Abstract

The rise in consumption of energy-dense foods has resulted in the displacement of several essential dietary gaps, causing numerous long-lasting diseases, including obesity, stroke, hypertension, and several forms of cancer. Epidemiological studies encourage more fruit consumption to prevent these diseases. The defensive mechanisms provided by these fruits against illness are due to the existence of several antioxidants. Recent studies proved that (poly) phenolic compounds are ideally the core phytochemicals with both functional and health-promoting properties found in the plant's kingdom, and low intake could result in the risk of certain diseases. Phytonutrients are powerful antioxidants that can modify metabolic activation and detoxification of carcinogens. The ideal motive of this review is to provide an overview as well as illuminate the polyphenolic merits of fruits in general. Fruits have several merits, including weight maintenance, proper health development, and satiety. There are many analytical methods for determining and measuring the phenolic content of different products. Phenolic compounds are of nutritional interest since they aid in the retardation and inhibition of lipids by acting as scavengers that prevent and protect the proliferation of oxidative chains. Future studies are required to help identify the physiological metabolic activities as well as to improve human health.

Highlights

  • The growth, urbanization, and economic development of Africa and the world at large have resulted in a dietary transition and evolution from a traditional to a modernized diet, where the quality of food has been affected

  • Since oxidizing species and other radicals are accountable for oxidative stress resulting in several long-lasting diseases, such as cardiovascular disease, cancer, and diabetes, antioxidant capacity of phytochemicals is the primary mechanism in the prevention of such diseases and promotion of human health [68, 69]

  • The consumption of this substance or compound is good for human health since it aids in the retardation and inhibition of lipids by acting as scavengers that prevent and protect the proliferation of oxidative chains

Summary

Introduction

The growth, urbanization, and economic development of Africa and the world at large have resulted in a dietary transition and evolution from a traditional to a modernized diet, where the quality of food has been affected. The consumption rate of fruits has attracted attention since many biochemical and epidemiological studies have focused on the merits associated with the regular intake of these natural diets and the reduction rate of several ailments such as cancer and chronic and heartrelated diseases. Phenols have double or more hydroxyl groups, which are the biologically active substance that occurs in food plants mostly consumed by a considerable number of people. It is represented chemically as C6H5OH, with a structure of hydroxyl group (-OH) fused to a phenyl ring.
