The purpose of this paper was to investigate the impact of specific carbohydrate restriction (polysaccharides and disaccharides) in the form of the specific carbohydrate diet (SCD) in treating irritable bowel syndrome (IBS).

A female patient diagnosed with diarrhea predominant IBS was assigned to the SCD for six months. The diet occurred in phases and was advanced based on the individual’s tolerance level under the guidance of a registered dietitian. Quality of life was measured by a pre- and post-IBS severity score questionnaire. Gastrointestinal symptoms were measured by self-assessment of IBS symptoms using a seven-point Likert-like scale, with −3 = substantially worse to +3 = substantially better. Probiotics were consumed throughout the duration of the study.

The quality of life severity score significantly improved from a severity of 315 (with 500 being the most severe) to 15. The initial symptoms from the first day on the diet compared to the total period for bloating, abdominal pain/discomfort, flatulence/wind, diarrhea, bowel urgency, stool consistency, stool frequency, energy levels, incomplete evacuation and abdominal rumbling were improved significantly (p < 0.0005). The SCD diet significantly improved the quality of life and IBS symptoms in a female patient with IBS-diarrhea.

This study is the first of its kind to evaluate the efficacy of the SCD to treat IBS. The SCD should be considered a therapeutic option to treating IBS after fermentable carbohydrate restriction.

The purpose of this study is to compare the oxidative stability of non‐hydrogenated cottonseed oil with that of the partially hydrogenated oils commonly used as a deep‐fat frying medium by the restaurant industry when used to prepare French fries in order to reduce trans‐fatty acids.

Stability characteristics of non‐hydrogenated cottonseed oil and two hydrogenated oils, canola and soybean, were evaluated in deep‐fat frying applications. French fries were analyzed for total polar compounds, and the oils were analyzed for iodine, peroxide, p‐anisidine and totox values, and free fatty acids.

Canola and soybean oil had significantly lower iodine values than cottonseed oil. Free fatty acid values were not significantly different among the oils (0.256 per cent oleic acid). Initially cottonseed oil had higher peroxide, p‐anisidine, and totox values compared with canola and soybean oil. However, as days of frying increased, values trended closer together. Total polar compounds were similar. All oil types were comparable in terms of their stability characteristics under the conditions used in this study.

Research with additional food product and under more stressful conditions would be beneficial.

Hydrogenation increases trans‐fatty acid content. Consumption of trans‐fatty acids has been associated with increased risk of heart disease. Non‐hydrogenated cottonseed oil may be a viable alternative to popular hydrogenated oils currently used in the restaurant setting.

Restaurants are being pressured by health officials to choose healthier oil. This research article can help restaurants make an informed choice.
