New Gadget Measures Acetone Expelled From Lungs When Fat Is Burned

Japanese scientists have developed a pocket-sized breathalyzer that measures -- not alcohol -- in the breath, but acetone, an indicator of fat metabolism. Acetone is expelled through the lungs when fat is broken down. The new device can detect acetone at concentration sin  the range of 0.2 to 50 parts-per-million. It weighs only 4.5 ounces and uses two AA batteries. It uses a pressure sensor to detect exhaled breath and two types of semiconductor-based sensors to detect acetone. The researchers believe their device will be useful in estimating fat loss from changes in breath acetone concentrations and determining whether diets are really working.

Consumers Should Be Careful About Eating Seafood, But Should Not Ignore Its Health Benefits

Consumers should be concerned about whether the seafood they eat is safe, but nutritionists say the health value of seafood far outweighs the risks. Eating two 3- to 5-ounce servings a week of fish such as salmon, oysters and rainbow trout provide an average of 250 mg/day of omega-3 fatty acids, which have been associated with a decreased risk of cardiovascular disease. A professor at the University of Southern California said consumers can safely eat 12 ounces of a variety of cooked seafood a week, so long as they heed local seafood advisories “and limit their intake of large, predatory fish like shark”.

Nuts – Especially Walnuts – Significantly Reduce Risks Of Cardiovascular And Cancer Death

Researchers in Spain who compared the effect of a Mediterranean diet (with extra virgin olive oil and nuts) to a simply low-fat diet among 7,000 older people found that people who eat nuts, especially walnuts, tend to live longer. Those who followed the Mediterranean diet, and ate nuts at least three times a week, had a lower BMI and smaller waist, were less likely to smoke and more likely to be physically active. Nut eaters were less likely to have type 2 diabetes and hypertension, and had a 39 percent lower mortality risk (walnut eaters had a 45 percent lower risk). Those who ate three servings (one ounce per serving) a week of nuts reduced the chances of death due to cardiovascular disease by 55 percent and to cancer by 40 percent.

Healthy Snacks Help Control Appetite, Lower Caloric Intake

Dieters who can control their hunger can reduce overall energy intake during the day and lose weight, according to a British nutrition research manager. A good way to control appetite is to eat healthy snacks between meals, especially peanuts, nuts and other high-fiber snacks. In a recent study, participants who regularly consumed almonds as a mid-morning snack said they felt fuller and ended up eating less for lunch and dinner. Another study found that participants lowered their daily caloric intake after eating a snack of cereal each day.

Scientific Evidence That Cranberries Do Inhibit The Bacterium Associated With UTIs

Canadian researchers report that in lab experiments cranberry powder inhibits the swarming and swimming activity ability of bacterium frequently implicated in complicated urinary tract infections (UTIs). The study also shows that higher concentrations of cranberry powder reduce the bacteria's production of urease, an enzyme that contributes to the virulence of infections. The findings may point the way to developing protection against urinary tract and other infections. In another study, the scientists find that cranberry derivatives could someday be used to prevent bacterial colonization in medical devices such as catheters.

Sixteen Percent Of Imported Hot Sauces Exceed Safe Levels Of Lead Content

Researchers at the University of Las Vegas who analyzed 25 bottles of hot sauce imported from Mexico and South America found that four brands – 16 percent – exceed 0.1 parts-per-million (ppm) lead content, which is the current standard set by the FDA for unsafe levels of lead in candy. The brands were all from Mexico, but from different manufacturers. Hot sauce as a regular part of a child’s diet, especially in Hispanic cultures, could contribute to unsafe levels of lead exposure. The researchers called for more rigorous screening of hot sauces imported from Mexico, as well as an appropriate FDA standard for dangerous lead levels in hot sauce.

Mom Was Right: Chew Your Food Thoroughly To Get The Most Nutrient Benefits

It’s official: what mom said about taking the time to chew your food thoroughly is backed by science. According to a U.S. researcher who conducted a study on chewing and digesting almonds, the smaller the particle size the greater the “bioaccessibility” of the energy from the food being consumed. For the study, participants chewed almonds 10 times, 25 times or 40 times. Researchers measured their fecal fat and energy lost by the number of chews. The fewer the chews, the greater the number of larger particles were eliminated. With more chews, smaller particles were more readily absorbed into the system.

Diet Poor In Omega-3s Leads To Health Problems Among Teens And Their Parents

New U.S. research finds that teens especially – but also their parents – who eat fewer foods containing omega-3 fatty acids are more prone to anxiety and hyperactivity, as well as impaired memory and cognition. Omega-3 fatty acids are found in oily fish like salmon and sardines, eggs, and meat from grass-fed livestock. The researchers, whose study was conducted among multiple generations of lab animals, said the health problems occur not just in the teens themselves but also in parents born in the 1960s and 1970s, when omega-3-deficient oils like corn and soy oil became prevalent, and farm animals began eating grain instead of grass.

For Peak Performance, Athletes Should Eat A High-Fiber, Low-Fat Diet While Training

Too many athletes are pushed into fad diets or diets that restrict calorie intake too much in a way that is unhealthy and unsustainable, according to a U.S. researcher who reviewed scientific literature. Instead, to maintain a healthy weight and remain performance-ready, athletes need to adopt a low-energy-dense diet that includes a lot of fruits, vegetables, whole grains, lean meat, fish, and low-fat dairy. Sugary beverages like soda and alcohols should be avoided. Half of a plate of food should contain fruits and veggies, and processed food should be avoided. Lastly, opt for the food over the drink: instead of drinking orange juice, eat an orange. It has more fiber, and fills you up more.

Eating Breakfast Is Important For Heart Health

Missing breakfast in the morning, or eating a meal late at night, can cause metabolic effects that lead to coronary heart disease, according to a U.S. study. Researchers analyzed data from a food frequency questionnaire, tracking health outcomes from 1992 to 2008, on nearly 27,000 males aged 45 to 82.  Men who reported they skipped breakfast had a 27 percent higher risk of heart attack or death from coronary heart disease than those who reported they didn't. Men who reported eating late at night (eating after going to bed) had a 55 percent higher coronary heart disease risk than those who didn't. Skipping breakfast may lead to one or more heart disease risk factors, including obesity, high blood pressure, high cholesterol and diabetes.

Antioxidants May Block The Benefits Of Good Bodily Stress, Like Exercise

The natural antioxidant resveratrol, found in red grapes and other plants and available as a dietary supplement, has been touted as an anti-aging compound. But new research finds that, in older men especially, eating a diet rich in antioxidants may actually counteract many of the health benefits derived from exercise, including lower blood pressure and cholesterol. The researchers suggest that antioxidants are not a panacea: some oxidative stress is necessary for the body to function effectively. Too many antioxidants may block healthy adaptations to stress, including beneficial exercise stress.

Eating Eggs Does Not Increase Risk Of Heart Disease Among Adolescents

A European study conducted in nine countries found that adolescents who ate larger amounts of eggs did not have higher serum cholesterol nor worse cardiovascular health, regardless of their levels of physical activity. Health experts have long followed the 1973 American Heart Association recommendation that egg consumption be limited to three a week, because of the higher cholesterol levels. But most foods rich in cholesterol are usually also rich in saturated fats. A medium-size egg contains 200 milligrams of cholesterol but has more unsaturated fats than saturated fats and only 70 calories.

More Frequent Exercise Associated With Lower Risk Of Stroke Among Men

A U.S. study involving 27,000 stroke-free blacks and white older than 45  found that physical inactivity, which was reported a 33 percent of participants, was associated with a 20 percent greater risk of stroke. Men who exercised four or more times a week had a lower stroke risk, but the link between exercise frequency  and stroke among women was less clear. The researchers acknowledged that a limitation of the study was the self-reporting aspect. Results based on self-reported levels of physical activity may not reflect the truth.

There Are Numerous Sources Of Key Nutrients For Vegetarian Athletes

Vegetarian athletes have to find ways to boost macronutrient levels in their diet, without consuming animal-based foods. The good news is that predominantly or exclusively plant-based foods do indeed provide those needed nutrients, . Eating orange/yellow and green leafy vegetables, fruits, fortified breakfast cereals, soy drinks, nuts and milk products (for vegetarians who consume dairy) can provide the iron, creatine, zinc, vitamin B12, vitamin D and calcium usually provided by animal foods. The formula for acceptable macronutrient distribution for all athletes, including marathon runners, is carbs (45-65 percent), fat (20-35 percent) and protein (10-35 percent).

Mood Disorders Can Be Improved With Vitamins, Minerals

A Canadian researcher who studied 97 adults diagnosed with mood disorders found that those who took more vitamins and minerals over three days showed significantly improved mental functioning. Bonnie Kaplan said vitamin and mineral supplements could be an alternative to increasing psychiatric medicines for relief of symptoms of anxiety and depression. Another researcher noted that 5-Hydroxytryptophan (5 HTP), vitamins B and D, as well as ginkgo biloba and omega 3 supplements have been known to enhance mood.

Study Finds Significant Increase In Blood Pressure Levels Among Children, Adolescents

U.S. researchers who analyzed health data from 3,200 children and adolescents found in two time periods (1988-1994 and 1999-2008) found that the risk of high blood pressure rose 27 percent in 13 years. The researchers suggested that the elevated blood pressure readings were probably due to high body mass, larger waistlines and excess sodium consumption. The elevated readings did not establish that the children were hypertensive, only that the risk of hypertension had risen significantly. High blood pressure is a risk factor for stroke, heart disease and kidney failure, accounting for about 350,000 preventable deaths a year in the United States.
