“…Ash indicates mineral content in the samples, which refers to an inorganic foodstuff residue that remains after ignition or complete oxidation of organic matter 37 . Hence, the crude ash content represents the mineral salts present in food, 38 with the sweet potato a better source of mineral salts than cassava and taro. In the case of the crude lipid content, results showed no significant difference (p > 0.05) between sweet potato (1.36%) and cassava (1.25%), as opposed to taro with 1.85% in lipid.…”

Diabetes is the tenth most common comorbidity in coronavirus disease, hence COVID-19 patients with this disease showed higher mortality rates and worse outcomes. Therefore, Management of diabetes during the pandemic became more critical, especially in ensuring patients consume functional foods containing diets, such as sweet potato, cassava, and taro, among the top ten abundant-traditional tubers in Indonesia. These foods are rich in protein, vitamin C, thiamine, riboflavin, niacin, and dietary fibre. Carbohydrate-rich foods, which constitute around 60% of the average diet should be considered. This study evaluated the potential of the three most consumed Indonesian tubers; sweet potato, cassava, and taro, as functional foods for managing diabetes during the pandemic. These foods were selected based on their chemical composition, antioxidant activity, and in silico molecular docking against COVID-19 and diabetes-related target proteins. The target proteins are ACE2 (angiotensinconverting enzyme 2), TMPRSS-2 (transmembrane serine protease 2), DPP IV (dipeptidyl peptidase IV), and α-glucosidase. The results showed that sweet potato has the highest phenolic compounds content and antioxidant activity, valued at 7.40 ± 0.20 mg/g GAE and 9.39 ± 0.3%, respectively. Moreover, molecular docking results indicated that sweet potato phenolic compounds, namely isorhamnetin, peonidin, and catechin against DPP IV, isorhamnetin, peonidin, and quercetin against ACE2, isorhamnetin and quercetin against α-glucosidase, and epicatechin against TMPRSS2 strongly interacted with the target proteins. In conclusion, cassava, taro, and sweet potato were the most potential functional foods for diabetes management during the pandemic.

“…Several minerals essential to human health may be found in pumpkins. Phytosterols and phytonutrients are found in abundance in pumpkin pulp [ 28 , 29 ]. Carotenoids, tocopherols, and sterols found in pumpkin-derived products have a wide range of biological action, as demonstrated by in vivo studies [ 20 ].…”

Pumpkin is a well-known multifunctional ingredient in the diet, full of nutrients, and has opened new vistas for scientists during the past years. The fruit of pumpkin including the flesh, seed, and peel are a rich source of primary and secondary metabolites, including proteins, carbohydrates, monounsaturated fatty acids, polyunsaturated fatty acids, carotenoids, tocopherols, tryptophan, delta-7-sterols, and many other phytochemicals. This climber is traditionally used in many countries, such as Austria, Hungary, Mexico, Slovenia, China, Spain, and several Asian and African countries as a functional food and provides health promising properties. Other benefits of pumpkin, such as improving spermatogenesis, wound healing, antimicrobial, anti-inflammatory, antioxidative, anti-ulcerative properties, and treatment of benign prostatic hyperplasia have also been confirmed by researchers. For better drug delivery, nanoemulsions and niosomes made from pumpkin seeds have also been reported as a health promising tool, but further research is still required in this field. This review mainly focuses on compiling and summarizing the most relevant literature to highlight the nutritional value, phytochemical potential, and therapeutic benefits of pumpkin.

“…These attributes make them suitable for a wide range of applications in food and feed. In addition to their application in food and feed, pumpkin has been historically utilized in folk medicine for managing gastrointestinal diseases [12], and its seeds contain unsaturated fatty acids, phenolic compounds, tocopherols, and minerals, which enhance their potential as functional ingredients [13,14]. Together, pumpkins and their seeds offer a plethora of nutritional and medicinal benefits that can be harnessed in various applications, from functional foods to nutraceuticals.…”

Pumpkins (Cucurbita moschata), valued for their nutritional, medicinal, and economic significance, face threats from Meloidogyne incognita, a critical plant-parasitic nematode. This study extensively examines the impact of M. incognita on the growth, physiological, and biochemical responses of C. moschata. We demonstrate that M. incognita infection leads to significant growth impairment in C. moschata, evidenced by reduced plant height and biomass, along with the significant development of nematode-induced galls. Concurrently, a pronounced oxidative stress response was observed, characterized by elevated levels of hydrogen peroxide and a significant increase in antioxidant defense mechanisms, including the upregulation of key antioxidative enzymes (superoxide dismutase, glutathione reductase, catalase, and peroxidase) and the accumulation of glutathione. These responses highlight a dynamic interaction between the plant and the nematode, wherein C. moschata activates a robust antioxidant defense to mitigate the oxidative stress induced by nematode infection. Despite these defenses, the persistence of growth impairment underscores the challenge posed by M. incognita to the agricultural production of C. moschata. Our findings contribute to the understanding of plant–nematode interactions, paving the way for the development of strategies aimed at enhancing resistance in Cucurbitaceae crops against nematode pests, thus supporting sustainable agricultural practices.
