Reviewer 2 Report
Comments and Suggestions for AuthorsThank you very much for allowing me to review the manuscript entitled “nutrients-3573264_Perceptions and acceptability of a composite dish prepared from high iron, and low phytate: iron molar ratio iron biofortified common bean and white-fleshed sweet potato among pregnant women in rural western Uganda“ which has been submitted to the “Micronutrients and Human Health” of this journal.
This study evaluates the perceptions and sensory acceptability of a high-iron, low-phytate: iron molar ratio dish comprising white-fleshed sweet potato (WFSP) and iron-biofortified common bean (IBCB) (test food) compared to a low-iron, high-phytate: iron molar ratio dish, WFSP with conventional common bean (CCB) (control food), among pregnant women in rural Uganda.
Comments:
- The title is excessively long. I suggest: “Perceptions and Acceptability of an Iron-Biofortified Bean and Sweet Potato Dish Among Pregnant Women in Rural Uganda.” This revised title retains the essential information while being more concise and comprehensible. The authors may consider an alternative shorter title if deemed appropriate.
- The keywords are overly lengthy phrases. I recommend using MeSH (Medical Subject Headings) classification to facilitate better indexing of the manuscript.
- The introduction effectively outlines the issue of anaemia during pregnancy in low- to middle-income countries, detailing the needs of pregnant women and the potential benefits of the proposed intervention. The references cited are appropriate. However, the introduction should conclude with a clear statement of the study’s objective rather than discussing its potential utility. The authors may also consider explicitly stating the hypothesis before presenting the objective in a precise manner.
- The Materials and Methods section describes the study as a cross-sectional design conducted in 2016. Given that we are in 2025, this may be an error. Furthermore, the ethical approval is dated 2023, which raises concerns regarding consistency. Please clarify this discrepancy.
- Based on the stated objective in the abstract, the study compares two groups subjected to different dietary interventions, which suggests an experimental rather than a purely cross-sectional design. This aspect should be clarified.
- Was a sample size calculation performed? If so, this should be explicitly stated in the Materials and Methods
- The article by Hough et al. (2006) [Hough, G.; Wakeling, I.; Mucci, A.; Chambers IV, E.; Gallardo, I.M.; Alves, L.R. Number of Consumers Necessary for Sensory Acceptability Tests. Food Qual. Prefer. 2006, 17, 522–526, doi:10.1016/j.foodqual.2005.07.002] suggests an N value of 112 consumers for similar parameters, which should apply to each group being compared. Please clarify this issue.
- Line 126 states that participants were recruited through systematic sampling; however, the methodology is not clearly explained. Please specify the systematic sampling approach used and the source list. Additionally, the inclusion and exclusion criteria should be detailed. It is crucial to demonstrate that there are no significant differences between the two groups receiving different dietary interventions.
- How many women declined participation? What type of personnel was responsible for teaching the participants how to prepare the food?
- Does the study assess culinary preparation or sensory perception?
- Table 1 presents the two food preparation methods under comparison; however, no statistical significance tests are provided. These should be included to support the claims of nutritional or sensory benefits of the proposed dish.
- In the Results section, line 368 reports the mean age but does not provide the standard deviation. A table should be included detailing the baseline characteristics of the two groups to confirm the absence of significant differences.
- Tables 3 and 4 contain identical content. They should be merged into a single table. Furthermore, the comments presented in the results section should not be interpreted as results; their inclusion should be justified.
- The discussion describes this as an exploratory study. If this is the case, the title, study design, methodology, and results should reflect this to ensure consistent interpretation.
- The study’s limitations should be explicitly discussed.
- The conclusion should directly answer the research objective.
I appreciate the opportunity to review this manuscript and look forward to the authors’ revisions.

- The title is excessively long. I suggest: “Perceptions and Acceptability of an Iron-Biofortified Bean and Sweet Potato Dish Among Pregnant Women in Rural Uganda.” This revised title retains the essential information while being more concise and comprehensible. The authors may consider an alternative shorter title if deemed appropriate
Agreed, the previous title, “Perceptions and acceptability of a composite dish prepared from high iron, and low phytate: iron molar ratio iron biofortified common bean and white-fleshed sweet potato among pregnant women in rural western Uganda” was longer.
The title is now shortened and rewritten as “Perceptions and acceptability of a low Phytate: iron molar ratio Biofortified Bean and Sweet Potato Dish Among Pregnant Women in Rural Uganda”
- The keywords are overly lengthy phrases. I recommend using MeSH (Medical Subject Headings) classification to facilitate better indexing of the manuscript.
Agreed: The Keywords are now shortened as: “pregnancy; iron deficiency; iron-bean; acceptability; perceptions”
- The introduction effectively outlines the issue of anaemia during pregnancy in low- to middle-income countries, detailing the needs of pregnant women and the potential benefits of the proposed intervention. The references cited are appropriate. However, the introduction should conclude with a clear statement of the study’s objective rather than discussing its potential utility. The authors may also consider explicitly stating the hypothesis before presenting the objective in a precise manner.
Agreed: We now include the hypothesis as “We hypothesized that the low phytate: iron molar ratio, WFSP+IBCB, and the conventional high phytate: iron molar ratio, WFSP +CCB, are equally acceptable to the study pregnant women”. Lines 109-111
The objective is now restated in a more precise manner as “Therefore, this experimental study determined the sensory acceptability of a low phytate: iron molar ratio dish, WFSP+IBCB (test food), against a high phytate: iron molar ratio dish, WFSP+CCB (control food), among pregnant wom-en in rural Uganda. Their perceptions of consuming the test food during pregnancy were also explored. See lines 111-115.
4. The Materials and Methods section describes the study as a cross-sectional design conducted in 2016. Given that we are in 2025, this may be an error. Furthermore, the ethical approval is dated 2023, which raises concerns regarding consistency. Please clarify this discrepancy.No, our study was not a cross-sectional design. This may have been misread. In section “2.1, study setting and design”, it was stated that “This experimental cross-over sensory acceptability study was conducted in Bwera General Hospital, in Kasese district, Western Uganda.”
Furthermore, our study was not conducted in 2016. The “2016” is the year when the most recent Uganda Demographic Health Survey was conducted. This citation was used to justify that the prevalence of anemia among women of reproductive age, including pregnant women, in the study setting was unacceptably high at over 50%. So, the 2016 citation was used to justify that it was necessary to conduct this acceptability study in such a study area with a high prevalence of anemia.
Furthermore, the ethical approval is dated 2023, which raises concerns regarding consistency. Please clarify this discrepancy.
The ethical approval for the study was granted in 2023.
To clarify this discrepancy, we have revised section 2.1: study setting and design as
“This experimental cross-over sensory acceptability study was conducted in Bwera General Hospital, in Kasese district, western Uganda. It was necessary to conduct this acceptability study in Kasese district because it is located in the Tooro region, which is reported to have over 50% anemia prevalence among WRA [31]. Bwera Hospital was specifically chosen because it is the highest-volume health facility in the district, receiving over 500 pregnant women for ANC per month.”
5. Based on the stated objective in the abstract, the study compares two groups subjected to different dietary interventions, which suggests an experimental rather than a purely cross-sectional design. This aspect should be clarified.Yes, this was an experimental study and not a cross-sectional study.
In section 2.1, Study setting and design, we wrote that “This experimental cross-over sensory acceptability study was conducted in Bwera General Hospital, in Kasese district, western Uganda”. The word “cross-over” may have been misread as “cross-sectional.”
In the cross-over study, participants are exposed to both the intervention and control. In the context of our study, the pregnant women were exposed to both the test food and the control food during the sensory acceptability evaluation.
6. Was a sample size calculation performed? If so, this should be explicitly stated in the Materials and Methods
No, we did not calculate the sample size; our sample size was guided by Lawless and Heymann (2010-page 93) and Stone and Sidel (2004-page 185) who argue that a sample size of 50 or more participants is adequate for a sensory evaluation study where participants discriminate study samples.
This is now stated under section 2.2 study participants and sample size determination as
“A sample size of 50 participants or more is considered adequate for a valid cross-over sensory acceptability study” [33,34]. The study participants were pregnant women attending ANC services in August 2023 at Bwera General Hospital in rural western Uganda. A total of 104 pregnant women participated in the cross-over sensory acceptability study.”

7. The article by Hough et al. (2006) [Hough, G.; Wakeling, I.; Mucci, A.; Chambers IV, E.; Gallardo, I.M.; Alves, L.R. Number of Consumers Necessary for Sensory Acceptability Tests. Food Qual. Prefer. 2006, 17, 522–526, doi:10.1016/j.foodqual.2005.07.002] suggests an N value of 112 consumers for similar parameters, which should apply to each group being compared. Please clarify this issue.
This author was wrongly cited. We intended to cite “Lawless and Heymann (2010) and Stone and Sidel (2004)”, who argue that a sample size of 50 or more is adequate for a crossover sensory evaluation study.
To this end, the citation under section “2.2 Study participants and sample size determination” is now revised. It now reads: “A sample size of 50 participants or more is considered adequate for a valid cross-over sensory acceptability study” [33,34]. The study participants were pregnant women attending ANC services in August 2023 at Bwera General Hospital in rural western Uganda. A total of 104 pregnant women participated in the cross-over sensory acceptability study.
8.Line 126 states that participants were recruited through systematic sampling; however, the methodology is not clearly explained. Please specify the systematic sampling approach used and the source list. Additionally, the inclusion and exclusion criteria should be detailed. It is crucial to demonstrate that there are no significant differences between the two groups receiving different dietary interventions.
Agreed: The revised manuscript now states that systematic random sampling was used and that the source of the list was the ANC register. Please see section “2.3 sampling procedure”
The inclusion and exclusion criteria were explained in detail in section “2.4. Inclusion and exclusion criteria of study participants.”
It is crucial to demonstrate that there are no significant differences between the two groups receiving different dietary interventions.
Disagree: Please note that this was a crossover experimental study. It is worth noting that in a crossover study similar to the current study, the study participants are switched throughout to all the treatment groups (both test and control food) after a washout period (rinsing the palate between tasting the two foods). Therefore, it is not true that the two groups received different dietary interventions. Because the same set of participants is exposed to both the test and control foods, the advantage of cross-over studies is that participants act as their own controls.
9. How many women declined participation? What type of personnel was responsible for teaching the participants how to prepare the food?
There were no women who declined to participate. Therefore, it was not reported on.
What type of personnel was responsible for teaching the participants how to prepare the food?
Expert peer pregnant women selected from the community prepared the study foods. They were taught through the pilot study under the guidance of research assistants and village health team members.
This was stated under section 2.7. Preparation of test and control composite dishes by writing “The village health team members (community health workers) identified five expert peer pregnant women from the local community and invited them to Bwera Hospital kitchen to participate in the preparation of the study composite dishes. Expert peer pregnant women were encouraged to prepare the composite dishes using locally acceptable home-based methods used in their household to prepare common beans and sweet potatoes to be consumed by pregnant women.”
10. Does the study assess culinary preparation or sensory perception?
The study did not specifically target to assess culinary preparation or sensory perception. The study assessed general perceptions of motivators to consume the test food. This was explained in section 2.9.2 as “The FGDs were conducted to explore the pregnant women's perceptions to understand the factors that may motivate them to consume the test composite dish.” See line 295-296
11. Table 1 presents the two food preparation methods under comparison; however, no statistical significance tests are provided. These should be included to support the claims of nutritional or sensory benefits of the proposed dish.
Agreed: The table has been revised and now values in the same row with different superscript letters are significantly different (p < 0.05). It also shows that the iron biofortification target for the IBCB was achieved.
12. In the Results section, line 368 reports the mean age but does not provide the standard deviation. A table should be included detailing the baseline characteristics of the two groups to confirm the absence of significant differences.
Agreed: The age and standard deviation are now presented as “Their mean age and standard deviation were 24.5 years and ±2.6, respectively.” See line 343,
A table should be included detailing the baseline characteristics of the two groups to confirm the absence of significant differences.
Agreed: A table showing background characteristics of the study participants is now provided as Table 3. However, it does not show participant characteristics between the two study foods to confirm the absence of significant differences because this was a cross-over study. Please note that in cross-over studies, the study participants are switched throughout to all the treatment groups (both test and control foods). Being the same set of the participants, the advantage of cross-over studies is that patients act as their own controls. Therefore, there is no need to confirm the absence of significant differences between participants receiving either test food or control food. This is plausible because the participants were exposed to both foods. Therefore, our interest was to determine the difference in rating sensory attributes within participants, not between participants.
13. Tables 3 and 4 contain identical content. They should be merged into a single table. Furthermore, the comments presented in the results section should not be interpreted as results; their inclusion should be justified.
- Tables 3 and 4 contain identical content. They should be merged into a single table.
Agreed: Table 3 has been deleted and content merged.
Furthermore, the comments presented in the results section should not be interpreted as results; their inclusion should be justified.
Agreed, comments such as those on the nutrient composition of the study foods have been deleted in the results section. They are now shown in Table 1.
14. The discussion describes this as an exploratory study. If this is the case, the title, study design, methodology, and results should reflect this to ensure consistent interpretation.
Agreed: This was a mixed-methods study where we collected both qualitative data (perceptions) and quantitative data (sensory acceptability). Therefore, we used the word explored because we explored participants' perceptions of accepting/willingness to consume IBCB. Moreover, the word “perceptions is reflected in the title, methodology, and results. Furthermore, we use the word “determined” sensory acceptability of the study foods to reflect the quantitative data to inform whether the sensory acceptability was significantly different within participants.
15. The study’s limitations should be explicitly discussed
Agreed: The study’s limitations are now discussed under section “4.1 Study strengths and limitations.”
16. The conclusion should directly answer the research objective.
Agreed: The objective is given as: “Therefore, this experimental study determined the sensory acceptability of a low phytate: iron molar ratio dish, WFSP+IBCB (test food), against a high phytate: iron molar ratio dish, WFSP+CCB (control food), among pregnant women in rural Uganda. Their perceptions of consuming the test food during pregnancy were also explored.”
To answer this research objective, section “5 conclusion and recommendation” states: “In conclusion, we can accept the hypothesis that the sensory attributes of the low phytate: iron molar ratio IBCB served with WFSP were equally accepted as the high phytate: iron molar ratio CCB served with WFSP, suggesting that the consumption of WFSP+IBCB has the potential to replace WFSP+CCB among the study participants. Pregnant women showed positive perceptions of consuming IBCB if it was accessible, sustainable, affordable, and provided healthy pregnancy outcomes.”
Reviewer 3 Report
Comments and Suggestions for AuthorsThis study evaluates the perception and sensory acceptance of two types of foods, each with different amounts of iron and phytates, in 104 pregnant women from the second trimester onward.
This is a very real research study born from the need to meet the iron needs of a population susceptible to Uganda. Some minor aspects could improve the quality of the research.

Reviewer 4 Report
Comments and Suggestions for Authors
-
Limited Novel Contribution: While the study addresses a relevant topic, it does not offer substantial new insights. The research largely reiterates existing knowledge about iron biofortification without introducing novel methods or perspectives. More in-depth exploration of the potential long-term health benefits of the biofortified dish is needed.
-
Insufficient Analysis and Context: The article does not provide sufficient analysis of the broader implications of its findings. It lacks a detailed discussion of the nutritional aspects of iron-biofortified foods, their impact on the overall diet, and how this biofortification could be scaled or integrated into broader health interventions in rural populations.

More in-depth exploration of the potential long-term health benefits of the biofortified dish is needed.
Agreed. In the discussion, we explore the potential long-term health benefits of IBCB based on sensory acceptability and FGDs results
See line 534 -541 where we write “Findings from sensory acceptability suggest that the consumption of the iron-rich, low phytate: iron molar ratio, WFSP+ IBCB, has the potential to replace the low-iron, high phytate: iron molar ratio, WFSP+CCB, in the study pregnant women. Moreover, the consumption of foods prepared with IBCB with a low phytate: iron molar ratio has been demonstrated to improve iron status biomarkers and reduce IDA among WRA [53]. Therefore, consuming IBCB would complement other nutrition interventions such as iron supplementation and enriching the dietary diversity recommended during pregnancy to improve iron status and achieve positive pregnancy outcomes [18].
Also see lines 551 -556 were we write “Findings from our FGDs and other qualitative studies [31,54,55], inform the need to sensitize potential consumers, including pregnant women, about the nutritional value and health benefits of consuming IBCB [50,56]; Ensure a sustainable supply of biofortified foods in such a subsistence farming community through food production diversity [57], and the release of easy-to-cook IBCB varieties by the biofortification experts [58].

Insufficient Analysis and Context: The article does not provide sufficient analysis of the broader implications of its findings. It lacks a detailed discussion of the nutritional aspects of iron-biofortified foods, their impact on the overall diet, and how this biofortification could be scaled or integrated into broader health interventions in rural populations.
Agreed: These have been addressed in section 5, " Conclusion, and recommendations,” as follows:
“In conclusion, we can accept the hypothesis that the sensory attributes of the low phytate: iron molar ratio IBCB served with WFSP were equally accepted as the high phytate: iron molar ratio CCB served with WFSP, suggesting that the consumption of WFSP+IBCB has the potential to replace WFSP+CCB among the study participants. Pregnant women had positive perceptions of using IBCB if the consumption of IBCB was accessible, sustainable, affordable, and provided positive pregnancy outcomes. Therefore, we recommend that nutrition-sensitive agriculture programs should consider the sustainable growing of IBCB in this study rural district, where the majority of the study participants are subsistence farmers. Besides, future studies should investigate the acceptability of IBCB served with other staple foods (cereals, tubers, and plantains), followed by intervention studies to evaluate the effect of IBCB intake on iron status biomarkers and pregnancy outcomes in this study population.”
