cognitive benefits of curcumin

Cognitive Benefits of Curcumin

/in /by

The daily consumption of curcumin, the active compound in turmeric, can have significant benefits on cognitive health.

According to the National Institutes of Health (NIH), more than 88 million Americans over the age of 65 will be diagnosed with neurodegenerative disease by 2050. The progression of neurodegeneration has been associated with the imbalance between the level of antioxidants and the increased oxidative damage by free radicals to proteins, DNA, and lipids.

Curcumin is a chemical compound found in plants, with anti-bacterial, anti-inflammatory, anti-proliferative, and antioxidant properties. Research has seen an astounding success proving the benefits of curcumin as an antioxidant and anti-inflammatory, with over 7000 articles published in the last two decades. Its neuroprotective properties help prevent free radical damage and calms the inflammatory process at the root of many chronic diseases. Studies have shown it to be effective against many gastrointestinal diseases and metabolic diseases such as diabetes and obesity, certain cancers, cardiovascular disease, and neurodegenerative diseases such as Alzheimer’s. In fact, curcumin has long been suspected to be the reason behind the low rates of Alzheimer’s disease in India, where turmeric spice is widely and frequently used in curry meal preparation.

However, curcumin is unique in that it is not easily absorbed by the body on its own. In order to increase its bioavailability, it must be paired with other compounds, one such example is piperine, a compound found in black pepper.

But for those who don’t have a taste for this beautiful golden spice, supplementation can be key. Research on the supplement Theracurmin* a bioavailable (more easily absorbed by the body) form of curcumin, has shown it contains significantly higher plasma concentration of curcumin than other leading brands of supplements. Clinical studies have also shown it to have benefits in osteoarthritis, muscle fatigue after exercise, and clearing alcohol metabolites. There are on-going clinical trials investigating the effects of Theracurmin on other inflammatory diseases.

A 2019 study on curcumin, led by Dr. Gary Small, director of geriatric psychiatry at UCLA’s Longevity Center, was conducted over an 18 month period and included 40 adults that ranged in age from 51 to 84. Twenty-one randomly selected participants were given twice daily doses of Theracurmin, and the remaining 19 participants were given a placebo. Cognitive assessments were taken every 6 months and curcumin levels were measured at both the start and end of the study. In addition, 30 participants (15 placebo & 15 curcumin) underwent PET scans to measure levels of the proteins amyloid and tau in their brains both at the start of the study and after 18 months. These two proteins are targeted because of their association with neurodegenerative disorders; when accumulated in the brain, they are thought to contribute to the breakdown of neurons which can potentially lead to symptoms of Alzheimer’s disease.

At the end of the study, researchers concluded that the daily intake of Theracurmin resulted in “improved memory performance and attention in non-demented adults.” Based on the PET findings, the study further concluded that “behavioral and cognitive benefits are associated with decreases in plaque and tangle accumulation in brain regions modulating mood and memory.”

While this study was quite small, the results are indeed promising and warrant continued research. Supplementation with a bioavailable form of curcumin, like Theracurmin, shows tremendous potential as a preventative measure against age-related cognitive decline. Furthermore, the effect curcumin has on decreasing existing amyloid plaque and tau accumulation in the brain shows that it may play a significant role in delaying the onset of other neurodegenerative diseases such as Alzheimer’s dementia.

As research continues to reveal turmeric’s bounty of health benefits, including its ability to limit and possibly reverse the damage of inflammation in the brain, it is becoming more and more evident why it is widely referred to as a miracle spice!

Before taking any supplement consult with your physician to discuss any potential side effects.

Healthy omega 3 fats

Build a Healthier Brain With Fat!

/in , /by

We don’t usually associate increasing the amount of fat in our diets as a way to improve health, but when it comes to a particular type of fat, that’s exactly what the doctor ordered!

Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs), a type of essential fat involved in several metabolic processes, and they are a crucial component of good health.

Research shows omega-3 fatty acids reduce inflammation and may reduce the risk of chronic diseases such as heart disease, cancer, and arthritis – conditions that often have a high inflammatory process at their root. But most impressive is the research that confirms Omega-3’s benefits on the brain.

There are 11 different types of omega-3s, but the most well-known for their beneficial properties are Alpha-linoleic acid (ALA), Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA).

Dietary sources of ALA, DHA, and EPA

The modern American diet is typically low in Omega-3 and high in Omega-6 fatty acids, another form of polyunsaturated fatty acid found in some vegetable oils (like corn, soybean, and cottonseed oils), nuts and seeds. Too much Omega-6 causes inflammation; therefore, avoiding processed foods that contain them is important. Interestingly, too much Omega-3 can also be bad; it’s all about keeping the ratio of Omega-3 to Omega-6 in check.

A well-balanced diet with natural sources of ALA, DHA, and EPA is fundamental to maintaining a healthy ratio that prevents inflammation and promotes long-term health.

DHA and EPA are found in fatty, cold-water fish, such as salmon, trout, cod liver, herring, mackerel, and sardines, as well as shellfish such as shrimp, oysters, clams, and scallops. Fish is the best source of Omega-3s as DHA and EPA are more bioavailable, meaning it is easier for the body to absorb it over ALA. Whenever possible, purchase wild-caught fish and check out SeafoodWatch.org to see which fish are lowest in mercury and other environmental toxins.

ALA comes from plants and is the most largely consumed form of Omega-3 in the typical American diet. It serves as an energy source for our cells and a small percent is converted into DHA and EPA. Dietary sources of ALA include flax seeds and flax oil, walnuts and walnut oil, chia seeds, pumpkin seeds, hemp seeds, and hemp oil, mustard oil, most leafy green vegetables, and tofu.

Some research is being done on algal oil, as it contains both DHA and EPA making it more bioavailable than other plant sources of Omega-3s. For vegans and vegetarians, this may be a promising alternative to fish oils. Some supplement brands have already started creating vegetarian EPA/DHA supplements from algal oil for those who prefer not to take fish oils.

Supplementation

When diets don’t meet the mark, supplementation may be recommended, but should always be done under the supervision of a doctor and dietitian for these reasons:

1) A doctor and/or a dietitian-nutritionist can monitor the ratio of Omega 3:6. Certain health conditions may benefit from additional Omega-3; in this case, proper dosage should be determined by a doctor.

2) When a diet is already rich in Omega-3, supplementation may throw a proper Omega 3:6 ratio off-balance and unintentionally cause inflammation.

3) There are some supplements of omega-3 that are actually inflammatory. Many retail brands of Omega-3 or fish oils come from sources of fish that are fed an atypical diet of corn and soy, which alters the composition of fatty acids in the fish oil. This can cause inflammation. As supplements do not require FDA approval, a dietitian or doctor can recommend a trusted brand.

Effects of Omega-3 Fatty Acids on the Brain

– Neuropsychiatric conditions: Research shows that Omega-3 fatty acids can be effective in treating depressive conditions, such as Major Depressive Disorder and bipolar disorder.

– Post-stroke & post-concussion: A study published in the Journal of American College of Nutrition found that giving DHA post-concussion helps in the repair and recovery from injury.

A 2015 study published in the Journal of Neuroimmunology found evidence that supported the clinical use of Omega-3 in treating “stroke and other acute neurological diseases” due, in part, to its anti-inflammatory and anti-apoptotic (prevention of cell death) properties.

– Neuropathic pain: Neuropathic pain, or pain due to damage of the peripheral or central nervous system, can cause debilitating pain for those affected.

A 2018 study found that patients with neuralgic pain who were treated with omega-3 fatty acids in conjunction with conventional medicine, reported more improvement in pain intensity and quality of life than those who received conventional medicine alone.

In 2010, a review of case studies found that patients with neuropathic pain who were treated with high doses of Omega-3 fish oil had “clinically significant pain reduction” and improved function.

– Migraines: Diets high in Omega-3 fatty acids have been found to lessen the frequency and occurrence of migraine headaches.

– Neurodegenerative disease: DHA is extremely important for brain development and function. Studies show that when DHA levels are low, the brain is more susceptible to degeneration.

Omega-3 fatty acids help scavenge free radicals (atoms, molecules, or ions with unpaired electrons) that attach inappropriately to tissue and damage it.

A study published in The FASEB Journal found that “omega-3 polyunsaturated fatty acids, which are found in fish oil, could improve the function of the glymphatic system, which facilitate the clearance of waste from the brain, and promote the clearance of metabolites including amyloid-β peptides, a primary culprit in Alzheimer’s disease.”

Studies also show that DHA supplementation can improve cognitive performance.

How much is enough?

Eating a Mediterranean diet with plenty of fruits, vegetables, whole grains, nuts, lean meat, and cold-water fish will help a person consume more Omega-3’s on a regular basis. Current literature advises that at least 2, 3.5 oz. portions of oily fish should be eaten weekly, but does this amount support long-term health?

Determining the correct intake of Omega-3 fatty acids depends on an individual’s age, the overall state of physical and mental health, and whether there is a history of trauma that suggests heightened inflammation. To find out the amount that is best for your unique condition, make sure to consult with your health care provider or schedule an appointment at the Kaplan Center.

Brain Boosting Properties of Resveratrol

4 Brain Boosting Properties of Resveratrol

/in , /by

What do pistachios, peanuts, blueberries, and grapes have in common? In addition to providing a tasty snack, they are all sources of resveratrol, a naturally occurring substance found in certain plants that offers a number of health benefits to the brain!

Resveratrol is a type of phytoalexin, a substance produced by plant tissues that promotes disease resistance. Medical researchers are still exploring the mechanisms by which it works but it has clearly proven its impact on reducing inflammation in the central nervous system (inflammation of this nature is a major contributor to chronic pain, depression, and neurodegenerative diseases).

Sources of resveratrol

A well-balanced diet that includes lots of fruits, vegetables, and nuts is a wonderful way to obtain Resveratrol. Other food sources include mulberries, raspberries, red wine, pomegranates, dark chocolate, and soy beans.

Bioavailability

Successful in vivo studies (involving animals or humans) are limited but show promise. One reason for their limited success is that Resveratrol has low bioavailability. Merriam-Webster defines bioavailability as “the degree and rate at which a substance is absorbed into a living system or is made available at the site of physiological activity.” In other words, before our bodies are able to reap its benefits, Resveratrol is rapidly absorbed and eliminated. Researchers continue to look for ways to enhance its bioavailability through dosage concentrations and combinations with other compounds. For example, just as piperine can improve the bioavailability of curcumin, it may also improve the bioavailability of resveratrol. A 2020 study published in The Egyptian Rheumatologist concluded that “piperine administration concurrently with resveratrol potentiated the anti-inflammatory efficacy of resveratrol in arthritic-induced rats which could be attributed to the bio-enhancing activity of piperine”.

Possible Clinical Applications of Resveratrol
  1. It has demonstrated neuroprotective qualities post-stroke, post-Traumatic Brain Injury (TBI), and/or post-spinal cord injury. A 2021 review published in Neurochemistry International, which looked at both in vivo and in vitro studies, confirmed that Resveratrol “can induce a neuroprotective state when administered acutely or prior to experimental injury to the CNS.”
  2. It can potentially lower a person’s risk of opioid dependency. A 2020 study published in World Academy of Sciences Journal found that “RES can potentiate the antinociceptive effects of morphine and reduces morphine tendency and reinstatement.” In other words, this study suggests that it’s possible that Resveratrol, when taken with morphine, can prevent the development of hyperalgesia (increased sensitization to pain) – a condition that often leads to opioid dependency. Furthermore, Resveratrol acts without compromising the morphine’s effectiveness.
  3. It can improve age-related mood and memory function. Resveratrol’s anti-aging and anti-inflammatory properties seem to protect cells in the hippocampal region of the brain from damage. This region of the brain converts short-term memory to long-term memory, and is part of the limbic system, which regulates emotion. A study published in Scientific Reports showed that middle aged, Resveratrol-treated rats had “improved learning, memory and mood function” in older age than their “vehicle” (a substance usually without therapeutic action) or control-treated counterparts.
  4. It reduces amyloid plaque formation. Amyloid plaques present as a sticky buildup that accumulates outside nerve cells or neurons, and they have been linked to Alzheimer’s disease. A 2022 study published in Free Radical Biology and Medicine, found “strong evidence for resveratrol’s neuroprotective and anti-plaque capabilities in viral-induced AD, which merits its further exploration as an AD preventive and therapeutic candidate.”

 

Supplementing with Resveratrol

Resveratrol supplements are available in pure form or combined with other compounds. Dosages are typically somewhere between 5mgs and 5gms, depending on the individual’s medical condition.

* If you are considering taking a supplement, make sure to talk with your physician about possible interactions with other medicines.

In sum, Resveratrol is a powerful anti-oxidant with a demonstrated potential to nurture and even heal the brain. With many delightful sources available in food, supplementing with Resveratrol can ensure that our bodies get even more of this wonderful gift from nature!

Addressing the Fear of Cognitive Decline & How to Be Proactive

/in , , /by

Alzheimer’s disease, the most common form of dementia, is the sixth leading cause of death in the U.S. For most people, the subject of Alzheimer’s brings fear and trepidation. Why? Because the thought of deteriorating brain function and memory loss is frightening. Unfortunately, current medical treatments are inadequate, dealing only with its end result.

Alzheimer’s is characterized by the destruction of synapses in the neurons, the nerve cells in the brain, by amyloid plaques. In addition, “tangles” form in the cells leading to loss of brain function. This leads to progressive loss of memory and behavioral problems like aggression, hallucinations, and delusions, as well as deterioration of activities of daily living. This is heartbreaking for patients and their families. And, despite years of ongoing research, there are still many unanswered questions about what causes Alzheimer’s disease.

Let’s explore some of the known risks associated with dementia and learn how to lower those risks.

Type 3 Diabetes

You may not have heard the term “type 3 diabetes” as another name for Alzheimer’s Dementia. Type 2 diabetes and prediabetes, also called insulin resistance, are both strongly linked to the development of Alzheimer’s dementia. This could actually be good news because it means this is a preventable risk factor.

Why has the term Type 3 diabetes been coined?  Let’s start by discussing sugar, which in large quantities is a poison. The body is not designed to handle more than 15-20 grams per day, yet a soda has at least 40 grams and the average American consumes 82 grams per day.

Excess sugar causes an outpouring of insulin from the pancreas and over time causes the cells in the body – including the brain – to become resistant to insulin. This leads to chronically elevated blood sugar which causes Advanced Glycation End products or AGEs to be produced. These AGEs then attack the eyes, kidneys, peripheral nerves, and the brain!

Environmental factors

Heavy metals, such as lead in pollution and mercury in dental amalgams, and large fish, like tuna, swordfish, and shark increase the risk of dementia. In the 1800s the term “mad as a hatter” came about because hat makers were using a form of mercury to make fur hats and it destroyed brain cells.

Living or working in a water-damaged building leads to the growth of toxic mold, which poisons the nervous system.

Studies also show that living near major highways is a risk factor for Alzheimer’s.

Other causes of dementia include:

  • Recurrent traumatic brain injury (concussions)
  • Infections like Lyme disease and syphilis
  • Excess alcohol and drugs
  • Prolonged general anesthesia
  • Sleep apnea
  • There are several genes that predispose to Alzheimer’s such as the ApoE4. However, just because we have a gene does not mean it will be expressed. Every time we eat, exercise, sleep, meditate, communicate, create something, play, learn, and love, we are turning genes on and off.

The good news is the brain can actually grow and change in a positive way, even as we get older.

Be proactive in reducing your risk of dementia with these strategies:

Lifestyle strategies can promote neurogenesis (new brain cells) and neuroplasticity (changes in the brain and its pathways). These strategies involve a substance called BDNF or brain-derived neurotrophic factor, which promotes brain cell growth and connectivity as demonstrated on MRI scans. In fact, the hippocampus, which is involved in emotional memory, gets larger the more BDNF is available. A large part of the lifestyle strategy involves modifying the diet to lower unhealthful carbs and increase healthful fats thus lowering the risk of diabetes.

  1. Reduce (non-vegetable) carbohydrate consumption.
    Sugars/artificial sweeteners and grains can cause inflammation of the lining of the digestive tract, or “leaky gut”. An inflamed gut causes an inflamed brain and reduces the size of the hippocampus. Functional testing looking at stool, urine, and breath can determine if your gut is leaky. Replace nutrients lost from a leaky gut or poor diets like B12, folate, B6, magnesium, and iron.
  2. Increase healthy fat consumption.
    Increase your omega-3 fat intake and reduce the consumption of damaging omega-6 fats (like processed vegetable oils) in order to balance your omega-3 to omega-6 ratio. Omega-3 from fish sources shows a lower risk of cognitive impairment.
  3. Add prebiotics & probiotics to your diet.
    Prebiotic fiber nurtures gut bacteria and the hippocampus. Probiotic supplementation, which enhances the healthy bacteria in the gut, decreases the inflammatory marker, C-reactive protein, increases the antioxidant  glutathione, and improves mental status as measured by the Mini Mental Status Exam
  4. Improve your sleep habits.
    Work on getting at least 7-8 hours of solid sleep. If sleep is poor, rule out sleep apnea. A 2020 study published in the journal Sleep confirms that people who have obstructive sleep apnea – or intermittent interruptions in breathing – in their middle ages are more likely to develop Alzheimer’s Disease. If you’re not sure if you have sleep apnea, but you find yourself exhausted during the day, take this short quiz as the first step towards diagnosis.
  5. Exercise!
    Physical activity produces biochemical changes, increasing BDNF, that strengthen and renew not only your body but also your brain – particularly the hippocampus, the area associated with memory and learning. This is especially important for carriers of the ApoE4 gene. A good exercise regimen includes aerobic and resistance training at least 3-4 times per week for 30-45 minutes.
  6. Try Niagen+ IV Therapy to boost NAD+ levels.
    Sirtuins, which are NAD+-dependent enzymes, have shown to benefit brain health by acting on amyloid plaques, repairing DNA, lowering inflammation, and promoting neuronal function, which in turn can prevent or delay the onset of mild cognitive decline. Click here to learn how Niagen+ IVs help boost NAD+ levels.
  7. Go Keto.
    The ketogenic diet. is linked to an increase in BNDF, which causes the hippocampus to get bigger (better memory). This involves cutting down on carbohydrates which reduces insulin resistance (diabetes) and increasing good fats like avocado, olive oil, MCT (medium-chain triglycerides found in coconut oil), and intermittent fasting 12-14 hours between dinner and breakfast so that the body breaks down fats and produces ketones. Note: The Ketogenic diet is not for everyone, ask your physician before starting any specialized diet.
  8. Eliminate toxins.
    Consider getting tested for heavy metal and toxic mold exposure and work with your doctor to eliminate them.
  9. Check your hormone levels.
    Balance hormones, such as thyroid, cortisol, sex hormones, and Vitamin D (which is actually a hormone).
  10. Find out whether you are insulin resistant.
    Get a HgA1C test and a fasting insulin test. Eliminating the risk of Type 2 diabetes (insulin resistance) can lower the risk of Alzheimer’s dementia (Type-3 Diabetes).
  11. Remember to take time to slow down, be mindful (meditation and yoga) spend time with loved ones, and take time to laugh and have fun. This is medicine for our minds.
