What food should I avoid

1) "In general terms, the healthy eating pyramid recommends the following intake of different food groups each day, although exact amounts of calorie intake depends on sex, age, and lifestyle:
Daily exercise and weight control
At most meals, whole grain foods including oatmeal, whole-wheat bread, and brown rice;1 piece or 4 oz.
Plant oils, including olive oil, canola oil, soybean oil, corn oil, and sunflower seed oil; 2 oz. per day
Vegetables, in abundance 3 or more each day. Each serv. 6 oz.
2-3 servings of fruits; Ea. serv. = 1 piece of fruit or 4 oz.
1-3 servings of nuts, or legumes; Ea. serv. = 2 oz.
1-2 servings of dairy or calcium supplement; Ea serv. = 8 oz. non fat or 4 oz. of whole.
1-2 servings of poultry, fish, or eggs; Ea. serv = 4 oz or 1 egg.
Sparing use of white rice, white bread, potatoes, pasta and sweets;
Sparing use of red meat and butter."

You should make some modifications to this if you are a vegetarian (I am one).


2) "Avoid or use in moderation the foods below:
- Solid fats --from land animals
- Trans (partially** hydrogenated) & most deep fry oils.
Sorry: 99% of commercial fries [see end of page] and 90% of chips, shortenings and margarines.
- "Vegetable" oil: corn, sunflower or undefined industrial types. The "white" -factory denatured- oils.
Fine are: virgin olive, canola, lin/flax & unhydrogenated soy -if you can't find canola- and mustard oil.
- Flour (white - refined) and flour-made pasta. The more finely ground the flour and the more boiled [less al dente] the noodle, the higher the "glycemic index" ... not a healthy thing.
- White rice -the more "whole", the better.
- Sugar
White, brown, "glucose-fructose", molasses***, corn syrup & most soft drinks
- Dairy
Not everyone puts it in the avoid group but it's a food with complications: NotDairy.com "

You didn't say why you should avoid food in the first place. However, if you think you have any intolerances try cutting out specific food groups one at a time. Normal culprits are dairy, yeast & wheat but there are many more. If you are trying to lose weight then limit intake of 'unhealthy' foods. List are readily available via the internet.
