Not a web site, but a book.

Eating On The Wild Side by Jo Robinson

She looked at hundreds of studies of how we get nutrients from food – about which foods are best and how to prepare them best. And she turns it into useful advice.

She gives advice on doing the best you can with what you can actually find in your local grocery store.

Calorieking.com is pretty good.
If your looking for a plan Weightwatchers.com is good but there is a fee.

What information do you want specifically? Calories, sodium, fat, cholesterol? A lot of sites have that. If you want vitamins and minerals in detail I have never found a good website for that. I have a nutrition text book that has everything. It has whole foods (foods we buy and prepare ourselves) another section with packaged foods, and a fast food and restaurant section. I don’t know the name of the book, because it is in a box right now. Doesn’t matter, if you go to a bookstore you can probably find something with that info. Or, you could also go to a college bookstore and look for a text book. I guess some text books are online now. I google things like, “vitamin K foods,” or, “high protein vegetables,” to get information to help steer what I eat.

I care about cholesterol, calories, protein, and vitamins and minerals. The calorieking website @Judi supplied looks good for the basics, especially for calories and fats.

The other site that is kind of like a community with a lot of diet options and groups of people all working towards the same goal is sparkpeople.com. Oe nice thing there is that you can join a group of people who are doing the same diet as you. It’s a pretty large community and they have points you earn for showing up every day and tools to monitor your progress. It’s free.

The reason you get different information from different people is because not everything works the same way for everyone. Take the Atkins diet for example – people swear by it, they’re loyal to it, and it does work. However, you’ll also find research that states it’s not healthy for you. I lost 40 lbs on Atkins, but I’d never do it again because it made me hate so many different foods that I ran out of things to eat. Plus, there’s no logic in being able to eat a plate of bacon but not an apple because of carb content. I swore off of low carb for this reason.

Then you’ll find the people that swear they can’t lose weight if they eat more than 1000–1200 calories per day (resisting the urge to call BS on that one), and a whole other camp of people that say 1200 calories is the absolute lowest you should eat and still isn’t sufficient for someone that isn’t a very petite, inactive female. And you’lll find research supporting both points of view!

Here’s another one: vitamins. Are they useful, necessary, or completely pointless because you’re just peeing all of the nutrients out anyway? Again, you’ll find research supporting all of those viewpoints.

My point is that you need to find what works best for you. There’s no one website that will contain everything you need to know.

I’d second @livelaughlove21‘s viewpoint. I had to tailor a diet that worked for me not as a means of losing weight but as a lifestyle change. And it had to meet my body issues and the way I wear excess pounds and how I metabolize food.

I have an “apple” body, meaning anything more than about 20 BMI goes right onto my belly. Other than normal spreading weight all over, when I am overweight I don;t get thick thighs or ass, I get some extra in the upper chest and shoulders, but nothing that looks unusual. But I get a nice round tummy. Reading up on it, I had to analyze the way my body places fat on my abdomen, how my body metabolizes sugar and converts any simple carbs and also most complex carbs into sugar, and then takes fat and stores it on my abdomen.

Other people’s bodies are much different from mine, and will respond differently.

And, @LDRSHIP, you are always looking how to improve your strength, which is much different from those of us who are losing or lost weight.

Try Myfitnesspal.com it’s a pretty good site.

@JLeslie Mainly how different amounts of specific things will change your body.

@livelaughlove21 “Plus, there’s no logic in being able to eat a plate of bacon but not an apple because of carb content. I swore off of low carb for this reason.”

I’ve decided to stay from any “fad” diets or ones that cut out something 100 percent often it ends badly in the long run.

“Then you’ll find the people that swear they can’t lose weight if they eat more than 1000–1200 calories per day (resisting the urge to call BS on that one), and a whole other camp of people that say 1200 calories is the absolute lowest you should eat and still isn’t sufficient for someone that isn’t a very petite, inactive female. And you’lll find research supporting both points of view!”

Yes exactly this why I am interested in more truthful and factual information on the effects of certain nutritional values on a person. From what I’ve learned the diet needs to be tailored to the person’s lifestyle and goals.

“Here’s another one: vitamins. Are they useful, necessary, or completely pointless because you’re just peeing all of the nutrients out anyway? Again, you’ll find research supporting all of those viewpoints”

I don’t know much about it, but apparently lacking certain things or eating certain things can block the absorption of them. Or take too much of it and body dumps leftovers which some supplements are overloaded with.

Which in the end is the point I was trying to get at or ask. I don’t want a gimmicky bullshit diet or something. I want to know the real science behind it. A lot of these big websites I think are just in it for the market because hell…It sells! America buys bullshit, even I do unfortunately I learn the hard way sometimes.

@zenvelo I like your approach and thought process on it. I am experimenting to a degree, but with healthy alternatives.
