Health and Wellness Throughout the Season


pills

The trifecta of COVID, cold and flu season is already upon us.  Rather than avoiding contact with others, you have another defense besides vaccines for COVID and the flu.  Vaccines are beneficial but your immune system can also fight off infections or reduce their severity if you treat it well.  Here are a few tips for improving your immune function.  Now go out and enjoy holiday gatherings with your family and friends, while using your best judgment for keeping yourself and others healthy. 

  • Get Vaccinated - Get fully vaccinated for COVID-19 and the flu.  This may prevent having the flu and COVID-19 at the same time.  Even if you get COVID-19 or the flu you symptoms won't be as severe, vaccines may save your life.

  • Eat a Nutrient-Dense Diet - Eat a diet rich in antioxidant nutrients such as beta-carotene, vitamins C, and minerals, selenium, and zinc which help to bolster the immune system.  Fresh fruits and vegetables, especially colorful ones are rich in antioxidants.  Start slowly and work up to 5 servings a day of fruits and vegetables.  It’s easier than you think.

  • Reduce Bad Carbs - Try to stay away from refined sugar, concentrated sugars, and refined carbohydrates in both food and drinks.  High blood sugar levels can reduce the ability of white blood cells to fight infections.

  • Stay Hydrated - Drink plenty of water, staying hydrated will keep your mucous membranes moist and prevent bacteria and viruses from entering your system.  Water also helps to flush your system of toxins and circulate important nutrients.

  • Improve Beverage Choices - Reduce alcoholic beverages, excess alcohol can dehydrate your body and depress the activity of white blood cells.  Drink alcoholic beverages in moderation or not at all.  If having alcoholic beverages make sure you're drinking water too.

  • Wash Hands - Wash hands often with warm soapy water especially before prepping meals and before eating.  So simple, but yet we can spread so many germs around this way.

  • Exercise - Lose excess weight, research suggests an increased number of infections occurring in people with obesity.  Those with high blood cholesterol and lipid levels have fewer white blood cells and a slower response to fighting infection.  Being underweight can also increase susceptibility to infections.  Try to maintain a healthy weight.

  • Sleep Well - Sleep deprivation interferes with immune function.  A study found that those who slept less than 5 hours per night were more likely to catch a cold than those who slept 7 hours per night.  The body functions optimally with least 7 to 8 hours of quality sleep per night.

  • Manage Your Microbiome - Probiotics are live microorganisms that provide many health benefits.  They are known as beneficial bacteria that live in your gastrointestinal (GI) system.  Probiotics can bolster your immune system and shorten the duration of colds.  Food sources of probiotics are yogurt, kefir and the fermented foods such as sauerkraut and kim chee.  Look for foods that contain "live cultures."  Probiotic supplements are also an option but can be difficult to choose one appropriate for your needs.  Consult a nutritionist for the best option.

  • Breathe Fresh Air - Get outside for some fresh air, especially if you've been indoors for long periods at a time breathing recirculated air.  Open your windows on occasion to remove any accumulated pollutants and bring some fresh air into the house.

  • Get Some Sunshine/Vitamin D - Get outside for some sunshine so your body can make some vitamin D.  A vitamin D supplement may be necessary if you live in the Pacific Northwest or have a lack of sunshine during this time of year.  There's evidence that your vitamin D levels can make a difference in the severity of COVID-19 symptoms.  Those who were deficient in vitamin D have more severe symptoms and lower survival rates.  An additional study, showed those who had sufficient vitamin D levels had a 54% reduced risk of getting infected with COVID-19.  Contact us to gain access our dispensary for professional grade multivitamins, minerals and vitamin D.

  • Stay Home & Relax - If the risk of contracting an illness and/or you risk exposing your loved ones to illness, plan to recover, relax and stay home.  Avoid spreading the flu, a cold or COVID if you've been exposed or think that you may be ill.

Confusing Food Expiration Labels

While shopping for packaged foods do you find the labels that say "sell by", "best by", "use by",... confusing?  Is the food actually expired and unsafe to eat?  You're not alone, many consumers feel the same way.  The "sell by" date is actually for the retailer to ensure that they rotate their stock, however it doesn't mean it's unsafe to eat.  This can lead to excess food waste if a food is discarded when it can safely be eaten.  With the cost of food and the current state of food insecurity, we should have a better way to reduce food waste with improved or standardized labeling.  Currently the federal government does regulate food date labeling.  Something to consider next time you're trying to decipher to whether your yogurt should be eaten or thrown out.
