Skip to 0 minutes and 14 secondsHello, and welcome back to the last lecture of this course. Maybe you were expecting us to discuss the benefits of red berries and salmon, of quinoa and amaranth. We did discuss some superfoods such as green tea, berries, chocolate, and buckwheat but many lectures focused on what a superfood is not. They are not medicine and they will not prolong your life.
Skip to 0 minutes and 43 secondsAs we said in other occasions, this doesn't mean that all is lost because of the market niche they occupy and because of the way they are produced and sold, superfoods tend to be healthy foods and are likely to be fruit and vegetables.
Skip to 1 minute and 3 secondsAfter all, superfoods can be good for your diet. Adding sprouted beans, goji berries, seaweed, and juicy strawberries to your diet will increase the variety of what you are eating and in a way, few nutritionists would object about. If the health claims will be determined to be true, they will be a nice and maybe unexpected bonus. Going back to this course, there are other things that maybe surprise you as finding an article on LDAS or a lecture on nutritional composition databases. Though not exclusive to superfoods, these are elements that will be able to guide you in all dietary choices. We hope that they will come back to your mind when you are picking the next food or the next superfood.
Skip to 2 minutes and 1 secondIn any case, thank you for remaining with us until now and we hope to see you in the future in some other course.
Conclusion and goodbyes
What did this course talk about?
In the last four weeks we reviewed topics linked to superfoods: we started by defining what superfoods are and what they are not, as well as by discussing associated concepts: probiotics, prebiotics, antioxidants, nutraceuticals…
We then continued by showing you some alternatives to superfoods, as well as a way to find your own superfood alternatives, and by discussing some issues linked with gluten-free diets and the characteristics of an “ancient” grain: buckwheat.
We then moved to the third week and to its main topic: flavonoids. Flavonoids are very widespread in the vegetable realm, but some superfoods are particularly rich in them: for instance chocolate, green tea and some berries. Flavonoids could improve our health through different mechanisms: they could fight oxidative stress and improve our cardiovascular health, but more research is needed before we can say that some specific foods can be used as a medicine or a preventative measure.
Finally, in the last week we discussed some negative aspects that could be linked to superfoods: are they always safe? Are the antinutrients contained in some of them bad for our health? Can they cause allergies like regular foods?
We hope that in these four weeks we gave you some food for thought, as well as some tools to reflect critically about superfoods and their role in our diet. Most importantly, we hope that you enjoyed this course and the discussions with your fellow learners and the instructors.
