by Ashley Jordan Ferira, PhD, RDN Vitamin D is essential- it helps absorb calcium, supports nervous and muscle tissue, and the immune system. Compared to normal-weight counterparts, vitamin D deficiency is more prevalent in those with obesity. In the US over one-third of adults meet obesity criteria.1 A study in The Journal of Clinical Endocrinology and Metabolism2 examined cellular mechanisms of vitamin D trafficking in metabolically dysfunctional adipose tissue as compared to normal adipocytes in conjunction with a vitamin D supplementation intervention in…

by Ashley Jordan Ferira, PhD, RDN The latest findings from the landmark Swedish Obese Subjects (SOS) trial demonstrate that bariatric surgery significantly reduces the incidence of female-specific cancers, with the most pronounced cancer risk reductions seen for endometrial cancer and in women with high insulin levels pre-surgery.1-2 The health and economic burdens of obesity in the US, and globally, are immense. Based on the latest 2015-2016 National Health and Nutrition Examination Survey findings from the Centers for Disease Control and…

by Ashley Jordan Ferira, PhD, RDN Recent research from three well-known cohorts, The Nurses’ Health Study (NHS), NHS2 and Health Professionals’ Follow-Up Study (HPFS), reveals that higher magnesium intake is associated with lower risk of type 2 diabetes (T2D), particularly in diets with poor carbohydrate quality.1 Green leafy vegetables, unrefined whole grains, and nuts are richest in magnesium, while meats and milk contain a moderate amount.2 Refined foods, like carbohydrates (carb), are poor sources of magnesium. Diets with poor carb quality are characterized by…

by Ashley Jordan Ferira, PhD, RDN Cellular oxidative stress, the balance between pro-oxidants and antioxidants, may contribute to the pathogenesis of chronic diseases.1 A nutrient-dense dietary pattern, particularly one containing fruits and vegetables, whole grains, nuts, and legumes, confers antioxidant activity in the body. This is important because prior research has demonstrated that increasing the amount of antioxidants in the diet is associated with reductions in cardiovascular disease (CVD), cancer and all-cause mortality.1 However, data linking antioxidant intake and effects…

by Ashley Jordan Ferira, PhD, RDN The global burden of diabetes is staggering, with an estimated 422 million adults living with the chronic disease.1 This prevalence has almost doubled since 1980 alongside the rise in obesity and has been dubbed the “diabesity” phenomenon.1 Diabetes and its myriad comorbidities (heart attack, stroke, kidney disease, nerve damage, limb amputation, vision loss, and pregnancy complications) translate into substantial economic losses to the person affected by the disease, health systems and national economies.1 Effective…

by Ashley Jordan Ferira, PhD, RDN Updated clinical practice guidelines from the 2017 American Heart Association (AHA) Scientific Sessions and co-published in Hypertension1 and the Journal of the American College of Cardiology2 by the American College of Cardiology (ACC) and AHA, revealed a new blood pressure (BP) classification system and updated hypertension (HTN) treatment recommendations, with a clear emphasis on lifestyle approaches. How will these guidelines affect clinical decision-making? These updated, more conservative ACC/AHA criteria will translate into millions of newly diagnosed patients with HTN, shifting many…

by Ashley Jordan Ferira, PhD, RDN You may have heard that many Americans are not getting enough vitamin D, calcium, potassium, etc. from their diet. But do you think about omega-3s as a nutrient gap? You should. Research from the National Health and Nutrition Examination Survey (NHANES) demonstrates that> 90% of Americans are not meeting recommendations for omega-3 intake,with key differences observed in age, sex, and ethnicity subgroups.1 Although the cardiovascular benefits of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have…

by Ashley Jordan Ferira, PhD, RDN With over 70% of US adults overweight or obese,1 weight loss methods that are effective and sustainable over the long-term are critically needed. A National Institutes of Health (NIH) study led by Kevin D. Hall, PhD investigated how physical activity (PA) and energy intake (EI) impacted long-term weight loss in participants from “The Biggest Loser” TV competition.2 “The Biggest Loser” is a televised weight loss competition involving an intensive diet and exercise program (30…

by Ashley Jordan Ferira, PhD, RDN A food fortification trial demonstrated that 600 IU of daily vitamin D3 had a significantly greater impact than 600 IU of daily vitamin D2 in elevating serum blood levels of 25-hydroxyvitamin D [25(OH)D].1-2 Vitamin D is essential for skeletal health and many emerging extraskeletal physiological processes, but remains one of the most common micronutrient dietary gaps, resulting in widespread hypovitaminosis D globally. Understanding how much vitamin D the body needs daily, in what form, and from what sources…

by Ashley Jordan Ferira, PhD, RDN Colorectal cancer (CRC) is the third leading cause of cancer-related death for men and women in the US.1 Chronic inflammation contributes to cancer development.2 Pro-inflammatory conditions, such as obesity and inflammatory bowel disease, have been associated with CRC risk.3-4 It is plausible that a dietary pattern that induces more inflammation could impact CRC risk. The relationship between dietary inflammatory potential and CRC risk was investigated by Dr. Frank Hu of Harvard University and his colleagues, evaluating data…
