“…An HC diet, low in protein, has been shown in animal models to elevate brain Trp concentrations relative to higher-protein diets (33). When the concentration of Trp is higher than that of LCNAAs, its entry into the brain is favored and serotonin production is upregulated (34,35), which would promote sleep (24). Because the Trp-to-LCNAA ratio is affected by dietary carbohydrate intake (33,36), it is possible that changes in sleep architecture as a result of carbohydrate manipulation are mediated by the Trp-to-LCNAA ratio.…”

“…Because the Trp-to-LCNAA ratio is affected by dietary carbohydrate intake (33,36), it is possible that changes in sleep architecture as a result of carbohydrate manipulation are mediated by the Trp-to-LCNAA ratio. An HC diet or meal would increase the Trp-to-LCNAA ratio and promote sleep through increased serotonin production (33,34). Conversely, an LC diet would result in a low ratio of Trp to LCNAA, thus limiting serotonin production and prolonging SOL (25).…”

There is much emerging information surrounding the impact of sleep duration and quality on food choice and consumption in both children and adults. However, less attention has been paid to the effects of dietary patterns and specific foods on nighttime sleep. Early studies have shown that certain dietary patterns may affect not only daytime alertness but also nighttime sleep. In this review, we surveyed the literature to describe the role of food consumption on sleep. Research has focused on the effects of mixed meal patterns, such as high-carbohydrate plus lowfat or low-carbohydrate diets, over the short term on sleep. Such studies highlight a potential effect of macronutrient intakes on sleep variables, particularly alterations in slow wave sleep and rapid eye movement sleep with changes in carbohydrate and fat intakes. Other studies instead examined the intake of specific foods, consumed at a fixed time relative to sleep, on sleep architecture and quality. Those foods, specifically milk, fatty fish, tart cherry juice, and kiwifruit, are reviewed here. Studies provide some evidence for a role of certain dietary patterns and foods in the promotion of high-quality sleep, but more studies are necessary to confirm those preliminary findings.

“…Konsumsi triptofan dalam pisang mempunyai keuntungan karena kandungannya bersama karbohidrat akan mempermudah triptofan dapat melewati sawar darah otak dan dapat digunakan sebagai bahan dasar pembentukan serotonin. (Wurtman et al, 2003). Selain itu, pisang kepok merupakan sumber komponen bioaktif pembentuk serotonin, antara lain adanya kandungan Vitamin B6, B12, dan magnesium, yang berperan dalam sintesis serotonin (Emaga et al, 2007).…”

A B S T R A C TA positive energy imbalance results in overweight and obesity. Overweight and obesity are the major risk factors for many diseases, including diabetes, cardiovascular diseases, and mental health. Animal studies suggested that serotonin involves in food intake control. The Banana peel is a potential natural source of serotonin precursor; furthermore, it may influence food intake. This study aimed to determine the effect of banana peel extract on food intake and body weight gain in male Wistar rats. Twenty-four male Wistar rats (8-10 weeks old), were divided into four groups for feeding treatment. All four group were; the control group (C), the banana peel extract dosage of 4 g/kg BW group (T1), the banana peel extract dosage of 8 g/kg BW (T2), and the banana peel extract dosage of 16 g/kg BW (T3). The food intakes were measured daily, while rats body weights were recorded at the beginning and the end of the three days experimental periods. The study found the rats in the T1 group (8.80 ± 2.63) showed no significant difference in food intake compared to C group (10.68 ± 1.89), T2 group (6.65 ± 3.12), and T3 group (5.42 ± 1.59). Rats in the T2 group (p = 0.038) and T3 group (p = 0.005) showed lower food intake significantly compared to control group. After three days of treatment, the T3 group showed a significant decrease in body weight compared to control group (p = 0.008). This study concluded, the administration of banana peel extract dosage of 8 g/kg BW and 16 g/kg BW suppressed food intake, while the dosage of 16 g/kg BW reduced the body weight in male Wistar rats.KEY WORDS: food intake, banana peel, Wistar rat Penulis korespondensi: WIWIEK FATCHUROHMAH |

“…Carbohydrates are suggested to increase DA production in the brain by allowing easier passage of the DA precursor, tyrosine, through the blood-brain barrier into cerebrospinal fluid [61]. Interestingly, CH with high glycemic index is shown to decrease the risk of PD by an insulin-induced increase in brain DA [62].…”

Various nutritional components belonging to different classes of natural dietary origin display modulatory (protective) properties against age-related neurodegenerative disorders (NDD) such as Parkinson's disease (PD) and Alzheimer's disease. These compounds termed as nutraceuticals which have been shown to act at various biochemical and metabolic levels and exhibit different degree of neuroprotective properties. Present review aims to summarize the current status on the modulatory impact of some of the major nutritional compounds on the pathophysiology of PD, the second most common NDD in humans. Primarily, we have examined the data demonstrated in animal models and postulated through epidemiological studies on the compounds/molecules/life style factors which reduce the risk associated with PD and probable mechanism/s through which they elicit neuroprotection. Further we also included some of the conflicting information about the compounds which may enhance the risk associated with PD. Additionally, emphasis is also given about the new approaches to understand the impact of nutrition on the epigenome in relation to the development of NDD with a short note on emerging ideas relating to nutritional genomics.
