Polyphenols are dietary constituents of plants associated with health-promoting effects. In the human diet, polyphenols are generally consumed in foods along with macronutrients. Because the health benefits of polyphenols are critically determined by their bioavailability, the effect of interactions between plant phenols and food macronutrients is a very important topic. In the present review, we summarise current knowledge, with a special focus on the in vitro and in vivo effects of food macronutrients on the bioavailability and bioactivity of polyphenols. The mechanisms of interactions between polyphenols and food macronutrients are also discussed. The evidence collected in the present review suggests that when plant phenols are consumed along with food macronutrients, the bioavailability and bioactivity of polyphenols can be significantly affected. The protein–polyphenol complexes can significantly change the plasma kinetics profile but do not affect the absorption of polyphenols. Carbohydrates can enhance the absorption and extend the time needed to reach a maximal plasma concentration of polyphenols, and fats can enhance the absorption and change the absorption kinetics of polyphenols. Moreover, as highlighted in the present review, not only a nutrient alone but also certain synergisms between food macronutrients have a significant effect on the bioavailability and biological activity of polyphenols. The review emphasises the need for formulations that optimise the bioavailability and in vivo activities of polyphenols.

Underutilised fruits are not only important sources of food and nutrition, but also secure household income especially for rural and farm communities. However, some of the underutilised fruits have not received much attention as compared to commercial fruits. This could be due to their lack of knowledge of their potential values. Hence, information about their health promoting properties is critical to increase the value of underutilised fruit species to enhance their preservation and sustainable use in strengthening food, nutrition, health and livelihood security. This article aims to provide a comprehensive review on the phytochemical properties and biological activities of underutilised fruit species grown in Malaysia focussing on health promoting aspects. With regard to phytochemistry, only 21 species of underutilised fruits have been identified and quantified. Phytochemical investigations of various parts of the fruits have revealed the presence of over 100 phytochemicals which are phenolics, terpenoids, carotenoids and other miscellaneous compounds. About 51 underutilised fruit species have been explored for interesting biological activities (antioxidant, antimicrobial, anticholinesterase, cytotoxicity, antiatherosclerotic, antihyperlipidemia, antidiabetic, cytoprotective, cardioprotective and antiplatelet activities) supporting their diverse traditional uses. Different parts of the fruits have been analysed mainly in vitro and barely in vivo, with pulp being the most dominant. Of all the underutilised fruits studied, Mangifera species and Canarium odontophyllum have been the major focus for researchers. The gaps obtained from this review create further research opportunities to add to the current knowledge of health promoting properties of underutilised fruits in Malaysia. More studies are needed to confirm the health significance and explain their mechanisms of action in order to fully understand the real potential of this underutilised fruit species.

Many mushroom species are consumed as food, while significant numbers are also utilised medicinally. Mushrooms are rich in nutrients and bioactive compounds. A growing body of in vitro, in vivo, and human research has revealed their therapeutic potentials. Some of the most notable benefits include such properties as anti-pathogenic, antioxidant, anti-inflammatory, immunomodulatory, gut microbiota enhancement, and angiotensin-converting enzyme 2 specificity. The use of medicinal mushrooms (MMs) as extracts in nutraceuticals and other health products are burgeoning. COVID-19 presents an opportunity to consider how, and if, specific MM compounds might be utilised therapeutically to mitigate associated risk factors, reduce disease severity, and support recovery. As vaccines become a mainstay, MMs may have the potential as an adjunct therapy to enhance immunity. In the context of COVID-19, this review explores current research about MMs to identify the key properties claimed to confer health benefits. Considered also are barriers or limitations that may impact general recommendations on MMs as therapy. It is contended that the extraction method used to isolate bioactive compounds must be a primary consideration for efficacious targeting of physiological endpoints. Mushrooms commonly available for culinary use and obtainable as a dietary supplement for medicinal purposes are included in this review. Specific properties related to these mushrooms have been considered due to their potential mediating effects on human exposure to the SARS CoV-2 virus and the ensuing COVID-19 disease processes.

<p class="abstrak2">Sweet potato plant is produced in Indonesia in large quantities. Sweet potato leaves and stems can be used as a source of protein and the tuber can be used as an energy source. This study was aimed to analyze the effect of feeding of sweet potato biomass on the rumen fermentation characteristics, digestibility of dry matter and organic matter as well as rumen microbial population of thin tail sheep. This study used a randomized block design by applying four feed treatments, i.e., T0 (100% Napier grass), T1 (70% of Napier grass + 30% concentrate), T2 (50% of Napier grass + 50% sweet potato leaves), and T3 (70% sweet potato leaves + 30% sweet potato tuber) with three replicates. Rumen fluid samples were taken with stomach tube method using a vacuum pump.  Results showed that the T3 diet has higher (P&lt;0.05) digestibility of dry matter and organic matter, concentration of NH<sub>3</sub> and VFA, and rumen bacterial population than those of T0 and T1diets but similar to that of T2 diet. Rumen pH and protozoa population was not different among the treatments. It can be concluded that the use of sweet potato biomass can improve the quality of rumen fermentation of sheep.</p>
