Alkaline phosphatase (ALP) is an enzyme found in many tissues — especially the liver, bones, and digestive system. It plays an important role in bone growth and liver function. A normal ALP range for adults is usually 30–130 IU/L, though it can vary depending on age, gender, and even race.
When ALP levels are higher than normal, it may signal problems with the liver, gallbladder, bones, or even the kidneys. That’s why paying attention to your diet is important — because certain foods can worsen the problem, while others may help bring your enzyme levels back into balance.
Let’s take a look at foods you should avoid if your ALP is high, and what you can safely include instead.
Foods to Avoid
1. Zinc-Rich Foods
Zinc supports healthy bones, but too much of it can raise ALP further. If your test results already show elevated levels, it’s best to cut back on foods like:
Oysters and crabs
Beef, pork, and dark meat chicken
Cashews and baked beans
Yogurt
2. Oils and Fats
Some oils can stimulate more ALP activity, especially if consumed regularly.
Cod liver oil
Coconut oil
Corn oil
Instead, use small amounts of healthier fats like olive oil in moderation.
3. Phosphorus-Rich Foods
Phosphorus is essential for bone health, but too much of it can add to the problem when ALP is already high. Limit:
Dairy (milk, cheese, yogurt)
Eggs
Red meat and poultry
Fish like salmon
Whole wheat bread, nuts, and lentils
Cola and other fizzy drinks
4. Vitamin B12-Rich Foods
Vitamin B12 supports blood and nerve function, but in high ALP conditions, certain foods may increase enzyme activity. Limit or avoid:
Clams and mussels
Crab
Brie cheese
Eggs
Foods to Include
If you need to support healthy ALP levels, focus on foods that are easier on your liver and bones while still providing good nutrition:
Fresh fruits and vegetables (antioxidant-rich and anti-inflammatory)
Whole grains in moderation
Lean proteins like fish (herring, tuna), but only if your doctor allows
Mushrooms (a plant-based option with useful nutrients)
Plenty of water to stay hydrated and support detoxification
Why It Matters
Uncontrolled high ALP can be linked to liver damage, gallstones, bone disorders, or even certain cancers. On the other hand, very low levels may indicate malnutrition, zinc deficiency, or rare conditions like hypophosphatasia.
Keeping your diet balanced — and working with your doctor or dietitian — is the best way to manage ALP levels naturally, along with any medical treatment needed.
Final Thoughts
Diet alone won’t “cure” high alkaline phosphatase, but it can make a big difference in how well your body manages enzyme activity. By avoiding zinc, phosphorus, B12-heavy foods, and certain oils, while adding more fresh produce and lighter proteins, you can support your liver and bone health more effectively.
If your blood tests show high ALP, don’t ignore it. Adjust your diet, stay active, and consult a healthcare professional for personalised guidance.
