In Ankara, Turkey, scientists at Hacettepe University’s Department of Food Engineering compared 18 ancients wheats (12 emmer, 6 einkorn) with 2 modern bread wheats, to assess their total phenolics and flavonoids, phenolic acids, lutein, total yellow pigment, and total radical scavenging capacities. Results showed “remarkably higher total antioxidant activity” in emmer varieties, and “quite high levels of lutein” in the einkorn samples. In conclusion, the findings were considered to be key to “breeding wheat varieties for higher concentration and better composition of health-beneficial phytochemicals.”

It is known that the healthfulness of the Latino diet deteriorates during the acculturation process, as Latino immigrants adopt the habits of their new culture.  A meta-analysis was conducted to review the literature available on the effect of acculturation on the Latino diet.  The analysis concluded that there was no relationship between acculturation and dietary fat intake or percent energy from fat, despite evidence that fat-related behaviors seem to differ between those who are less or more acculturated.  It also concluded that less acculturated Latin Americans consumed more fruit, rice, beans, and less sugar and sugar-sweetened beverages than more acculturated Latin Americans.

Advanced glycation endproducts (AGEs) are increasingly implicated in the complications of diabetes. A study from the University of Georgia Neutraceutical Research Libraries showed that sorghum brans with a high phenolic content and high anti-oxidant properties inhibit protein glycation, whereas wheat, rice or oat bran, and low-phenolic sorghum bran did not. These results suggest that “certain varieties of  sorghum bran may affect critical biological processes that are important in diabetes and insulin resistance.”

After following 72,113 women for almost twenty years, researchers at the Harvard School of Public Health concluded that eating a “prudent” diet rich in vegetables, fruits, legumes, whole grains, fish and poultry may reduce the risk for cardiovascular disease and for overall mortality. The study divided the women into two groups, those eating the “prudent” diet and those consuming a typical “Western” diet with high levels of red meat, processed meat, refined grains, french fries, and sweet or desserts.

Nigeria is facing an increasing prevalence of obesity, with a particularly strong occurrence in populations with hypertension and diabetes. A Nigerian study of these increases says that the rise of obesity rates can easily be attributed to rapid unplanned urbanization, change from local dietary pattern to western style diet which is driven by the proliferation of fast food outlets in major cities across the country. This study makes that connection.

Scientists at the Swedish University of Agricultural Sciences in Uppsala decided to investigate whether whole grains keep people full and satisfied longer than refined grains – and whether specific types of whole grains are more satisfying than others. Working with 22 healthy adults, they fed their subjects either rye porridge or refined wheat bread for breakfast and then whole wheat pasta or refined wheat pasta for lunch. In both cases, the two options offered equal amounts of energy (calories). They found that the two pastas varied little in their subsequent effects on appetite, but that the rye porridge had “prolonged satiating properties up to 8 hours after consumption, compared to refined wheat bread.” (However, even though the rye breakfast made subjects feel full longer, it did not diminish subsequent food consumption.)

Researchers at Loma Linda University investigated a cohort of peri- and post-menopausal women over a period of 25 years to compare incidences of wrist fracture with diet type. They found that vegetarians who consumed low amounts of protein suffered the most wrist fractures. However, increasing levels of plant-based protein foods decreased risk by 68% and increasing meat intake decreased risk by 80%. These findings suggest that dietary protein plays a significant role in bone health among middle-aged and elderly females.

Eating an average of 2.5 servings of whole grain foods each day can lower your risk of cardiovascular disease by almost one-quarter. That’s the finding of a seven-study meta-analysis of 285,000 men and women led by Philip Mellen of Wake Forest University. In light of this evidence, Mellen said, policy-makers, scientists and clinicians should “redouble efforts” to get people to eat more whole grains.

At the University of Nebraska, researchers examined data from the 1999-2002 National Health and Nutrition Examination Survey (NHANES) to learn whether popcorn consumption was associated with different dietary intake patterns. They found that, on average, those who regularly ate popcorn consumed 250% more whole grain overall (2.5 vs 0.7 servings per day), and about 22% more fiber (18.1g vs 14.9g per day). The popcorn-eaters also consumed fewer meat servings and more carbohydrates.

Scientists at the University of Alberta baked whole wheat bread using the same cultivar of hard red spring wheat grown both conventionally and organically. They then asked 384 consumers to rate the taste – once, with unlabeled samples and no knowledge of the different origins, and again, after the breads had been labeled and the different growing conditions described. Consumers rated the taste of the organic bread higher both in the blind test and the informed test. Their ratings were unaffected by information on the environmental benefits of organic farming, but they liked the organic bread even more after learning of the potential health benefits of organically-grown foods.

At the University of Kuopio in Finland, scientists assigned a group of 47 adults with metabolic syndrome to one of two different 12-week diets. The first group ate a diet with oat, wheat bread and potato (high post-meal insulin response) and the second group ate a diet with rye bread and pasta (low post-meal insulin response). The researchers found that the rye/pasta group showed less inflammation than the oat/wheat/potato group. Since inflammation may raise the risk of type 2 diabetes, the researchers concluded that choosing cereal foods wisely may be important to reduce diabetes risk, especially in those who already have metabolic syndrome.

Researchers at the University of Vienna compared the ratio of omega-6:omega-3 polyunsaturated fatty acids (PUFAs) in omnivores, vegetarians, vegans, and semi-omnivores to assess essential fatty acid status as it relates to diet. They found that vegans had the highest average ratio of omega-6:omega3 PUFAs. High ratios are believed to be pro-inflammatory and may also contribute to tissue decline and neurological dysfunction. While the authors emphasize the need for further research on this topic, they also urge vegetarians and especially vegans to increase their intakes of omega-3 fatty acids from non-animal sources such as algae.
