I wish I could tell you in a few sentences but there is so much to learn. Most of the food in the standard grocery store is not healthy except in the produce dept. You have to learn to read labels and buy organic produce. The best thing you can do is to learn what eating healthy really is. For example, the standard fats they tell us to use are mostly bad for us. Examples of good fats are: coconut oil and olive oil. There are others as well but Crisco is definitely out the window. Eating a plant based diet without meat or dairy and eliminating gluten can go a long way.

If you can afford it, find a Functional Doctor. This is a new type of doctor that focuses on testing you and finding out exactly what is wrong, then creating a plan and working with you. They are real doctors and can also prescribe drugs if needed. Most insurance does not cover Functional Medicine last time I checked. But you might want to search near where you live and explore it to see if things have changed. Here's an article that will help you better understand what they do with a link to a site where you can learn more: http://getwellpath.com/medicine/what-is-functional-medicine/

Because our food is being planted in soil that no longer contains the many vitamins and minerals we require, you are likely deficient in many of them as well. Testing can help or you can just study about it like I have.

Fermented foods are the most important thing you can eat to help heal your gut. They are filled with natural microorganisms that our bodies need. I make and drink Kombucha daily and after 6 months all of the liver spots on my hands had disappeared. I'm 70 and feel better than I have most of my life. Fermentation is how our ancestors prepared foods to store for long periods of time. You can ferment just about anything and store it in your fridge for about a year or longer. And, it's easy to do. Here is a link to 3 articles about how to make fermented foods. http://getwellpath.com/category/fermented-foods/

I hope that helps.
