The human body naturally processes toxins as people inhale air, eat food and drink beverages throughout the day. However, things can get backed up. Sometimes, people experience clogged lymph nodes, which may be managed by consuming foods that support lymphatic drainage.
A holistic approach involves not only eating the best foods for lymphatic drainage, but also knowing which ones to avoid. Understanding these key components and adopting simple habits are essential for better caring for your lymphatic system and overall health.
The lymphatic system is a complex network of tissues, organs and vessels that collaborate to move watery fluid called lymph back into your bloodstream. This network is vital to your immune function, protecting you from infection and eliminating cells that are no longer necessary to your body.
This system has lymph vessels that process toxins throughout the body. When they become clogged with waste, the vessels can’t function properly. Toxins build up, leading to malnourished white blood cells and potential disease.
Lymphatic blockage can manifest in many ways, including:
These are some foods that help promote lymphatic drainage. Consider adding a few to your diet to better support your physical health.
Plants like kale, lettuce, spinach and other leafy greens have higher amounts of chlorophyll. This phytochemical helps protect the body from certain carcinogens by binding to toxins as it passes through the digestive system.
Although it’s important to know which foods to avoid with swollen lymph nodes, eating more leafy greens may help your body to reduce your symptoms and prevent them from becoming clogged again. Each bite introduces more chlorophyll into your system, which helps your lymph vessels fight toxins.
Chia seeds are packed with omega-3 fatty acids, so they’re a significant source of the healthy oil. Omega-3s reduce inflammation, which can cause lymphatic blockages and keep them in place.
Consider mixing chia seeds into your next bowl of oatmeal. They’ll assist your lymphatic system, while oats help regulate your blood sugar and soothe your body into a less inflammatory state.
Some lymphatic blockages contain fat and toxin buildup. Cranberries contain arbutin, which helps reduce inflammation and supports the body in clearing out unhealthy fats.
Mix a few cranberries into Greek yogurt to boost your protein intake while providing your body with antioxidants that fight lymph vessel blockages. You can also sip on cranberry juice, as long as it’s organic and not the high-sugar processed juice alternatives.
You’ll find flaxseed in products like flours and cereals. It’s a food high in antioxidants and alpha-linolenic acid, which may help boost your heart health. Eating more food with flaxseed as a primary ingredient can further boost your body’s ability to process and prevent lymphatic blockages.
People enjoy the smooth texture of avocados on their food because the fruit has essential fatty acids. They’re the same fatty acids found in chia seeds. Improve your healthy fat intake by eating more avocados when you experience lymphatic drainage problems. Add them to tacos and burritos, or spread on toast.
The garlic in your favorite meals is another helpful tool against lymphatic buildup. It contains allicin, a compound with antimicrobial properties. Add it to salad dressings, buttery dips and sauce-based meals to help your lymph vessels with the double-packed power of garlic.
Keeping your lymphatic system healthy and fully functioning requires an anti-inflammatory diet. Here are some food sources to avoid.
While butter, deep-fried foods, bacon and milkshakes may all sound appetizing, these contain high amounts of saturated fat, which can have significant negative effects on your lymphatic system. Excessive consumption of these foods may also increase oxidative stress, hindering the efficient drainage of waste products.
Pasta, rice and white bread are often touted as staples. However, they are carbohydrate-rich and may spike glucose levels, which can worsen lymphedema in some cases. Unless you’re carb-loading for a half-marathon to maximize your performance, make sure to consume these foods mindfully.
Processed foods are among the worst for the lymphatic system. Sweetened breakfast cereals, chicken nuggets, hot dogs and instant noodles contain unhealthy fats, which can hinder your lymphatic system’s ability to fully perform its functions. They lack sufficient nutrients for a balanced diet.
Salty foods put more pressure on the lymphatic system, making it harder to clear waste from the body. Too much salt causes immediate water retention, which may also lead to bloating.
Excess sugar may impair proper lymphatic flow, slowing fluid movement. It can also increase insulin resistance, allowing glucose to remain in your body longer. Eventually, your organs, including your lymph nodes, may not keep up if your blood sugar continues to rise.
Acrylamide is a chemical usually found in starchy foods, such as french fries, potato chips and coffee. It also occurs in foods cooked at temperatures above 120° Celsius, including fried, roasted and baked meals.
While a healthy diet is foundational, you can enhance your body’s ability to cleanse its lymphatic system by incorporating a few simple, daily practices.
Here are answers to questions about the lymphatic system and an anti-inflammatory diet.
There are many methods to improve lymphatic drainage in your legs. You can do physical activities, get a lymphatic massage, do compression therapy or simply elevate your legs. Usually, the cause of lymphatic swelling is inactivity and poor circulation. Movements are generally the best way to go about relieving the blockages.
Walking, yoga, swimming and light stretching all count as good lymphatic system exercises. Gentle, rhythmic movement helps push lymph fluid through your vessels.
There isn’t strong clinical evidence that lymphatic drainage drops do much for lymphatic function on their own. Talk to your doctor before trying them.
If you’re wondering what food helps lymphatic drainage, start with a balanced diet rather than expecting a single ingredient to clear a blockage. You could also schedule a quick visit with your doctor to discuss your options. There are many ways to relieve swollen lymph nodes, especially if you’re looking for at-home remedies. It may take some trial and error, but you can find relief.
