The packaging of every medication lists its contraindications. Drugs are involved in the entire digestive process and can interact with the cigarette you smoke, the juice you drink, or the food you eat. Therefore, it is necessary to know the dietary restrictions for the medications you are taking to prevent reduced efficacy and even adverse reactions. Below, we introduce 14 common foods that can turn medication into poison.
☆Any medication — Cigarettes
Do not smoke within 30 minutes of taking any medication. Nicotine accelerates the liver's breakdown of the drug, leading to insufficient drug concentration in the blood and making it difficult to achieve its full effect. Experiments have shown that smoking within 30 minutes of taking medication can reduce the blood drug concentration to about 1/20 of that in non-smokers.
☆Aspirin — Alcohol, Juice
After entering the human body, alcohol needs to be oxidized into acetaldehyde and then further oxidized into acetic acid. Aspirin interferes with the oxidation of acetaldehyde to acetic acid, causing acetaldehyde to accumulate in the body. This not only aggravates symptoms like fever and body aches but can also easily cause liver damage. Meanwhile, juice can exacerbate the irritation of aspirin on the gastric mucosa, inducing gastric bleeding.
☆Berberine — Tea
Tea water contains about 10% tannins. Tannins break down into tannic acid in the human body, which precipitates the alkaloids in berberine, significantly reducing its efficacy. Therefore, you should not drink tea within 2 hours before or after taking berberine.
☆Ibuprofen — Coffee, Cola
Ibuprofen (e.g., Fenbid) is highly irritating to the gastric mucosa. The caffeine in coffee and the cocaine in cola both stimulate gastric acid secretion, thus exacerbating the toxic side effects of ibuprofen on the gastric mucosa and even inducing gastric bleeding or perforation.
☆Antibiotics — Milk, Juice
Do not drink milk or juice within 2 hours before or after taking antibiotics. Milk can reduce the activity of antibiotics, preventing them from being fully effective. The fruit acids in juice (especially fresh juice) accelerate the dissolution of antibiotics, not only reducing their efficacy but possibly generating harmful by-products and increasing toxic side effects.
☆Calcium supplements — Spinach
Spinach contains a large amount of potassium oxalate. After entering the human body, the oxalate ions released will precipitate calcium ions, not only hindering the body's absorption of calcium but also easily forming calcium oxalate stones. Experts suggest not eating spinach within 2 hours before or after taking calcium supplements, or blanching the spinach first to dissolve the potassium oxalate into water, then discarding the water before consumption.
☆Antihistamines — Cheese, Meat products
While taking antihistamines, avoid foods rich in histamine, such as cheese and meat products. Histamine is converted into histamine in the body, and antihistamines inhibit the breakdown of histamine, leading to its accumulation and inducing symptoms like dizziness, headache, and palpitations.
☆Bitter stomachics — Sweet foods
Bitter stomachics rely on their bitter taste to stimulate the secretion of digestive fluids like saliva and gastric juice to promote appetite and aid digestion. Sweet components not only mask the bitterness and reduce efficacy but also form chelation reactions with many ingredients in the stomachic, reducing the content of its active ingredients.
☆Diuretics — Bananas, Oranges
While taking diuretics, potassium tends to be retained in the blood. Eating potassium-rich bananas or oranges at the same time can lead to a more severe accumulation of potassium in the body, easily triggering complications related to the heart and blood pressure.
☆Vitamin C — Shrimp
Do not eat shrimp within 2 hours before or after taking Vitamin C. The abundant copper in shrimp oxidizes Vitamin C, rendering it ineffective. Additionally, the pentavalent arsenic in shrimp can react with Vitamin C to form toxic trivalent arsenic.
☆Tonic Chinese medicine — Radish
Tonic Chinese medicine works by replenishing Qi, thereby nourishing the body's Qi, blood, Yin, and Yang. Radish has the effect of breaking Qi, which can significantly weaken the tonic effect. Therefore, radish should be avoided while taking tonic Chinese medicine.
