If you want to get the best out of your nutrition you need to keep track of what you are eating. In this day and age, that is very easy to do with your smartphone. Some people also need to get ideas of recipes to cook that are healthy and easy to make. You can use your smartphone for that too.
The best app out there, in my opinion, for tracking what you are eating is definitely MyFitnessPal. It tracks your total calories, grams of protein, carbohydrates, fat and sugar as well as milligrams of minerals such as calcium, potassium, and sodium. What is the most impressive about MyFitnessPal is that it already has all the nutrition facts about almost every food from every manufacturer out there and, if by chance you can’t find what you are looking for, you can add it in yourself. This app will also automatically sync with your computer so you can also use the MyFitnessPal website on your computer to add and check everything you have done on the phone app. The last great thing is that if you are big into using the iPhone HealthKit app, MyFitnessPal and HealthKit will automatically sync with each other so that you can track all of your nutrition data in an easy organized way that anyone can understand.
If you are looking for a good app full of healthy recipes, you no further than Yummingly. Yummingly is an app full of healthy recipes of all different types of food with all the nutrition facts you need to know. Also, just like MyFitnessPal, you can sync all your nutrition data from recipes that you have chosen and sync them with the HealthKit app.
Beyond these two apps, there are literally hundreds (if not thousands) of others that you can try but these are easily my two favorites.
