Wellness Project
Hello readers, here is my wellness project slides. I think it went quite well because I got some of my friend's feedback on google forms for my presentation and speech and got quite good results. It worked out quite well, and I hope in the future everyone will use these fitness tips. Thanks!
Pellagra
Here are the answers to the "Pellagra" questions.
1a. He observes first hand where the severe cases of the pellagra are. He then visited a prison with lots of cases of pellagra. This helped him to develop his hypothesis as he found all the people getting pellagra were poor and had a terrible diet.
1b. He found that in orphanages and prisons only the kids and the prisoners contracted pellagra, not the teachers from the orphanages or the staffs from the prison, so it couldn't be caused by germs as they do not know of status boundaries.
2a. His hypothesis about the cause of pellagra was that it was caused by a lack of vitamins, like scurvy.
2b. He conducted an experiment on 11 prisoners. Before the experiment, the prisoners were eating fruits and vegetables from the prison garden. Goldberger started feeding them only corn and bread, and in the end 7/11 of the people that ate corn contracted pellagra, but when the prisoners were allowed to eat fruits and vegetables their pellagra healed. This provided evidence that proved his hypothesis as when he took away vitamins, the inmates got pellagra, but when they had vitamins (fruits and vegetables) again, they got better.
2c. He could have provided more information like telling the people at that time what particular vitamin, when lacked, caused pellagra. This would have acted like a "medicine" and people would have believed in it more. Or, he could have said people need to have a lot of vitamins to cure pellagra instead of saying that it was caused by a lack of vitamins.
5. I think this was a bad idea as conducting the experiment on humans would actually be quite cruel and sometimes might get the people in the experiment insane and confused. They would also suffer a terrible 6 months of their life suffering pellagra because of the diet. I would only try to give it to one person that is willing to suffer pellagra for science's sake, or just give it to another animal entirely. This would be a lot better as not so many humans would have to contract the pellagra disease.
