Foods to avoid when taking Colchicine
A diet low in purines can not only prevent the symptoms of diseases associated with elevated levels of uric acid in the blood but also improve overall health and well-being.
Purines are organic compounds that are part of nucleic acids and other important biologically active substances. In the human body, the end product of purine metabolism is uric acid. Disorders of purine metabolism can lead to increased levels of uric acid in the blood – hyperuricemia.
A diet low in purines can not only prevent the symptoms of diseases associated with elevated levels of uric acid in the blood but also improve overall health and well-being.
Gout patients should avoid excessive intake of alcoholic beverages, especially beer. Moderate consumption of wine is not associated with gout exacerbation. Excessive alcohol consumption leads to more frequent gout relapses, even with allopurinol therapy.
Patients should avoid drinks sweetened with high fructose syrup. It is also important to limit natural sweet fruit juices, table sugar, sugary drinks and desserts, and table salt. Grapefruit and grapefruit juice should be avoided when treated with Colchicine.
Foods containing high levels of purines include:
- red meat and game;
- certain seafood including: tuna, sardines, anchovies, herring, mussels, cod, scallops, trout, and haddock;
- meat by-products (kidney, liver, heart, etc.)
- legumes (peas, lentils, etc.).
It is recommended that these foods be significantly limited or avoided:
- High-fat foods.
- Alcohol. Beer and whiskey are particularly high in purines. Alcohol also causes dehydration, which makes it difficult for the body to eliminate uric acid.
- Sweetened beverages: Fructose is an ingredient in many sweetened beverages, including fruit juices and carbonated drinks, and its excessive consumption is accompanied by a risk of developing gout.
Maintaining a high level of hydration by drinking plenty of fluids can be helpful in preventing gout recurrence. Since the association of gout with the development of atherosclerosis is well known, a diet low in cholesterol and fat is advisable.
Meals for gout should be fractional, the number of meals a day – from 4 to 6, portions of small volume. It is strongly not recommended to use salt in gout, if there is no way to abandon it, its quantity should be reduced. The basis of the diet in gout is lean fish and meat, which are cooked in boiled or baked form, vegetables and fruits. It is obligatory to consume dairy products every day.
Weight loss in obese patients can reduce uric acid levels. However, diets that cause ketosis (such as starvation) should be avoided.
