COVID-19 strategy: Build immunity in your kitchen!


It’s easy to feel helpless while we wait for an effective treatment for COVID-19 or any other infection, but look at it this way: better health through home cooking has never been more convenient!  The kitchen is the best place to work on strengthening the immune system, and it just so happens that most of us have some extra time right now.  We also all have some adjustments we can make to our food and activity choices to boost our immunity and lower our risk factors, and preparing our own meals from scratch is one of the most powerful single adjustments we can make.  Choose from a wide range of whole foods, culture a healthy intestinal tract (“gut microbiome”), avoid refined carbohydrates and sweet drinks, get daily exercise, and schedule 7-9 hours of sleep at night: these steps all help our immune systems beat back bad bugs.  You’ll find a prescription for improving immunity and reducing inflammation on pages 22-23 of Good Food, Great Medicine (4th edition).  By the way, type 2 diabetes and high blood pressure are both associated with weakened immunity, and the steps to boost immunity are the same ones you would take to reverse these two conditions: simply treating them with medications does little to improve immunity. For a 14-step plan to reverse type 2 diabetes and high blood pressure, turn to the Risk Reduction Action Plan on pages 90-110. The best time to start is now!

My recommendation:
We’ve talked about what to do, so now let’s talk about putting it into action.  Grab your copy of Good Food, Great Medicine and turn to the section called Practical Eating (pages 111-150): it’s full of tips on shopping for ingredients and equipment, menu planning, meal suggestions, and cooking.

COVID-19 strategy: Fitness is hygiene for your immune system


Some patients have told me that they can’t work out because their gym is closed.  Pre-COVID-19, this can’t-work-out syndrome was blamed on other factors (time, weather, bad knees, and so on) but it simply represents a fundamental misunderstanding of exercise.

The fact is, exercise is another form of hygiene; a self-care activity to improve immunity, reduce inflammation, help prevent unnecessary disease, and improve our quality of life.  We brush our teeth twice a day, so we can take two minutes to exercise twice a day!  Like any important act of hygiene, exercise can be done in any scenario.  Don’t get me wrong – gyms are great: lots of extra equipment, often a fun atmosphere, and good social interaction.  However, what about when the gym is closed? 

My recommendation:
Do whatever it takes to be able to exercise under any circumstance.  Love lifting weights?  Buy some – or use something you already have, like a couple of milk jugs filled with water.  Can’t live without the rowing machine at the gym?  Get one and put it in your living room – or achieve the same results with simple resistance bands.  Favor minimalism?  Get a jump rope, medicine ball, and pull-up bar, throw in some jumping jacks, go for a brisk walk outside. . . there are virtually endless home work-out options if we just get creative.  (For more ideas, see Let’s Move More! on pages 70-74 in Good Food, Great Medicine, 4th edition.)  Exercise is too important to be neglected at a time like this.  It’s another form of hygiene: let’s treat it like one!

COVID-19: Another reason to reverse your diabetes and high blood pressure


As the COVID-19 pandemic continues to unfold, people tend to focus on their acute risk factors, behaviors, and interactions to avoid exposure.  This make good sense from an individual and public health perspective, but we need to be equally aggressive in pursuing habits and lifestyle changes that will improve not only our overall immunity and strengthen our natural defenses against COVID-19, but also improve our quality of life and longevity.  This approach is especially needed for those with type 1 and type 2 diabetes and high blood pressure.

Many view diabetes as an independent disease of the endocrine system that only encompasses blood sugar and vascular concerns; however, the immune system implications are profound.  Unfortunately, this may be particularly true in the case of coronavirus susceptibility.  In a recent article in Lancet Respiratory Medicine, [1] the authors hypothesized that a specific enzyme elevated in people with diabetes or high blood pressure, as well as those on ACE inhibitor blood pressure drugs, may increase their susceptibility to coronavirus.  Here is the relevant quote for those interested in the technical details:

“Human pathogenic coronaviruses (severe acute respiratory syndrome coronavirus [SARS-CoV] and SARSCoV-2) bind to their target cells through angiotensin-converting enzyme 2 (ACE2), which is expressed by epithelial cells of the lung, intestine, kidney, and blood vessels.  The expression of ACE2 is substantially increased in patients with type 1 or type 2 diabetes, who are treated with ACE inhibitors and angiotensin II type-I receptor blockers (ARBs)… These data suggest that ACE2 expression is increased in diabetes and treatment with ACE inhibitors and ARBs increases ACE2 expression. Consequently, the increased expression of ACE2 would facilitate infection with COVID-19.”

This isn’t to suggest that you should stop taking ACE inhibitors: these medications have benefits that are carefully considered by your doctor and sometimes necessary depending on your disease process.  It DOES, however, remind us of the fact that diabetes, and probably high blood pressure, are major risk factors for impaired immunity, and every effort should be taken to vigorously pursue lifestyle measures to reverse type II diabetes and high blood pressure. 

This is a challenging time for our nation and our local communities.  We need to be in a position to help care for our most vulnerable, and that starts with taking good care of ourselves.  As always, Dr. Hassell and I are available (largely via telehealth right now) to advise you in these efforts and answer any questions you may have.

My recommendation:
For a comprehensive plan to reverse type 2 diabetes and high blood pressure, the Risk Reduction Action Plan on pages 90-108 of Good Food, Great Medicine (4th edition) is a good place to start.  You can also download the following evidence-based lifestyle handouts at goodfoodgreatmedicine.com/resources/resources.htm

Are you concerned about the Coronavirus (Covid-19)?

If you are, it’s not surprising, considering the relentless play-by-play news coverage.  It is too early to know what level of concern is justified, but the next couple of weeks will probably tell us.  Flu viruses typically wane rapidly in March, so normal seasonal factors could throttle this outbreak before it gets a foothold here in North America.  In the meantime, there are simple steps we can all take to build up our immunity, not just to protect us from a flu virus, but also from most other preventable disease.  These steps will even reduce your risk of premature cancers, heart disease and stroke, type 2 diabetes and pre-diabetes, dementia, and depression.


Our recommendation:
As well as the usual flu-fighting precautions (hand washing, coughing protocol, and so forth), these nine steps will help develop and maintain a robust and fighting-fit immune system.

1. Eat at home!  Prepare your own food from scratch where possible.  Processed foods are associated with worse health outcomes, while homemade whole foods are associated with better immunity.  Include vegetables or whole fruit, protein, and healthy fat with every meal and snack.  (See Good Food, Great Medicine 4th edition for ideas: pages 134–150.)

2. Minimize sugars, sweet drinks, fruit juice, and refined grains. These high starch/high carbohydrate foods contribute to abnormal sugar metabolism, including type 2 diabetes and prediabetes.  Type 2 diabetes, in turn, is associated with depressed immunity and vulnerability to severe complications from influenza and a host of other maladies.

3. Eat high-quality protein.  Your immune system runs on protein, so make sure you include beans, whole grains, fish (especially oil rich fish such as salmon, herring, sardines and tuna), poultry, eggs, cultured dairy (yogurt, kefir and cheese), and unprocessed meat (beef, lamb, and pork).

4. Culture a healthy microbiome, a diverse range of good bugs in your intestines (gut).  Your microbiome is dependent on eating a wide range of whole foods to "feed" your gut, of which whole grains may be the most important.  Eat cultured foods such as plain yogurt and kefir, and traditional fermented foods like fresh sauerkraut -- but remember that most whole foods are also loaded with probiotics.  Apple cider vinegar (1–2 tablespoons per day in salad dressing or in a glass of water or sparkling water) also helps the microbiome.  We recommend that you do not take probiotic supplements: they can actually have a harmful effect by narrowing the diversity of the gut bugs.

5. Exercise! The contribution of exercise to immunity and overall health is poorly appreciated. Need antioxidants?  Exercise!  Need anti-inflammatories? Exercise! Want to cut your risk of influenza? Exercise! Want to reverse your type 2 diabetes or type 2 diabetes? Exercise!  Many exercise recommendations exist: include something two or three times a day, even if only for 5–10 minutes each time, upper and lower body, and get a bit short of breath and sweaty. Skip rope, climb stairs, go for a brisk walk, toss a medicine ball, use a rowing machine. . . find something that works for you.

6. Sleep is an essential nutrient our bodies can’t store, and is restorative to every aspect of our immune systems.  Schedule 7 – 9 hours nightly, especially if you’re concerned about getting sick.
 

7. Heat, as in regular deep hot baths (for 15–30 minutes daily) or saunas (5–10 minutes a few times per week) seem to improve cardiovascular risk, mood, blood sugar, and help with weight management.  The important factor may be the transient increase in core body temperature activating the immune system.

8. Sunlight seems to boost the immune system, too.  (Admittedly, here in Portland it is not a dependable source for much of the year; for other sources see our handout Calcium, Vitamin D, and Osteoporosis.)  We recommend a few minutes (5-15) of direct, non-burning midday sunlight on sunny days, with as many square inches of skin exposed as possible, without sunscreen.  This helps produce vitamin D and probably many other metabolic benefits.

9. Finally, consider cutting back on screen time: it not only makes it harder to do the previous 8 steps, but it also exposes us to an unhealthy level of news about the Coronavirus!  

What if you do get the flu, or symptoms that you suspect could be the coronavirus? 
It would probably be wise to contact your physician, especially if you are in a high risk group due to your health history, known exposure, or recent travel to a high-risk area.  Meanwhile, read our Cold, Flu, and Sinusitis handout for treatment tips, useful information about natural remedies and pharmaceutical options – and even recipes!

Live longer, avoid cancer, and lose weight: research shows that making your own food may be your most important decision

Living longer and feeling better is often a matter of which food we eat when we’re hungry – and it looks like we’d be all be better off if we stop choosing commercially-processed food.  This includes those convenient ready-to-eat protein bars, heat-and-eat meals, and food from restaurants or grocery store delis.  Multiple studies show commercially processed food to be associated with increased weight gain [1], a shorter life [2], and more cancer [3].  In one of the most recent studies [1], participants were randomized to either a diet of unprocessed food or a diet of highly-processed food: both diets were matched for calories, sugar, fat, fiber, and other major nutrients.  Those eating the highly processed foods gained weight over the period of the study, while those eating unprocessed foods lost weight; although they were offered the same amount of food, they apparently simply ate less.  There appears to be many reasons why processed foods cause more harm (see pages 59–61 of Good Food, Great Medicine, 4th edition), including chemical alterations during processing, additives, calorie density, and less appetite suppression.  The fact that those eating less processed foods were also more likely to be at lower risk of common diseases is a bonus worth considering!
 
My recommendation:
For optimal health, one of the best decisions we can make for ourselves and our family is to prepare our food from scratch as much as possible.  It takes some extra time, but the rewards are unbeatable.  Get together with family and friends and make home cooking a part of your life.  Bring a lunch to work.  Keep snacks simple and homemade, and put together a repertoire of easy dinners.  Teach children how to help in the kitchen when they’re young and cook when they’re older.  There are lots of meal planning ideas, recipes, and snack suggestions in Good Food, Great Medicine, pages 134–146.  Call our office at 503.291.1777 to sign up for a disease reversal class or schedule an appointment for a one-on-one medical consultation (goodfoodgreatmedicine.com).

Good bugs for a better mood

Want a better mood – with less help from drugs?  Try increasing the good bugs in your GI tract!  The mechanism for benefit may be the ability of your gut microbes to produce butyrate, a short chain fatty acid with a wide range of metabolic effects, including strengthening the epithelial defense barrier [1], a layer of cells that line the gut to resist invaders like toxins and bad bugs.  In fact, it is increasingly evident that a healthy gut microbiome is also associated with a multitude of other health benefits such as better weight management, less cancer, diabetes, heart disease, and more.  Now that should help improve your mood!    

My recommendation:
There are many non-drug options for treating depression and anxiety, including targeted diet therapy, fitness, weight management, light exposure, and heat therapy; this study adds powerful support for eating more probiotic foods such as plain kefir and yogurt (meaning unsweetened, with milk and active cultures as the only ingredients) as well as foods like salt-cured sauerkraut and kimchi for a healthier gut microbiome and mood.  Although there is a subgroup that does very well on medications, be aware that the lifestyle prescription on pages 23-24 of Good Food, Great Medicine (4th edition) is arguably more powerful medicine.  For more on how and why to choose probiotic foods, see page 49.

Joint steroid injection? Think twice…

There are ongoing concerns that steroid injections for painful knee osteoarthritis [1,2] may have the negative effect of accelerating joint breakdown while having no benefit – including for pain control – compared to placebo injections.  This is in addition to data showing that even short-term steroids (as well as other anti-inflammatory medications) have significant potential for harm to overall health.

My recommendation:
This is an area of legitimate debate; however, given both the uncertainty regarding the benefit and the potential harm, I strongly recommend that patients exhaust all other options before having steroid injections.  The alternative is a plan that includes meticulous attention to diet, weight, blood sugar management, appropriate exercise, and topical or oral pain medications.  There are some nutritional supplements that may help, and targeted physical therapy can make an enormous difference.  Occasionally I use lidocaine injections without steroids and see excellent results.

Keep the most important goals in mind: less pain and improved function in the short term, and avoiding further joint breakdown or joint replacement in the long run.  Make sure you have all options in view.  (See my 5/1/2017 blog post on corticosteroids for more information about short-term oral steroids.)
