There is a growing trend of eating raw fish, which is common in the Japanese culture. Ibis is termed "sashimi" or "sushi," fish with white rice, usually eaten with salty (soy sauce) and spicy (horseradish) sauces. This can be a very nutritious and low-calorie meal, but the Ash must be fresh and clean, as bacterial and parasitic contamination can lead to sickness in the consumer.
More commonly, baked or broiled fish with seasonings and lemons, often with some oil or butter and garlic or other herbs, is probably the overall best. Steamed or lightly sautéed fish can be very good. Fried fish and especially breaded fried fish should be avoided because of the high content of fat, calories, end salt, none of which are good for us in excess. Besides, the hydrogenated vegetable oils or polyunsaturated oils are difficult for our body to process, and thin can lead to other problems.
For weight loss, fish and vegetable meals are ideal, without extra oils, carbohydrates, or breads, of course, and no dessert. Fish with rice or pasta and vegetables, often cooked with the special flavors of garlic or onions, is a good balanced meal. (For weight watching and proper food combining, have just the fish and vegetables.) Shrimp, tuna, or sardines added to a salad with lots of greens and other vegetables is a very wholesome, healthy, and filling meal. I'm hungry; I think I will go make dinner.
