Nutrition and Your Brain

Healthy Epigenetic Expression

As we age, our concerns with food choice start to take a shift. We focus less on our waistlines and more on our brains. This may be of particular concern if certain neurological conditions run in your family such as Alzheimer’s or Parkinson’s disease.

It is reassuring to know, however, that a positive history for such neurological disorders does not confirm a future diagnosis. It is estimated that only 10-50% of cases of Alzheimer’s disease can be linked to the known genetic marker APOE4.1 It is estimated that less than 15% of people with a family history of Parkinson’s disease will get this disease.2 Since the actual cause of many neurological diseases cannot be identified, lifestyle interventions, including nutrition, have the potential of impacting our brain function.3

• Protecting Your Brain –In the past decade, epigenetics, or the study of genetics, has revolutionized our understanding of how our food choices negatively or positively alter our neurological health. Epigenetics has shown us that our genes are not our destiny. Food and nutrient choice, food preparation and cooking can impact our genes, and in turn our neurological cell health.

• Gut Health – The role of polyphenols, dietary fiber, folate and fatty acids in correcting our gastrointestinal health can all have an impact on our epigenome and in turn, neurological disease.4,5 Fiber and essential fatty acids support gut integrity that can further impact brain neurochemistry.

• Methylated Nutrients – Modifiable nutrients such as folate can be altered through mechanisms known as methylation, where chemicals called ‘methyl groups’ are added to proteins, DNA and other molecules to activate and keep them inworking order.

• Food Preparation – Not only our food, but food preparation, cookware, and even cooking temperature can affect our neurological health. High heat cooking can produce advanced glycosolated end products resulting in cell death, relating to our brain health. Cookware containing perfluorooctanoic acid (PFOA), containers and plastic wraps containing bisphenol A (BPA) have also been associated with neurological disorders.7

While we cannot avoid all of the insults of our environment, nutritional choices can add to our defense. Utilizing the chemical properties of foods and even certain supplements can further serve as a defense to those aspects of our modern world we cannot control.

One of the most fascinating areas of neuroscience has been the identification of Brain Derived Neurotropic Factor (BDNF). BDNF is a group of proteins that support neurological function and activate the formation of new brains cells. Lifestyle, especially food, can be one of the key areas to add to the production of BDNF. Restoration of BDNF has been associated with improvement in Alzheimer’s, dementia and other disorders of the brain. Even with diagnoses such as these, you can influence the course of your disease.8

The most common question when the topic goes to functional mushroom products tends to be: “Are these magic mushrooms?” Well, this Hawai’i based company is determined to prove that ALL mushrooms are magic. While these aren't psilocybin-containing hallucinogenic mushrooms (most commonly referred to when talking about ‘magic’ mushrooms), their healthful effects are just as remarkable. Mālama Mushrooms is a family-owned business based in Kona, Hawaii, dedicated to promoting health and wellness through the power of superfood mushrooms. Founded by Benjamin Lillibridge in 2015, the brand’s name, "Mālama," meaning "protect, preserve, and nurture" in Hawaiian, reflects the company’s core mission of sharing the healing properties of mushrooms. Residents in the Pacific Northwest are probably most initiated with the wonder of mushrooms. But for those new to the party, welcome! Now let’s give you some ‘mush’ needed context: Mushrooms have been used for targeting a prodigious number of ailments and maladies in traditional cultures medicinal regimes throughout the world spanning millennia. The conventional western world, in their typical resistance to harnessing the holistic capabilities of Earth’s natural intelligence, has been a tad slower to embrace. However, fungi had their historic watershed moment in America during WWII when the power of a lowly fungus, Penicillium spp., was utilized to create the first industrially scaled anti-biotic, Penicillin, and deployed to the allied troops and eventually the rest of the world. This had a dramatic effect on reducing mortality from infections. Today, the literature surrounding fungi such as functional superfood mushrooms such as lion’s mane, reishi, cordyceps & chaga has expanded immensely. Lion’s Mane - Known for its cognitive benefits, Lion’s Mane is often referred to as a “brain booster”. It supports memory, focus, and mental clarity, and has been shown to promote nerve regeneration. Its antiinflammatory properties may also reduce the risk of neurodegenerative diseases like Alzheimer’s and Parkinson’s. Lion’s Mane is a great option for anyone looking to enhance brain health and overall cognitive function for themselves, their family and even their dog! Reishi - Nicknamed the “mushroom of immortality” Reishi is revered for its stress- relieving and immune-boosting properties. It helps calm the mind, improve sleep quality, and strengthen the immune system. Reishi is also known for its anti-inflammatory and cardiovascular benefits, making it ideal for supporting overall well-being. Cordyceps - Cordyceps is celebrated for its ability to boost energy and enhance athletic performance. By improving oxygen uptake and increasing stamina, it’s a popular choice for athletes or those seeking a natural energy boost without a crash. It is also linked to improved lung function and anti-aging benefits. Chaga - Packed with antioxidants, Chaga is a powerful mushroom that supports immune function and combats oxidative stress. It is also renowned for its ability to promote skin health by fighting free radicals and supporting cellular regeneration. Mālama Mushrooms crafts a variety of products that make it easy to incorporate these powerful mushrooms into your daily routine. Whether you’re looking to improve cognitive function, enhance your immune system, or reduce stress, there’s a Mālama product designed to support your health goals. In line with their commitment to quality, Mālama uses organic, fruiting bodies of the mushrooms, a method aligned with traditional practices which does not include any of the oats & rice substrate used in the growing process. But it’s not just obsession with quality that makes Mālama aligned with their namesake of ‘protecting, preserving & nurturing’. The company also donates 5% of profits to the Hawaii Fungi Project, a non-profit dedicated to studying and preserving the native Hawaiian mushrooms, some of which are already on the IUCN’s Endangered Species list and have seldom been seen by human eyes. In addition, during the Maui Fires last year, one of their mushroom farm partners lost 70% of the accounts they sold fresh lion’s mane to overnight. Mālama sprang into action and began dehydrating & extracting their mushrooms to incorporate into their product line and support.
