Trans fats and hypothyroidism: Trans fats shrink the brain, increase dementia risk

A recent study found a diet high in trans fats shrinks the brain and increases the risk of dementia, making them a poor choice for people with Hashimoto's and hypothyroidism. The brain depends on proper thyroid function, and a brain-healthy diet is paramount for people with Hasimoto's and hypothyroidism.

Trans fats are found in fast foods, processed foods, margarine, shortening, and more. They can be identified in a list of ingredients as hydrogenated or partially hydrogenated oil.

Hypothyroidism diet: High in vitamins, omega 3s

On the other hand, study participants who ate diets high in vitamins B, C, D, and E and omega 3 fatty acids were found to have larger, healthier brains than their junk-food eating counterparts. These nutrients are found in a diet high in vegetables, fruits, fish, and raw nuts and seeds.

A brain-healthy diet will also tame autoimmune flare-ups and inflammation associated with Hashimoto's and hypothyroidism.

Even small amounts of trans fats damaging

Although a few studies in the past have examined the link between brain health and trans fats, this study by Oregon Health and Science University in Portland was the first to measure blood levels of trans fats in relation to brain volume using MRI brain scans.

The most sobering observation was that blood levels of trans fat levels were not that high, a testament to the damage they cause even in small amounts.

Researchers suggest that trans fats in the diet replace healthy fats in the brain's cell membranes, which affects the ability of the brain to function properly.

Brain is made of mostly fat

Cell membranes communicate with other cells and determine what is allowed to enter and exit the cell. Fatty acids make up a significant portion of cell membranes, brain tissue, and myelin sheaths, which protect neurons that communicate with one another. In fact, about 60 percent of the brain is made up of fat, coming from fats in the diet.

Trans fats replace good fats in brain

When trans fats become part of the cells and nerve sheaths they replace vital brain fats, such as DHA, an essential omega-3 fatty acid. As a result, cellular communication suffers, the cells degenerate, brain volume shrinks, and memory and cognition suffer.

Trans fats restrict blood flow to brain

Trans fats also contribute to the clogging of veins and arteries, which inhibits blood flow to the brain. Constricting blood flow to the brain robs the brain of oxygen and vital nutrients, another factor that degenerates, or shrinks, the brain and affects function.

The good news is that a diet high in vitamins B, C, D, and E, and omega 3 fatty acids protects the brain from shrinkage and decline. The study subjects who ate a diet abundant in these nutrients consistently scored better on mental performance tests and showed less brain shrinkage.

Eating to protect brain health with Hashimoto's hypothyroidism

Trans fats are closer to plastic than food, significantly impacting brain health, and it’s best to strictly avoid them.

Instead, aim for a brain-friendly diet that includes leafy green vegetables, seafood, eggs, olive oil, nuts, avocadoes, colorful fruits, nuts, and meats.

Also, eliminating all sweets and sodas, minimizing starchy foods (grains, potatoes, legumes, etc.), and eliminating foods to which you are intolerant (gluten and dairy, for example) will reduce inflammation, another factor that shrinks the brain and steals memory.

Studies show a strong link between Hashimoto's hypothyroidism and gluten intolerance, making a strict gluten-free diet important for managing thyroid health.

Other food intolerances are common for those with Hashimoto's hypothyroidism. An allergy-elimination diet is a good way to ferret out which foods may be causing inflammation.

Is a chemical sensitivity worsening your Hashimoto's hypothyroidism?

You've probably heard of food intolerances to gluten, dairy, eggs, or other foods. But chemical intolerances, or sensitivities, have become increasingly common, as well. A person with a chemical sensitivity has an immune reaction to chemicals and heavy metals in air pollution, pesticides, plastics, adhesives, household cleaners, cosmetics, perfumes, and more.

When exposed to these chemicals, the sensitive person may react with a variety of different symptoms, including migraines, fatigue, inflammation, brain fog, memory loss, vertigo, sore throat, respiratory or sinus problems, or a skin rash.

For the person with autoimmune Hashimoto's hypothyroidism, a chemical sensitivity creates a chronic assault on the immune system, making it difficult to manage this autoimmune thyroid condition.

Why doesn't everyone have a chemical sensitivity?

Although we now live in a world of thousands of toxic chemicals, some people react to chemicals and some don't. In fact, lab testing may reveal the person who doesn't react actually carries a heavier toxic burden than the person who reacts very easily. Why?

The answer lies in how well the person's immune system handles exposures to chemicals and pollutants in our environment. Several factors can cause a chemical intolerance:

• The immune system reacts to certain chemicals or heavy metals as allergens due to an immune imbalance.
• An individual has lost the ability to detoxify chemicals from everyday exposure.
• An individual's natural antioxidant status is deficient, increasingly one's vulnerability to toxicity from chemicals.
• A breakdown of immune barriers—gut, lungs, skin, and blood-brain barrier—increases the body's vulnerability to toxins.

In other words, it's not necessarily small exposures to toxic chemicals or heavy metals that make one sick (even though they are not good for us), but instead the body's inability to handle environmental toxins.

How chelation can worsen Hashimoto's hypothyroidism

A common method of treating a chemical sensitivity or other chronic condition is chelation. Chelation is a detoxification therapy that removes heavy metals from the body.

However, for the person whose immune system is reacting to chemicals and heavy metals, chelation can actually make things worse. By using chelation to liberate chemicals and heavy metals from tissue and into the bloodstream, the chemically sensitive person may react with even more symptoms and more tissue damage.

For the person with Hashimoto's hypothyroidism, this means a flare-up of the condition and worsening symptoms.

Chelation should only be considered if the immune barriers are in tact (i.e., no leaky gut, or leaky blood-brain barrier, which would allow chelated toxins into the brain), the immune system is balanced, and detoxification functions are working normally.

How to prevent or alleviate a chemical sensitivity

These days, it is difficult to isolate ourselves from pollutants, chemicals, and heavy metals. There is very little testing of new chemicals that enter our environment, and it is extremely difficult to require manufacturers to ban chemicals. Instead, you can focus on using toxin- and scent-free cleaners and personal care products, eating organic, whole foods, and consuming plenty of fibrous, antioxidant-rich vegetables and filtered water to help cleanse your system.

Beyond that, we have more advanced clinical strategies to help alleviate a chemical sensitivity. These include supporting the activity of glutathione, the body's most powerful antioxidant, repairing the immune barriers—gut, lung, and blood-brain—with nutritional support, balancing the immune system, and restoring the body's natural ability to detoxify.

Holiday sugar hangover cure?

The tin of peppermint bark is empty, the pies polished off, and the Yule log cake reduced to crumbs.

Left in their wake, however, is the sugar hangover, that annual holiday tradition that may include an upset stomach, headache, lethargy, brain fog, skin problems, join pain, mood swings, allergy symptoms, and a heap of regret.

How to recover from a sugar hangover

While alcohol hangover cures are a folklore staple, you can take solid steps to recover from your sugar hangover:

• Quit eating sweets. Those holiday treats have sent your blood sugar levels skyrocketing and plummeting repeatedly, taxing the immune system, the brain, hormone balance, and every other system in the body.

  To recover, put blood sugar levels on an even keel by eating protein every two to three hours, eating a good breakfast, and avoiding starchy foods, desserts, and sweet drinks (soda, sweet coffee drinks) that spike blood sugar. Instead focus on quality proteins, leafy vegetables, and good sources of fat (olive oil, avocado, coconut oil, salmon, etc.)

• Drink plenty of water. This is also the most popular alcohol hangover cure for a reason. Staying hydrated with clean filtered water will help flush your body of toxins and aid in recovery.

• Support your liver. Processing all those sweets burdens your liver. Help your liver flush these toxins with such liver detox nutrients as milk thistle, dandelion, N-acetyl L-cysteine, beet root, panax ginseng, and more. Contact my office for more advice on liver detoxification.

• Restore your gut. Sweets cause inflammation, promote overgrowth of harmful yeast and bacteria, and irritate the gastric lining. You can restore gut health by avoiding sweets and other starchy foods, temporarily adopting a strict detox diet that eliminates common immune triggers (i.e., gluten), and by eating cultured and fermented foods.

• Move your body. A brisk walk, a swim, yoga, or some other gentle exercise will get your lymphatic system pumping and blood flowing to help flush toxins and rejuvenate cells. You may want to avoid extremely vigorous exercise until hangover symptoms subside so as not to further promote inflammation.

Why not go for a New Year's detox?

These are some basics to help you recover from a sugar hangover and get you back on the wellness path. In fact, all of these tips will help you recover from an alcohol hangover, too. For more advanced strategies and to get started on a detox plan for the New Year, contact my office.

Depression linked with bad digestion

Question

I went to see my natural medicine practitioner for depression and she wants to work on my digestive health. I don’t get the connection.

Answer

Many people would be surprised to learn how greatly gut health affects brain health. A poor diet, inflamed gut, and intestinal permeability definitely can promote depression.

Depression a not-so-obvious symptom of poor digestion

Sometimes digestion issues are obvious; they cause gas, bloating, heartburn, indigestion, diarrhea, constipation, or abdominal pain. For others the main symptom is not so obvious—depression. An unhealthy diet and compromised gut health can promote depression in several ways.

Poor nutrition

When one eats a junk food diet laden with processed foods, trans fats, sugars, and artificial chemicals, the brain suffers. The brain needs healthy fats, high-quality protein, abundant vitamins and minerals, and a diet low in starchy foods and sugars.

Gluten

Gluten is directly linked to depression in some. It causes gut inflammation, which can lead to inflammation in areas of the brain that regulate mood. Some people digest gluten into gluteomorphin, an opioid similar to heroin or morphine that can cause depression (not to mention constipation). Gluten can also cause autoimmune attacks in the brain with symptoms of depression.


Dairy or other foods may also cause depression, depending on sensitivity.

Leaky gut

Leaky gut happens when the lining of the intestines becomes overly permeable. This allows undigested foods, bacteria, and other pathogens into the bloodstream, creating inflammation throughout the body. Inflammation in the brain may cause depression.


Inflammation in the gut also inhibits absorption of nutrients necessary for good brain function. An example of such a nutrient is tryptophan, an amino acid found in proteins. The brain synthesizes tryptophan into serotonin, a brain chemical that promotes feelings of well-being and joy.

Always consider gut health

Depression is a complex, multi-faceted condition that can have its roots in various causes. However the role of diet and digestive health should always be included in a functional approach to depression.
