The lymphatic system is a vital component of both the circulatory and immune systems, playing a crucial role in regulating fluid balance and ensuring optimal immune function. However, like other systems in the body, the role of diet cannot be overlooked in the lymphatic system. Knowing the best and worst foods for lymphatic system function is essential in achieving good immune, circulatory, and overall body health.
What Is the Relationship Between Diet and the Lymphatic System?
A strong relationship exists between diet and the lymphatic system, comprising multiple facets. Firstly, the lymphatic system is an integral part of the immune system, playing a crucial role in combating foreign invaders. Likewise, diet is also an essential component of the immune system.
The immune cells need nutrients from your diet to function optimally.[1] Since the lymphatic system produces and transports immune cells (lymphocytes), it relies directly on your diet for its normal functioning. Unsurprisingly, an unhealthy diet can cause infections and cancer, which can lead to lymphatic system disorders.
What’s more, some foods promote high inflammation in the body. Inflammation is not inherently harmful and is, in fact, a core mechanism behind immune responses. However, unregulated and chronic inflammation can affect various body structures, including the lymphatic system.
In a similar but opposite way, certain foods can help reduce inflammation in the body and improve lymphatic and immune function. Knowledge of the role diet plays in inflammation is the basis behind this list of the best and worst foods for the lymphatic system.
The 10 Worst Foods for Lymphatic System
The worst foods for lymphatic system function are foods that cause inflammation, reduce resistance to infections, and increase the risk of cancer. Below are 10 of the worst foods for lymphatic system function.
1) Processed Meats
Processed meats are meats that have undergone processes to enhance their flavor or extend their shelf life, such as salting, curing, fermentation, smoking, or the addition of chemicals. While people generally associate processed meats with red meats, any meat can be processed.
Studies find that processed meat can raise inflammation and increase the risk of cancer, type 2 diabetes, cardiovascular disorders, and other chronic conditions.[2] All of these factors can directly contribute to lymphatic problems and a weakened immune system.
Examples of processed meats are:
- Bacon
- Ham
- Sausages
- Hot dogs
- Salami
- Pate
- Canned beef
- Bologna
- Lunch meat
2) Refined Grains
Refined grains are whole grains that have been stripped of their bran and germ, leaving only their endosperm, which makes them some of the worst foods for lymphatic function. The refining process increases the shelf life of the grains but also removes important nutrients, such as fiber, vitamins, minerals, and healthy fats, that can help combat inflammation.
Here are some examples of foods that contain refined grains:
- White flour
- White rice
- Corn grits
- White bread
- Bagels
- Crackers
- Cakes
3) Red Meat
Red meats generally refer to the meat of mammals, such as beef, pork, lamb, and goat. These meats have more of the protein myoglobin than white meats (such as chicken, turkey, and goose).
Research confirms that red meat can increase inflammatory biomarkers, which can affect the lymphatic system and overall immune function.[3] Red meat consumption also significantly increases the risk of heart disorders, cancers, type 2 diabetes, and overall mortality.
4) Ultra Processed Foods
Ultra-processed foods are those made with ingredients that are rarely or never used in household kitchens, typically containing additives whose sole purpose is to enhance palatability.[4] These foods typically have gone through multiple industrial processes to ensure the final product is hyper-palatable and has a significantly longer shelf life.
There is an adverse relationship between ultra-processed foods and lymph drainage. These foods also contain very few nutrients and are high in inflammatory and carcinogenic substances.
Examples include:
- Candies
- Sweets
- Chocolates
- Ice cream
- Soda
- Cookies
- Cakes
5) Added Sugars
Added sugars are sugars or sweeteners added to foods during processing or preparation. They are not naturally occurring in foods, and they can affect the lymphatic system.
Sugars themselves are not harmful, and the body’s cells require them for energy to survive and function properly.
But when there is excess blood sugar, the body releases insulin to facilitate the uptake of glucose into the cells or store glucose as glycogen. However, having elevated insulin levels for extended periods can cause oxidative stress (an imbalance of free radicals in the body). Oxidative stress can then lead to high levels of inflammation, which can negatively impact the lymphatic system.
Examples of foods with added sugars include:
- Baked goods
- Ice cream
- Candies
- Breakfast cereals
- Sweetened beverages, including juices, soft drinks, and energy drinks
- Sweetened yogurts
6) Fried Foods
Fried foods are often high in saturated fats, which can lead to high cholesterol levels. This cholesterol may solidify (in addition to other fatty substances) and limit normal blood flow, in a condition called atherosclerosis. The lymphatic system is also part of the circulatory system, meaning conditions of the heart can also affect lymphatic function.
Aside from their role in affecting blood circulation, fried foods also increase the risk of obesity as they are high in calories. Obesity causes different metabolic problems and is a risk factor for circulatory problems.
7) Trans Fats
Foods high in trans fats are some of the worst foods for lymphatic system function because of the high risks of heart problems. Trans fats form when liquid oils are solidified into fats. While they may occur naturally, trans fats are often made industrially through the partial hydrogenation of oils.
Trans fats increase the risk of several cardiovascular conditions, which may affect lymphatic function. Additionally, trans fats increase the risk of obesity and diabetes, both of which can affect the lymphatic system.
Examples of trans fats include:
- Fried foods
- Margarine
- Vegetable shortening
- Refrigerated dough products, such as cinnamon rolls
- Baked goods, such as pies and cakes
8) High-Salt Foods
High-salt foods are high in sodium, which can lead to water retention and an increase in blood volume, as sodium attracts water. The heart then has to work harder to circulate this blood, causing high blood pressure (HBP). High blood pressure can affect the contractile ability of the lymphatic vessels, affecting lymphatic circulation.
Interestingly, the effects are worse on afferent lymphatic vessels compared to efferent vessels.[5] Afferent vessels carry unfiltered lymph from body tissues to lymph nodes for filtration. Efferent vessels then carry filtered lymph out of the lymph nodes to other nodes or back into the bloodstream. Impaired afferent lymphatic circulation in HBP implies that waste products may accumulate in tissues instead of being filtered.
This ultimately means that lymphatic system toxins may increase. This may then place excess stress on the other detoxification structures (like the liver) that make up the Detoxification circuit of the NeuroEndoMetabolic (NEM) System. The NEM consists of six circuits, comprising different organs and systems, that help manage stress in the body.
However, problems with these organs and systems can cause the circuit to dysregulate. In this case, the Detoxification circuit may dysregulate due to altered lymphatic circulation. If this dysregulation persists, Adrenal Fatigue may develop. Adrenal Fatigue is a condition where the body cannot keep up with daily life stressors, leading to chronic fatigue, weight gain, hormonal imbalance, and other symptoms.
Therefore, high-salt foods are among the foods to avoid for detox and are also some of the worst foods for lymphatic system function. The maximum salt intake for adults is 6 grams (approximately one teaspoon) a day.
9) Caffeine
Caffeine is often a source of controversy among researchers when considering its impact on inflammation levels in regular quantities. Some believe it is anti-inflammatory, while others find that it can promote inflammation.
However, what is under no dispute is the harmful effects of caffeine in excessive amounts. Caffeine can cause heart problems, particularly related to heart rhythm, which may impact circulation. Other symptoms, such as headaches, insomnia, and digestive disturbances, may also follow.
The recommended maximum daily intake of caffeine is 400 milligrams, which translates to around two to three 12-fluid-ounce cups of coffee. Below is a list of common caffeine sources:
- Coffee
- Tea (including black, green, white, and oolong)
- Energy drinks
- Soda
- Chocolates (and other cocoa-containing products)
10) Dairy Products
The relationship between the lymphatic system and dairy products is a complex one. Some dairy products (like yogurt and eggs) have beneficial functions for the lymphatic system.
However, dairy products that are high in saturated fats can lead to cardiovascular problems, which can affect normal lymphatic circulation. These fats can also increase the risk of metabolic disorders, such as obesity and high blood sugar levels, which are potential contributors to inflammation.
It is particularly important to avoid dairy products if you find your body has a sensitivity to them, such as lactose intolerance.
The 8 Best Foods for the Lymphatic System
The beneficial foods for the lymphatic system are those that can reduce inflammation levels in the body, improve immune function, and maintain overall health.
However, while these foods have benefits, different people have different dietary and health needs. Therefore, ensure you consult your healthcare provider before making significant alterations to your diet.
Here are the best foods for the lymphatic system.
1) Fruits
Fruits can improve lymphatic function in different ways. For starters, many fruits contain antioxidants that directly help combat inflammation by neutralizing free radicals and reducing oxidative stress. Fruits that fall into this category usually contain polyphenols.
Additionally, fruits are also excellent sources of fiber. Increasing fiber intake is one of the essential dietary steps in improving lymphatic function, as fiber has anti-inflammatory properties and can limit overeating and excess weight gain.
Some of the best fruits to eat for the lymphatic system include:
- Berries (strawberries, cranberries, raspberries, blueberries, blackberries)
- Grapes
- Citrus fruits (oranges, lemons, grapefruits)
- Apples
- Pomegranates
- Avocados
- Olives
2) Green Leafy Vegetables
Leafy greens are rich in antioxidants and can help reduce inflammation levels in the body, thereby improving lymphatic function. Examples include:
- Kale
- Spinach
- Arugula
- Collard greens
- Beet greens
- Swiss chard
- Watercress
- Bok choy
- Romaine lettuce
- Turnip greens
3) Prebiotics and Probiotics
Prebiotics are dietary fiber that serve as food for normal bacteria living in the gastrointestinal tract (gut microbiota). On the other hand, probiotics are living microorganisms that have beneficial effects when taken in adequate amounts.
Probiotics can directly modulate the gut microbiota and produce anti-inflammatory substances, such as short-chain fatty acids (SCFAs). Prebiotics are fiber-based products that, aside from providing a healthy medium for gut microbiota to thrive, can also help regulate metabolic health.
Examples of probiotics are:
- Yogurt
- Miso
- Tempeh
- Kefir
- Kimchi
- Sauerkraut
Examples of prebiotics are:
- Chicory roots
- Onions
- Dandelion greens
- Asparagus
- Leeks
- Bananas
- Jerusalem artichokes
- Whole grains (oats, barley, brown rice)
4) Protein
Lean protein and plant protein are excellent sources of protein that keep the lymphatic and immune system well-functioning without significant risks of inflammation. Examples include:
- Lentils
- Beans
- Chickpeas
- Skinless chicken
- Turkey
5) Omega-3 Fatty Acids
While trans and saturated fats are among the worst foods for lymphatic system function, polyunsaturated fatty acids (PUFAs) are among the best due to their antioxidant properties. One of the best sources of polyunsaturated fats is omega-3 fatty acids, such as those found in Omega Max.
There are three types of omega-3 PUFAs – alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is primarily found in plant oils, while ELA and DHA are found in fatty fish and other seafood. ELA and DHA are more potent than ALA.
Examples of omega-3 fatty acid sources are:
- Fatty fish, such as salmon, mackerel, sardine, tuna, and herring
- Plant oils, such as flaxseed oil, sunflower oil, canola oil, and soybean oil
- Nuts and seeds, including walnuts, chia seeds, flaxseeds, and sesame seeds
6) Nuts and Seeds
Nuts and seeds contain antioxidant vitamins and polyphenols that can help combat inflammation and improve the lymphatic system. Here are some common examples:
- Walnuts
- Almonds
- Pistachios
- Hazelnuts
- Cashew nuts
- Pecans
7) Spices
Different spices contain anti-inflammatory substances that can help the lymphatic system. Aside from reducing inflammation, they can also help in managing the symptoms of lymphatic conditions, such as lymphedema. The typical spices for improving lymphatic health include:
- Turmeric
- Garlic
- Ginger
- Curry
- Cinnamon
8) Supplements
Dietary supplements play a supportive role in nutrition, providing nutrients that a regular diet may not provide. The supplements that will be most beneficial for the lymphatic system are those that are anti-inflammatory and can improve and maintain overall immune health. They include:
- Vitamins (A, B1, B2, B3, B6, B12, C, D, and E)
- Zinc
- Selenium
- Arginine
- Tryptophan
- Glutathione
Choosing a supplement to use is an important step that must be informed by safety and efficacy. One supplement that can help support the immune and detoxification function of the lymphatic system is LipoNano Glutathione™.
This supplement contains glutathione, vitamin E, vitamin B12, sunflower lecithin, and alpha lipoic acid. All of these ingredients are natural antioxidants and have individual effects on reducing inflammation in the body. LipoNano Glutathione™ also lacks additives, reinforcing its commitment to maintaining proper lymphatic function.
Conclusion
The best and worst foods for lymphatic system function generally depend on their effect on inflammation levels in the body.
