1. Introduction
Food security is and has been one of the strategic imperatives for the South African government and policy makers. This is expressed in many governments’ policy documents, including the constitution and the national development plan. The right to have access to sufficient food for all citizens is enshrined in the constitution of the country. While South Africa is nationally food secure, several households face food security challenges [
1,
2]. The state of food and nutrition vulnerability in South Africa has been exacerbated by economic hardship due to high rates of unemployment and the outbreak of COVID-19, with associated control measures implemented by the government to contain its spread. GHS 2020 revealed that between 2019 and 2020, the proportion of households and individuals that were vulnerable to hunger increased from 10.3% to 10.8% and 11.1% to 11.6%, respectively [
3]. In the same period, the number of households and individuals who experienced difficulties with food access also increased by 2.8% and 2.5%, respectively.
Agriculture plays an important role in the process of economic development and can significantly contribute to household food security. Although several policy decisions and programs have been implemented to address food and nutrition insecurity over time, programs promoting the production and consumption of fruits and vegetables still need special attention, as the literature has shown that many South African do not produce and consume vegetables [
1,
4]. In 2020, only 17.5% of South African households were reportedly involved in agriculture. Of the nine provinces of South Africa, Limpopo had the highest proportion of households engaged in agriculture, with 37.5% of the households involved in agriculture [
3]. Generally, fruits and vegetables are not produced by higher numbers of households, let alone consumed by them. However, agriculture, including fruits and vegetables, may contribute positively and directly to improving the food security status [
5,
6].
Nutrition-sensitive agriculture or the production of foods with high nutrient densities (such as dairy, fish, fruit, meat, and vegetables), is recognized as a pathway to improve food and nutrition security [
6]. As noted by Vinceti et al. [
7], fruits and vegetables could address the need for nutritious and adequate food in the context of many challenges facing South Africa and Africa in general, including reducing poverty and hunger, improving environmental health, enhancing human well-being and health, and strengthening local food networks, sustainable livelihoods, and cultural heritage.
Fruit and vegetable production contributes to household food security by providing direct access to food that can be harvested, cooked, and served to family members, usually daily [
8]. Even the poorest, most landless, or near-landed people are accustomed to farming in small plots of land, uninhabited areas, sidewalks or the edges of fields, or in containers. Farming can be accomplished without economic resources, using locally available planting materials, green manure, “living” fences, and traditional pest control methods. Farming provides a variety of new foods that improve the quantity and quality of the nutrients that are available to a family. Increasing fruit and vegetable production is an obvious first step [
5].
Growing population figures and rising wages, especially in urban areas, have created an increase in market demand as consumers seek to diversify their food intake. Increasing vegetable production to meet this need creates significant economic opportunities, especially for smallholder farmers. Market-focused vegetable farming not only creates income for smallholder farmers but it also helps to build their resilience to external risks. The diversity of vegetable crops, short growing cycles, and efficient use of irrigation can reduce farmers’ risk of climate change. To grow the economy, farmers can choose to incorporate vegetables into existing cropping systems or specialize in vegetable production [

4. Discussion
The study’s objective was to investigate the contribution of fruit and vegetable consumption to food security in the Limpopo province of South Africa. The study aimed to understand the relationship between the consumption of fruits and vegetables and the factors that influence the consumption of fruits and vegetables and the food security status of households. The study revealed that very few households consumed and produced fruits and vegetables; only (n = 708) consumed fruits and vegetables and (n = 485) produced fruits and vegetables. These results were significantly low and surprising, as it is known that fruits and vegetables are crucial for a diversified, balanced, and healthy diet [
23,
24,
25]. In addition, the study found that the majority of Limpopo households were food insecure (54.2%). This is due to many determinant factors that influence food access and consumption. These results align with several studies [
2,
18,
26] conducted in Limpopo regarding the food security status of households; these studies revealed that most households were food insecure. Although Limpopo is known to be a food-secure province in South Africa [
3], many rural households still suffer from food insecurity.
The findings revealed that age had a negative impact on the consumption of fruits and vegetables, yet it was not significant. However, it had a positively significant relationship with the household food insecurity status., i.e., as the age of the household head increases, the consumption of fruits and vegetables decreased and the probability of being food insecure increased. This may suggest that older individuals were not consuming a nutritionally balanced diet. Being old decreases their chances of accessing food and consuming fruits and vegetables. These affect their daily nutrition requirements, hence compromising individual health. This can be justified by other studies that revealed that as one’s age increases, most members become less active, and there is poor involvement in food production and preparation [
27,
28,
29]. Even though most older household heads are decision-makers of the household and they manage resources, Smith et al. [
28] noted that older farmers are mostly food insecure due to their increased dependence. In addition, Hall et al. [
30], Oliveira et al. [
31], and Xaba et al. [
32] found that increasing age was associated with low fruit and vegetable consumption. These studies found that adults had poor consumption of fruits and vegetables compared to younger household members. Unlike the study conducted by Awobusuyi et al. [
33] in Nigeria, the authors found contradicting results that concluded that older household heads were more food secure than younger household heads, which justified as being older as being associated with more knowledge and farming experience.
The household head’s gender showed a significant relationship between the consumption of fruits and vegetables and the food insecurity status. Gender positively impacted the consumption of fruits and vegetables, i.e., being male was associated with increased consumption of fruits and vegetables compared to females. This may be due to the reports that females in rural households generally have more responsibilities, which include taking care of the family, household chores, meal preparations, and food distribution. They have less time to take care of themselves and eat healthy foods. Males are more prioritized as heads of the family; as a result, females have less access to food as they first distribute to the family [
30,
34]. These results are in contrast with studies conducted by Xaba et al. [
32], Dehghan et al. [
34], Simunaniemi et al. [
35], and Tamers et al. [
36], who found that female-headed households had better fruit and vegetable consumption than male-headed households. Moreover, in this study, gender negatively impacted household food insecurity, implying that female-headed households were less food insecure. This is because women are regarded as pillars of the household; they are involved in agricultural production, care, and preparing and planning meals for their families [
29,
37,
38]. These findings contradict the findings obtained in the study conducted in Niger, Brazil, which showed that male-headed households were more food secure than female-headed households [
39,
40]
The household size (household members) influences the household structure, function, food demand, availability, and consumption. This study revealed that the household size positively influenced the consumption of fruits and vegetables but was insignificant. Nevertheless, household size had a positive significant impact on the household food insecurity status., i.e., as the members of a household increases, the risk of being food insecure increases, hence the decreasing consumption of fruits and vegetables. To feed a household with a large number of family members, more resources and money are needed to buy healthy foods [
38,
41]. These findings align with the study findings by Rubhara [
42], who found a positive relationship between the household size and household food insecurity. The study concluded that an increase in household members is directly related to an increase in demand and supply, respectively; hence, the bigger the household, the more food insecure they are, and the fewer household members, the less food demand, and vice versa. On the contrary, the study conducted by Zondi et al. [
29] found that bigger household size increased food security status. Families with many household members can divide duties among each other in production or agricultural activities. In return, they can increase the food produced for consumption and surplus, which can generate income; hence, households consume a more diversified diet and increase their food availability [
43].
The results of this study also revealed that receiving grants had a negatively significant relationship with the consumption of fruits and vegetables, but it was not significant for the household food insecurity status. Additionally, receiving a social relief grant for disability had a positively significant relationship with the household food insecurity status, i.e., receiving grant decreased the level of consumption of fruits and vegetables while receiving social relief for disability increased the likelihood of being food insecure. Initially, the purpose of giving grants in SA was to ease household financial constraints and access basic needs to better their livelihood and living standards. However, due to high levels of unemployment, grants are used as the main financial support or income for households and their extended family and they cover household expenses. As food prices rise drastically, having good quality, quantity, and diversified food becomes a challenge, therefore increasing the level of food insecurity among households [
24]. These findings are in line with other studies by Okop et al. [
24], Zondi et al. [
29], Aliber [
44], and Patenaude et al. [
45], which all found that receiving the grant was associated with increased food insecurity. These studies revealed that many households in SA depend on grants or disability grants to maintain and sustain their household.
As expected, involvement in agricultural production had a positively significant relationship with the household consumption of fruits and vegetables., i.e., involvement in agricultural production increased the household consumption of fruits and vegetables. Involvement in agricultural production (includes the production of fruits and vegetables) increases food availability, improves dietary diversity, and increases income opportunities. This is consistent with findings from previous studies that have reported a good correlation between involvement in agricultural production and diet quality [

5. Conclusions and Recommendations
The role of fruits and vegetables in improving livelihoods and food security is underrated, although food insecurity continues to be a cause for concern for the government and policy makers in South Africa. Increasing the focus and promotion of the production and consumption of fruits and vegetables is a possible pathway for reducing the country’s high food insecurity levels. Therefore, this paper studied the contribution of fruit and vegetable consumption and the food security status of Limpopo province households. While households consumed and produced fruits and vegetables, more households were involved in the consumption of fruits and vegetables than production.
The consumption of fruits and vegetables considerably influenced the food security status of the household. Additionally, age, household size, and receiving social relief for disability grants had a positively significant impact on determining the household food insecurity status; however, gender had a negatively significant relationship. Numerous factors such as age, gender, household size, social grants, and involvement in agricultural production affected the consumption of fruits and vegetables. Gender and involvement in agricultural production had a positively significant relationship with the consumption of fruits and vegetables, but being a recipient of a grant had a negative impact. There is a need for government officials and local leaders to provide food security interventions that prioritize women and elders. These may include promoting household production and consumption of diversified fruits and vegetables.
Study Limitations
This paper focuses on the overall provincial food security situation. Further studies could be conducted to show the disaggregated district and municipal results. This will enable policy makers to enact district- and municipality-level-specific interventions.
