A businessman moves from Thailand to pursue a job opportunity in the US. His diet changes from one high in local raw fruits and vegetables to mainly canned and frozen vegetables. The fresh produce he does buy typically ships from overseas and since it doesn't taste good to him, he tends to avoid it. Over the course of his first year, the man experiences worsening fatigue, headaches, depression and gastrointestinal discomfort, despite taking mineral supplements and making sure to stay hydrated. After about a year he meets with a nutritionist who advises him to consume more raw produce from farmer's markets; this intervention does alleviate his symptoms.
Use your knowledge from this course and the information provided to address the following:
a) What specifically about the man's dietary change likely caused his initial symptoms and why was the nutritionist's recommendation effective?
b) Why do you think the nutritionist suggested he get his produce from local farmer's markets rather than a grocery store?
c) If the man were to move somewhere with little access to fruits and vegetables, what else could the nutritionist have suggested that would have been effective and why?
NOTE: For full credit you must apply your knowledge. Just restating the information provided is not sufficient. ie. saying "he changed his diet to eat raw vegetables" is just restating the information - explain, use your knowledge and provide your logic.
a According to me the sudden change in the food habit of the businessman hs caused the initial symptoms .Because the businessman metabolism and food habit for a large time was the local raw fruits and vegetables which were exclusively found in Thailand and when he moved to US his food Habits changed drastically and suddenly to the canned vegetables and processed fruit which the US people had .Moreover when he was in Thailand his food habits were restricted to the local fruits that were available in his Village but when he comes to US the situation is changed he has now to eat what is available in US like the canned and processed items and these processed food items have a lot of chemical preservatives added in them which he is not adjusted to moreover the type of metabolic reactions used to digest the food that he ate at his Village and what he is eating now is totally different.These all things when combined together lead to the fatigue and depression and loss of interest.
b Now the nutritionist suggested him to buy vegetables and fruits from local farmers its so because it will be free of the preservatives that the grocery stores use to keep their items fresh for longer and also it will help him to get fresh produce with high vitamin and protein content than the grocery store which will several days old .
CC According to me if the man is living in place with little access to fruits and vegetable the nutritionist would recommend eating the meat substitutes like fish ,chicken or use legume like peas ,lentils etc so that he will get vitamins and proteins necessary for living an normal life .Moreover he could suggest use of milk and locally availiable fruits and vegetables.
