In our last post, the curious adventurer, we mentioned how eating right plays an enormous role in your ability to finish a thru hike. Pain is undoubtedly a common ailment experienced by most thru-hikers. Fortunately, nature has provided us with plenty of trail worthy foods to help minimize and alleviate inflammation and pain.
This doesn’t mean you should toss “vitamin I” (aka Ibuprofen) from your medicine kit; keep a reserve supply for severe pain. However, eat enough of the anti-inflammatory foods discussed here and you may never need an over the counter (OTC) pain reliever. Or, combine these foods with your OTC drug for a double whammy.
First, what is Inflammation?
Inflammation is derived from the Latin word “inflammo” meaning “I ignite.” The term characterizes the burning or heat sensation characteristic of inflammation. Inflammation is the body’s response to harmful stimuli, such as irritants, injury, and infection. The signs of inflammation are pain, a feeling of burning, redness, swelling, and loss of function.
Inflammation can either be short-term (acute) or long-term (chronic).
- Acute inflammation is the body’s first response against damage caused by physical injury. Examples of acute inflammation include an insect bite, hives, an injury such as a stubbed toe, burn, cut, or splinter. A healthy body can usually heal itself from acute inflammation within a few hours or days.
- Chronic inflammation happens when the body is continuously exposed to irritants and becomes chronically inflamed, leading to suppressed immunity and risk for serious illnesses. The prolonged inflammation interferes with the body’s normal biological processes and over time leads to a weakened state and potential for cells to mutate and attack the body. For example, autoimmune diseases such as rheumatoid arthritis, celiacs disease, and IBS.
The process of inflammation goes something like this
First, you get a splinter. Cells get damaged, and foreign pathogens enter the body (a tiny splinter can contain billions of bacteria). Pain acts as the signal for this microbial invasion. Mast cells immediately begin releasing histamine and cytokines to alert the body of damage. Small blood vessels respond by developing leaks, which allow the immune cells to gain access to the injured area. Meanwhile, neutrophils begin attacking bacteria and damaged cell tissue. Lymphocytes then intensify the healing power of the immune system. As the bacteria is destroyed, platelets and other substances form clots to close up the wound. This is a healthy response to inflammation.
Problems can develop when inflammation becomes chronic (from poor nutrition, long-term stress or illness, underlying long-term infection) or the immune cells mistakenly attack healthy cells in the body. Fortunately, some foods can help with healing of this process.
Most plant-based foods are naturally anti-inflammatory.
Not only will consuming these foods help with acute inflammation, but they’ll also help prevent chronic inflammation. Here are a few of the biggest anti-inflammatory food winners that can also be used for the trail (or added to your spice kit).
Best anti-inflammatory foods
Ever wonder why prepared mustard is yellow? The color comes from a spice called turmeric. Turmeric, a member of the ginger family, is a golden yellow root that is native to India. It is commonly dried, ground into a fine powder, and sold as a spice. It has a long tradition for its healing properties, use as a seasoning (especially in Indian curries), and as a skin dye for important ceremonies. Turmeric is a complex medicinal food which contains many known active beneficial constituents.
Why it works for pain & inflammation
Turmeric contains a mixture of phenolic compounds; the key one is curcumin, a potent anti-inflammatory substance. This compound inhibits cyclooxygenase-2 (COX2), an enzyme in the body that becomes elevated with inflammation, especially from joint pain and stiffness caused by arthritis. In fact, some people find turmeric capsules offer better relief for their osteoarthritis than the drug Celebrex.
For pain, curcumin has been shown to be just as effective as Ibuprofen, but without any toxic side effects. Common OTC non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen and naproxen can cause adverse gastrointestinal side effects, increased heart failure, or inhibited blood clotting. Turmeric has no such side effects. Curcumin is also antiviral and helps speed up the healing of wounds. You can dab it directly on a wound as an antibacterial before adding a bandaid.
Turmeric may provide further pharmacological benefits. It has demonstrated positive results in preventing health conditions such as Alzheimer’s, MS, and cancer. Research is underway to study how these complex synergistic interactions work together to make it such a valuable herb.
How it tastes
Turmeric spice has a warm aromatic zest and a mildly bitter and peppery flavor, reminiscent of ginger.
Add about one teaspoon per day of powdered turmeric with food. Increase your intake by adding an extra squirt of mustard on sandwiches. Start sprinkling turmeric spice on rice, soups, pasta, eggs and potatoes. Add it to hot teas. Add turmeric with black pepper to enhance the absorption of curcumin. For more severe pain, add up to 5 teaspoons of turmeric per day.
Ginger is another underground rhizome in the same plant family as turmeric. Beneath the outer bark, is the edible striated, creamy inner flesh. Ginger is an exceptional antidote due to its antiseptic properties and pain relieving qualities. It is one of the oldest and noteworthy spices, long prized for its sharp flavor and stomach soothing qualities. Gingerbread making started during medieval Europe and its inclusion to beer or ale (ginger ale) from 19th century England. It remains the go-to treatment for motion sickness for many people, and frequently outperforms the OTC drug Dramamine.
Ginger is commonly used fresh, but is also sold dried as a spice.
Why it works for pain & inflammation
Ginger is a powerful pain reliever. A study by the University of Georgia showed ginger consumption can reduce muscle soreness by up to 25 percent for an entire day. Like turmeric, ginger contains COX-2 inhibitors which suppress these pain-causing enzymes in the body during inflammation.
Ginger contains chemicals called gingerols and shogaols that soothe an upset stomach and aid digestion. It improves digestion by increasing wavelike muscle contractions, called peristalsis, that move food through the intestine. These substances also suppress coughs, relieve pain and reduce fevers.
Zingerone, the active substance released in cooked or dried ginger, destroys E.coli and relieves the diarrhea associated with it.
How it tastes
The flavor of ginger varies depending on where it is grown. Overall, it has a bright, citrusy aroma and a spicy-sweet, peppery flavor.
Add about one teaspoon per day of powdered (2 TB of fresh ginger) with food after hiking or exercise. Increase your intake of ginger by adding the spice to sweet no-cook desserts, such as chia seed puddings. Sprinkle it on trail mix. Eat candied ginger. Add it to hot oatmeal. Sprinkle it liberally over rice, pasta, soups or sprouts. Stir it directly to hot or cold water, tea, or coffee to soothe stomach distress or pain. Drink ginger ale when in town – check the ingredients to make sure it contains actual ginger (many do not).
Garlic has been used as both food and medicine for thousands of years. Garlic is part of the allium family of vegetables along with onion, leeks, and scallions. The health benefits of alliums are outstanding. Their high concentration of antioxidants and flavonoids stimulate immune response and reduce inflammation. But garlic takes the prize for the broad-spectrum health benefits it offers, which include antibacterial, antiviral, anti-inflammatory, and antifungal activity.
Why it works for pain & inflammation
The star compound in garlic is Allicin, which is released when garlic is cut or crushed. The allicin has antibacterial properties equal to weak penicillin.
Garlic (and other alliums) contains a high amount of sulfur, the substance responsible for their pungent smell. Sulfur is beneficial for healing – it is an oxygen carrier and works by carrying oxygen in the body directly to infected areas; since germs can’t live in an oxygen rich environment, the infection clears. As sulfur compounds are metabolized in the body, they form into allyl methyl sulfide, which is absorbed into the blood stream and lungs, escaping through exhaled air and perspiration. Thus, the cause of garlic breath.
Garlic contains other properties which help decrease blood pressure, detoxify chemicals, improve circulation, prevent tumors, and boost immunity. Hence, it is useful against everything from fighting off the common cold to athletes foot to worm infestations. Develop a funky fungal infection on your foot while hiking? Eat more garlic! Since garlic is excreted from our sweat, it can work from the inside out.
How it tastes
Spicy. Allicin is the substance that gives raw garlic the “hot” taste sensation on the tongue. The aroma released while cooking garlic helps too — it smells as sensational as it tastes. Are your taste buds wetted, yet?
Cooking does not diminish the protective effects of garlic or other alliums. Boost the flavor of spreads or dips, rice meals, pastas, potatoes, and breads by sprinkling with garlic powder or garlic salt. Or, look for backpacking meals that contain garlic. Also, forage for wild likes (ramps) while on the trail – they are abundant across most of the United States. You can add fresh ramps directly to pasta and rice meals. How to identify wild leeks or ramps during different seasons and harvest in a sustainable way.
Chili peppers, native to South America, are one of the most widely grown peppers in the world. The fruits grow on small shrubs and vary in taste and potency.
Chilies contain a resinous substance known as capsaicin, which is a powerful anti-inflammatory and painkiller. The burning sensation comes from capsaicin, which is a defense of the chili pepper to protect the seeds from being eaten by mammals. The burning sensation is painful to all mammals; however birds are immune to the substance.
The effects of capsaicin vary depending on the type of pepper and the growing conditions. Red or Cayenne Pepper is one of the best suited for pain relief.
Why it works for pain & inflammation
Capsaicin triggers the body to release natural pain-dulling chemicals called endorphins. Besides being potent COX-2 inhibitors, hot peppers also contain natural analgesic salicylates (aspirin-like compounds), a pain reliever and anticoagulant. Peppers are also high in vitamin C, an important nutrient that is often lacking in the diet of most thru-hikers due to their reliance on dried foods.
Cayenne is an excellent pain killer when applied topically (capsaicin is absorbed through the skin). When the crushed peppers are applied to the skin, capsaicin depletes substance P, a chemical in nerves that transmit pain sensations. You can purchase chili peppers, mash them up, and apply directly to the area of pain. You can also mix dried cayenne pepper (spice) with olive oil and apply directly to the skin. Leave on the skin and wrap it with your bandanna. Make sure you clean your hands before touching your eyes!
How it tastes
Chili peppers are oily and potent. The varieties are classified according to their relative pungencies or scoville units, with bell peppers containing the least amount of hotness and Habanero containing the most.
Add more hot sauce and salsa to your diet! Look for foods that contain red chilies, red pepper, cayenne, chipotle, chili powder, jalepeno, bell pepper, or hot peppers.
Spicy foods are also particularly suitable for thru-hikers because they help prevent dehydration by stimulating thirst. It has a cooling effect in hot climates, making us feel warmer than we are, and inducing the cooling mechanisms (sweating, increased blood flow to the skin).
Omega-3 Fatty Acids
Omega-3’s act as a lubricant for joints. A diet high in these polyunsaturated fats oils will fight inflammation, especially in joints and cartilage. Omega-3 fats are found in flaxseeds, walnuts, cashews, chia seeds, hemp seed, olive oil, soy, and fatty fish. Be cautious if consuming fish–those that have the most healthy omega-3 fatty acids, such as tuna, also tend to have the most unhealthy toxic accumulations. If you must consume fish, the best choices are cold water fatty fishes such as anchovies, sardines, rainbow trout, and mackerel (until they become farmed/over-fished).
Note: Only plants synthesize omega-3 fats; fish concentrate the pre-synthesized oils in their bodies in the more efficient form, DHA and EPA; this form does not just come from fish, it can also be obtained directly from algae oil (likely a safer choice too). Plant sources high in omega-3’s include –
Chia Seeds are rich in Omega-3 and anti-inflammatory properties, and help reduce swelling and lubricate joints. It also offers an energy increasing property that does not act as a stimulant and is high in calcium. We highly recommend taking chia seed for the trail. Chia seeds do not require refrigeration, do not need to be ground to obtain their beneficial nutrients, and contain more omega-3 fat than flax seed. Once ounce (2 TB) provides 165 calories.
Walnuts are an excellent source of Omega-3 fats, one of the highest of any tree nut. While most nuts are high in monounsaturated fatty acids, walnuts contain a high amount of polyunsaturated fat in the form of alpha-linolenic acid (ALA), a type of Omega-3 fatty acid. Interestingly, the walnut half bears a resemblance to the human brain, and its nutrients are excellent for brain health and memory. Walnuts are a good source of serotonin, which helps curb appetite and fight depression. Because walnuts are high in calories, they are excellent for energy. One ounce (about 14 walnut halves) provides 165 calories.
Olive Oil, in particular, extra virgin olive oil (EVOO), contains a valuable source of antioxidants and various anti-inflammatory polyphenols. These substances reduce inflammation, especially in the cardiovascular system and joints. The polyphenol, oleocanthal, which is responsible for the peppery “bite” of extra virgin olive oil, has shown to reduce pain by inhibiting the activity of COX-1 and COX-2 enzymes. Olive oil is sold by grade, which represents the amount of processing. Extra virgin olive oil is from the first pressing of the olives and has the best overall health benefits. One ounce ( 2 TB) of EVOO provides 240 calories.
Sunflower seeds do not contain much omega-3 (they are higher in omega-6), but are worth mentioning because they contain a high concentration of phenylalanine. Phenylalanine reduces pain by inhibiting the breakdown of enkephalins, chemical pain receptors. Consume a handful of seeds per day. One ounce (about 3 TB) of sunflower seeds provides 160 calories.
To increase your intake of all these omega-3 foods, add the nuts and seed together with cold or hot cereals. Walnuts taste great when added to pasta and topped with olive oil.
While low in calories, the berries commonly found growing in the United Sates, such as blueberries, all contain high levels of antioxidants and anthocyanins, nutrients known to relieve pain and inflammation. Berries are also an excellent source of vitamin C. The darker the berry, the better.
Berries, dark red or blue are due to the red pigment, anthocyanin, found in many purple, red and blue pigmented berries. This includes raspberries, blackberries, blueberries, black currants, tart cherries, red grapes, black chokeberries, cranberries, and elderberries. Along with providing the red pigment, these phytonutrients are potent antioxidants, capable of reducing inflammation at levels comparable to OTC pain medications. Do not eat wild berries on the trail unless you can positively identify what it is – 50% of wild red berries are poisonous.
Bananas are full of potassium, an essential nutrient used to maintain fluid and electrolyte balance in the body. We lose potassium through sweat and muscle burning when we exercise, and loss of potassium can contribute to fatigue, muscle aches, and pain.
Note: the substance bromelain, found in pineapple, is commonly cited as an anti-inflammatory; we did not find enough evidence confirming that claim, and therefore, can not recommend it for this purpose.
So, now you know what to eat to minimize the pain. Does that mean you will not experience any pain if you eat these foods?
The most physically fit hikers will still feel muscle pain and soreness at the end of a long day. No matter how good your diet. But a bad diet will make you feel much, much worse. Diet can make the difference between finishing or failing a thru-hike. So, why not eat foods that can improve your health and performance?
What else can you do? If you are feeling a little adventurous (or desperate!), try to supplement with what is available along the trail.
Use what is found on the trail
Cold water – water is the ultimate healer and is very effective for reducing inflammation. The colder the water, the better. Cold water helps clear inflammatory biological markers such as creatine kinase and the cytokines. Give your achy, swollen feet a good 20 minute soaking in a cold mountain stream.
Rocks – cool smooth rocks can help with neck and joint pain by reducing swelling.
Bark from trees containing salicylates, such as White Willow, Birch, Aspen or Popular. The most common natural pain reliever in the wilderness is to use the inner bark of a tree that contains the salicin compound, the same ingredient in aspirin; unlike aspirin, these do not thin the blood or irritate the stomach. Gather bark from branches of a tree and strip the bark from the cut branches. Do not strip bark from the trunk of a tree.
Note: White willow (Salix alba) contains the most salicylic acid. Making pain relief from bark should be used for emergency situations only. Do not do this if you are 1) allergic to salicylates 2) do not know how to identify trees 3) do not know the proper dosage 4) are already taking a salicylate-containing drug, such as Coumadin. How to make aspirin from tree bark (aspen in this case).
Nettle – leafs from the stinging nettle plant is another wild edible plant with pain relieving properties. The active compounds in the leaf suppress inflammatory cytokines. Be careful when gathering the leaves or wear gloves, because the leaves contain fine, fuzzy stingers. And don’t worry, the stingers become soft and edible when cooked. Nettles are also high in vitamin C. How to identify stinging nettle
Mint – both mountain mint and peppermint contain active chemicals that relieve pain. Mountain mint is high in pulegone, a chemical similar to capsaicin. Peppermint contains menthol, which contains pain relieving qualities. Use it to make a tea or add chopped leaves to flavor meals.
Ramps or wild leeks – provide pain relief and add flavor to dishes. Add fresh ramps directly to pasta and rice meals. How to identify wild leeks or ramps during different seasons in a sustainable way.
We cannot end without saying the most important thing you can do for better health and hiking performance: do not eat inflammatory causing foods.
Examples of foods which promote inflammation and should be avoided
- Meat – After exercise, our body uses protein to repair itself. The amino acids in protein are the building blocks for this process. But, meat is difficult to digest and too much protein can lead to increased pain. Instead, focus on eating carbohydrates from whole grains, vegetables, and fruits instead, which also supply us with protein. The sugars in these foods work with the proteins to build muscle. If we do not eat enough carbohydrates, our muscles will cramp and ache. So, eat quinoa or brown rice with veggies instead!
- Saturated and trans fats – found in everything from ice cream to margarine to bacon. Of the two, trans fats is the worst to consume.
- Refined sugar and white flour – These simple carbohydrates are empty of nutrients and increase your levels of pro-inflammatory compounds. Skip the Little Debbie cakes and you’ll feel better.
- OTC anti-inflammatory drugs such as Ibuprofen do alleviate pain (and are okay for isolated acute pain), but long-term reliance on them can lead to larger problems, such as gastrointestinal bleeding, kidney impairment, and cardiovascular incidents. Athletes who take anti-inflammatories before or during exercise caan increase inflammation and reduce performance.
