“…The average chemical composition of tiger nut tubers are as the fellows: 34% starch, 25% oil, 8% protein, 16% sucrose, 10% fiber and 7% others. The tubers were found to contain 12.4 and 8.5 µg/g of the isoflavons daidzein and genistein, respectively and about 18.6 mg of vitamin E /100 g oil (Zommara & Imaizumi, 2017). Accordingly, tiger nut-diet was adjusted for its content of oil, protein, corn starch and sucrose.…”

“…The hypolipidemic effect of tiger nut may be explained by its content of, polyunsaturated fatty acids (~ 9.9% of total fatty acids), isoflavones (daidzein and genistein (12.4 and 8.5 μg/g, respectively) (Zommara & Imaizumi, 2017) and phytosterols (168 mg/100 oil). Diets enriched with polyunsaturated fatty acids (PUFA) have been recommended for several medical and nutritional aims because of the lipid lowering effects of PUFA in the serum Schmid &Woollett, 2003).…”

“…Tiger nut oil has a high oleic acid content (~ 70%) and low content of polyunsaturated fatty acid (linoleic acid and linolenic acid) (~ 9.9%) (Zommara & Imaizumi, 2017). Belewu & Abodunrin, (2006) demonstrated that tiger nut oil reduces blood low density lipoproteincholesterol (LDL-C) and increases high density lipoprotein-cholesterol (HDL-C), reduces blood triglycerides level and the risk of forming bloody clots, thereby preventing arteriosclerosis.…”

“…It also contains several micronutrients such as vitamin E, phytosterols, isoflavones, etc. The chemical composition and nutritional value of tiger nut tubers is presented elsewhere (Mokady & Dolev, 1970, Oladele & Aina, 2007, Shaker et al, 2009, S´anchez-Zapata et al, 2012and Zommara & Imaizumi, 2017. Tiger nut has been found to be good for preventing arteriosclerosis, since its consumption can help prevent heart problems and thrombosis and activate blood circulation (Chukwuma et al, 2010), mainly because its unsaturated fatty acid content is similar to that of olive oil (Linssen et al, 1988) and its arginine is a precursor of nitric oxide which helps the veins to expand (Mart´ınez-Valls, 2003).…”

“…In our previous studies, Tiger nut (chufa) oil and its water and methanol fractions exhibited in vitro anti-lipoperoxidation effect against peroxidation stress initiated by ferrous ions dependent peroxidation stress and in free radical mediated peroxidation by the water soluble initiator 2,2'-azobis (2-aminopropane) dihydrochloride (AAPH) and the lipid soluble free radicals initiator 2,2'-azobis (2,4-dimethylvaleronitrile) (AMVN) in phosphatidylcholine liposomes El-Shaer, 2001 andImaizumi, 2017). The aim of this study was therefore to investigate the influence of supplementing a diet with whole powder of tiger nut tubers on serum lipids and atherosclerosis parameters in apoE -/mice.…”

Bu çalışmada, farklı yer bademi çeşitlerinin (Sarı şeker, İntrodüksiyon 1, Bal yumru) besin madde değerlerinin ve koçlarda sindirilebilirliklerinin belirlenmesi amaçlanmıştır. Farklı yer bademi çeşitlerinin ortalama gaz üretimi, 96 saatlik inkübasyondan sonra in vitro gaz üretim kinetiği ve in vitro inkübasyon süreleri belirlenmiştir. Yetiştirilen farklı yer bademi çeşitlerinin in vitro gaz üretim tekniği kullanılarak a, b, c, a + b'nin pearson korelasyon katsayıları ve pearson korelasyon katsayıları bulunmuştur. Çalışmada farklı yer bademi çeşitlerinin değişik zamanlardaki ortalama gaz üretimleri sadece 3. saatte önemli bulunmuş; 96 saatlik inkübasyondan sonraki in vitro gaz üretim kinetikleri, çeşitler arasında farklılık yaratmamış; in vitro inkübasyon zamanları ile pearson korelasyon katsayıları arasındaki ilişki önemli tespit edilmiştir. Yer bademi çeşitlerinin ortalama ham proteini (HP) %4.39; kuru maddesi (KM) %94.08; ham yağı (HY) %24.85; ham külü (HK) %2.53; asit deterjanda çözünmeyen lif (ADF) %15.04, nötr deterjanda çözünmeyen lif (NDF) %24.03; lif olmayan karbonhidrat (LOK) %44.20 olarak bulunmuştur. Yer bademi çeşitlerinin ortalama toplam sindirilebilir besin maddesi %72.78; metabolik enerjisi 2.63 Mcal/kg KM, sindirilebilir enerjisi 3.21 Mcal/kg KM ve de net enerji laktasyon değeri 1.66 Mcal/kg KM olarak tespit edilmiştir.

Dietary lipids play a major role in many diseases, particularly cardiovascular diseases. Recently, the health value of plant oils, particularly heart health, has been recognized. Despite these facts, limited information is available on the potential nutritional and anti-arteriolosclerosis effects of chufa oil, olive oil, and anhydrous milk fat in C57BL/6N mice. In the present study, the effects of olive oil (OO), chufa oil (CO), and anhydrous milk fat (AMF) on 4-week-old C57BL/6N male mice, a model for studies of diet-induced atherosclerosis, were investigated. The AIN-93G-based diet was supplemented with 15% of either OO, CO, or AMF. The final mixture of the diets contained 15% fat, approximately 1.25% cholesterol, and 0.5% sodium cholate. The data obtained showed that most mice had gallstone disease. The highest percentage of the gallstones formed were found in AMF groups (approximately 85.7% of the mice). However, the lowest one was found in the chufa oil group (42.9%), followed by the olive oil group (57.1%). Although the mice’s food intake significantly differed, their body weights did not change during the feeding period. The diet supplemented with CO resulted in a significant reduction in serum cholesterol compared with the other groups. Livers from the CO-fed group showed higher triglyceride levels than those from the AMF group. No significant differences were found in atherosclerotic lesions in the aortic valve between the groups. Collectively, our results show no deleterious nutritional effects of the fats used on C57BL/6N mice fed cholesterol-rich diets. Chufa oil improved cholesterol metabolism and atherogenic index in mice. However, the major issue is the formation of gallstones in all mice, which is most prominent in AMF, followed by olive oil and chufa oil diets.
