I was reading this article cause ive heard that some vitamins can be toxic if you get to much of them ... http://www.thedietchannel.com/Can-Large-Doses-Of-Vitamins-Harm-Your...
Every day the cron-o-meter shows that im getting about 1000-1800% of my recomented A vitamin need, 19353IU is 100% of the recommented intake, and another example is my B6 ... 5.9mg is the is 100% for a day and im getting about 450% today. Sometimes my vitamin K goes up high like this.
Do i need to worry about these vitamin intakes? should i be checking this at all on this diet?
The takeout of this article is that it includes upper limits, this is what you're looking for right?
Thank you, im gonna look at this list ! =)
im mostly worried about the vitamin A
Even moderately high doses appear to increase the risk of hip fractures.
Very toxic when taken in high-dose supplements for long periods of time.
Symptoms of overdose include dizziness, nausea, vomiting, headache, skin damage, mental disturbances, and, in women, infrequent periods.
Can affect almost every part of the body, including eyes, bones, blood, skin, central nervous system, liver, and genital and urinary tracts. Severe toxicity can cause blindness and may even be life threatening. In children, chronic overdose can cause fluid on the brain and as well as the same complications seen in adults. High consumption of vitamin A may also increase the risk of gastric cancer, osteoporosis, and fractures in both men and women.
Pregnant women who take amounts not much higher than RDA levels increase the risk for birth defects in their children. Liver damage can occur in children who take RDA-approved adult levels over prolonged periods of time or in adults who take as little as five times the RDA-approved amount for 7 - 10 years.
Cause its not like i can lower just that vitamin, i mean its coming from everything i eat
Well also B3, and B5... they all say in the long run if consumed in large dozed every day can cause damage to the body. Liver damage and organ damages. Im getting WAY above the average... like yesterday i had 42thousand IU of vitamin A when you sthould be getting 10thousand tops :S is this not worrying to anyone else?
If you start to feel something wrong, then maybe you should start checking it all. Although, if it makes you feel comfortable then you could. But I'd say keep in mind they say the same thing about potassium, and its not uncommon to be eating "too many" bananas on 30Bad. ;)
RIGHT ... i´ve heard that one before and yet all the peoples blood work on this diet comes out 100% perfect in the range :) i wast just worried cause i dont want my organs to be damadged or something in the long run cause i know not all of the vitamins you can pee out if they are to exassive.
I get the tone of what you are saying. The upper limits are real, the upper limit of potassium intake is 2500mg/kg which translates to over 400 bananas in one sitting for me to face potassium toxicity.
I really don't believe that we need much worry about vitamin toxicity on a vegan diet that does not contain vitamin supplementation (other than b-12).
When I eat a big green salad I am going WAY!!! over the daily rec... but I am also far BELOW the upper limit.
TLDR: Upper limits are real.. but very hard to get to eating whole raw foods.
i have been feeling sensitivity to bright lights(computer screen), tired eyes (soar) and headaches... i thought that was just from staying to long on the computer :/
Thank you so much Eric ! you brought me back to reality. !
haha your probably right about the computer thing Derek, i just realized i havent been eating enough calories, i´ve been between 2500-3000, closer to 2500. Drinking 3-4 l of water a day, today is day 7... and im exersicing at least once a day for about an hour, some days very intense and some days not as intense, but some day´s i go 2 times :)
Hi Karen, pre-formed vitamin A (retinol or synthetic variants like retinyl palmitate), which is found only in animal products, not plants, is indeed toxic and even deadly if consumed in excess. Foods rich in vitamin A precursors like beta carotene (produced only by plants) consumed in excess long term (something like over 100,000 IU/day) will cause your skin to turn somewhat orange/yellow, but that is the only side effect, you cannot get vitamin A toxicity from consuming plant-based carotenoids, unless you are consuming them along with large amounts of pre-formed vitamin A. B vitamins, which are water soluble, just pass harmlessly through the urine if consumed in excess, so again nothing to worry about, as long as you're consuming them from whole plant-foods. There's pretty much no risk in overdosing vitamin K either (e.g. from grapes or romaine lettuce) since the body is quite intelligent regarding how much of this nutrient is absorbed into the bloodstream. In general, the vitamins found in fruits in vegetables don't pose any health risk if consumed in large amounts, but fat soluble vitamins found in animal foods (e.g. A and D) or many vitamin supplements can either be toxic, lead to nutritional imbalances, or increase risk of certain diseases like cancer or heart disease if consumed regularly long term (not necessarily in huge amounts either). So if you're following 100% plant-only lfrv you should be fine.
Hi B.. thank you for taking your time to explane this to me. Im very glad and not worried at all anymore ! :) there had to be something wrong with this. I have to stop listening to uninformed people now :D hehe
Thank you ! :D
