多种鱼的膳食疗方(1)

鱼是人人爱吃的水产美食,也是众多百姓家庭餐桌上常见的营养佳肴。但鱼的种类繁多,且不同的鱼有不同的营养价值、保健功能。下面介绍14种常见鱼的营养价值及膳食疗方.

地黄膳食疗众疾

一、生地黄粥 生地黄汁约50克(或用干地黄60克),粳米100克,生姜2片。用新鲜生地黄适量,洗净后切段,每次榨取生地黄汁约50克,或用干地黄60克,煎取浓汁。先用粳米加水煮粥,然后加入地黄汁和生姜。煮成稀粥食用。本方清热生津,凉血止血。适用于热病后期,阴液耗伤、低热不退、劳热、骨蒸或高热心烦、口干作渴、口鼻出血。

菊花入膳 食疗俱佳

鲜花入膳已成一种时尚，其实花卉入膳在我国有着悠久历史，而中国传统名花菊花更为我国人民历来所喜爱，尤其是我国人民信奉某些中药能延年益寿，对菊花有疏风、清热、明目、解毒等保健功能更是情有独钟，故菊花一直被称为“延寿客”。

Effect of dietary genistein on growth performance,digestive enzyme activity,and body composition of Nile tilapia Oreochromis niloticus

An 8-week feeding experiment was performed to evaluate the effect of dietary genistein on growth performance,body composition,and digestive enzymes activity of juvenile Nile tilapia(Oreochromis niloticus).Four isonitrogenous and isoenergetic diets were formulated containing four graded supplements of genistein:0,30,300,and 3 000 μg/g.Each diet was randomly assigned in triplicate to tanks stocked with 15 juvenile tilapia(10.47±1.24 g).The results show that 30 and 300 μg/gdietary genistein had no significant effect on growth performance of Nile tilapia,but the higher level of genistein(3 000 μg/g)significantly depressed the final body weight and specific growth rate.There was no significant difference in survival rate,feed intake,feed efficiency ratio or whole body composition among all dietary treatments.An assay of digestive enzymes showed that the diet containing 3 000 μg/ggenistein decreased stomach and hepatopancreas protease activity,and amylase activity in the liver and intestine,while a dietary level of300 μg/g genistein depressed stomach protease and intestine amylase activities.However,no significant difference in stomach amylase activity was found among dietary treatments.Overall,the results of the present study indicate that a high level of dietary genistein(3 000 μg/g,or above) would significantly reduce the growth of Nile tilapia,partly because of its inhibitory effect on the activity of major digestive enzymes.Accordingly,the detrimental effects of genistein,as found in soybean products,should not be ignored when applied as an alternative ingredient source in aquaculture.

Efficacy observation of auricular point sticking in combination with a healthy diet for simple obesity in children

Objective To observe the clinical efficacy of combining auricular point sticking and a healthy diet to treat simple obesity in children aged 6–9 years old.Methods A total of 190 eligible obese kids were divided into an observation group and a control group using the random number table method,with 95 cases in each group.The observation group was intervened by auricular point sticking plus guide on a healthy diet,while the control group was only provided with the guide on a healthy diet.The therapeutic efficacy was observed after intervention for three consecutive months,as well as the changes in body mass(BM),body mass index(BMI),waist circumference(WC),hip circumference(HC),and subcutaneous fat thickness.Results After the 3-month intervention,the total effective rate was 91.6%in the observation group,versus 74.7%in the control group,and the between-group difference was statistically significant(P<0.01);in both groups,the BM,BMI,WC,HC,and subcutaneous fat thickness all decreased significantly(P<0.05),and were lower in the observation group than in the control group,showing statistical significance(P<0.05).Conclusion Auricular point sticking plus a healthy diet is safe and effective in treating simple obesity in children,producing more significant efficacy than healthy diet intervention alone.

Effect of acupuncture on serum PYY and nesfatin-1 in obese patients with insulin resistance

Objective To observe the effect of acupuncture on serum peptide YY(PYY)and nesfatin-1 in obese patients with insulin resistance.Methods Ninety-eight obese patients with insulin resistance were divided into a control group and an observation group by the random number table method,with 49 cases in each group.The control group received exercise and dietary interventions,and the observation group received additional acupuncture treatment to the exercise and dietary interventions.The body mass index(BMI),body fat percentage,fasting insulin(FINS),fasting plasma glucose(FPG),homeostasis model assessment for insulin resistance(HOMA-IR),triglyceride(TG),total cholesterol(TC),and serum PYY and nesfatin-1 levels were compared before and after treatment.The efficacy was evaluated after treatment.Results The total effective rate was significantly higher in the observation group than in the control group(P<0.05).After treatment,the BMI,body fat percentage,and serum TG and TC levels decreased significantly in both groups(P<0.05),and were significantly lower in the observation group than those in the control group(P<0.05).The FINS,FPG,HOMA-IR,and serum PYY and nesfatin-1 levels of the control group were not significantly changed after treatment(P>0.05).The FINS,FPG and HOMA-IR of the observation group decreased significantly after treatment(P<0.05),and were lower than those in the control group(P<0.05).The serum PYY and nesfatin-1 levels of the observation group increased significantly after treatment(P<0.05),and were higher than those in the control group(P<0.05).Conclusion Based on exercise and dietary interventions,acupuncture is effective for obese patients with insulin resistance.It can reduce the BMI,body fat percentage,blood lipids,blood glucose,and serum insulin levels and improve insulin resistance.The action may be associated with the up-regulation of serum PYY and nesfatin-1.
