in fiber and protein, low in fat, and cholesterol free. In addition, the cereal has a low glycemic index, so it takes longer for the digestive system to process, helping people to avoid hunger pangs and snacking.

Researcher Forecasts Increased Growth For “Healthier” Breads

The trend away from white bread toward “healthier” breads continues, according to recent industry sales stats. IBISWorld reports that white bread still accounts for 45 percent of total bread sales, but it’s losing ground to whole-grain, organic, gluten-free, seeded and artisan breads. The latter two offer significant growth opportunities for smaller players. In general, IBISWorld believes that breads that promote a healthy image will flourish though manufacturers will be “forced to accelerate innovation to keep up with changing consumer preferences.”

Protein Trend Means Sales Boost For Powder, Bar Makers

America’s demand for protein is surging, thanks to a torrent of advice from physical trainers, diet gurus and weight-loss plans; that means big business for makers of protein powders, shakes and energy bars. The boost in protein demand is also benefiting retail grocers, whose shelves are now packed with protein products, replacing space once stocked with high-fiber and low-fat products. The irony is that, even without the protein powders and bars, Americans already eat plenty of protein, experts say. A diet survey from 2007-2008 shows “men and women commonly consuming more protein than needed, sometimes by a third or more,” the AP reports.

Low Glycemic Load Diet Found To Be Better For Keeping Weight Off

Researchers at Children’s Hospital in Boston who studied the impact of three common diets on 21 overweight and obese adults over four years found that a low-fat diet seems to increase the risk of regaining weight. The researchers, curious about which diet is better at keeping weight off after initial weight loss, found the risk was less with a low-glycemic index diet, and least with a very low-carbohydrate diet. "These findings suggest that a strategy to reduce glycemic load rather than dietary fat may be advantageous for weight-loss maintenance and cardiovascular disease prevention,” the authors wrote.

Low-Carb, High-Protein Diet Poses Cardiovascular Risk For Women

A study of 44,000 Swedish women aged 30 to 49 who followed a high-protein, low-carb diet over 15 years found a slightly higher risk of cardiovascular disease, including heart disease and stroke. Figures adjusted for various control factors showed an additional four to five cases of cardiovascular diseases per 10,000 women a  year compared with those who did not regularly eat a low carbohydrate, high protein diet. The researchers acknowledged that the differences were small, but nevertheless represented a 28 percent increase in the number of cases. They said the results are disturbing in young women who may be exposed to these dietary patterns and face the excess risk for many years.

Calcium Supplements May Increase Risk Of Kidney Stones Over Time, Study Finds

U.S. researchers who studied 163 healthy, postmenopausal women (aged 57 to 85) taking various levels of vitamin D and calcium supplements daily for a year found that a significant number developed a condition associated with an increased risk of kidney stones. A third of the participants developed high urinary levels of calcium (hypercalciuria) at some time during the study. These participants had 88 episodes of high urinary calcium. Hypercalciuria has been linked to an increased risk of kidney stones in previous studies. However, no incidents of kidney stones were reported during the study.

Kids Who Cook At Home Are More Likely To Pass Up Junk Food

A survey of students in 151 schools in Alberta province found that kids who participated in cooking and meal preparation at home showed a greater preference for eating fruits and vegetables over junk food. About a third of students surveyed said they helped cook meals at least once a day, and another third said they helped one to three times a week. Only 12.4 percent stayed out of the kitchen entirely. One of the researchers said the findings show the value of getting kids interested in meal preparation in the home, and suggested there could be a role for schools as well.

Dieting Plus Exercise Reduces Risk Of Pre-Diabetes In Older Adults

Losing weight is an effective way for obese older people to prevent metabolic syndrome that leads to diabetes. But a weight loss program is even more beneficial when exercise is included, a U.S. study has found. Metabolic syndrome is a group of problems that raise the risk of type 2 diabetes and heart disease: symptoms include abdominal obesity, high blood pressure and high blood glucose. Researchers measured various metabolic markers for 93 study participants, finding that exercise alone did not lead to improvements. Dietary changes improved the measurements by 40 percent, while diet plus exercise improved markers by 70 percent.

Adding Dessert To A Low-Cal Breakfast Reduces Hunger Pangs, Keeps Off Weight

Israeli researchers report that adding a small “dessert” to the breakfast of a restricted calorie diet reduces hunger pangs during the day and helps dieters keep off lost pounds. For the eight-month study, 200 obese adults in two groups were limited to 1,600 calories a day. One group ate a 304-calorie breakfast with 10 grams of carbs and 30 grams of protein. The other group ate a 600-calorie breakfast with 45 grams of protein and 60 grams of carbs, including a small dessert consisting of chocolate, a doughnut, etc. Participants in both groups lost about 33 pounds on average during the first four months, but the low-carb group regained 22 pounds; the desert group lost another 15 pounds.

Measuring Two Appetite Hormones Before Dieting Predicts Whether Weight Will Be Regained

Scientists in Spain have determined that measuring the levels of two hormones before a dieting program is begun can accurately predict whether dieters will regain lost weight. The two hormones – leptin and ghrelin – help regulate the appetite. The researchers found the pre-diet leptin/ghrelin ratio to be two times higher among study participants who later regained weight than among those who did not. They also identified cut-off points that predicted more than 60 percent of patients who would later regain 10 percent or more of the weight they initially lost. Calculating the leptin/ghrelin ratio might help in personalizing weight-loss programs for more effective control of obesity, the researchers said.

Study Links Low Vitamin D Levels To Chronic Weight Gain

A study of more than 4,600 women aged 65 or older has found that those with low levels of vitamin D in their blood gained an average of two pounds more over five years than women whose vitamin D levels were sufficient. According to the U.S. researchers, about 80 percent of the women in the study had insufficient levels of vitamin D, a primary source of which is sunlight. The researchers said the fact that fewer people spend time outdoors in the sun could partially explain vitamin D deficiencies and chronic weight gain. They declined to recommend vitamin D supplements, however, until further studies are conducted.

Resveratrol’s Health Benefits Mimic Those Of Extensive Endurance Exercise Training

High doses of the natural antioxidant compound resveratrol improved the physical performance, heart function and muscle strength in laboratory rats, similar to the way endurance exercise improves heart and muscle performance, Canadian researchers have found. Resveratrol, found in red wine, nuts and some fruits, could be used to help patients who want to exercise but are physically incapable, the researchers said. “Our findings provide evidence that the capacity for fatty acid oxidation is augmented by the addition of resveratrol to the diet during exercise training.”

Omega-3 Supplements Reduce Inflammation Markers In Older, Overweight Individuals

U.S. researchers have found that overweight, but otherwise healthy, middle-aged and older adults who consumed omega-3 fatty acid supplements for four months had significantly lower levels of a protein in the blood that indicates the presence of inflammation associated with a variety of diseases and disorders. Omega-3 supplements lowered the protein level by ten percent and slightly lowered the level of another marker for inflammation. Participants in the study who consumed placebo oil capsules over four months, however, experienced average increases of 36 percent and 12 percent in those same markers.

Maintaining Healthy Dietary Patterns During Adolescence Prevents Obesity

Spanish researchers who studied health data and physical activity patterns from 1,978 adolescents found that some dietary habits – eating more than four scheduled meals a day, or not eating too fast – were associated with lower body fat levels, with or without free-time exercise. The researchers also noted that eating breakfast every day was especially beneficial for young men who do not exercise, because those who skipped breakfast showed higher body fat values.

Spinach Counteracts Effect Of Cooked Meat Carcinogen On microRNAs And Cancer Stem Cells

U.S. researchers who analyzed the impact of 679 micoRNAs, which were once considered “junk DNA,” found that when they go haywire they can cause abnormal gene expression that leads to cancer. For their study, the researchers traced the actions of a known carcinogen in cooked meat to its effects on microRNA and cancer stem cells, finding a direct link. On the bright side, however, they also found in animal experiments that eating spinach seems to partially offset the damaging effects of the carcinogen.

An Apple A Day – Keeps Obesity Away?

A natural substance found in apple peels known as ursolic acid not only helps increase muscle mass and strength, it also seems to reduce obesity, pre-diabetes and fatty liver disease, new U.S. research in mice has found. The scientists believe the increased muscle mass from intake of ursolic acid may explain the reduction in obesity. But they also found that ursolic acid increased brown fat, an efficient calorie burner, in mice fed a high-fat diet. Their next step is to test the effect of ursolic acid in clinical trials.

A Contrarian View Of The Health Impact Of Fructose: It Helps Control Blood Sugar In Diabetics

Scientific evidence of the dangers of fructose consumption continues to pile up, but new research takes a contrarian view that should cheer up the sugar industry. A Canadian review of 18 clinical trials involving 209 participants with either type 1 or type 2 diabetes found that fructose significantly improved blood sugar control. The improvement was similar to that achieved by an oral anti-diabetes drug. Moreover, the improvement came without adverse impact on body weight, blood pressure, uric acid (gout) or cholesterol. Participants in the trials were fed diets in which fructose was incorporated or sprinkled on foods such as cereals or coffee.

Older Women Do Not Escape Eating Disorders Associated With Teenagers, Young Adults

A U.S. study of older women – average age 59 – finds that aging does not prevent or ward off eating disorders. Among women over 50, 3.5 percent report binge eating, eight percent report purging, and more than 70 percent are trying to lose weight. Sixty-two percent of women said their weight or shape negatively affected their life. More than a quarter of the participants – 92 percent of whom were white – were obese, 29 percent were overweight, 42 percent were normal weight and two percent were underweight. The researchers urged healthcare providers to “remain alert for eating disorder symptoms and weight and shape concerns” that could harm the physical and psychological wellbeing of aging women.

Strict Control Of Glucose Levels In Diabetics Prevents Neuropathy – But With Serious Side Effects

Half of diabetics develop a disabling condition known as diabetic neuropathy, which leaves feet and legs feeling tingly, numb, painful or weak. Neuropathy can be prevented by strict control of blood sugar levels. But a U.S. and British review of six clinical studies of enhanced glucose control methods – extra insulin injections, anti-diabetic drugs, and diet changes – has found that they can be effective, there is a significant risk of adverse effects, including hypoglycemia. Further research is needed to find optimum target levels for safe treatments that will both prevent neuropathy and minimize serious side effects, according to the scientists who conducted the review.

Fish Oil Supplements Do Not Prevent Cognitive Decline In Older People

A systematic review of three British short-term clinical trials involving more than 3,500 people aged 60 or over has found that omega-3 fish oil supplements probably do not help older people retain cognitive function. The researchers acknowledged that the studies were relatively short, so the longer term effects of omega-3 fatty acids on cognitive decline and dementia need to be further explored. The trials, which were conducted for up to four years, compared the effects of omega-3 fatty acids taken in capsules or margarine to the effects of sunflower oil, olive oil or regular margarine (placebos). Participants given omega-3s did not score better in mental state examinations, or in memory and verbal fluency tests.
