October 7, 2025 •

5 min read

While glutamate is a naturally occurring amino acid in many foods, a significant portion of the population is sensitive to high levels, particularly when consumed as a free-form additive like MSG. For those concerned with their intake, understanding what meat has the least glutamate? is a crucial first step in modifying protein consumption.

Quick Summary

This article examines which types of meat contain lower levels of glutamate, highlighting options like lamb and eggs, while also identifying meats and processed products with higher glutamate content for dietary management.

Key Points

Lowest options: Fresh lamb, eggs, and certain fish like cod and salmon are generally the lowest glutamate protein sources.
Highest options: Meats such as turkey, rabbit, and cured ham contain higher levels of glutamate and should be limited on a low-glutamate diet.
Cooking method matters: Slow cooking and simmering meats can increase the release of free glutamate, so fresh, quicker cooking methods are preferable.
Processed food caution: Cured and processed meat products, like sausages and lunch meats, are often high in glutamate due to added flavorings.
Check ingredients: Always read labels for hidden sources of glutamate and aspartate, such as yeast extract and hydrolyzed protein.
Focus on whole foods: A low-glutamate diet emphasizes fresh, unprocessed ingredients, not just limiting specific meat types.
Professional guidance: Consult a healthcare provider or dietitian before changing your diet, especially if you have a medical condition related to glutamate sensitivity.

Understanding Glutamate in Your Diet

Glutamate is a non-essential amino acid, meaning the body can produce it, but it is also naturally present in many foods. As the primary excitatory neurotransmitter in the brain, it plays a vital role in nervous system function. However, some individuals experience adverse reactions or health symptoms linked to glutamate sensitivity, and those with specific neurological conditions, such as epilepsy, may be advised to follow a low-glutamate diet.

Dietary glutamate comes in two main forms: bound and free. Bound glutamate is part of a larger protein molecule, which the body breaks down slowly during digestion. Free glutamate, on the other hand, is not bound and is readily available for absorption. The free form is what contributes to the savory 'umami' flavor and is often the primary concern for those with sensitivity. Foods that are fermented, cured, or aged contain higher levels of free glutamate.

Meats with Lower Glutamate Content

For those seeking to limit their glutamate intake, choosing the right types of meat and preparation methods is essential. The following meats and proteins are generally considered to be on the lower end of the glutamate spectrum.

Lamb: Often cited as one of the lowest glutamate meats, fresh lamb is an excellent choice for a low-glutamate diet.
Eggs: A great protein source that is naturally low in both glutamate and aspartate.
Chicken: Fresh, unprocessed chicken is fairly low in glutamate. However, it is important to choose plain chicken over processed chicken products.
Certain Fish: Fresh, wild-caught fish like cod and salmon are good options for a low-glutamate diet. Cured or tinned fish, or those like anchovies, should be avoided.

Other low-glutamate proteins and considerations

Beyond specific meat types, preparing protein in a way that minimizes free glutamate is important. For instance, fresh is better than preserved, and shorter cooking times can help. Eggs, being particularly low in glutamate, are a versatile protein source that can be used in numerous dishes. Choosing fresh, whole cuts of meat over processed versions is a key strategy for reducing intake.

Meats and Preparations Higher in Glutamate

Just as some meats are lower in glutamate, others are significantly higher. Certain cooking and processing methods can also increase the amount of free glutamate.

Turkey and Rabbit: These poultry and game meats are often identified as having higher glutamate levels than chicken or lamb.
Processed and Cured Meats: This category includes items like cured ham, bacon, sausages, and luncheon meats. Curing and processing often add free glutamate and other flavor enhancers to improve taste and preservation.
Slow-Cooked Meats: While delicious, slow-cooking meat in stews or broths can increase the concentration of free glutamates as the proteins break down. Similarly, bone broths are high in glutamate due to the long cooking time.
Aged Meats and Cheeses: The aging process enhances the umami flavor by creating more free glutamate. While not meat, high-glutamate dairy items like aged parmesan should be considered in a low-glutamate diet.

Comparison of Meats by Glutamate Content

To make informed choices, here is a quick reference table comparing some common protein sources and their typical free glutamate levels. Note that exact values can vary based on freshness, preparation, and cut.


Protein Source	Free Glutamate Content (mg/100g)	Considerations	Source
Cod (Fresh)	9	One of the lowest fish options.
Pork (Fresh Fillet)	10	Fresh pork is a moderate option.
Beef (Fresh)	10	Fresh beef is a moderate option.
Chicken (Fresh)	20-50	A relatively low-glutamate poultry choice.
Eggs	20-23	Excellent low-glutamate protein source.
Lamb (Fresh)	113-283	Generally considered a very low-glutamate meat.
Cured Ham	337	A very high-glutamate option due to processing.

Note: The glutamate data provided from umamiinfo.com and other sources varies slightly due to measurement techniques, but the relative rankings typically remain consistent.

Beyond Meat: A Broader Low-Glutamate Perspective

While the focus is on meat, a truly low-glutamate diet requires attention to a wider range of foods. Many of the most potent sources of glutamate are not meat products. High-glutamate foods to be aware of include aged cheeses (especially Parmesan), soy sauce, mushrooms, and ripe tomatoes. Additionally, many processed foods and flavor enhancers contain added glutamate or ingredients that release it, such as yeast extract and hydrolyzed vegetable protein. Cooking methods also play a role; slow-cooked bone broths, for example, are high in glutamate. Instead, opting for fresh ingredients, minimizing processed items, and choosing fast-cooked proteins is a more effective approach.

Making Healthy, Low-Glutamate Choices

For those sensitive to glutamate or following a specific diet, careful planning is key. Prioritize fresh, unprocessed whole foods, including a variety of fruits, vegetables, and whole grains. When selecting meat, favor naturally lower options like fresh lamb, eggs, and certain fish. Cooking at home is the best way to control ingredients and avoid hidden sources of glutamate in processed seasonings and flavorings. Reading ingredient labels is crucial, checking for terms like 'yeast extract,' 'hydrolyzed protein,' or 'flavoring' that may indicate added free glutamate. Always discuss dietary changes with a healthcare provider, especially if managing a health condition.
