Products for Sportspeople Containing Constituents Derived from the Common Bean Phaseolus vulgaris L. (Fabaceae)—A Narrative Literature Review

The third-largest land plant family, Fabaceae (Papilionaceae), includes trees, shrubs, and perennial or annual herbaceous plants containing both numerous beneficial constituents (e.g., proteins, carbohydrates, dietary fibre) and antinutrients (e.g., saponins, tannins, phytic acid, gossypol, lectins). The consumption of leguminous plants allows sports people to complete their requirements for nourishment but, on the other hand, it contributes to digestive system ailments. Therefore, the aim of the presented study was to review the experimental articles and patents referring to the application of common (kidney) bean (Phaseolus vulgaris L.)-based nutritional products for athletes. The survey of the literature was carried out according to PRISMA statements by browsing Scopus, PubMed and ISI Web of Science databases, as well as Google Scholar, Google Patents and Espacenet Patent Search engines using factorial combinations of the following keywords: (‘common bean’ or ‘kidney bean’ or ‘Phaseolus vulgaris’) and (‘athlete’ or ‘sport’) and (‘food’ or ‘nutrition’ or ‘diet’). Altogether, 84 patents issued in the years 1995–2023 were noted. The majority of patents were developed by research teams consisting of at least four authors representing scientists affiliated in the United States of America and China. The patents refer to the production of food ingredients, nutritional products, and compositions: (i) for relieving fatigue, enhancing endurance, and increasing muscle mass and strength, (ii) for maintaining physical and mental health, and (iii) for controlling body weight. Moreover, the analysis of 19 original articles indicated the substantial acceptability of meals containing the common bean. To summarize, the performed investigations demonstrate the considerable use of Phaseolus vulgaris in sport nutrition and the growing acceptance of this trend.


Introduction
The botanical family of dicotyledonous plants, Fabaceae (Papilionaceae), includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognised by their papilionaceous flowers, fruits, and compound, stipulate leaves.The family is the third-largest land plant family in terms of number of species, behind only the Orchidaceae and Asteraceae, with more than 720 genera and nearly 20,000 known species [1].The leguminous plants develop a symbiotic relationship with nitrogen-fixing bacteria which invade the root hairs of host plants, multiply, and stimulate the formation of root nodules.Within the nodules, microorganisms convert free nitrogen to ammonia, which the host plant utilises for its development.The nitrogen fixation is possible thanks to sugars created in photosynthesis and provided by the plant.Nodulated legumes are found in all environments except open seas and are arguably more significant at high than low latitudes [2].A detailed biogeography of nodulated legumes and their nitrogen-fixing symbionts is presented by Sprent et al. [3].
Due to the additional nitrogen that legumes receive through the process of atmospheric nitrogen fixation, they have a comparatively higher amino acid content than other species [4].Moreover, they contain carbohydrates, dietary fibre, fat, and minerals, such as calcium, copper, iron, magnesium, phosphorus, potassium, and zinc [5][6][7].They provide tremendous opportunities and challenges for use in processed foods such as bakery products, bread, pasta, soaked and dried foods, snack foods, soups, cereal bar filings, tortillas, meat, etc. [8].According to numerous authors, the consumption of legumes is suitable for sportspeople who follow different diets and present diverse eating habits, allowing them to complete their requirements for nourishment [9][10][11][12][13].Tukhtarov [9] stated that the consumption of legumes enhances the total biological value of the average daily diets of professional athletes in Uzbekistan.Rogerson [10] argued that beans are a rich source of proteins, carbohydrates, and iron, which are very important for sportspeople who follow a vegan diet.D'Angelo and Cusano [11] highlighted the value of legume consumption by sportspeople following the Mediterranean diet.Additionally, Terenzio et al. [12] pointed out that the consumption of legumes improves the sport performance of Italian athletes.Shevkani et al. [13] documented the beneficial role of proteins from leguminous plants in the qualitative improvement of gluten-free foods suitable for sportspeople with gluten-related disorders.On the other hand, despite their benefits, legumes contain antinutrients such as saponins, tannins, phytic acid, gossypol, lectins, protease inhibitors, amylase inhibitors, and goitrogens.Anti-nutritional factors combine with nutrients and are a major concern because of the resulting reduced nutrient bioavailability [14].Moreover, the substantial consumption of legume plants may contribute to digestive system ailments such as the feeling of fullness, discomfort in the stomach, bloating, and diarrhoea.The avoidance of legume consumption by athletes with gastrointestinal disorders has been advised [15] and confirmed [16] in studies.
Considering the aforementioned discrepancy, it would seem to be very interesting to conduct a review of the use of particular species representing the Fabaceae family in the nourishment of sportspeople.So far, such investigations have been conducted in the case of the soybean, Glycine max (L.) Merr.[17].
Phaseolus vulgaris is another species representing the Fabaceae family characterized by the presence of both beneficial substances, as well as the antinutrients and allergens.The beneficial substances contribute to numerous health benefits, e.g., diminished heart and renal disease risks, increased satiation, and cancer prevention.Moreover, the intake of meals comprising seeds of Phaseolus vulgaris by sportspeople contributes to meeting energy needs and to rapid recovery after injury.On the other hand, undesirable components such as antinutrients may diminish the bioavailability of trace elements, as well as limit protein and carbohydrate utilization.In light of this dichotomy, a review of the literature regarding the use of alimentary products containing Phaseolus vulgaris by sportspeople is strongly desirable.At the same time, it should be added that a review of patents for beverages enriched with plant proteins derived among others from Phaseolus vulgaris and intended for use by athletes was presented by Arbach et al. [18].Nevertheless, the current state of knowledge on the use of the common bean in sport nourishment is insufficient; therefore, the present investigations were undertaken.The main objectives were to learn: (i) Which constituents of Phaseolus vulgaris are used in food products dedicated to sportspeople?(ii) What are the effects of the activity of Phaseolus vulgaris constituents in food products?(iii) What is the frequency and time of intake of food products by sportspeople?

Study Species
The common bean Phaseolus vulgaris L. [19] can grow as an annual in temperate climates and as an annual or short-lived perennial in tropical climates.The species is highly variable, from erect bushes measuring 20-60 cm in height to running vines reaching 2-3 m in length.All varieties bear alternate green or purple leaves, which are divided into three oval, smooth-edged leaflets, each 6-15 cm long and 3-11 cm wide.The white, pink, or purple flowers are about 1 cm long, and they give way to pods 8-20 cm long and 1-1.5 cm wide.These may be green, yellow, black, or purple, each containing 4-6 oblong-ellipsoid beans.The beans are smooth, plump, kidney-shaped, up to 1.5 cm long, ranging widely in colour and are often mottled in two or more colours.
The domestication of Phaseolus vulgaris occurred independently in the Mesoamerican and Andean areas, which gave rise to two highly differentiated gene pools.The Mesoamerican common bean probably arrived in Europe through Spain and Portugal in 1506, and the Andean in the same way in 1528, after the exploration of Peru by Pizarro.The genetic structure of European populations is presented by Angioi et al. [20].Due to extensive plant-breeding efforts, Phaseolus vulgaris L. comprises numerous cultivars (e.g., navy bean, pinto bean, red kidney bean, black kidney bean, white kidney bean) with a wide range of morphological and agronomic characteristics, including differences in seed size and colour as well as growth habit [21].

Literature Search
The author searched for peer-reviewed original full-text articles and patents regarding the application of a kidney bean diet for sportspeople using Scopus, PubMed, and ISI Web of Science-indexed publications.These search engines were selected as they provide a comprehensive all-encompassing database for various interdisciplinary domains.Moreover, publications were searched by browsing Google Scholar.Patents were searched by browsing the Google Patents and Espacenet Patent Search engines, because they gather the largest number of open access patents.The review focused on literature records published up to 2023.The author used factorial combinations of the following keywords in the searches: ('common bean' or 'kidney bean' or 'Phaseolus vulgaris') and ('athlete' or 'sport') and ('food' or 'nutrition' or 'diet').The selection terms were examined from the title, abstract, and keywords of the articles.The literature search was conducted from 1 May to 1 July 2023.The results included 87 hits from the ISI Web of Science, 97 hits from Scopus, 1042 from PubMed, 1061 from Google Scholar, 1157 from Google Patents, and 4687 from Espacenet.After the manual removal of grey literature (blog posts, letters, manuals, guides, bulletins, newsletters, editorials, commentaries, theses, dissertations, reports, conference proceedings, and meeting notes) from the lists of searches, the patents and peer-reviewed articles were selected.

Data Extraction and Synthesis
To assess the quality of the included studies, all patents and articles were subjected to critical double screening.The following data were extracted: authors, affiliation of first author, year of publication, title, and characteristic of invention (in the case of patents), as well as authors, title and year of publication, and the age, gender, and nationality of participants and study findings (in the case of articles).A final total of 84 patents and 19 original articles were selected to be reviewed.A chart detailing the search results is presented in Figure 1.Results are reported in a narrative synthesis, using a textual approach to analyse the relationships within and between studies.
The statistical significance of differences in the number of patents in the study periods 1995-2001, 2002-2008, 2009-2015 and 2016-2023 was checked using the non-parametric Kruskal-Wallis H test.

An Overview of Patents
Altogether, 84 patents issued in the years 1995-2023 were noted.The number of patents increased systematically in consecutive years up to the year 2017, when the greatest number of inventions was patented.During subsequent years, a slight decrease in the number of patents was observed (Figure 2).Regarding the number of patents issued in consecutive periods, it can be stated that significant differences were noted between the period 1995-2001 (when the lowest number of patents was issued) and the period 2010-2016 (when the greatest number of patents was observed) as well as the period 2017-2023 (when a considerable number of patents was noted) (Table 1).

An Overview of Original Scientific Articles
The majority of authors focused on the investigation of the consumption frequency of meals containing kidney beans based on the diagnostic survey method with the use of a questionnaire in female and male sportspeople practicing varied sport disciplines (Table 7).The substantial consumption of meals comprising kidney beans was reported by sportspeople from Brazil [122][123][124]; however, their acceptance by para-athletes was rather low [125].The substantial consumption of kidney beans was recorded in sportspeople from Ireland [126], as well as Kenya [127][128][129] and the Republic of Congo [130].Additionally, in India [131] and Iran [132] the intake of products based on kidney beans is considerable.In turn, the use of kidney beans by vegan runners from Germany, Austria, Switzerland is substantial [133], wherein female athletes exhibit a greater intake of beans than male athletes [134].According to Vinci [135], the incorporation of beans into the diet of athletes leads to an increase in protein intake.On the other hand, investigations by several authors [136][137][138][139] showed low consumption of kidney bean by sportspeople from Australia and the UK.Table 7.A review of original articles devoted to the frequency and time of eating of Phaseolus vulgaris L. by sportspeople in alphabetical order.Abbreviations: Gender: F-female, M-male, Country: Australia (AU), Austria (AT), Brazil (BR), The Republic of the Congo (CG), Germany (DE), India (IN), Iran (IR), Ireland (IE), Kenya (KE), Switzerland (CH), United Kingdom (UK), United States of America (US).Moreover, the effects of the intake of products containing kidney bean constituents were investigated by Wei [140], who showed that consumption of high-protein, low-calorie food does not influence the body height and weight of teenage male and female gymnasts.

Discussion
The increase in the number of patents in consecutive years up to year 2017 noticed in the presented study followed by an insignificant decrease in subsequent years corresponds to other findings.A similar tendency was observed previously in the case of patents containing constituents from the soybean Glycine max (L.) Merr.[17] and maize Zea mays L. [141].Such a phenomenon may be linked to growing interest in the use of plant constituents (particularly proteins) in sport nutrition e.g., [142,143] and the literature cited here.The greatest number of patent-holders representing the United States of America and China might be linked to the considerable cultivation of Phaseolus vulgaris in the aforementioned countries, reflected in the increase of yearly yield documented in China since the 1960s [144] and in the United States between the years 1909 and 2012 [145].Moreover, an increase in production of dry beans (pinto bean, navy bean, kidney bean and others) in the United States in the years 1990-2020 was reported by Siddiq et al. [146].Such findings are consistent with studies by Uebersax et al. [147], who pointed out that, regionally, Asia leads in common bean production, followed by North, Central, and South America and Africa, while Europe and Oceania contribute only slightly to total production.The investigations conducted showed that that the majority of patents were created by research teams consisting of at least four scientists.Such a phenomenon is consistent with the worldwide tendency of the transformation of scientific research patterns in the natural sciences from individual research to teamwork [148].
The variety of patents seems to confirm the wide range of applications of common bean constituents.A substantial number of inventions concerned food ingredients.The numerous patents applying the amino acids, polypeptides and proteins derived from Phaseolus vulgaris in sport nutrition correspond with findings of many authors pointing out the substantial antioxidant activity of black bean protein hydrolysates [149,150] and their considerable use in the production of beverages such as sport drinks [18].Other patents concern the use of saccharides from kidney beans in sweeteners or the use of flavonoids (such as isoflavones and anthocyanidins) occurring inter alia in fruits and seeds.At the same time, Kan et al. [151] noticed that non-white bean seed coats which contained more anthocyanidins showed much higher antioxidant activities than white ones.Considering the widely documented toxicity of some constituents of Phaseolus vulgaris see [37], a patent obtained by Hossen et al. [63], which presents methods to reduce saponin compound content, is very valuable.Moreover, it corresponds to other investigations addressing the efficacy of various methods of processing raw materials of leguminous plants, inter alia Phaseolus vulgaris.Khrisanapant et al. [152] investigated the effects of hydrothermal processing of varying durations on the texture, starch content, and protein digestibility of pulses, inter alia Phaseolus vulgaris.Moreover, Samtiya et al. [14] and Sharma [153] reviewed several processing techniques and methods such as fermentation, germination, debranning, autoclaving, soaking etc., which might be used to reduce the antinutrient contents in pulses.At the same time, it is worth mentioning that cooked seeds of the common bean may not be completely digested and absorbed in the bowel.The fermentation caused by bacterial activity contributes to the formation of gas and flatulence responsible for the gastrointestinal symptoms frequently reported by athletes [15].
The considerable number of patents concerning sport nutrition noticed in the review conducted here seem to confirm the findings of Arbach et al. [18] showing the frequent use of Phaseolus vulgaris in nutritional products.A similar phenomenon was also observed by Kostrakiewicz-Gierałt [154], who studied plant-based patents dedicated to vegan and vegetarian sportspeople.Moreover, numerous authors have patented compositions comprising Phaseolus vulgaris constituents suitable for relieving fatigue, enhancing endurance, as well as increasing muscle mass and strength.An improvement in athletic performance and/or adaptation to training was demonstrated as a result of consumption of supplements or meals based on other leguminous plants, among others soy, e.g., [155][156][157] and pea e.g., [158].On the other hand, Mizelman et al. [159] (2020) stated that a pulse-based diet does not affect performance among soccer players.Patents containing constituents from Phaseolus vulgaris focusing on the maintenance of athletes' health and prevention of disorders correspond to findings regarding the beneficial effects of the administration of constituents derived from other leguminous species on chronic pain, discomfort due to chondral injuries and bone resorption [160,161].Moreover, patents maintaining the immune system of sportspeople and containing constituents from Phaseolus vulgaris seem to confirm the anti-inflammatory activity of legumes widely reported by Zhu et al. [162].The recipes for compositions containing Phaseolus vulgaris constituents suitable for controlling body weight correspond to the findings of other authors e.g., [163,164], who demonstrated that plant-based diets comprising, among others, beans, chickpeas and soy contribute to significant weight loss in athletes.On the other hand, the investigations of Wei [140] documented a lack of change of body weight among teenager gymnasts as an effect of the consumption of high-protein, low-calorie food containing inter alia, kidney beans.Summarizing, it should be pointed out that the present literature review showed, on the one hand, a large number of patents dedicated for sportspeople but on the other hand, an insufficient number of studies focusing on the effects of the intake of products containing the kidney bean on the mental and physical health of sportspeople.
Generally, the consumption of the common bean by athletes partly reflects the main trends of the worldwide consumption of Phaseolus vulgaris.The substantial consumption of the common bean by athletes from India may be surprising considering the fact that, although India is a leading producer of dry beans [146], the common bean does not represent the most popular legume crop in traditional cuisine [165,166].The acceptance of the common bean by athletes from the United States of America seems to correspond with the culinary traditions of ethnic groups [167] and the recommendations of the US Department of Agriculture [168] but is not consistent with low consumption by the US population [169].In turn, the low rating of the common bean by athletes from Australia seems not to support the tendency of substantial consumption of Phaseolus vulgaris by Australian people [170].Additionally, the sporadic intake of bean products declared by athletes from the UK does not correspond to overall consumption in the aforementioned country [171].On the other hand, the considerable intake by athletes from Ireland, Switzerland, Austria, and Germany (particularly those following a vegan diet) might indicate an emerging tendency of more frequent consumption of plant proteins in western European food cultures, e.g., [172,173].Moreover, the substantial consumption of beans by Brazilian athletes is consistent with the fact that Phaseolus vulgaris is considered to be a main pulse crop in Brazil, with old traditions of consumption and a variety of cultivars important in the local and international market [174].Furthermore, the considerable consumption of the common bean by athletes from Kenya and The Republic of the Congo is consistent with fact that the common bean is recognised as a crop that can ensure food security in many countries of Sub-Saharan Africa [175,176].Likewise, numerous authors have stated that the common bean is an important source of protein for both poor and wealthy households in Kenya [177] and The Republic of the Congo [178], as well as Benin [179], Burundi [180], Tanzania [181] and others.What is more, the considerable consumption of meals containing the common bean by athletes from Iran is consistent with substantial consumption of dry beans by the Iranian population, documented by Siddiq et al. [146].The present review of literature revealed that despite the growing scientific interest in the assessment of the frequency of consumption and acceptance of meals containing the common bean, a gap in knowledge still exists.Therefore, the continuation of such investigations covering in particular Central and Eastern European, as well as Asian countries seems to be strongly needed.Crosssectional studies among sportspeople of different nationalities representing diverse sport disciplines seems to be desirable.
To sum up, based on the performed investigations, it can be stated that food products containing Phaseolus vulgaris can be recommended for sportspeople and sports practitioners.The Phaseolus vulgaris constituents are effective for enhancing athletic endurance and recovery.The reduction or elimination of antinutritional constituents and improvement of protein digestibility during processing contribute to the high potential of the kidney bean to be used as a raw material for the manufacturing of food products (dedicated especially for sportspeople who do not suffer from intestinal problems).At the same time, it should be added that the future directions of research should concentrate on: (i) the effects of food products containing the common bean on the health of sportspeople, (ii) extensive research on the frequency of intake of meals containing the common bean, especially in the countries of Central and Eastern Europe and Asia and (iii) a comparison of the use of selected constituents derived from Phaseolus vulgaris and other species belonging to the Fabaceae family in the chosen kinds of food products dedicated for sportspeople, such as drinks, bars, cakes, and others.

Conclusions
The noticed increase in the number of patents up to the year 2017 related to products suitable for sportspeople containing Phaseolus vulgaris, followed by a slight decrease in subsequent years, may be linked to growing interest in the use of plant constituents in sport nutrition.The majority of patents developed in large research teams by scientists affiliated mainly with the United States of America and China correspond to the considerable cultivation of Phaseolus vulgaris in the aforementioned countries.Many patents involve the production of food ingredients and methods of processing raw leguminous materials, which is particularly important in the context of antinutrient occurrence.However, the majority of patents concern nutritional products in small forms (e.g., bars, biscuits, chips), sweet or savoury fillings, and instant powders, as well as wholesome meals.Other patents present recipes for nutritive compositions: (i) for relieving fatigue, enhancing endurance, and increasing muscle mass and strength, (ii) for maintaining physical and mental health, and (iii) for controlling body weight.The large number of patents indicates the beneficial role of constituents of the common bean in the health and recovery of sportspeople.Generally, the consumption of the common bean by athletes partly reflects the main trends of the worldwide consumption of Phaseolus vulgaris.In particular, the substantial consumption of the common bean by athletes from India and the USA and its sporadic use by sportspeople from Australia and the UK may be surprising.On the other hand, the considerable consumption of the common bean by athletes from Brazil, Iran, and African countries is consistent with long culinary traditions and food habits, while the substantial consumption of the common bean by athletes from Ireland, Switzerland, Austria, and Germany may indicate an emerging tendency towards plant protein consumption in western European food cultures.To summarize, the performed investigations demonstrate the substantial use of Phaseolus vulgaris in sport nutrition and the growing acceptance of this trend.The future directions of research should concentrate on (i) the effects of food products containing the common bean on the health of sportspeople, (ii) the frequency of intake of meals containing the common bean by sport practitioners, and (iii) a comparison of the use of selected constituents derived from Phaseolus vulgaris and other species belonging to the Fabaceae family in the chosen kinds of food products dedicated to sportspeople, such as drinks, bars, cakes, and others.
