Low Histamine Diet vs Lactose-Free Diet

If you're struggling with digestive issues, it's likely that you've tried to identify the root cause behind them. There are a variety of diets that you may have heard of, and two popular ones are the low histamine diet and the lactose-free diet. Below, we'll outline what each of these diets entails, as well as the differences between them, who should follow them, potential benefits and side effects, recipe ideas, and more.

What is a Low Histamine Diet?

A low histamine diet involves avoiding or reducing your intake of foods that contain high levels of histamine. Histamine is a molecule that's made naturally within the body and is also present in many foods. It's released by cells in response to an allergen, injury, or infection, and can cause itching, sneezing, and inflammation. In some people, histamine intolerance can contribute to digestive problems like nausea, bloating, and diarrhea. A low histamine diet generally includes eliminating high-histamine foods like aged cheese, fermented foods, and smoked meats, as well as foods that cause the release of histamine, like citrus fruits and alcohol.

There are several other foods that are commonly avoided on a low histamine diet, including shellfish, tomatoes, spinach, and chocolate. Additionally, some people may need to avoid foods that are high in histidine, an amino acid that can be converted to histamine in the body. These foods include nuts, seeds, and certain types of fish.

It's important to note that a low histamine diet is not a cure for histamine intolerance or related conditions. It's simply a way to manage symptoms and reduce the amount of histamine in the body. If you suspect that you have a histamine intolerance, it's important to speak with a healthcare professional to determine the underlying cause and develop an appropriate treatment plan.

What is a Lactose-Free Diet?

A lactose-free diet involves avoiding or reducing your intake of lactose, a type of sugar found in milk and other dairy products. People who are lactose intolerant lack the enzyme necessary to digest lactose, which can lead to bloating, gas, and diarrhea. Lactose-free alternatives to dairy products are widely available, and many people successfully follow a lactose-free diet to manage their digestive issues.

It is important to note that a lactose-free diet does not necessarily mean a dairy-free diet. Many dairy products, such as hard cheeses and butter, contain very little lactose and may be well-tolerated by those with lactose intolerance. However, it is important to read labels carefully and consult with a healthcare professional or registered dietitian to ensure that you are meeting your nutritional needs while following a lactose-free diet.

Differences between Low Histamine and Lactose-Free Diets

While low histamine and lactose-free diets may seem similar, the root cause of the digestive issue is different. A low histamine diet is designed to address histamine intolerance, while a lactose-free diet is aimed at managing lactose intolerance. Additionally, the foods that are avoided on each diet differ. A low histamine diet eliminates high-histamine foods, while a lactose-free diet eliminates dairy products.

It is important to note that individuals with histamine intolerance may also have lactose intolerance, but not all individuals with lactose intolerance have histamine intolerance. Therefore, it is important to properly diagnose the underlying issue before starting a specific diet. It is also recommended to work with a healthcare professional or registered dietitian to ensure that the diet is nutritionally balanced and meets individual needs.

Foods to Avoid on a Low Histamine Diet

When following a low histamine diet, it's important to avoid foods that are high in histamine, foods that release histamine, and foods that contain histamine-producing bacteria. Foods to avoid include aged cheese, fermented foods like sauerkraut and kombucha, smoked meats, shellfish, certain fruits including citrus, and alcohol.

In addition to the foods mentioned above, it's also important to avoid foods that are high in histamine-releasing compounds such as caffeine, chocolate, and certain spices like cinnamon and cloves. These foods can trigger the release of histamine in the body, leading to symptoms such as headaches, hives, and digestive issues.

It's also worth noting that some foods may not be high in histamine themselves, but can still trigger histamine release in the body due to their high levels of tyramine. These foods include avocados, bananas, and nuts such as peanuts and cashews. If you're following a low histamine diet, it's important to be aware of these potential triggers and avoid them as well.

Foods to Avoid on a Lactose-Free Diet

If you're following a lactose-free diet, you'll need to avoid dairy products like milk, cheese, butter, and yogurt. Many processed foods also contain lactose, such as bread, crackers, and some types of cereal.

It's important to note that lactose can also be found in some unexpected places, such as salad dressings, sauces, and even some medications. Always check the ingredient list before consuming any product to ensure it is lactose-free.

Fortunately, there are many lactose-free alternatives available, such as almond milk, soy cheese, and coconut yogurt. It's also possible to find lactase supplements, which can help those with lactose intolerance digest small amounts of lactose.

How to Implement a Low Histamine Diet

If you think a low histamine diet might be right for you, it's important to work with a qualified healthcare professional to develop a personalized plan. In general, though, a low histamine diet involves eliminating high-histamine foods and focusing on fresh, whole foods. Planning meals ahead of time and having alternative options on hand can be helpful, especially during the initial period of adjustment.

It's also important to be aware of hidden sources of histamine, such as fermented foods, aged cheeses, and processed meats. Reading food labels and avoiding foods that contain additives like vinegar, soy sauce, and artificial colors can also be helpful. Keeping a food diary and tracking symptoms can help identify trigger foods and make it easier to stick to the low histamine diet.

How to Implement a Lactose-Free Diet

When following a lactose-free diet, it's important to read food labels carefully. Look for lactose-free dairy products, such as lactose-free milk and cheese, or try non-dairy alternatives like almond or soy milk. Focus on eating whole, fresh foods like fruits, vegetables, and lean proteins. Just like with a low histamine diet, planning ahead and having alternative options on hand is key.

It's also important to be aware of hidden sources of lactose in processed foods. Lactose can be found in unexpected places like bread, cereal, and even some medications. Be sure to check the ingredients list for any lactose-containing ingredients, such as whey or casein.

If you're struggling to get enough calcium on a lactose-free diet, consider taking a calcium supplement or incorporating calcium-rich foods like leafy greens, tofu, and fortified non-dairy milks into your diet. It's important to maintain adequate calcium intake for bone health, especially if you're at risk for osteoporosis.

Benefits of a Low Histamine Diet

For people who suffer from histamine intolerance, following a low histamine diet can be life-changing. By reducing the amount of histamine in the body, symptoms ranging from skin irritation to gastrointestinal troubles can be improved. Additionally, because many high-histamine foods are also high in salt, sugar, and fat, following a low histamine diet can lead to an overall healthier lifestyle.

Benefits of a Lactose-Free Diet

Folks who are lactose intolerant can benefit from following a lactose-free diet by avoiding digestive symptoms like bloating, gas, and diarrhea. Additionally, a lactose-free diet may help alleviate other symptoms associated with lactose intolerance, such as headaches, joint pain, and itchy skin.

Side Effects of Consuming Histamines

In addition to digestive discomfort, consuming too much histamine can cause headaches, itching, flushing, and in severe cases, anaphylaxis. Left untreated, histamine intolerance can lead to the development of chronic conditions like migraines and autoimmune disorders.

Side Effects of Consuming Lactose

If you're lactose intolerant, consuming dairy products can lead to bloating, gas, and diarrhea. Over time, chronic exposure to lactose can lead to weakened bones due to decreased calcium absorption.

Who Should Follow a Low Histamine Diet?

Anyone experiencing histamine intolerance symptoms may benefit from a low histamine diet. Symptoms of histamine intolerance can include migraines, hives, congestion, and digestive issues. A healthcare professional can help determine the root cause of these symptoms, but if histamine intolerance is determined to be the issue, a low histamine diet may be suggested.

Who Should Follow a Lactose-Free Diet?

Individuals who suffer from lactose intolerance may benefit from a lactose-free diet. Symptoms of lactose intolerance are often digestive in nature, including bloating, gas, and diarrhea. If you are experiencing these symptoms, it's recommended that you speak with a healthcare professional to determine the cause.

Recipes for Low Histamine Meals and Snacks

Following a low histamine diet doesn't have to be boring or restrictive! Try making meals based around fresh, whole foods like grilled chicken with roasted vegetables or gluten-free pasta with pesto. Snack on fresh fruits like berries or sliced cucumbers with hummus. There are many resources available online that provide inspiration for low histamine meals and snacks.

Recipes for Lactose-Free Meals and Snacks

Just like with a low histamine diet, there are plenty of delicious and satisfying lactose-free options available. Try making a breakfast of oatmeal with almond milk and fresh fruit, or a lunch of grilled chicken with quinoa and vegetables. Snack on trail mix with nuts and dried fruit or rice cakes with nut butter. Again, the internet is a great resource for lactose-free recipe ideas.

Risks Associated with Low Histamine Diets

While a low histamine diet can be beneficial for those who suffer from histamine intolerance, it's important to note that eliminating certain foods from your diet can lead to potential nutrient deficiencies. Speak with a healthcare professional to ensure that any nutrient gaps are being addressed, and consider supplementing with vitamins and minerals as necessary.

Risks Associated with Lactose-Free Diets

If you're following a lactose-free diet, it's important to make sure that you're getting enough calcium to support bone health. Calcium can be found in non-dairy sources like leafy greens and nuts, but a calcium supplement may also be necessary. Additionally, if you're following a strict lactose-free diet, make sure that you're getting enough vitamin D, which helps the body absorb calcium.

Can You Combine Both Diets?

While it's possible to combine both diets, it may be necessary to seek guidance from a healthcare professional or registered dietitian to ensure that nutrient needs are being met. Foods that are high in histamine are often high in calcium and vitamin D, so if you're following a low histamine diet, you may need to be more deliberate in seeking out non-dairy calcium sources.

Final Thoughts: Which Diet is Right for You?

The answer to this question will depend on your individual needs. If you're experiencing digestive issues and suspect that you may be lactose intolerant, a lactose-free diet may be a good option. If you're experiencing migraines, hives, or other symptoms of histamine intolerance, a low histamine diet may be worth exploring. It's important to work with a qualified healthcare professional or registered dietitian when considering making significant changes to your diet.
