Nutrition and Health: Food Risks

Wageningen University via edX

Overview

Everyday reports of food scandals and recalls are published. One day it's scary bacteria in meat, and another day it's dangerous pesticides in fruits. According to some, meat needs to be cooked well to prevent food-borne illness while others warn not to heat food to prevent the formation of poisonous substances.

Many consumers worry about the conflicting and confusing messages about food hazards

This nutrition and health course will teach you about the hazards associated with food and give you the tools to assess and quantify the dangers they can present. You will learn the effects of food processing, the shared responsibility in the food chain and the prevention of food poisoning/intoxication. After this course, you will be able to differentiate what is a food myth vs. an actual risk. Finally, you will gain a contemporary view of how different risks can be weighed in a scientific way.

    Since I was auditing the course I found some of the science and math difficult to follow in the time I desired to spend on the course. I did learn a lot of helpful things that I have already put to use in determining the purchase and use of a new food product. I felt the course was well organized and the speakers were informative. As with health care and taking medications there are a lot of risks the consumer must consider before deciding on consuming foods. We assume everything that is sold to the public is totally safe, which is not true. Learned many good tips on the selection, storage, and preparation of food products. Thank you.

    The course is very interesting although it presents many technical topics not immediately understood. It would be useful to have a synthetic pantry that summarizes the various methodologies and procedures in risk assessment

    The course is very well constructed. The information is well presented by the staff and the interactive materials are good. The commitment of the staffing team and presenters make the course more interesting and engaging, and encourage participants to explore more knowledge on related topics. The info learned from this course has been very useful in improving food safety in our daily life, our family food hygiene and useful info to be shared with friends so that more people are aware of food safety and do better together to achieve a safe social environment with less food risks and hazards. This is a great course for everybody.

    It was a great course - I learnt heaps of stuff from food safety, nutrition and the associated practices in the industry. Segmented parts of the course made it manageable to progress through the course. There were also several interesting videos to support information in the course. Practice questions in the course (with also answers provided) enabled application of the newly acquired knowledge too. There is also a myth debunker! Nevertheless, it is a course suitable for refreshers (for those who have taken Food Safety course(s) previously), industry workers, and definitely students who want to learn about Food Safety and etc.

    I'm so happy to be a part of this course. It is being a part of my daily routine and is increasing my knowledge day by day.The animations mainly are giving a clear view of the chapter. The ungraded questions are also very helpful for self assessment about the course. They are helping me to analyse how far i have understood my course. All the professors have done a great job in investing their valuable time by making videos and the best part of the video is providing subtitles so that every person has understand it .I would like to extend my heartful thanks to each and everyone for providing students this platform.

    This course is very useful. The topics are highly appropriate when considering the course topic. The teaching staff is very talented and the way of teaching is very attractive. Videos, audios are also in very good quality. Because of the great explanations about the lessons, easy to understated. Food Myth was a attractive lesson. At the end of the course I was able to collect lot of new information with related to the food safety. This course can be followed without any boring. As a student who has completed this course, I highly recommend this course for any on who is interested with food safety.

    I just recently finished this course, without taking the exams and assignments as I am only using the audit access and here are my thoughts:
    - The MOOC is easy to understand, well-explained, and precise.
    - It is very useful and essential as it is aligned to my subject regarding food safety and microbiology in my nutrition program.
    - All videos are very nice. It feels like you are taking a classroom lecture virtually.
    - Lastly, I really enjoyed the experience of using an online course as it is the first time that I have been completed.
    Keep up the great content! :D

    The MOOC had very comprehensive and enjoyable content, covering a wide range of risks related to food. Nevertheless, it is my personal opinion that the course should be more focused on industrial implementation. It must be highlighted that the instructors were great professionals, with experience on the field and this made the mooc much more interesting. The way the information is given was well structured and the self-paced base made it feasible to everyone, even for individuals with limited time. Hope there will be other MOOCs such this available in the future to join.

    Overall, I am completely satisfied with the course. The videos and material were very well presented and organised in an playfull, amusing and not tiresome at all way. I was very pleased to get familiar with chemical risk assessment, as I have never done it before, and specifically that course was explained in detail. Nevertheless, personally, I would like to learn more about implementing microbiological risk assessment in a practical level, as well as, how risk management is applied at a risk analysis.

    My experience through this course was pleasant, since I did not know about which dangers were avoidable and unavoidable, also calculating the MOE, TDI, ADI to see if it represented a concern or not, also knowing the ways in which they are reduced the dangers. The myths of the week was an important part in each module since many myths had not made me think about those. There were many new and interesting topics for me. Very good job to the people who took this course. Thanks for everything.

    I think this MOOC is well done, it provides you with a lot of info regarding different subjects. I would have appreciated more to have the chance to download more full articles (some of the additional material links are pay per view access). Also more examples would help understand some argouments (like different practical cases in which responsibility is exerted by different actors in the food chain).
    Anyway, overall I think it's worth taking this course!
