German researchers who compared the amounts and bioavailability of nutrients in oranges and processed orange juice found that the juice might actually be better for you. True, the production of pasteurized orange juice slightly lowers the levels of carotenoids, flavonoids and vitamin C. But it significantly boosts bioaccessibility (the ability of the body to absorb and use the nutrients.) In fact, though juicing oranges dramatically cuts flavonoids, the nutrients that are left are much more bioaccessible than those in orange segments.

The genes of participants in a Finnish clinical study, whose diet comprised whole grains, fruits, vegetables, canola oil, low-fat dairy and fish – the so-called “Nordic diet”, were much less likely to express inflammation factors in subcutaneous fat tissue, even without weight loss. Scientists believe the adverse health effects of being overweight or obese are caused by inflamed fat tissue. The study suggests that the Nordic diet can be used to fight low-grade inflammation in fat that is linked to a number of chronic diseases.

A U.S. clinical trial that tested the relationship between avocados and health found that eating just one avocado a day can have significant heart-health benefits. When included in a heart healthy, cholesterol-lowering moderate-fat diet, avocados lowered low-density lipoprotein (“bad cholesterol”) levels in otherwise healthy overweight and obese individuals. Avocado eaters also had lower total cholesterol and lower triglycerides (fat) in their blood. Avocados are usually eaten in guacamole, but they can also be eaten with salads, vegetables, sandwiches, lean protein foods (like chicken or fish) or even whole, researchers said.

A mouse study has found that the fructose-glucose mix typical of high fructose corn syrup (HFCS) in processed foods is more toxic than the fructose-glucose mix in common table sugar used in baking. The main reason is that fructose and glucose in HFCS exist as separate molecules (monosaccharides), but combine into disaccharides in table sugar. The U.S. study compared two groups of mice fed a healthy diet with 25 percent calories from processed sugars: fructose-glucose monosaccharides like those in HFCS, or sucrose. Female mice on the fructose-glucose diet had death rates 1.87 times higher than females on the sucrose diet. They also produced 26.4 percent fewer offspring.

A Harvard University study that recorded the health histories of girls aged 9 to 14, tracking their consumption of sugary drinks, reports that those who consumed the most on average started their periods earlier than others. The study, conducted between 1996 and 2001, shows that girls who drank more than 1.5 servings a day began to menstruate 2.7 months earlier than their peers. The researchers said a main concern is childhood obesity, but early menstruation has also been associated with breast cancer. A 2.7 month decrease in age at onset of menstruation “likely has a modest impact on breast cancer risk”.

A Cornell Medical College study shows that a lack of vitamin A -- found in meat, fish, poultry, dairy foods, fruits and vegetables – may be a key factor in the development of type 2 diabetes. Vitamin A helps give rise to beta cells in the pancreas that produce the blood sugar-regulating hormone insulin. In a mouse study, the researchers found that a vitamin A deficiency spurred the death of beta cells, inhibiting insulin production. Insulin metabolizes sugars that come from food. The researchers suggest the possibility that a synthetic form of vitamin A might reverse the effects of type 2 diabetes. They hope to test the idea in preclinical and clinical studies.

A study that analyzed questionnaire answers from 7,443 children up to age 11, and 6,447 adolescents to age 19, verified what parents already knew: kids love pizza, and they eat way too much of it. Twenty-two percent of kids between the ages of 6 and 19 eat pizza on any given say, compared to 13 percent of Americans overall. (The only foods more popular than pizza are cake, cookies and doughnuts.) The problem is that pizza adds 408 calories, three grams of fat and 134 more milligrams of salt to a youngster’s diet, and 624 calories, five grams of fat and 484 milligrams of salt to a teen’s diet. The researchers said the negative impact of pizza on young peoples’ diets is about the same as that of sugary drinks.

A Nielsen global survey finds that the younger (under 20) generation – dubbed “Z” – is willing to put their money where their mouth is when it comes to healthful eating. Forty-one percent said they would pay a premium for healthful foods, compared to 32 percent of Millennials (ages 21 to 34) and 21 percent of Boomers (51 to 69). The message to food manufacturers is clear: think healthy, according to a Nielsen exec. "Companies that have a clear health orientation to their products will benefit most," says James Russo, who led the study.
