depression, blood type O, and white potatoes

  1. 10 years ago

    Dear Doc,

    I am blood type O and know that white potatoes are bad for my blood type. However, I was recently hospitalized in May for 15 days for depression. The dietitician would not honor my request for a special diet, so I had to eat what I could to keep myself from getting sick. I started eating white potatoes, and I started feeling really good. My depression lifted and I started laughing and feeling wonderful, like I have never felt before. I also was doing a lot of running, and I am sure that helped. One day after eating the potatoes and running, I couldn't stop laughing. One of the guys in the hospital with me who had been getting on my nerves noticed my change in attitude. I looked at him and couldn't stop laughing. I have not felt that good since, and I wonder if it would be okay to eat some more white potatoes (I ate about three baked potatoes that day) and still stay on the blood type O diet. I do eat sweet potatoes, but they do not give me the same kick as the white potatoes did. Thanks in advance for your help.

    Hello Michael,

    It sounds as if you are getting and maintaining a "sugar high" with your increased intake of white potatoes. If this is the case and you continue to consume a quantity of potatoes necessary to keep your mood so extremely elevated, you will likely (with enough time) stress your pancreas to the point of sugar-handling problems such as hypoglycemia or even diabetes.

    On the other hand, it appears you need more complex sugars in your diet to allow you to function normally without depression. For example, sweet potatoes may not give you "the same kick," but it seems they help. Try including more of the complex carbohydrates that are acceptable for O blood types. You can always use more sprouted grain breads and related products. Just read the labels to make sure they have no added flour or other simple sugars.

    Some of the best sprouted grain breads and cereals are the Ezekial, Manna, and SunSeed brands.

  3. I get your point, and it is well taken, thank you. I have one other question. I have noticed that tomatoes keep me hyped-up, too. Not the same way, the sugar-high, I get from white potatoes. But I get excited, with a lot of nervousness. I have gotten off of them, as I used to eat them everyday. My family was raised on them, and it is something we really eat a lot of. Now I sleep better, and I am not nearly as nervous during the day as I used to be. I have noticed that I am sleeping better, too. Are tomatoes a nerve stimulant? I had read somewhere not to eat them late at night, as they would keep you awake.

    Hello Michael,

    Strangely enough, tomatoes are technically a fruit and are extremely high in natural sugars. Some people even make tomato ice cream, using the tomatoes as you would other fruits.
