The latest research, published in the journal Nutrients, explained how pecans may improve heart health and described the numerous benefits of consuming this nut. The study was executed by the team of scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Medford.
For their study, the researchers recruited 26 men and women, who were overweight or obese but otherwise healthy. The participants spent 4 weeks on one diet and then switched to another diet for the remaining 4 weeks. One of the diets was a control diet where 15% of the total calorie count were pecans. The researchers found that adding pecans to the participants’ diets improved insulin sensitivity.
Lead researcher Diane McKay, Ph.D., explains: “Pecans are naturally high in monounsaturated and polyunsaturated fats, so replacing a portion of the saturated fat in the diet with these healthier fats can explain some of the cardioprotective effect we observed.”
Researchers from Loma Linda University (LLU) Health in Beaumont, US, investigated the brainwaves triggered by eating nuts and discovered further evidence that eating nuts may boost brain strength.
For the study, a team of researchers used participants who regularly consumed various kinds of nuts such as almonds, cashews, peanuts, pecans, pistachios, and walnuts. The scientists used an EEG to measure their brain waves.
Authors conclude in their study: “This study provides objective evidence that [brain wave strength] for different brain EEG wave bands are modulated differentially by different types of nuts. These data appear to support an association of nuts’ health benefits with an increase in [delta waves] and [gamma waves].”
Eating just 2 ounces of three nuts weekly may lower the risk of cancer recurrence for patients who have been treated for stage III colon cancer according to the conclusions of a new study from the United States. Moreover, the study says that it could even halve the risk of death for such patients.
For the research, a team of scientists has analyzed the data of 826 patients with stage III colon cancer. They were asked to complete a dietary questionnaire. The risk of colon cancer recurrence was 46% lower in those patients who consumed at least 2 ounces of three nuts every week. The risk of death was 53% lower for those patients. Three nuts included cashew nuts, hazelnuts, walnuts, almonds, and pecans.
Dr. Fadelu, a leader of the study, of the Dana-Farber Cancer Institute in Boston, MA, explains: “Ultimately, we need to understand how nuts confer this protective effect, as well as possibly conduct a randomized, controlled clinical trial where diet recommendations are given at the start of the study to prove that tree nuts can reduce recurrence and death after treatment for colon cancer.”
