The review covers mainly the nutritional bar and health effect of athletes, but almost half third of the article is on date palm and its effect on human health, which is broadly describes in the previous articles. Some of these article as recently published in 2019 and 2020, such as:

If you want to publish this review then you should only focus on the effect of date palm to make nutrition bar for athletes. Also focus on the sport industry and add some latest studies in the review.

Therefore, I recommend that the manuscript should not be considered for publication in this journal.
