Hydrogenated vegetable oils, which we just discussed, is essentially what fried foods are traditionally cooked in. While fried foods are being cooked, they are soaking up all of the unhealthy fat in the oil they are in. When consumed, individuals are placing increased strain on their heart as plaque begins to build in their arteries, forcing their heart to work harder to pump blood. When foods are fried, they also lose their nutritional value. This means even otherwise healthy fish will not be nearly as good for individuals when they are fried, which is how they are typically cooked for traditional fish and chips. It is especially important for individuals who already suffer from a health condition to eliminate fried foods from their diet.
