Reviewer 2 Report
This study is well designed. However, the following points should be improved before publication.
L4: What is “PURE study”? Full name of “PURE” should be incorporated.
L17: “inaccurate assessment” What do you mean?
The following issues in this study should be considered in the discussion.
L27: Replacing total fat with “carbohydrate”:
How about starch? or sugar (sucrose)?
L105-107: How about cholesterol contents of fats?

Reviewer 3 Report
In this comprehensive study, the authors assessed patterns of dietary fat intake in a large cohort of adult Chinese population, explored the association of various dietary fats with blood lipid biomarkers and compared the results with other relevant research.
The study is well designed, the results are clearly presented and the discussion is supported by the results. The study is of importance for the field.
Specific comments:
Statistical analysis: this section should be complemented by more detailed description of residual energy adjustment method (results presented in Table 3).
Selection of adequate clinical trials for comparison should be presented in details.

Reviewer 4 Report
The study presented to me for review by Rongping Zhao et al. was designed to assess the profile of fat intake in the Chinese population and comprehensively examine the associations of fats with lipid biomarkers across different types and sources of fats.
The introduction although brief shows a research gap, which the authors decided to exploit in their study.
The material and methods chapter is described correctly. A flowchart of the study's sample selection would have been helpful to improve the perception of perception.
In the study, the authors clearly and logically formulated the objectives of the study, consistently carried out the tasks set, and presented balanced conclusions. There is nothing left to do but congratulate the authors on a well-invited and well-designed survey.
From the technical notes, please only change the way of citation according to ACS style and put references in square brackets.
