Too much of a good thing: it’s a well-known fact that when we indulge in certain products a little bit too much, there can be consequences. It's a rule that applies to pretty much everything in life, but when talking about food it rings particularly true. As it turns out, eating too much of certain foods can actually increase your risks of developing cancer and diabetes. So if you want to regulate your diet, it’s worth knowing what they are.Meat and grilled foodsMeat such as chicken, beef, pork and even fish are grilled or fried at very high temperatures. They release heterocyclic amines as well as polycyclic aromatic hydrocarbons which affect the DNA and increase your risk of developing cancer. On top of this, red meats are also known to cause an excess of cholesterol in the body.Sugary foodsAs well as being very high in calories, sugar can cause a surplus of triglycerides which are normally produced by the liver. Once they are in the bloodstream, these triglycerides can get stuck in your arteries and clog them up, consequently leading to heart problems. Often times, it's not the overly sweet food that we need to look out for here, but sugary drinks.Ready meals and convenience foodsApparently, meals that have been made in a factory cause a lot of serious health problems (but we could have guessed that already). According to a study, people who exclusively eat ready meals are expected to consume more calories in a given day than a normal person would. Not only are calories the problem, but all the other 'invisible' additives that we don't see go into the preparation, like forms of sweetener. When possible, opt to eat meals that you prepare yourself so you know exactly what you're putting in your body.AlcoholNot only is alcohol abuse dangerous short term, but also long term. As it turns out, as well as making you gain weight, drinking too much alcohol can also lead to several types of cancer.
