Hypercalcemia, a condition defined by high blood calcium levels, affects millions and can weaken bones and create kidney stones. A key part of managing this condition is knowing what foods should I avoid if calcium is high?, which includes limiting high-calcium foods, certain fortified products, and excess vitamin D intake.

Quick Summary

Managing high blood calcium (hypercalcemia) often requires dietary changes. This guide explains which foods and supplements to limit or avoid, such as dairy products, calcium-fortified items, and certain canned fish, to help regulate your calcium levels and reduce associated health risks.

Key Points

Avoid Dairy Products: Limit or eliminate milk, cheese, yogurt, and ice cream, as they are a major source of dietary calcium.
Beware of Fortified Foods: Steer clear of products like juices, cereals, and milk substitutes that have calcium added to them.
Limit Certain Fish and Supplements: Avoid canned fish with bones (sardines, salmon) and stop taking calcium and vitamin D supplements unless directed by a doctor.
Watch Phosphates and Sodium: Reduce intake of carbonated drinks, processed foods, and high-sodium items, which can interfere with calcium balance.
Consider Oxalates: If you have a history of kidney stones, discuss limiting high-oxalate foods like spinach and rhubarb with your doctor.
Focus on Low-Calcium Alternatives: Choose low-calcium fruits, vegetables, lean meats, and unfortified grains to maintain a balanced diet.
Stay Hydrated and Active: Increase your fluid intake and engage in moderate exercise as recommended by your doctor to help manage calcium levels.
Consult Healthcare Professionals: Always work with your doctor and a registered dietitian to create a personalized plan for managing hypercalcemia safely and effectively.

Understanding Hypercalcemia and the Role of Diet

Hypercalcemia, or high blood calcium, is a condition that requires careful management, often including dietary modifications. While calcium is vital for bone health and nerve function, an excess can lead to complications such as kidney stones, bone pain, and heart problems. The most common cause is overactive parathyroid glands, but other factors like excessive vitamin D or calcium supplements, certain cancers, and medications can also be responsible. A low-calcium diet, along with avoiding specific foods, is a primary strategy for controlling calcium levels in the blood.

It's important to work closely with a healthcare provider to determine the underlying cause of your hypercalcemia before making any major dietary changes. The recommendations below are a general guide and should be discussed with a medical professional or a registered dietitian.

Foods and Supplements to Strictly Avoid or Limit

Dairy Products

For many, dairy is the primary source of dietary calcium. If your calcium levels are high, your doctor may advise you to cut back on or completely eliminate dairy products, especially those not fat-free or labeled with added calcium.

Milk: A glass of milk, especially fortified versions, is packed with calcium.
Cheeses: Hard cheeses, soft cheeses, and all other forms of cheese are high in calcium.
Yogurt and Ice Cream: These items are also high in calcium and should be avoided.
Pudding: Many ready-made and instant pudding mixes contain high levels of calcium.

Calcium-Fortified and Enhanced Foods

Many foods are fortified with calcium to help people reach their daily intake goals. However, for those with hypercalcemia, these products can push calcium levels higher and should be avoided.

Fortified Juices: Orange juice is a common example of a fortified product.
Fortified Milk Substitutes: Soy milk, almond milk, and other plant-based milks are often enriched with calcium.
Fortified Cereals and Breads: Check nutritional labels, as many brands add extra calcium.

Certain Canned Fish

Fish canned with soft, edible bones, such as sardines and salmon, contain a high concentration of calcium from the bones themselves and should be avoided.

Calcium-Containing Antacids

Some over-the-counter antacid medications use calcium carbonate as an active ingredient. If you rely on these for indigestion, check the label and switch to a calcium-free alternative as recommended by your doctor.

Excess Vitamin D and Calcium Supplements

Since vitamin D helps the body absorb calcium, excessive intake of vitamin D supplements can lead to high calcium levels. You should stop taking both calcium and vitamin D supplements unless a healthcare provider specifically instructs you otherwise.

Other Dietary Considerations to Manage Calcium Levels

Dietary management for hypercalcemia extends beyond simply cutting calcium-rich foods. Other nutrients and lifestyle factors play a role.

High-Phosphate Foods

While phosphorus is essential, high levels can also disrupt calcium balance. Many processed foods contain high levels of phosphorus-based additives. Limiting these is advisable. This includes:

Carbonated beverages: Colas and many sodas contain phosphoric acid.
Processed meats and deli meats: Many of these have phosphate additives.
Hard cheeses: As mentioned before, they are also high in phosphorus.

High-Oxalate Foods

Some vegetables, like spinach and rhubarb, contain high levels of oxalates, which can bind to calcium and potentially form kidney stones. While these foods don't directly raise blood calcium, limiting them can be a secondary measure, especially if you have a history of kidney stones. Always check with your doctor for specific advice regarding your oxalate intake.

Excessive Sodium

High sodium intake can lead to increased calcium excretion in the urine, a process that can pull calcium from your bones. Watching your sodium intake by reducing processed and salty foods can be beneficial.
