Effects of Graded Dietary Levels of Spirulina maxima on Vitamins A and E in Male Rats

摘要: The effects of ingesting the alga Spirulina maxima on storage and utilization vitamins A E were investigated by feeding diets containing 0, 2.7, 10.7, 18.7 26.7% S. to male rats for 6 wk. All contained 18% protein, which was contributed or casein a mixture them. Growth results indicated that did not utilize as well control diet (0% maxima) when levels 10.7% more diet. ingestion caused significant increase in dry matter chloroform-extractable crude fat feces. low level 2.7% reduction plasma, liver heart alpha-tocopherol levels. concentrations these tissues showed marked decline with diet, followed lesser at higher Liver retinoid increased added suggesting conversion naturally occurring carotenoids vitamin A. However, plasma retinol decreased fed more. These data demonstrate can significantly alter E.
