Food intolerance is a pharmacological reaction to the consumption of certain foods. In many cases, food intolerance may appear to be the side-effect of pharmacological drugs, but in fact, it is generally caused by the consumption of natural foods products, additives, or the combination of both.

The majority of food products that commonly cause food intolerance are high-protein.

As a low carb dieter, you will have abnormally- high exposure to high-protein food, including dairy products and meats, which means your chance of experiencing food intolerances (if you have any) will increase.

In contrast to food allergies, which are easily identifiable because they affect an almost instantaneous reaction of hives, shock, and a range of other symptoms, food intolerances are somewhat harder to identify.

Food intolerance generally has milder affects, such as minor headaches, general irritation, upset stomach, restlessness, and a loss of sleep. This makes it much harder to identify and treat.

If you are new to your low carb diet, you may have already experienced some of these symptoms, but attributed them to something other than food intolerance.

If you have been exhibiting these symptoms for less than three days into your low carb diet, they are more than likely related to withdrawals from caffeine or carbohydrates. They could also be related to dehydration. Conversely, if you have been exhibiting them for more than three days, they are more than likely the result of a food intolerance.

You should immediately start the process of weeding out foods that could be causing the intolerance.

The following is a list of foods you may be consuming on your low carb diet that are likely perpetrators: eggs, nuts, milk, fish, shellfish, pork, bacon, chicken, cheese, and tomatoes.

You should try to remove one of these from your low carb diet at a time. If you cannot solve your intolerance problem within a week, it would be wise to get off of your low carb diet and contact a physician to determine the source of your intolerance.
