How accurate is Fitday.com?

I've been using Fitday to track what I'm eating for the past week. How accurate do you think the nutrition information is? For instance my profile today says that I haven't hit the RDA for iron among other things. This is despite having eaten a 10oz rump steak for tea. This seems unlikely to me. I seem to consistently come out low in potassium, thiamin and magnesium. Does this mean I should be supplementing? Or should I be adding something to my diet. I'm strict paleo at the moment so no nightshades or dairy, and very little fruit (odd kiwi). Should I ignore the nutrition information and just look at the calorie breakdown? (averaging 60% fat - yeh!!)

after using fitday on and off for the last six months or so I finally made the jump, at a paleohacker's mention, to LIVESTRONG. the site's opinions regarding nutrition is goofy but their calorie-tracker i've found is much easier and effective than fitday's.

I've found that it provides reasonable estimates and it's certainly useful to have some data available, especially if you have to argue with doctors. I've created a lot of custom foods too. I also don't pay too much attention the RDA values.

I totally agree. I used Fitday for four years to lose weight. I always considered it a good estimate, but not 100% accurate. I don't think anything really could be. All of those programs use estimates. Fitday is as good as the rest.

I used Fitday to help me see where I was as far as carbs and fat were shaping up in my diet. I didn't worry too much about the vitamins and minerals, as it is hard to accurately estimate those things depending on your food. A piece of grass-fed beef probably has different nutrient levels than a piece of grain-fed beef. I wouldn't concern yourself too much with the counts for vitamins and minerals on Fitday. If you are really concerned about those things, take a good multi-vitamin and you'll probably be fine.

Plus, the absorption of the vitamins and minerals change depending on what you are eating. Fitday doesn't concern itself with how those things work in our bodies related to our diet, it's just a tool to help.

I think it gives a fairly good estimate, but the accuracy also depends on a few factors such as: Are you weighing your food? If not, then the results will obviously be much less accurate.

Also, there's no way to be 100% accurate regarding the nutrient content of any given food, especially "paleo" foods such as meats, veggies... because their nutrient content relies a lot on how the food item was grown and cultivated, quality of the soil, quality and type of feed for animal products, conditions in which the product was produced, and of course cooking method (if any), etc.

In my opinion fitday is a good tool that will give you a decent idea of what you're consuming but I wouldn't get too stuck on the accuracy of it all.

I signed onto fitday and tried to set a weight goal of 165 lbs (i weigh 145) and it said "error: goal weight is higher than start weight"

closed tab after that silly remark

I'd consider vitamin intake on a case by case basis depending on the vitamins. Some vitamins, like E are controversial as to how important they are, such that the RDA may be too hjigh Some, like vitamin D, are controversial in that many feel the RDA is too low. Many find that it's hard to meet the magnesium RDA on any diet, but especially if you aren't eating potatoes, which are a main source for many people. HOwever, personally, I feel the magnesium RDA may be accurate as a good intake level. Other RDAs that are often low on paleo are calcium (if no diary) and E. I am not sure how impt calcium is as on the one hand, calcium absorption is better when D levels are higher, but on the flip side, paleo eaters probably consumed a lot of small bones, something most of us don't do anymore. If you are low on a vitamin you consider impt, your options are to purposefully eat more foods with that vitamin in it, or research good quality supplements for that vitamin.

Fitday is not accurate regarding vit K. I entered all the highest vitamin K foods available and the program calculated "zero" vit K. I have not used fitday since but do not have a good alternative.

I found that Fitday continuously calculates more carbs for veggies than they actually contain.

I use Fitday mostly to keep track of my macronutrients (fat, protein, carbs) and weightloss. I haven't paid much attention to the micronutrient since I noticed it said I was getting 300% of the RDA of saturated fat and cholesterol.

I feel RDA is very high. It was intended to meet 97% to 98% of American's need. These factors affect your nutrition needs: 1- Smoking, drinking. 2- Your weight. 3- food mix. 4- coffee, tea, soda 5- eating on empty stomach 6- mood. 7- exercise 8- how much water you drink if you meet 35 % of RDA for Vit E, 35% of Vit A Rda, 50% of folate RDA, 50% Vit K RDA, 50% of Vit C RDA, 50% Vit B6 RDA, and 75% of other RDA then you are OK. NO One can meet RDA

the RDA does not mean too awful much on most of this stuff, you need to know what actual numbers you are after, I use Livestrong.com, i hit 800+ percent of the cholesteral RDA almost daily, usually 400+ percent on protein too.
