Whats Best For Boosting Your Immune System Sleep Superfoods Exercise Or Supplements
How do your body’s natural defences work against COVID-19 and the flu? Experts comment on whether sleeping, hydrating and exercising more really help and whether you should spend money on supplements.
If theres one thing that probably wont change in the new year during these pandemic times, its our desire for healthier practices such as getting more sleep or devoting more time to self-care.
Topping many peoples lists is something weve been trying to do a lot these past couple of years: Strengthening our immune system against COVID-19.
And most recently, against a globally growing phenomenon: Flurona, when you get infected with both the influenza virus and COVID-19 coronavirus, either simultaneously or back to back.
But first, what is the immune system about? The bodys natural defence doesnt just consist of one organ that does all the work, according to Dr Leong Hoe Nam, an infectious diseases physician at Rophi Clinic, Mount Elizabeth Novena Hospital. It is, in fact, a complex network consisting of white blood cells, antibodies, spleen, bone marrow and thymus, he said.
Then, there are the complement system and the lymphatic system , said Melanie Anthonysamy, the nutrition team lead at HealthifyMe.
She added that there are other lines of defence as well. These include the lungs , digestive tract , skin and other bodily fluids .

DOES EATING MORE SUPERFOODS HELP?
Vitamin C And Pregnant Women And Nursing Mothers
One thing to double check with your health care provider about is how much vitamin from any sort of supplement you should consume when pregnant or nursing. I have gotten different answers on this question. The most conservative response is probably given by Medline Plus
They say, Pregnancy and breast-feeding: Vitamin C is LIKELY SAFE for pregnant or breast-feeding women when taken in the recommended amount of 120 mg per day. Taking too much vitamin C during pregnancy can cause problems for the newborn baby.
Two dieticians answer that question here, a summery being that eating vitamin C rich food and taking a multi-vitamin will give you plenty of vitamin C , and the second opinion being that you shouldnt take over 2,000 MG of added vitamin C per day.
You can also get helpful charts for general info on recommended amounts of vitamin C from WebMD, where they also point out that, A substantial number of Americans may have low intake levels of vitamin C due to the inadequate intake of fruits and vegetables.
The point is this vitamin C is an important vitamin, but you can over do it, especially if you are pregnant or nursing. Many midwives recommend the higher amount , so there is a wide range of advice in how much to take when pregnant is optimal.
For the rest of us, it makes sense to me to get our vitamin C from food as much as possible which is why I love this recipe!
Take Your Supplement After Exercise

Possibility Of Cardiovascular Disease

However, this was observed only in a single study and is not established firmly yet.10

Too Much Vitamin C May Cause Digestive Symptoms
The most common side effect of high vitamin C intake is digestive distress.
In general, these side effects do not occur from eating foods that contain vitamin C, but rather from taking the vitamin in supplement form.
Youre most likely to experience digestive symptoms if you consume more than 2,000 mg at once. Thus, a tolerable upper limit of 2,000 mg per day has been established (
Ingesting more than 2,000 mg of vitamin C per day may lead to gastrointestinal upset, including symptoms like diarrhea and nausea.
Vitamin C is known to enhance iron absorption.
It can bind to non-heme iron, which is found in plant foods. Non-heme iron is not absorbed by your body as efficiently as heme iron, the type of iron found in animal products .
Vitamin C binds with non-heme iron, making it much easier for your body to absorb. This is an important function, especially for individuals who get most of their iron from plant-based foods .
One study in adults found that iron absorption increased by 67% when they took 100 mg of vitamin C with a meal .
However, individuals with conditions that increase the risk of iron accumulation in the body, such as hemochromatosis, should be cautious with vitamin C supplements.
Under these circumstances, taking vitamin C in excess may lead to iron overload, which can cause serious damage to your heart, liver, pancreas, thyroid, and central nervous system .
Zinc: Sources And Dosing
One of the most common questions among those taking zinc to boost their immune system is “Can you take too much zinc?” After all, it is used in over 100 chemical interactions that occur daily within the body . Therefore, some assume that more zinc would be beneficial to the body. However, excessive amounts of this mineral can be dangerous and experts recommend monitoring foods containing zinc in your diet while also consuming a zinc supplement.
When taken in appropriate amounts, zinc is used by the body to improve taste perception, DNA synthesis, encourage growth, support healing, and boost immune function and reproductive health. Clearly, these are all important bodily functions, which is why consuming foods containing zinc on a daily basis is vital.
Most national health organizations list 40mg of zinc as the upper limit for daily consumption, so it is key to understand the amount of zinc that is in your vitamins vs. how much zinc you consume through your diet.

Make Sure To Store Your Vitamin C Products Correctly
In topical skin-care products, vitamin C is sensitive to light and air. When exposed to these factors, it becomes oxidized to dehydroascorbic acid, which is less stable and less efficacious, Dr. Hogan explains. So these products should be stored in opaque containers that are either air-restrictive or air-tight, she says, like an airless pump rather than a tub or dropper bottle that requires being opened all the way.
Luckily, many vitamin C products already come in opaque containers for this exact reason, Dr. Lamb says.

Side Effects Of Vitamin C
Having too much Vitamin C is unlikely to be overly harmful to us, but massive doses can cause diarrhea, nausea, heartburn, stomach cramps and headaches. You need to find what balance is right for your body.
Another side effect that many are not aware of is the effect Vitamin C can have on our teeth. Understanding that this vitamin is actually an acid makes it easier for us to come to recognise the potential dangers involved in having those refreshing pieces of lemon in our water.
We think that by eating oranges and sipping lemon water all day will help improve our immunity and help ward off colds and flus. Now we know that it certainly does help with this, but it can also erode our precious tooth enamel.
The acid in the citrus fruit is just as bad for our teeth, if not worse, than the popular soft drinks that we are all so cautious of.
When patients come into the clinic and tell us they have been experiencing some sensitivity in their teeth, we ask about their diet. Have you been drinking lots of soft drink or juice?
When we examine their teeth, we can often easily see the effects that this acid has had. Sadly, sometimes the enamel has been washed away completely. We then recommend that they use a sensitive toothpaste to help alleviate the symptoms.
We also need to be aware of the same corrosive effects of chewing Vitamin C tablets. These tablets stick to your teeth and can then remain on your teeth for longer periods of time.

Too Much Copper In Your Multivitamin Can Cause Behavior Changes
Chances are when you hear the word copper, pennies and jewelry are more likely to come to mind than supplements. But copper a mineral essential for your bones, ligaments, and joints is commonly found in multivitamins. While normal copper blood levels range from 70 to 140 micrograms per deciliter , anything higher than that can lead to copper toxicity .
As Healthline explained, the side effects of too much copper can be physical, mental, and behavioral. Beyond headaches, fever, and black stool, copper poisoning can also cause jaundice yellowing of the skin and the white part of the eye. Someone with excessive copper levels may experience sudden mood changes, and become irritable, depressed, or overexcited. And in the long term, this type of poisoning can lead to heart and liver failure, brain damage, and death.
In addition to supplements, substantial amounts of copper can be found in such foods as quinoa, dark chocolate, soybeans, crabs, liver, and asparagus . Also, if your home uses copper pipes, you may have high levels of copper in your water supply. Pipe corrosion, industrial waste, and runoff from nearby farms can also increase the copper toxicity of your water.
