If you’ve recently had bloodwork done and noticed your alkaline phosphatase (ALP) levels are high, you’re probably wondering what that means—and, in particular, what foods to avoid if alkaline phosphatase is high, or maybe which ones to eat to combat it. 

This article will guide you through understanding ALP, pinpoint potential causes for elevation, and provide a clear list of foods to avoid. You’ll also learn how to make dietary changes to support healthier ALP levels and overall well-being.

Key Article Findings

  • High ALP levels can result from various factors, so dietary adjustments should be part of a broader health management plan.
  • Your liver and bones are two key areas affected by ALP, and certain foods can either support or stress these functions.
  • A balanced, nutrient-rich diet is essential for overall well-being, but some foods may contribute to elevated ALP levels and should be limited.

What is Alkaline Phosphatase (ALP)?

Alkaline phosphatase (or alk phos) is an enzyme present in different tissues, with the highest concentrations in the liver and bones. It plays a crucial role in various bodily processes, including metabolism and bone formation.

The normal ALP range varies by age and sex, but for most adults, levels typically fall between 44 and 147 international units per liter (IU/L). Doctors often check ALP levels through routine blood tests to monitor overall health.

Why is High ALP a Concern?

Elevated ALP levels may indicate changes in liver or bone function, so it’s important to pinpoint the underlying cause. While symptoms of high ALP can vary, some people experience fatigue, weakness, or other subtle health changes. If your levels are elevated, making smart dietary choices could help support your body’s natural balance.

Causes and Symptoms of High Alkaline Phosphatase

Many people with high alkaline phosphatase (ALP) don’t notice symptoms right away. However, when symptoms do appear, they often relate to the underlying cause. Here’re possible symptoms of high ALP:

  • Unusual fatigue
  • Discomfort in the upper abdomen
  • Bone pain or tenderness
  • Unexplained weight changes

Several factors can lead to elevated ALP levels, typically linked to liver or bone health. Here’re potential causes of high ALP:

  • Liver-related issues – Changes in liver function or bile flow may increase ALP levels. Diet, lifestyle, and environmental factors can all play a role. Natural ingredients like milk thistle and turmeric root have traditionally been used to support liver health.
  • Bone-related changes – ALP plays a key role in bone metabolism, so aging, mineral imbalances, or certain bone conditions may contribute to higher levels.
  • Pregnancy – ALP naturally rises during pregnancy due to increased enzyme production by the placenta.
  • Other factors – Certain supplements, medications, or lifestyle habits may influence ALP readings.

For those looking to lower ALP levels, identifying the specific cause with a healthcare provider is the best first step.

What Foods to Avoid with High Alkaline Phosphatase?

Making informed dietary choices supports overall health when managing ALP levels. Here are specific foods to consider limiting:

1. Alcohol

Alcoholic beverages place additional stress on the digestive system and can interfere with the body’s natural enzyme balance. When ALP levels are high, alcohol consumption may compound existing challenges by making the liver work harder to process toxins. Even moderate amounts of alcohol can impact how well the body maintains proper enzyme levels.

2. Sugary Drinks and Foods

Sodas, candy, and packaged sweets containing refined sugars may create metabolic stress in the body. These items include:

  • Soft drinks and energy drinks
  • Packaged cookies and cakes
  • Candy bars and chocolate
  • Sweetened breakfast cereals

The high sugar content in these foods can affect how well the body processes enzymes and maintains proper ALP levels. Natural alternatives like fresh fruits provide sweetness while supporting overall health.

3. High-Fat Foods

Assortment of fried and processed high-fat foods.

Foods high in saturated fats can place additional strain on the digestive system when ALP levels are elevated. Problematic items include:

  • Processed meats (bacon, sausages, hot dogs)
  • Full-fat dairy products (whole milk, cream, butter)
  • Deep-fried foods (french fries, fried chicken)
  • Pastries and baked goods with high fat content

These foods require more digestive enzymes to break down, which can impact the body’s enzyme balance. They may also contribute to inflammation, making it harder for the body to maintain proper ALP levels.

4. Zinc-Rich Foods

While zinc is an essential mineral, it plays a direct role in ALP production. When ALP levels are already high, consuming too many zinc-rich foods may further affect enzyme balance. Foods particularly high in zinc include:

  • Oysters and shellfish
  • Red meat, especially organ meats
  • Pumpkin and sesame seeds
  • Aged cheeses and full-fat dairy

Moderation of these foods helps maintain appropriate enzyme levels while still ensuring adequate nutrition.

5. Processed Foods

Packaged and convenience foods often contain artificial additives, preservatives, and hidden fats that can impact enzyme function:

  • Pre-made frozen meals
  • Packaged snack foods (chips, crackers)
  • Fast food items
  • Processed deli meats

These foods often lack the natural compounds found in whole foods that support proper enzyme balance. Their high sodium content and artificial ingredients can also affect how well the body maintains proper ALP levels.

6. High-Oxalate Foods

Foods high in oxalates can affect mineral absorption and impact bone health, which is particularly important when ALP levels are elevated. These include:

  • Spinach and Swiss chard
  • Almonds and cashews
  • Wheat bran and quinoa
  • Black tea and green tea

Oxalates can bind to minerals in the digestive tract, potentially affecting how well the body maintains proper enzyme balance. When consumed in large amounts, these foods may influence calcium absorption, which is particularly relevant since ALP plays a role in bone health.

Foods to Enjoy with High Alkaline Phosphatase

A well-planned diet focusing on natural, minimally processed foods can support your body’s enzyme balance and overall health. The right food choices provide essential nutrients that help maintain proper function of various body systems.

Certain foods contain natural compounds that support enzyme balance and provide antioxidants that protect cells. These foods work together to create an environment where your body can better regulate its processes.
