The coronavirus presents many uncertainties, and none of us can completely eliminate our risk of getting COVID-19. But one thing we can do is eat as healthily as possible.

If we do catch COVID-19, our immune system is responsible for fighting it. Research shows improving nutrition helps support optimal immune function.

Micronutrients essential to fight infection include vitamins A, B, C, D, and E, and the minerals iron, selenium, and zinc.

Here’s what we know about how these nutrients support our immune system and the foods we can eat to get them.

Vitamin A


Vitamin A maintains the structure of the cells in the skin, respiratory tract and gut. It maintains the structure of the cells in the skin, respiratory tract and gut. This forms a barrier and is your body’s first line of defense. If fighting infection was like a football game, vitamin A would be your forward line.

We also need vitamin A to help make antibodies which neutralize the pathogens that cause infection. This is like assigning more of your team to target an opposition player who has the ball, to prevent them scoring.

Vitamin A is found in oily fish, egg yolks, cheese, tofu, nuts, seeds, whole grains and legumes.

Further, vegetables contain beta-carotene, which your body can convert into vitamin A. Beta-carotene is found in leafy green vegetables and yellow and orange vegetables like pumpkin and carrots.

B vitamins

B vitamins, particularly B6, B9 and B12, contribute to your body’s first response once it has recognised a pathogen.

They do this by influencing the production and activity of “natural killer” cells. Natural killer cells work by causing infected cells to “implode”, a process called apoptosis.

At a football match, this role would be like security guards intercepting wayward spectators trying to run onto the field and disrupt play.

B6 is found in cereals, legumes, green leafy vegetables, fruit, nuts, fish, chicken and meat.

B9 (folate) is abundant in green leafy vegetables, legumes, nuts and seeds and is added to commercial bread-making flour.

B12 (cyanocobalamin) is found in animal products, including eggs, meat and dairy, and also in fortified soy milk (check the nutrition information panel).

3. Vitamins C and E

When your body is fighting an infection, it experiences what’s called oxidative stress. Oxidative stress leads to the production of free radicals which can pierce cell walls, causing the contents to leak into tissues and exacerbating inflammation.

Vitamin C and vitamin E help protect cells from oxidative stress.

Vitamin C also helps clean up this cellular mess by producing specialised cells to mount an immune response, including neutrophils, lymphocytes and phagocytes.

So the role of vitamin C here is a bit like cleaning up the football ground after the game.Good sources of vitamin C include oranges, lemons, limes, berries, kiwifruit, broccoli, tomatoes and capsicum.

Vitamin E is found in nuts, green leafy vegetables and vegetables oils.

Vitamin D

Some immune cells need vitamin D to help destroy pathogens that cause infection.

Although sun exposure allows the body to produce vitamin D, food sources including eggs, fish and some milks and margarine brands may be fortified with Vitamin D (meaning extra has been added).Most people need just a few minutes outdoors most days.

People with vitamin D deficiency may need supplements. A review of 25 studies found vitamin D supplements can help protect against acute respiratory infections, particularly among people who are deficient.

Iron, zinc, selenium

We need iron, zinc and selenium for immune cell growth, among other functions.

Iron helps kill pathogens by increasing the number of free radicals that can destroy them. It also regulates enzyme reactions essential for immune cells to recognise and target pathogens.

Whole grain foods contain a variety of important nutrients. Shutterstock

Zinc helps maintain the integrity of the skin and mucous membranes. Zinc and selenium also act as an antioxidant, helping mop up some of the damage caused by oxidative stress.

Iron is found in meat, chicken and fish. Vegetarian sources include legumes, whole grains and iron-fortified breakfast cereals.

Zinc is found in oysters and other seafood, meat, chicken, dried beans and nuts.Nuts (especially Brazil nuts), meat, cereals and mushrooms are good food sources of selenium.

Putting it all together

It’s true some supermarkets are out of certain products at the moment. But as much as possible, focus on eating a variety of foods within each of the basic food groups to boost your intake of vitamins and minerals.

While vitamin and mineral supplements are not recommended for the general population, there are some exceptions.

Pregnant women, some people with chronic health conditions, and people with conditions that mean they can’t eat properly or are on very restrictive diets, may need specific supplements. Talk to your doctor, Accredited Practising Dietitian or pharmacist.

And beyond diet, there are other measures you can take to stay as healthy as possible in the face of coronavirus.

Stop smoking to improve your lung’s ability to fight infection, perform moderate intensity exercise like brisk walking, get enough sleep, practise social distancing and wash your hands with soap regularly.

County Hospitals Receive 300 iPads for Patients to See Family

Published

on

LOS ANGELES – 300 iPads have been donated to Los Angeles County hospitals to facilitate patient-family communication during the COVID-19 pandemic. The gift is through a partnership with the Annenberg Foundation, Brilliant Corners, and the Los Angeles County Center for Strategic Partnerships.

“The engagement of loved ones during hospitalization has been shown to improve clinical outcomes,” said DHS Director, Dr. Christina Ghaly. “Clinical staff identified a role for virtual visiting through technology in order to facilitate this family involvement. The generous donations by the Annenberg Foundation and MobileDemand will help support this critical element of our patients’ care.” 

Due to the COVID-19 pandemic, patient visitation by family and loved ones is limited at facilities in order to prevent exposure and the spread of disease. While there are some exceptions, such as the birth of a child or death of a patient, visitation is not permitted for the vast majority of patients and not allowed at all for COVID-19 patients. 

The donation provides 300 iPads to ensure patients and their families are able to connect, despite restrictions in access to the hospital. A second donation, by MobileDemand, provides rugged, protective healthcare iPad cases to protect against damage and loss. The rugged case also has an adjustable easel attached, providing effortless viewing for patients who are too weak to hold a tablet. Additionally, it frees health care staff from having to hold the device for patients.

“This is a wonderful example of how philanthropic organizations, nonprofits, government, and businesses can collaborate and meet an immediate need in our community,” said Wallis Annenberg, Chairman, President and CEO of the Annenberg Foundation. “Being able to offer an opportunity for comfort and connection to those suffering and to alleviate some of the stress from our frontline caregivers is of utmost importance.”

While social distancing has been successful in flattening the curve of the COVID-19 surge in Los Angeles County, it is anticipated that it will continue for several months. With this gift, physicians and nurses will be able to place an iPad in the room of COVID and other critically-ill patients for the duration of the admission and reduce potential exposure and use of personal protective equipment going in and out of the room. Having a stationary iPad helps relieve medical staff who would otherwise have to hold the phone for a patient or search for the person’s personal phone. It also will allow patients who do not have a personal mobile device to communicate and “visit” with their family.

The Los Angeles County Department of Health Services (DHS) is the second largest municipal health system in the nation. Through its integrated system of 26 health centers and four hospitals – LAC+USC Medical Center, Harbor-UCLA Medical Center, Olive View-UCLA Medical Center, and Rancho Los Amigos National Rehabilitation Center – and expanded network of community partner clinics, DHS annually provides direct care for 600,000 unique patients, employs over 22,000 staff, and has an annual budget of over $6 billion.

Processions to Cedars Will Salute Healthcare Workers on National Nurses Day

Published

on

The coronavirus (COVID-19) outbreak is putting a strain on essential workers such as first responders and healthcare workers who are on the frontlines in the effort to care for coronavirus patients so the City of West Hollywood is setting out to recognize them in a special way on May 6.

National Nurses Day is a day of recognition to celebrate and honor the contributions that nurses have made and continue to make in our communities and throughout the nation. National Nurses Day is celebrated annually on May 6, which marks the beginning of National Nurses Week, a week-long celebration to raise awareness of the value of nursing and educate the public on the role nurses play in meeting the healthcare needs of Americans. National Nurses Week concludes on May 12, the birthday of Florence Nightingale, or as she was more commonly known, “The Lady of the Lamp” and founder of modern nursing.

The West Hollywood Sheriff’s Station of the Los Angeles County Sheriff’s Department is coordinating two motorcades to honor healthcare workers on Wednesday, May 6, 2020, which is nationally recognized as National Nurses Day. The processions will begin at 9:45 a.m. and at 7:15 p.m. on Santa Monica Boulevard at La Cienega Boulevard and the motorcades will head west and then travel southbound on N. San Vicente Boulevard passing multiple medical center locations in West Hollywood en route to a destination outside the emergency room entrance of Cedars-Sinai Medical Center on Gracie Allen Drive. First responders will briefly stop, exit their vehicles and applaud healthcare workers while wearing face coverings and practicing appropriate social distancing.

“Our nurses and healthcare workers are nothing short of heroes,” said City of West Hollywood Mayor Pro Tempore Lindsey P. Horvath. “The coronavirus pandemic has reminded us just how critical their work is to our everyday health and safety. This National Nurses Day means so much more to all of us — the City of West Hollywood and our LA County Sheriff’s West Hollywood Station and LA County Fire Stations; the City of Beverly Hills and Beverly Hills Police and Fire; the City of Los Angeles and LAPD and LAFD; the California Highway Patrol, and more — and we will honor these heroes in a special way for the care that they provide, which often goes unseen and unrecognized, in carrying us through this crisis.”

“As the worldwide response to the novel coronavirus (COVID-19) continues, the critical importance of nurses in our society has been brought sharply into focus,” said City of West Hollywood Councilmember John Heilman. “More often than not, when a coronavirus patient ends up in a hospital, it is the nurses at the frontlines who are responsible for their care and treatment, putting themselves at risk in the process. We can’t say ‘thank you’ strongly enough.”

The City of West Hollywood encourages residents and community members to participate during this day of celebration while still adhering to LA County Safer At Home Orders and social distancing requirements. Suggested forms of participation include amplifying posts on social media channels, making yard or window signs and banners, participating in a coordinated daily applause or shout out for nurses and healthcare workers, and donating to organizations that are addressing the emerging needs of nurses and healthcare workers during the coronavirus (COVID-19) health pandemic.

According to the American Nursing Association, nursing is the nation’s largest healthcare profession, with more than four million registered nurses in the United States. Registered nurses comprise one of the largest segments of the U.S. workforce and are the primary providers of hospital patient care, delivering most of the nation’s long-term care. In nursing, where workers are on the front lines of patient interactions, women make up more than 85 percent of the workforce. This year, with the onset of coronavirus, nurses have stepped up and shown the incredible impact they have on our healthcare system. It is more important than ever that we recognize National Nurses Day and celebrate the significance of nurses every day.

Texas & California Wet Markets Show Full Extent of Vile Conditions

Texas & California Wet Markets Show Full Extent of Vile Conditions

(TMZ) — It’s becoming more clear by the day that wet markets are NOT just a China problem — it’s an American problem too … just take a look at these latest clips from Texas and California.

TMZ has gotten a hold of even more graphic videos of two different live animal shops in TX and CA — where people pick out the animal, have it slaughtered on the spot and then sold to them right then and there — and you see the mixed-in livestock runs the gamut.

There are pigs in pens, goats and sheep hoarded together … and, of course, as we’ve seen in New York and elsewhere — chicken and rabbits cooped up in cages — all in the same area within earshot of each other, and all getting butchered.

Ya got pigs hanging from hooks out in the open, chicken beaks, feathers and guts all over the floor and in an exposed trash can — this while customers (including kids) come in and browse the freezer for whatever cuts of meat they want. It’s downright dirty and gross.

As we’ve been told by the experts, these one-stop-shop slaughterhouses/storefronts can be breeding grounds for disease — including new viruses, like COVID-19, which supposedly got started at a wet market in China.

We already know of lawmakers in Cali and New York working to get these things shut down, but it’s pretty apparent there needs to be federal legislation rolled out to address this. Can’t call the kettle black when we’re swimming in the freakin’ pot.
