In this episode we discuss different types of protein intake, the advantages and disadvantages of high protein diets, and the optimal amount of protein consumption for different age groups. As always, consult a dietitian to find healthy, affordable, and easy ways to incorporate a wide variety of protein sources, especially if you have other chronic health issues.

In this episode we explore gluten, Celiac disease, and the evidence behind utilizing gluten-free diets as a weight loss tool.

Articles/references:

    • NCGS and the benefits of a GFD are reported amongst patients with irritable bowel syndrome, inflammatory bowel disease, and non intestinal disorders such as neuropsychiatric diseases and fibromyalgia. However, no reliable biomarkers currently exist to diagnose NCGS and hence confirmatory testing can only be performed using double-blind placebo-controlled gluten-based challenges. Unfortunately, such tests are not available in routine clinical practice. Furthermore, recent novel studies have highlighted the role of other gluten-based components in contributing to the symptoms of self-reported NCGS. These include fermentable oligo, di, mono-saccharides and polyols, amylase trypsin inhibitors, and wheat germ agglutinins. Therefore, NCGS is now seen as a spectrum encompassing several biological responses and terms such as 'non coeliac wheat sensitivity' have been suggested as a wider label to define the condition.

    • And in Canada - Jamieson study: GF staples (cereals, breads, flours, pastas) contained 1.3 times more fat and less iron (by 55%), folate (by 44%) and protein (by 36%), than GC counterparts (P < 0.0001). On average, GF pastas had only 37% of the fibre in GC pastas (P < 0.0001). Notably, GF and GC flours were equivalent in nutrient content. Despite GF and GC flours having similar nutritional content, the vast majority of the processed GF foods fell short in key nutrients.

The ketogenic diet has been prescribed medically as a regimen for children with refractory seizures. It has since gained popularity recently as a weight loss strategy. This diet is important to understand because of its effect on overall body physiology in order to best counsel patients, especially as patients may be bringing it up more frequently as a current "fad diet"!

Although easy to overlook, beverage consumption (specifically, sugar sweetened beverages) can have profound effects on a person's health. Here, we discuss how to advise patients and what the research says as far as beverage consumption for all ages.

The European Society for Paediatric Gastroenterology, Hepatology, and Nutrition Committee on Nutrition provides similar recommendations [53]. Studies evaluating added sugars in children are limited [25]. Pending additional information, these consensus guidelines seem reasonable.This limit is based upon the recommendation in the 2005 Dietary Guidelines for Americans to limit discretionary kilocalories (ie, those available for consumption as added sugars or solid fats after essential daily nutrient requirements are met) to 6 to 10 percent of total daily energy intake [57]; the 2015 Dietary Guidelines suggest limiting added sugars to <10 percent of total daily energy intake [28]
