Alkaline phosphatase is an essential enzyme with various functions in the body, ranging from aiding digestion to supporting bone health. Elevated levels of this enzyme can be a signal of underlying health issues that should not be ignored. This article provides a comprehensive guide on what foods to avoid if alkaline phosphatase is high, empowering you to manage this condition through informed dietary choices.

Understanding Alkaline Phosphatase

What is Alkaline Phosphatase?

Alkaline phosphatase is an enzyme found in several tissues throughout the body, including the liver, bones, and digestive system. It plays a vital role in breaking down proteins, aiding digestion, and assisting in bone development.

Roles in Digestion, Bone Health, and Liver Function

In the digestive system, alkaline phosphatase helps in the breakdown of fats and proteins. In the context of bone health, it is essential for bone mineralization. For liver function, it aids in bile production, crucial for fat digestion.

Normal vs. Elevated Levels

A standard range for alkaline phosphatase levels exists, usually determined through a blood test. Elevated levels may indicate a range of health concerns, from liver disease to bone disorders.

Causes of Elevated Alkaline Phosphatase

  • Liver Diseases: Conditions like cirrhosis or hepatitis can lead to elevated alkaline phosphatase levels.
  • Bone Disorders: Osteoporosis and Paget’s disease are examples of bone disorders that can cause elevated levels of this enzyme.
  • Gastrointestinal Issues: Certain gastrointestinal conditions like celiac disease can also result in high alkaline phosphatase levels.
  • Other Health Conditions: Other factors such as certain cancers, diabetes, and heart failure can also contribute to elevated levels.

The Role of Diet in Alkaline Phosphatase Levels

How Diet Can Contribute to Elevated Levels

Your diet plays a crucial role in managing your alkaline phosphatase levels. Foods high in fat and sugar, for instance, can exacerbate liver conditions, leading to increased levels of this enzyme.

Foods Commonly Linked to Elevated Alkaline Phosphatase

Foods rich in unhealthy fats, refined sugars, and excessive salt can contribute to liver and bone conditions that may raise your alkaline phosphatase levels.

What Foods to Avoid If Alkaline Phosphatase Is High

High-Fat Foods

  • Examples: Fast food, fatty cuts of meat, cream-based sauces
  • Impact: High-fat foods can stress the liver, leading to elevated alkaline phosphatase levels.

Processed Foods

  • Examples: Packaged snacks, canned soups, processed meats
  • Ingredients to Watch Out For: High fructose corn syrup, trans fats, artificial colors
  • Effect: These ingredients can negatively impact liver function and contribute to high alkaline phosphatase levels.

Sugary Beverages

  • Types: Soda, energy drinks, sugary iced teas
  • Effects: Excessive sugar intake can lead to fatty liver disease, affecting alkaline phosphatase levels.


  • Types: Beer, wine, hard liquor
  • Impact: Alcohol is a major stressor on the liver and can significantly elevate alkaline phosphatase levels.

Red Meat

  • Connection to Liver and Bone Health: High consumption of red meat can contribute to liver stress and may affect bone mineralization.

Dairy Products

  • Examples: Full-fat cheese, cream, butter
  • Lactose and Its Effects: Some people have difficulty digesting lactose, which can impact alkaline phosphatase levels.

Fried Foods

  • Examples: Fried chicken, french fries, onion rings
  • How They Contribute: The oils used in frying can be high in trans fats, which are detrimental to liver health.

Salted Snacks

  • Examples: Potato chips, pretzels, salted nuts
  • Sodium’s Role: High sodium intake can exacerbate liver conditions, leading to increased enzyme levels.

Certain Seafood

  • High in Heavy Metals: Fish like shark and swordfish can be high in mercury, which affects liver health.

White Bread and Pasta

  • Examples: Baguettes, spaghetti, white rice
  • Impact: Refined carbohydrates can lead to weight gain and liver stress, indirectly affecting alkaline phosphatase levels.

By steering clear of these foods, you can take a significant step towards managing elevated alkaline phosphatase levels. Each of these categories has been linked to liver or bone health issues that can result in elevated levels of this crucial enzyme. Your diet plays a vital role in your overall health, and making informed choices can help you maintain optimal alkaline phosphatase levels.

Refined Carbohydrates and Their Impact

Refined carbohydrates, found in foods like white bread, pasta, and sugary cereals, can have a detrimental impact on your alkaline phosphatase levels. These types of carbs are quickly converted into sugar in the body, leading to a spike in insulin levels. Elevated insulin levels can cause the liver to produce more fat, leading to conditions like fatty liver disease, which in turn can elevate alkaline phosphatase levels. Moreover, refined carbohydrates contribute to weight gain, another risk factor for liver disease.

Lifestyle Changes to Consider

  • Exercise and Its Impact: Regular exercise not only helps in weight management but also improves liver function. A consistent exercise routine can help lower alkaline phosphatase levels by improving liver health and enhancing bone mineralization.
  • Stress Management Techniques: Stress hormones can adversely affect the liver. Practices like mindfulness, meditation, and deep-breathing exercises can help manage stress and, consequently, may help regulate alkaline phosphatase levels.
  • Importance of Regular Medical Check-Ups: Routine health screenings can catch elevated alkaline phosphatase levels early. The sooner you know, the faster you can take action to manage it through diet and lifestyle changes.

When to Consult a Healthcare Provider

If you experience symptoms such as fatigue, unexplained weight loss, or jaundice, it’s crucial to consult a healthcare provider. These could be indicators of liver or bone disorders that require immediate attention. A healthcare provider can conduct necessary tests and provide expert advice tailored to your condition.


Managing elevated alkaline phosphatase levels is not just about avoiding certain foods; it’s a holistic approach that involves a balanced diet and lifestyle changes. Regular exercise and stress management techniques are equally important in regulating this enzyme. However, if you experience any symptoms related to elevated alkaline phosphatase, immediate consultation with a healthcare provider is crucial. By adopting these guidelines, you empower yourself to take control of your health, ensuring a balanced level of alkaline phosphatase and overall well-being.
