Hm - pure nutrients, vitamins and minerals should not have any negative effects at all.
What I mean by that is that you can take all vitamins, minerals (except iron which should not be taken as a man at all) and nutrients.
But of course if you take for example Omega 3 supplements with certain oils - GMO soybean oil, then of course it may have other effects, but that is just based on a specific set of foods.
For example - I am taking Lecithin and avoid lecithin from soy, but pick sunflower lecithin. You pay only a bit extra.
There are a multitude of things that impact your body negatively and should be avoided - some at the top of list at all cost:
+ Artificial Sweeteners - Splenda, Sucralose, Aspartame etc.
+ MSG - taste enhancers - KFC secret ingredient
+ most vegetable cooking oil at higher temperatures - use coconut oil, clarified butter, lard instead
+ soy ingredients - soy lecithin found in many foods, but they are using it also as a regular in feedlot foods - especially chicken and pork is thus highly tainted with stuff like that - not only the antibiotics that those animals have to take
+ HFC high fructose corn syrup - highly negative for your body, impacts your hormonal household like most other of the stuff on the list - way more negative than white sugar which ais also not healthy, but HFC is a couple steps up on the scale
+ avoid cheap chicken, cheap pork, cheap salmon - switch rather to beef which is still relatively good in Europe even if bought cheap, otherwise organic meat is not that expensive - better eat less of it, but higher quality (in EE you can buy a pound of organic beef for 5-6$, in the UK it is closer to 45$)
Aside from that sticking to the known rules of nutrient density (easily achieved via good supplements) combined with low calorie intake and avoidance of the list of foods above - then you will be fine. That means in return that you probably cannot eat in many restaurants often, then so be it.
