“…However, there are mixed results about the type of association between supplement use and fruit/vegetable consumption [3,5]; some studies cite complementary relationships [1–4], while others assert that supplement use is a means to compensate for an unhealthy lifestyle (i.e., a substitution; see Table 1) [5,6]. This implies two competing hypotheses: the health consciousness hypothesis and the health substitute hypothesis, which focus on complementarity and substitutions, respectively.…”

Background: The consumption of fruits, vegetables, and dietary supplements correlate. Most previous studies have aimed to identify the determinants of supplement uses or the distinct features of supplement users; this literature lacks a discussion on dietary supplement consumption as a predictor of fruit and vegetable consumption. Objective: This study examines how dietary supplement consumption correlates with fruit and vegetable consumption by combining scanner data and surveys of Korean household grocery shopping. Methods: Propensity score matching (PSM) is used to identify the relationship between dietary supplement consumption and fruit and vegetable consumption in a household. A logit regression using supplement consumption as the dependent variable is used. Then, the supplement takers (the treatment group) are matched with non-takers (the control group) based on the propensity scores estimated in the logit regression. The fruit and vegetable consumption levels of the groups are then compared. Results: We found that dietary supplement use is associated with higher fruit and vegetable consumption. This supports the health consciousness hypothesis based on attention bias, availability heuristics, the focusing effect, and the consumption episode effect. It rejects the health substitute hypothesis based on economic substitutes and mental accounting. Conclusions: Future research on the health benefits of dietary supplements should address the complementary consumption of fruits/vegetables and their health benefits to avoid misstating the health effects of supplements.

“…Much of the existing literature shows that supplement users have healthier dietary habits [1,3] or consume more fruits and vegetables than non-supplement users [2,4]. This is reportedly because ‘the health-conscious attitude predominates among dietary supplement users’ [7, p.896].…”

“…From our point of view, it is imperative to have more information on safety and efficacy based on clinical studies rather than only in vitro studies, and it is also important to reach a better understanding of the mechanism of action and bioavailability of these products. The first step in assessing the action of nutraceuticals is to distinguish them from the other food‐derived products, particularly food supplements, which are not always included in daily dietary habits in the presence of a specific need 12.…”

Currently, nutraceuticals do not have a specific definition distinct from those of other food‐derived categories, such as food supplements, herbal products, pre‐ and probiotics, functional foods, and fortified foods. Many studies have led to an understanding of the potential mechanisms of action of pharmaceutically active components contained in food that may improve health and reduce the risk of pathological conditions while enhancing overall well‐being. Nevertheless, there is a lack of clear information and, often, the claimed health benefits may not be properly substantiated by safety and efficacy information or in vitro and in vivo data, which can induce false expectations and miss the target for a product to be effective, as claimed. An officially shared and accepted definition of nutraceuticals is still missing, as nutraceuticals are mostly referred to as pharma‐foods, a powerful toolbox to be used beyond the diet but before the drugs to prevent and treat pathological conditions, such as in subjects who may not yet be eligible for conventional pharmaceutical therapy. Hence, it is of utmost importance to have a proper and unequivocal definition of nutraceuticals and shared regulations. It also seems wise to assess the safety, mechanism of action and efficacy of nutraceuticals with clinical data. A growing demand exists for nutraceuticals, which seem to reside in the grey area between pharmaceuticals and food. Nonetheless, given specific legislation from different countries, nutraceuticals are experiencing challenges with safety and health claim substantiation.

The growing use of dietary supplements, often combined with conventional drugs, creates a possibility of adverse reactions and interactions and asks for their safe application. The majority of patients do not disclose the use of dietary supplements to doctors; physicians are not always informed about the adoption of supplements and are often reluctant to initiate discussion on this topic. This lack of physician-patient comunication leads to an increased risk of the dietary supplements use. PURPOSE: То еstablish some of physician-patient communication problems on the use of dietary supplements. METHODS: This is a pilot study on the use of dietary supplements among the population of the town Stara Zagora. The pilot study was conducted by self-administrated questionnaire on people aged 19 to 59 years (n = 24). RESULTS: The opinion of 45.8% of all respondents in this pilot study is that when visiting doctors they have never been asked about the use of dietary supplements.78.8% of users of dietary supplements in the study did not tend to spontaneously share with their physicians that they accept food supplements. CONCLUSION: The low level of communication on the use of dietary supplements highlights the need for a new type of physician-patient relationships in order to reduce the risks associated with the use of dietary supplements.
