People often ask me, what should I eat to be healthy, or what is the best diet? People vary in their physiology. I lean more toward a higher protein and lower carbohydrate "diet".
To make it simple, most of the healthy diets out there are basically what I've been saying for the last 20 years. Eat "REAL FOOD"! Real food is basically, FRUIT, VEGETABLES AND HEALTHY PROTEINS. Fruits should be low glycemic index fruits like rasberries and blueberries which pack a lot nutritional bang for your buck. Low glycemic index vegetables like your dark green leafies. You should eat a salad a day and make it with as many colors as you can. Fruits and Veges are best raw. They are alive and provide you with beneficial enzymes. You destroy a lot of the nutrition when you heat/cook them. Proteins should come from as much a natural environment as possible. Remember, you eat what they ate. So avoid bottom dwellers and garbage eaters. Wild Caught Alaskan Salmon, the best and is loaded with omega 3 fatty acids. Grass fed beef and pastured poultry are other forms of healthy proteins. Buying local is best. Here is PA, we have access to the Menonite and Amish farmers. Our friends in Bloomsburg at Wild For Salmon go to Alaska every summer to fish for Wild Salmon.
On the otherside, avoid processed, boxed, canned, prepackaged and fast foods. The longer the shelf-life, the worse it is for you.
westonaprice.org and "Nourishing Traditions" by Sally Fallon are great resouces for information on healthy eating, where to find it and how to prepare it.
