So, the aim of this study was to review the articles regarding the dietary fat intake and FD. We used electronic database of PubMed to search. These key words were chosen: FD, dietary fat, dyspeptic symptom, energy intake and nutrients. First, articles that their title and abstract were related to the mentioned subject were gathered. Then, full texts of related articles were selected for reading. Finally, by excluding four articles that was irrelevant to subject, 19 relevant English papers by designing clinical trial, cross-sectional, case–control, prospective cohort, and review that published from 1992 to 2012 were investigated. Anecdotally, specific food items or food groups, particularly fatty foods have been related to dyspepsia. Laboratory studies have shown that the addition of fat to a meal resulted in more symptoms of fullness, bloating, and nausea in dyspeptic patients. Studies have reported that hypersensitivity of the stomach to postprandial distension is an essential factor in the generation of dyspeptic symptoms. Small intestinal infusions of nutrients, particularly fat, exacerbate this hypersensitivity. Moreover, evidence showed that perception of gastric distension increased by lipids but not by glucose. Long chain triglycerides appear to be more potent than medium chain triglycerides in inducing symptoms of fullness, nausea, and suppression of hunger. Thus, Fatty foods may exacerbate dyspeptic symptoms. Therefore, it seems that a reduction in intake of fatty foods may useful, although this requires more evaluations. |
Basavaradhya Sahukar Shruthi, Palani Vinodhkumar, Selvamani Adv Biomed Res 2016, 5:67 (19 April 2016) DOI:10.4103/2277-9175.180636 PMID:27169098In the past decades, several ground breaking discoveries in life science were made. The completion of sequencing the human genome certainly belongs to the key tasks successfully completed, representing a true milestone in the biomedicine. The accomplishment of the complete genome also brings along a new, even more challenging task for scientists: The characterization of the human proteome. Proteomics, the main tool for proteome research, is a relatively new and extremely dynamically evolving branch of science, focused on the evaluation of gene expression at proteome level. Due to the specific properties of proteins, current proteomics deals with different issues, such as protein identification, quantification, characterization of post-translational modification, structure and function elucidation, and description of possible interactions. This field incorporates technologies that can be applied to serum and tissue in order to extract important biological information in the form of biomarkers to aid clinicians and scientists in understanding the dynamic biology of their system of interest, such as a patient with cancer. The present review article provides a detail description of proteomics and its role in cancer research. |
