Problems with sweet potatoes-it has been deadly to cattle

Answered on April 02, 2014

I see people here like sweet potatoes a lot. Its though to be much lower in toxins than white potato and cassava. But there is something with sweet potatoes that been whipping out cattle when its been used for feed. You can google it and find a lot of information.

The problem seems to be if the sweet potatoes get bruised or damaged or blemished they start to produce a very potent toxin, one of them is ipomeamarone a liver and lung toxin. I found a book where a survey of that toxin in supermarket sweet potatoes was compared and in one specimen from Lexington,KN it was extremely high, at 7-6 mg/g. That means an average sweet potato had 950 mg of that toxin, quite close to some LD50 (a dose at which 50% of animals die) doses in animals?? But there are almost no studies on this. I feel we just dont know enough about this and if sweet potatoes are really safe.

Lol, sweet potatoes definitely do Not contain Vitamin D: https://www.google.com/search?q=sweet+potatoes+vitamin+d&oq=sweet+potatoes+vitamin+d&aqs=chrome..69i57j0l5.4197j0j7&sourceid=chrome&espv=210&es_sm=93&ie=UTF-8 .

Well, I eat pretty much everything. If I am too tired to cook or something I even grab cookies or anything from wheat.

That would be the book name, not an article. In the lower doses ipomeamarone is not an instant killer, but since it attacks the liver and the lungs, it could be that someone can get liver cancer from lower doses.

If you are really careful when buying it, that it is perfect, and cut 10mm around any blemish its probably Ok.

The word you're looking for is orthorexia, not speculation. You know that paleos ate them don't you? Nightshade too. Don't let optimal be the enemy of omnivorous.

The article is titled "sweet potato an untapped food resource", not "sweet potato hidden killer".

Regardless… if you don't eat spoiled sweet potatoes there's little issue. We don't feed humans rotten food, though some folks feed livestock rotten food.

You said Google it, there's a lot of information… then you link to 197 of a scanned book pdf from 1992… can you say obscure?

I'm curious. ^^

Of course potatoes are nightshades, and do produce toxins. Normal potatoes will produce toxins when they go bad as well - solanine - which concentrates mostly at the skin level of the potato.

Sweet Potatoes are really helpful. I have no doubt in my statement because of following reasons:

1) High Vitamin B6:

Vitamin B6 helps reduce the chemical homocysteine in our bodies, which helps in prevention of heart attacks.

2) One of the good sources of Vitamin C:

Vitamin C helps in increasing immunity against cold and flu viruses. Produces collagen, which helps maintain skin’s youthful elasticity.

3) Vitamin D:

Sweet potatoes contain Vitamin D, which is critical for immune system. Vitamin D plays an important role in our energy levels, moods, and helps to build healthy bones, heart, nerves, skin, and teeth.

4) Sweet potatoes contain iron

Iron plays other important roles in our body, including red and white blood cell production, resistance to stress, proper im­mune functioning,

I did read it, it says evidence about cooking reducing it is contradicting. In one part it says if you cut 3-10mm you will significantly reduce the toxin, in one part it says the toxin with time infects the whole root. 10 mm is quite a lot to cut.

Its weird about sweet potatoes,you can feed the cattle rotten and moldy white potatoes, you can feed them rotten vegetables and none of them kills them like sweet potato does. My worry is that the low levels of this toxin could be causing things like liver cancer, over time.

But this is all just speculation.

Did you read the entire section you posted in the pdf?

Cut off the offending portion of the SP, also cooking removes a large percentage of it. I always avoid the odd looking parts if any, and cut them off before cooking if I see them. Most of the ones I buy are in good shape.

There are millions of studies to be done on various foods, etc. If you stop eating all foods until the final results are in you will die of starvation.

Oh, the potatoes they used in the survey were not moldy. They were common potatoes people buy and eat. They mention they were slightly blemished.
