Abstract Nutsare a natural healthy food product. They have a high nutritional value because of their fiber, protein, vitamin and mineral content. Another advantage to the health of nuts is because of their favorable fatty acid composition, 80-90% of the fats being unsaturated fats. Unsaturated fats appear to be relevant in relation to the prevention of cardiovascular diseases. Also, nuts can be helping to regulate body weight, protect against typeΠ diabetes, healthy for kidney, blood Pressure Control. Yoghurt is one of the oldest most fermented dairy milk products and the most popular of these products in Egypt and worldwide. It has a sharp refreshing acid taste and typical flavour described as being similar to walnuts. The value of yoghurt in human diet is determined by the nutritive value of milk from which it is made and increased digestibility, but also on the beneficial effect of intestinal microflora, prophylactic and healing effects. Many health benefits have been attributed to yoghurt such as improved lactose tolerance, protection against gastrointestinal infection, effective treatment for specific types of diarrhea, relief of constipation improved immunity, cholesterol reduction against cancer. Summray 130 Adding nuts to dairy products (yoghurt) will be achieved two objectives, the first is making this product more tasteful and the second is boosting the dairy products effectiveness for biological activity. This study was conducted to investigate the effect of adding almond and peanut to yoghurt as dairy products to boost its effectiveness for biological activity on rats feeding with different concentrations (3%, 5% and 7%) almond to yoghurt and different concentration also (3%, 5% and 7%) of peanuts to yoghurt and there were feeding by basal diet as a –ne group and +ve group which feeding by basal diet and yoghurt without any adding(as control). Thirty-two adult male albino rats, weighting 120± 5 g were used and divided into eight groups each group there were four rats. Rats were housed in wire cages under the normal laboratory condition and were fed on basal diet for a week as an adaptation period. Rats were divided into the following groups: (4 rats pear each group) Group 1: negative control group ,in this group rats were kept on basal diet and tap water Summray 131 Group 2: positive control group In this group rats were feed on basal diet plus( 5 g from yoghurt without any adding ). Group 3: basal diet plus 5 g yoghurt with treated 3% almonds. Group 4: basal diet plus 5 g yoghurt with treatment 5% almonds. Group 5: basal diet plus 5g yoghurt with treatment 7 % almonds. Group 6: basal diet plus 5 g yoghurt with treatment 3% peanuts. Group 7: basal diet plus 5 g yoghurt with treatment 5% peanuts. Group 8: basal diet plus 5 g yoghurt with treatment 7 % peanuts. At the same time, the organs of heart, liver, kidney, lung and spleen were moved from each rat and weight,and then saved in formalin solution 10% for histopathological examination. Statistical analysis: Data were analyzed using a completely randomized design (SAS, 1985) when a significant main effect was detected, the means were separated with the student-Newman-Keuls Test. Differences between treatments of (P≤0.05) were considered significant The obtain result can be summarize as following : The chemical analysis results. It could be observe that the tested fruits (almondsand peanuts) in all have a modest contents of protein and ash , higher contents of fats and a markedly contents of carbohydrates and fibers. Almond: Summray 132 (Moisture 5.39 g%, Protein 18g% , Fat 53.4 g% , Ash 8.9 g%, Carbohydrates11.3 g% , Fiber 2.9 g%, Calories 591 g%).

No histopathological changes were noticed in lung of rat from Summray 142 group 1. However, lung of rats from group 2 & 3 should focal interstitial pneumonia and thickening of interstitial tissue. Mean while, lung of rat from group 4 revealed no histopathological changes. Examined sections from group 5 revealed focal emphysema and from focal to diffuse interstitial pneumonia . No histopathological changes were noticed in lung of rat from group 6. Spleen : Microscopically, Spleen of control – ve rat revealed the normal lymphoid follicles. However, spleen of control + ve rat showed slight lymphocytic necrosis and depletion .Meanwhile, spleen of rats from groups 1 , 2 , 3 , 4 , 5 & 6 revealed no histopathological changes . The important recommendation of this study was using nuts as a function food which plays a vital role in biological activity for human not only for fun and it has a lot of benefit. Also, nuts can make the yoghurt tasteful as more. |
