“Let food be thy medicine, and let medicine be thy food”; a famous quote from the Classical Grecian physician Hippocrates. Lions Mane mushrooms are a perfect embodiment of this philosophy; as delicious as it is therapeutic. 

Lions mane (Hericium Erinaceus) is a white clumpy mushroom with long dangling spines that tends to grow in late summer/early fall on hardwoods.

I was first introduced to Lion’s Mane a few years ago when I had a few patients tell me they were using an extract of the mushroom to help with memory. Supplements that enhance brain activity, AKA Nootropics, have always tweaked my interest as one of my areas of clinical focus is in neurology. At first I thought that maybe this is the newest “superfood fad” but once I began to investigate the research on this mushroom my opinion quickly changed.

It was clear that Lions Mane had some legitimate therapeutic value in inflammation, the immune system, psychiatric conditions, cognitive enhancement, diabetes, heart disease, bowel disease and cancer.

Inflammation and Depression

A 2012 study demonstrated that Lions Mane mushroom contains several compounds that have moderate to high levels of antioxidant capacity. This translates into an anti-inflammatory effect in the body. A 2015 study demonstrated that participants who consumed Lions Mane had less depressive symptoms and improvements in blo-markers of depression which was attributed to it’s anti-inflammatory effects.  Another study demonstrated that Lions Mane can enhance immune function possibly by reducing inflammation and oxidative stress. 

Immune 

Not only does Lions Mane help boost immune function by reducing oxidative stress, it also seems to benefit intestinal immune function. A study on mice revealed that some of the proteins in the mushroom help encourage the growth of beneficial bacteria in the gut. 

Naturopathic Treatment for Multiple Sclerosis

Memory

Cognitive enhancement is the main reason that I see people taking this mushroom. It is possible that it does have some cognitive enhancement properties but all the research so far has been done on animals. One such study found that mice given a lion’s mane supplement had better object recognition and recognition memory. Other research suggests that Lions Mane may have the potential to prevent or treat conditions of cognitive decline like Alzheimer’s and Parkinson’s disease.

Heart Health

Heart Health

Research on rats has demonstrated that Lions Mane may have cholesterol lowering effects and blood pressure lowering effects. Compounds in Lions Mane may help in the production of Nitric Oxide, which helps keep blood vessels relaxed. 

Cancer

The antioxidant properties of Lions Mane may contribute to some anti-cancer effects seen in rat and in vitro studies. One in vitro study indicated that Lions Mane has activity against human leukemia cells. Another study showed that in mice, Lions Mane has activity against Liver, Colon and Gastric cancer cells. 

Diabetes

After 4 weeks of Lions Mane supplementation, rats with diabetes had lower blood sugar levels than those who did not receive the mushroom.  Diabetes can often result in life altering nerve damage. A 2015 study showed that diabetic rats given an extract of Lions Mane had reduced nerve pain and improved antioxidant activity after 6 weeks. 

Intestinal Health

Digestive Health

I previously discussed how Lions mane can have anti-inflammatory effect of the digestive tract, as well as benefitting the growth of “good” intestinal bacteria. Another study demonstrated that Lions Mane has some interesting antimicrobial effects. Notably, Lions Mane seems to inhibit the growth of H-pylori, a bacteria responsible for close to 80% of stomach ulcers.

Nerve Repair

One of the most fascinating health benefits of Lions Mane came out of a rat study. Rats with nerve damage who were given daily extracts of Lions mane had quicker nerve cell regeneration than those who did not. 

Culinary 

Up until a few weeks ago I thought Lions Mane was an exotic mushroom that was only used therapeutically as a supplement.  Recently, I found myself in a local Farmers Market and low and behold a mushroom farmer was selling fresh Lions Mane; I was amazed! I asked the farmer “how do I prepare this”? He told me to cut the mushroom in ½ inch slices and in a hot pan with butter, sear both sides. So, I bought some and followed his advice, and discovered that Lions Mane is absolutely delicious! It is now one of my favorite cooking mushrooms and I have since heard from many foodies and chefs that it is one of their favorites too. So let food be thy medicine everyone, and cook up some Lions Mane this fall!

Cold and Flu season is here! Now that kids are back to school and the season is changing we should start thinking about preventing colds and flu. As a Naturopathic Doctor part of my job is counseling parents on safe and effective ways to treat and prevent colds and flu for the whole family. Here are 5 things that will help prevent colds and flu and can even help to ameliorate symptoms and shorten duration of an active infection.

 

Probiotics

  1. Probiotics

Probiotics help boost the immune system – Studies have shown that probiotics affect immune cells throughout the body. When certain strains of probiotics are introduced into our intestine they help to repair intestinal cells and they boost production of antimicrobial substances. In one study, 326 children aged 3-5 years were randomly assigned to receive, in double-blind fashion, probiotic supplementation. Treatments were given twice per day in divided doses for 6 months, including the winter season. Compared with placebo, the probiotic group had the following results; fever reduction 53-73%, cough reduction 41-62%, decreased runny nose 28-59%, decreased need for antibiotics 68-82%, reduced absence from school 28-32%.

Elderberry

  1. Elderberry

Elderberry extracts inhibit bacteria and viruses – Not only does elderberry syrup taste great, studies have shown that it inhibits the bacteria and viruses associated with common colds and the flu. One study demonstrated that an elderberry liquid extract possesses antimicrobial activity against both streptococci bacteria and influenza viruses. Another study looked at 312 air travellers flying from Australia to an overseas destination.  Those travellers who took an elderberry extract before, during and after travel had fewer colds, less sick days and less symptoms.

Vitamin C

  1. Vitamin C

Vitamin C supports immune cells – Vitamin C is very important for optimal immune system functioning. Vitamin C helps immune cells get to where they need to be, kill pathogens effectively, protect the body from damage and clean up after battling infections. Studies have shown that adequate vitamin C in the blood helps prevent infections, is necessary to fight infections and helps with recovery. The recommended daily intake of vitamin C is 100-200mg/day; however during active infection, the metabolic demand increases and therefore the requirement for vitamin C is likely to be higher. Even in this day and age, vitamin C is the fourth leading nutrient deficiency in North America. Poor diet and increases in free radical exposure due to an unhealthy lifestyle may be contributing factors. Excellent sources of vitamin C are Broccoli, Citrus Fruits and Berries.

Zinc

  1. Zinc

Zinc is essential for immune system communication – The importance of zinc for proper immune function has been well established. Zinc deficiency undoubtedly causes immune system malfunction.  The cells of our body are in constant communication. During infection there is a need for effective communication between immune cells in order to get rid of the “bad guys”.  Communication happens in the form of chemical messengers and enzymes. Zinc is an essential component of these chemicals and enzymes. As with vitamin C, during active infection our requirement for zinc is likely to increase. Studies have shown that Zinc supplementation during infection can shorten the duration of the illness. Excellent dietary sources of zinc include: Meat, Shellfish, Legumes, Nuts and Seeds. Supplementation may be important with a vegan or vegetarian diet.

Vitamin D from Sunlight

  1. Vitamin D

Vitamin D is the supervisor of the immune system –Vitamin D has many functions in the body, and receptors for vitamin D can be found on many different tissues. One important function for vitamin D is in the modulation of our immune system. Studies have suggested that vitamin D is able to both calm down and rev-up the immune system according to what our body needs it to do. This is why Vitamin D is thought to be as important in autoimmune disorders as it is in infections.

Vitamin D deficiency can cause the immune system to behave erratically. Unfortunately in Canada we have one of the highest incidences of vitamin D deficiency in the world. Our primary source of vitamin D is from sunlight and therefore supplementation becomes important especially during the winter months. Studies have shown that there is a higher incidence of upper respiratory tract infections in athletes who are deficient in the vitamin and who train in the wintertime. Supplementation had preventative and symptom reducing effects. Aside from sunlight, some dietary sources of vitamin D are: fortified foods, fatty fish, beef liver, egg yolks and cheese.

 

Even vitamins and minerals at high dosages can be dangerous, especially in children. It is always recommended to consult with a health care professional, such as a Naturopathic Doctor, before supplementing on your own.

It’s the summer of 2018 and it’s a hot one. Having fun in the sun is what we dream about all winter long and while we do benefit from some sun exposure (boosting levels of vitamin D and serotonin) we must also balance sun exposure with sun protection. In this article I will outline some general guidelines with reference to safe sun exposure, getting enough vitamin D and how consuming certain foods may help further protect us during recommended exposure times.

Exposure

According to recent research we now know that vitamin D is not only important for strong healthy bones but also plays a role in preventing some chronic diseases like Multiple Sclerosis and Cancer. So we need to know some general guidelines for getting the right amount of sun exposure while helping protect ourselves from damaging UV radiation.

In 2001 the Australian Radiation Protection and Nuclear Safety Agency set out to determine daily UV radiation levels in major cities across Australia. How much sun was needed to produce adequate levels of vitamin D and how much exposure could produce damage to the skin was investigated. The general guidelines to come out of the report were as follows: In the peak of the summer, July and August in North America, “2 to 14 minutes of sun three to four times per week at midday will give fair-skinned people with 15 per cent of the body exposed the recommended amount of Vitamin D. However, redness (skin damage) can occur in only eight minutes in these conditions.

So in peak summer times from 10 am to 3pm, you should use protection against the sun; shade, hats, clothing, sunglasses and sunscreen.

But earlier in the day and later in the afternoon, for a similar period of sun exposure and vitamin D manufacture, you get much less skin damage.”(http://www.abc.net.au/health/thepulse/stories/2006/04/05/1609208.htm)

For the months just before and after the peak summer months (June and September) the study revealed that the time of sun exposure needed for adequate vitamin D levels increases to 10 to 15 minutes 3-4 times per week. In the fall, winter and early spring months we need short periods of exposure during peak times of the day 10am-3pm in order to make enough vitamin D.

Sun-Blocking Foods

The question then becomes; in those times of recommended sun exposure how do we further protect ourselves from the damage of UV radiation? Part of the answer may be in the food we eat and beverages we drink. UV radiation helps us to make important compounds such as vitamin D but it can also cause damage to our cells. Cellular damage occurs via the production of inflammation and damaging compounds called free radicals. Some important compounds in our diet that combat inflammation and free radicals are: Omega-3 fatty acids and Antioxidants.

Antioxidants are compounds found in fruits and vegetables that serve to protect the plant against the harmful effects of its environment, including UV radiation. Many of these antioxidants incur the vibrant colors we associate with fruits and vegetables onto them.

Lycopene is a powerful antioxidant found in red colored fruits and vegetables such as: Tomatoes, Watermelon, Guava, Grapefruit, Papaya and Red Peppers including Chili Pepper. Lycopene is most easily absorbed when it has been cooked, making tomato paste and cooked tomatoes an excellent source of bio-available lycopene. Not only does this antioxidant protect the fruit/vegetable from UV damage, when we consume lycopene, it protects our body as well.

Anthocyanidins are a group of antioxidants that incur free radical protection and have a dark red or purplish color. Rich sources of anthocyanidins include: Blueberries, Acai, Pomegranate, Blackberries and Cherries.

The flavonoid antioxidants in green tea include the very powerful polyphenol EGCG. EGCG has not only been shown to inhibit tumor cells in some cancers but has also been shown to protect cells from the aging effects of UV radiation. Particularly matcha green tea (pulverized powdered tea leaves) can be 137 percent higher in EGCG than regular water infused tea leaf. Dark chocolate is also very high in phenols and can incur a 25 percent increase in sun tolerance at 2 ounces of over 70% cacao per day.

Another compound important for protecting our body against the potentially harmful effects of sun exposure are omega-3 fatty acids. These fatty acids help to drive an anti-inflammatory pathway in the body. Radiation and chronic disease induces inflammation which can lead to cellular damage and premature aging. Fish is an excellent source of omega-3 fatty acids, particularly Salmon, Herring, Mackerel, Trout and Sardines. It is recommended to eat at least 2 servings of high omega-3 fish per week or to take a fish oil supplement daily.

Another good source of omega-3 fatty acids are flaxseeds. Flaxseeds also contain compounds called lignans which may protect against the development of some cancers. It is recommended to have a half teaspoon of ground flaxseeds per day or a flaxseed oil supplement.

Although these are all specific examples of foods rich in sun protecting compounds, a good general rule of thumb is too eat plenty of vibrantly colored fruits and vegetables which will undoubtedly be rich in antioxidants. It is also just as important to limit foods which can cause free radical damage and inflammation, these include: sugar and red meats.

Equip your body with sun protecting foods and follow the guidelines as to when to allow for uninhibited sun exposure. By doing so you will make the D and be problem free.
