What Foods To Avoid If Alkaline Phosphatase Is High?

what foods to avoid if alkaline phosphatase is high

Alkaline phosphatase is an enzyme found in the different parts of your body like the liver, bones, and intestines. It plays a vital role in maintaining your overall health.

However, when the levels of alkaline phosphatase become elevated, it could be a sign of an underlying health issue. And sometimes you eat something that raises your ALP and you don’t realize it.

So in today’s blog post, we will explore the causes of high alkaline phosphatase and focus on the diet for managing your ALP. Specifically, we will discuss 7 foods that are best avoided if alkaline phosphatase levels are high, and provide insights into healthier alternatives.

Alkaline phosphatase (ALP) is a hydrolase enzyme found in numerous tissues throughout the body. It removes phosphates from various substances like proteins, nucleotides, and alkaloids.

The highest concentrations of ALP are present in the cells that comprise bone and the liver. But it also exits in other parts of the body like:

  • Your kidneys.
  • Your bile duct.
  • Your intestines.
  • The placenta in pregnant people.

Elevated levels of ALP in the blood can often indicate liver disease or bone disorders.

Interestingly, children and adolescents usually have higher levels of ALP than adults due to bone growth. Doctors can detect ALP levels through a simple blood test, often part of a routine liver panel.

In healthy adults, ALP levels typically range from 20 to 140 units per liter (U/L). If ALP levels are high, it may sign of medical conditions like liver disease, bone disorders, or certain types of cancer.

On the other hand, if your ALP levels are low it could indicate malnutrition or a lack of certain vitamins. So, it’s important to keep your ALP level balanced for good overall health.

Also, it’s important to note that certain medications, smoking, and even some foods can contribute to increased ALP levels. For this reason, following to a carefully planned diet can be a significant factor in managing ALP levels.

What causes high levels of alkaline phosphatase?

There are many factors that cause high levels of alkaline phosphatase. These include liver diseases like hepatitis, cirrhosis, gallstones, or liver cancer.

Bone disorders like Paget’s disease, osteomalacia, or hyperparathyroidism can also cause elevated ALP levels. Furthermore, certain cancers that have spread to the bones or liver can cause a rise in ALP.

In addition to these conditions, high levels of ALP can also be a result of a blockage in the bile ducts or an infection in the gallbladder [1]. Pregnant women may also experience increased ALP levels, especially in the third trimester, due to increased placental activity.

Certain medications, including birth control pills, some antibiotics, and certain painkillers, can also raise ALP levels. This is why it’s important to inform your healthcare provider about any medications you are currently taking.

Lastly, consuming excessive amounts of alcohol or fatty foods can cause higher ALP levels. We will shortly discuss what should you eat or avoid to fully maintain your ALP levels.

But before you move next it is important to understand the level at which Alkaline Phosphate becomes dangerous and causes complications. Here’s how you can check it.

It’s recommended to consume fresh, whole foods as much as possible. Fresh fruits and vegetables, lean meats, whole grains, and legumes are all excellent choices that can contribute to overall health and help regulate ALP levels.

4. Foods higher in phosphorus

Nowadays, many people are curious about which foods to avoid if their alkaline phosphatase is high. The answer lies in phosphorus. This amazing mineral makes up about 1% of our body weight and is crucial for the health of our cells and bones.

So, a high intake of phosphorus can lead to an increase in ALP activity. Foods high in phosphorus include:

  • Dairy products like milk, cheese, yogurt, and ice cream
  • Processed foods like frozen meals and fast food
  • Red meat and poultry
  • Fish, especially canned or processed
  • Nuts and seeds
  • Beans, lentils, and other legumes
  • Whole grains and bran cereals
  • Dark-colored sodas

Limiting your intake of these foods and opting for low-phosphorus alternatives can help manage your ALP levels.

5. High-Fructose Foods

Consuming too much fructose can raise the risk of liver disease, leading to higher levels of Alkaline Phosphatase.

Consuming large quantities of high-fructose foods and beverages can cause non-alcoholic fatty liver disease (NAFLD), a condition characterized by excess fat build-up in the liver.

A study has shown that a diet high in fructose can increase ALP levels, as it causes an increase in liver fat and inflammation. High-fructose foods to avoid include:

  • Soda and other sweetened beverages
  • Candy and sweets
  • Sweetened cereals
  • Processed foods
  • High-fructose fruits like apples, grapes, watermelons, pears, and mangoes

It is healthier to choose foods with naturally occurring sugars, like fresh fruits and vegetables, and to limit the intake of foods with added sweeteners.

6. Certain Herbal Supplements

Some herbal supplements may negatively affect the liver which causes rise in ALP levels. Supplements like kava, comfrey, green tea extract, and pennyroyal oil have all been linked to liver damage in some cases.

For instance, a study has shown that the use of the herbal supplement kava can cause hepatotoxicity, which is evident through elevated levels of liver enzymes including ALP. Be cautious with the following supplements:

  • Kava
  • Comfrey
  • Green tea extract
  • Pennyroyal oil

Do not take any supplements without the recommendation of your doctor, especially if you have elevated ALP levels or other liver-related health issues. Always choose high-quality, reputable supplement brands to ensure safety and efficacy.

7. Foods that are high in Vitamin B-12

Vitamin B-12 which is also called cobalamin. It is important for making DNA, red blood cells, and keeping the nervous system working well.

However, an excess intake may cause complications like imbalances in homocysteine levels, which are related to heart disease and stroke. Certain foods are notably high in Vitamin B-12, and these include:

  • Fish like salmon and tuna
  • Shellfish such as clams and oysters
  • Beef and beef liver
  • Eggs
  • Dairy products like milk, cheese, and yogurt
  • Fortified breakfast cereals

These products and food items can increase the production of ALP which may cause problems with bone marrow.

So, it’s wise to limit the intake of these Vitamin B-12 rich foods. If you’re worried about your Vitamin B-12 levels, seek guidance from your doctor or a dietitian for personalized advice.

The American Heart Association recommends at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous exercise per week.

What level of alkaline phosphatase is concerning?

The levels of Alkaline Phosphatase (ALP) can vary greatly depending on age, gender and individual health conditions.

According to NIH, the normal level of ALP in human blood is usually between 25 and 100 IU/L. However, when the ALP concentration goes beyond 300 IU/L it may be a cause for concern.

This high level of ALP causes different diseases like liver diseases, liver cancer, bone disease, hepatitis, kidney cancer, and osteoblastic bone cancer.

In contrast, low ALP levels can also be problematic. If your Alkaline Phosphatase levels consistently drop below 20 U/L, it is considered dangerously low.

Having consistently low levels can cause serious health problems, like certain types of anemia, not getting enough protein, or overall malnutrition which can all negatively impact your health.

Why is it important to control high alkaline phosphatase levels?

Keeping your Alkaline Phosphatase (ALP) levels in check is important for maintaining a healthy body and overall well-being. When ALP levels are too high, it could be a sign of serious health issues like liver disease, blocked bile ducts, or certain bone disorders.

High levels of ALP can cause increased bone density or overly active bone formation. In the context of liver diseases, High ALP levels might imply damage or stress to the liver cells, potentially causing cirrhosis or hepatitis.

Additionally, studies have shown that elevated ALP levels are linked with increased mortality rates in people with cardiovascular conditions. Hence, it is highly recommended to regularly monitor and manage ALP levels as part of a complete healthcare strategy.

Keeping a balanced diet, regular exercise and routine health check-ups are effective ways to maintain healthy ALP levels.


In conclusion, maintaining balanced Alkaline Phosphatase (ALP) levels is a basis of overall health and well-being. Through a combination of a nutrient-dense diet, regular physical activity, stress management, and routine health check-ups, individuals can effectively manage their ALP levels.

It’s essential to remember that prolonged high or low ALP levels can be indicative of serious health issues.By taking quick actions, people can reduce potential health risks, which not only benefits their liver and bones but also their overall well-being.
