Food to Boost the Immune System During COVID-19 Lockdown

Food to Boost the Immune System During COVID-19 Lockdown

The recent COVID-19 (Corona Virus SARS-CoV-2) has shook the world since 2019. We here in South Africa are new victims of the virus and are currently in lockdown for 3 weeks. During this time there is still much that can be done to promote our immune systems. This maximizes our chances of fighting off infections of any sort that could be worsened with a positive diagnosis of COVID-19. There are particular ways of handling food and its preparation to minimize the risk of transmitting the virus. There are also certain organic foods we as the green community can grow and incorporate more into the food we eat.

Wash your hands before and after touching anything. This is important after going outside, touching your face, coughing, blowing your nose or sneezing. This includes washing with clean water and soap for at least 20 seconds. The only alternative to washing your hands is using hand sanitizer over 60 % alcohol.

Apply this sanitary approach to the kitchen and home in general. Keep all areas clean and disinfected. A special mention for keeping your working surfaces clean as well as washing all fresh produce.
If you have stocked up on ready-to-eat foods for a long period, you may need to remove the meat components from these that may spoil . Refrigerate all your leftovers within 2 hours to keep from contamination and spoiling.


Vitamin D is imperative to kill pathogens causing infection but is the most vulnerable vitamin during lockdown. This is due to the fact that a big source of vitamin D is exposure to sunlight. Make sure to spend extra time outside or sitting in the sun if your living arrangements allow it. If not, increase the amount of fortified soy, almond or rice milk; mushrooms; fortified orange juice; fortified tofu and fortified cereals in your food choice during lockdown. Vitamin D deficiency linked to autoimmune issues. This is when your body’s immune system attacks itself. This is a crucial issue in the mechanism of COVID-19 so this is a big one to watch out for.

Vitamin C has always been a big priority around the “flu season” so it is no shock to find it in the list. Vitamin C is linked to white blood cells integrity and formation. These are the soldiers of the immune system. Boost the body’s natural defense force by planting and eating more Citrus fruits (limes, lemons ,oranges, naartjies) as well as berries, kiwi fruits, tomatoes, chillies and peppers and broccoli. Try hit your RDA (recommended daily allowance) as you urinate out excess vitamin C.

Vitamin E works with vitamin C to fight the effects of oxidative stress. This state occurs when the body is fighting infection and runs the risk of furthering inflammation which is a key feature of COVID-19. Boost the number of leafy green vegetables such as spinach and lettuce, nuts and vegetable oils in your food selection and garden during this lockdown.

Vitamin A is crucial in the immune system fighting COVID-19 as it protects the cellular structure of the respiratory system and the stomach. These are 2 target areas of the COVID-19 virus. Vitamin A is also crucial in the formation of antibodies to fight off the virus after infection. Leafy green vegetables, carrots, pumpkin, tofu, legumes, nuts and seeds as well as whole grain foods are each an incredible source of Vitamin A. Include these in your food choices during lockdown.

2 minerals in particular are key in the fight against COVID-19 during lockdown. These are iron and zinc. Iron helps to fight infection and is found in legumes, spinach, lentils, tofu, amaranth, fortified cereals and potatoes. Zinc is important in the respiratory airways as well as in helping the immune system after oxidative stress. Ingredients high in zinc to include in your lockdown food choices are chickpeas, seeds including chia and pumpkin seeds, wholemeal bread, quinoa and cashew nuts.

The microbes in the stomach and the microbiome in large is imperative in a healthy body. This is the environment inside your gut. The more diverse the conditions in a person’s gut, the healthier that person is. They are better armed to beat infections attacking the body during COVID-19 infection. There is research linking the microbes in the gut with the regulation of inflammation and the immune system in general. Eating a diversity of nutrient rich food and controlling your body’s PH will aid with a healthy immune system.
Plants high in fibre such as whole grains, nuts and seeds, berries, fruits and vegetables. Cut out processed junk foods and replace it with healthy fats such as coconut oil and olive oil. Natural yoghurt and yeasty drinks are amazing for supporting your gut microbes.

Obviously one cannot manifest a garden full of fresh produce especially during lockdown. Get supplements of the above from your pharmacy which is still available during this lockdown. Keep an eye on your energy levels and other vitamin deficiency-related symptoms. Research them online and boost your intake of the vitamin you are deficient in.

Sugar has negative affect on your immune system functioning. So be very careful in this lockdown with the amount of sugar in your daily teas and coffees which are very tempting when confined to the house.
Processed foods and junk foods deplete your body’s health. They compromise the immune system’s ability to respond to infection and stress. Avoid these in your food choices.
Food high in fat as well as red meat are quick to fry up when home all day but are very dangerous for your long-term health. They are bad for your cholesterol and blood system.

Handling the Vervet Monkey

Handling the Vervet Monkey

Vervet monkey, baby Vervet monkey

Our Durban Vervet monkey is a special creature. Cunning and smart yet desperate and running out of living space, they have often been seen as a nuisance by Durban residents. Some feel sorry for them and feed them whilst others see them as a pest and attack them. Both are poor handling techniques. Vervet monkeys, however, are not classified as “vermin” and are, in fact, protected by National and provincial conservation legislation thus making the harming of these creatures a punishable offence.

Such offenses arise as a result of the urbanisation of Durban as it has grown over the years. Houses, offices and other buildings replace the monkey habitats making it harder for them to live and feed. So, they resort to cunning tactics of breaking into homes and ransacking kitchens and gardens to get food, destroying valuable plants in your garden. So what handling techniques and tips do we have to offer?

⦁ Keep food items out of reach of the monkeys, locked in secure cupboards. Out of sight, out of mind applies here too!
⦁ Keep windows and doors closed when you are not home. You can secure mesh to the windows to allow circulation and security.
⦁ Dogs are great monkey repellants but train them to never maul or try harm them severely. You want the dogs to bark and chase them away from afar.
⦁ Leftover dog or cat food must be moved out of reach of the monkeys. Also try change up your routine for feeding the birds so that this does not become a predictable routine.
⦁ If you have small children, ensure they do not eat food outside. Vervets have a habit of trying to snatch food from women and children. Children are less capable of anticipating this danger so teach them to eat indoors and not take leftovers outside.
⦁ Use rubber snakes in accessible and visible areas as monkeys avoid snakes. Water guns and hose pipes can be used to squirt the monkeys but not soak them as they can suffer in the colder nights. Change its location or attach it to a nylon string to not allow the snake to be perceived as dead.
⦁ Sensor sirens work too when they are set off by movement within the proximity. Tins tied by string at intervals performs a similar function.
⦁ Never take on a Vervet head on. They are not aggressive unless threatened or cornered. Stay facing them and wave a towel or stick above your head if they try stand their ground. Do not attack them though. Rather have a man do this as they sometimes challenge women. A small piece of hose pipe with holes being swung above your head makes a noise that scares them too.
⦁ Spray your crops with a chilli, tobacco or curry solution to repel them from your garden plants. Use netting and transparent boxes over your plants to prevent them being torn up.
⦁ Secure lids on your rubbish bins and you can spray Jeyes drain fluid around it to deter the monkeys.
⦁ You can lubricate cables or telephone wires or cover them with a movable piece of PVC to deter monkeys from accessing your house from these locations.
⦁ DO NOT use pellet guns or cattys as these harm monkeys. A broken bone or cut to a monkey can be life or death in their lives. It may only seem like a superficial wound to us, but their lives suffer more than we can anticipate.
⦁ DO NOT feed them or allow them any association with food and your house or living area.

While they may present themselves as a nuisance, it is a result of our civilization that has pushed them to these extents. BeeGreen is working on projects that will keep the monkeys healthy but far away from residents- training them somewhat to leave resident’s homes alone. We aim to optimise monkey handling techniques and tips. There is a balance between drawing firm boundaries with them but treating them humanely.

Spring Conditions in Durban

We all wait with baited breath for the Spring to return to our country. Yet, this is also a time as dangerous as it is beneficial for the garden. Durban sees many volatile swings in weather over a short space of time especially over the months spanning September- December.


Howling winds, scorching afternoons and heavy showers are a danger for the newly planted garden. The winds dry out the plants and increase water loss. New saplings are especially vulnerable yet placing a coffee jar with the container covering the sapling helps in extremely windy patches. Watering plants that have been exposed to extremely high temperatures and winds also helps to reduce damage to the plant although this should always be done when coolest- in the morning or the evening after a hot windy day.


Finally, storms have been getting more intense in Durban as seen by the effects of phenomena like Hurricane Sifiso in 2017. These threaten to flood soil and kill your plants through root rot. Address this by draining flooded pots or placing sensitive plants like new saplings under cover or, merely placing an umbrella over them- just ensure the umbrella can not be blown around and further damage your plants.


If there is any other concerns during this time of Spring, get hold of your eco-community leaders on and we will always help where we can. We even help rehabilitate damaged plants. You can also sign up to our community where you can be notified ahead of time of any extreme weather.


Overall,  keep an eye on the weather forecasts, time your watering schedule carefully and look to protect vulnerable plants during the Spring season to see full abundance during this time of growth and new life.
