<p>Syftet med denna litteraturstudie var att via litteraturen beskriva nutritionens betydelse för sårläkning. Studien genomfördes som en deskriptiv litteraturstudie där metoden bestod av att söka vetenskapliga artiklar i databaserna Medline, Cinahl och Academic Search Elite. Sjutton artiklar valdes ut. Resultatet visade att patienter med bensår eller trycksår i många fall inte når upp till de näringsrekommendationer som finns. Det visade sig vara vanligt att dessa patienter ligger vid gränsen för att vara undernärda. Det upptäcktes att det är sällan som kostintaget täcker energibehovet. Framför allt var zinknivåerna genomgående väldigt låga och det visar även att det är brist på en hel del andra ämnen. Ämnen som visat sig speciellt fördelaktiga för sårläkning är protein, vitamin C, zink samt arginin. För patienter med brännskador däremot har det visat sig att saltet ornithine α-ketoglutarate minskar proteinkatabolismen samt förbättrar proteinsyntesen, vilket är en förutsättning för sårläkning. Slutsatsen med föreliggande studie var att nutritionen är viktig och kan ha en avgörande betydelse för sårläkning.</p> / <p>The purpose with this literature study was that through literature describe the nutrition’s significance for healing wounds. The study was made as a descriptive literature study where the method was conducted by searching scientific articles in the databases Medline, Cinahl and Academic Search Elite. Seventeen articles were chosen. The result showed that patients with leg ulcers or pressure sores in many cases don’t attain the recommendations for nutrition that are available. It showed that it is normal that these patients are on the border of being undernourished. It was discovered that the nutrient intake rarely covers the energy needs. Above all the zinc levels were throughout very low and that shows that there is also lack of some other substances. The substances that have been shown especially good for healing wounds are protein, vitamin C, zinc and arginine. However, for patients with burn injuries the salt ornithine α-ketoglutarate has been shown to reduce protein catabolism and also improve protein synthesis, which are essential to healing wounds. The conclusion from this study was that nutrition may be an important but also a determining factor to healing wounds.</p>

The primary objective of this study was to determine if the intake of omega-3 fatty acids (O3FA), from self-selected foods and supplements, was associated with a reduction in muscle soreness in collegiate rowers. Several groups of collegiate rowers were identified as potential subjects and, using an IRB-approved protocol, 61 volunteers from this subject pool agreed to participate in the study. At the end of the first week of fall practice, subjects were asked to provide information on age, weight, height, ethnicity, rowing level, sun exposure, exercise regimen, pre- and peak-soreness and exertion levels, hydration status, and food/supplement intake. A Talag scale was used to determine the severity of muscle soreness, and a modified Borg scale was used to determine the exertion intensity level. A food frequency questionnaire using a 10-point Likert scale was used to assess food and supplement intake, with a special focus on O3FA. Subjects with a higher intake of EPA/DHA rich bottled supplemental fish oil, taken by spoon, had significantly higher soreness levels than those with lower intakes (p = 0.028). Higher soreness was also significantly associated with higher intake of EPA/DHA rich fish oil capsules (p < 0.001). Lower soreness was significantly associated with higher fruit intake (p = 0.030). These findings suggest that high intakes of O3FA from fish oils, regardless of liquid or capsule form, may be contraindicated for collegiate rowers wishing to reduce muscle soreness. Recommending fruit intake may be warranted for rowers wishing to reduce muscle soreness.
