I was wondering on a few things which hopefully can be answered.1. I usually never drink/eat soda/junk food, but once in a long while I will have some and eat very sparingly, like if I have a 6 pack of soda, I will drink one a week. Is this still bad for my diet? I excersize daily so I don't think they will affect me, but seeing how much people talk so much about not having soda/junk food, it made me wonder.2. What does taking vitamin supplements actually really do? I have never taken any because I kind of think of them as a "steroid" and I've never bothered to buy/get some from friends. I've heard they allow muscles to form faster/more, but my sources may be wrong.Thanks
Questions on drinking sode and taking vitamin sup
Very occasional sodas or junk food won't hurt much - the difficulty for most people is stopping at "very occasional".Vitamins are not steroids. There is controversy over vitamin supplements. Nutritionists generally consider that if you are eating healthily (and of course many people aren't) you should be getting enough vitamins in your diet and shouldn't need supplements. This assumes that having more vitamin than is needed to prevent deficiency disease is of no value, and this is where the controversy lies.It's certainly true that too much Vitamin A is toxic. It's hard to get toxic levels of Vitamin A from diet, but people have died from eating bear's liver which has very high levels of it. Too much of water-soluble vitamins like C or the B group is just excreted and is not toxic. Some people claim very high doses of Vitamin C is beneficial, but there's not much evidence for it. There are recent suggestions that we could benefit from more Vitamin D than we usually get, and E has been touted for a long time.If you are building muscles you may have heightened needs for some vitamins that are involved in producing tissue. Folic acid (folate) is a particular example. Pregnant women are often urged to take folate supplements, and bodybuilders may have similar need of it.Essentially, normal supplements won't harm you, but if you are eating healthily they won't have any dramatic effect.
