Here are foods and dietary considerations to avoid or limit:

1. Grapefruit and Grapefruit Juice

Why to Avoid: Grapefruit can interfere with the enzymes that metabolize anastrozole, potentially increasing its concentration in your blood. This can lead to a higher risk of side effects.

Recommendation: Avoid eating grapefruit or drinking grapefruit juice while taking anastrozole.

2. Processed and High-Sugar Foods

Why to Avoid: Anastrozole can cause weight gain and increase the risk of developing insulin resistance. High-sugar and processed foods can contribute to weight gain, negatively impacting overall health.

Recommendation: Reduce your intake of sugary snacks, sodas, and processed foods like pastries, candies, and fast food.

3. Alcohol

Why to Avoid: Alcohol can increase the risk of bone loss, which is already a concern with anastrozole. Excessive drinking can also worsen liver function and exacerbate certain side effects like dizziness or nausea.

Recommendation: Limit or avoid alcohol while on anastrozole to support bone health and minimize side effects.

4. High-Fat Foods

Why to Avoid: Anastrozole may raise cholesterol levels, which is a risk factor for heart disease. Consuming large amounts of saturated and trans fats can worsen cholesterol levels and heart health.

Recommendation: Avoid or limit fatty meats, fried foods, butter, and other sources of unhealthy fats. Focus on healthy fats like those found in avocados, olive oil, and nuts.

5. Salty Foods

Why to Avoid: Excessive salt intake can raise blood pressure and cause fluid retention, which can be uncomfortable for those taking anastrozole. It may also contribute to bone loss over time.

Recommendation: Reduce consumption of high-sodium foods such as processed meats, canned soups, and salty snacks.

6. Soy Products (in Excess)

Why to Avoid: Soy contains phytoestrogens, plant-based compounds that mimic estrogen in the body. Since anastrozole works by lowering estrogen levels, excessive soy intake may interfere with the medication’s effectiveness.

Recommendation: Limit consumption of soy-rich foods like tofu, soy milk, and soy protein powders.

7. Caffeine

Why to Avoid: Some people taking anastrozole experience joint pain or bone discomfort, and excessive caffeine can exacerbate this issue by contributing to calcium loss and bone weakening.

Recommendation: Limit caffeine intake from coffee, energy drinks, and sodas to support bone health.

8. High-Oxalate Foods

Why to Avoid: Foods high in oxalates, such as spinach, beets, and rhubarb, can inhibit calcium absorption. Since anastrozole may contribute to bone thinning, it’s essential to ensure optimal calcium absorption for bone health.

Recommendation: Balance your intake of high-oxalate foods with calcium-rich options like dairy or fortified non-dairy alternatives.

Why to Avoid: High intake of red and processed meats can raise cholesterol levels and contribute to inflammation, which may worsen joint pain — a common side effect of anastrozole.

Recommendation: Choose lean proteins like chicken, turkey, fish, and plant-based sources instead of red or processed meats.

Why to Avoid: Anastrozole can cause hot flashes. Spicy foods, caffeine, and alcohol may worsen this side effect.

Recommendation: Avoid hot-flash triggers like spicy dishes, caffeinated beverages, and alcohol.
