How long does it take to regenerate donated blood?

How long it takes to regenerated the blood after blood donation depends on the individual.  And it also depends on what source you are citing.

According to American Red Cross, …

“The plasma from your donation is replaced within about 24 hours. Red cells need about four to six weeks for complete replacement. That’s why at least eight weeks are required between whole blood donations.”

According to Anemia.org

“It takes a couple of days to replace plasma, the watery substance of your blood. Making red blood cells take a little longer, but a healthy donor can replace those that were donated within two weeks.” 

Typical amount of blood taken when donating blood in the United States is 500 milli-Liters (about 1 pint and roughly 1 pound, or roughly 10% of your blood assuming typical amount of 5 liters of blood in body).

And it typically take 10 minutes for that amount to come out.  But the prelim check and paper work can take more time.  Plus after the donation, you need to wait at the facility for another 15 minutes to see if you are okay and don’t faint.

To avoid faintness, drink a lot of water or fruit juice before and after the donation — at least two glasses before the donation.  But best to drink well within the 24 hours prior to donation. This helps keep the blood pressure up.  Blood pressure drop is the primary cause of fainting.

When blood pressure drops, the body boosts it back up by having the adrenal glands secrete more aldosterone.  Those with adrenal fatigue may have problems producing aldosterone and hence may be more prone to fainting during donation.

Also have a hearty meal before the donation (within three hours of donation). This keeps the blood sugar level up.   And a hearty meal afterwards as well.  Don’t do strenuous exercise for another 24 hours.

Books about Real Stories of People Who Went to Heaven and Returned

The following are non-fiction books accounting of near-death experience — or some would argue a more accurate description is death and then a return to life. Non-fiction means that the author is writing what he or she perceive as the truth.

Some Drinks — Are They Healthy or Not?

No, not alcoholic drinks, I just mean beverages.   This article is about some thoughts on a few beverages.

Most of us know to not drink soda anymore due to harmful effects of sugar and artificial sweeteners and sometimes even high fructose corn syrup. But what do we drink instead? Let’s look at some alternatives which are definitely healthier.

We’ll look at water, green tea, coffee, vegetable juice, coconut water, kefir, and kombucha. But are they really healthy? Unfortunately, I can not answer this question because it all depends on the individual and the situation and how much. They all have their pros and cons.

Water – sure it is healthy, except…

The only exception is water, which in nearly all cases is healthy — unless it is contaminated with chloride, fluoride, or other toxins.  But you thought fluoride in water is good for the teeth?  Not really, and here is why.

Water is not healthy is when you drink insane amounts of it which dilutes all your electrolytes from your circulatory system. There have been reports that a person died in a water-drinking contest.[reference]

Six researchers did a study to determine what was the best healthy beverage to drink. It turns out to be water, followed by tea and coffee (both drunk plain that is).[6]

Article on Harvard School of Public Health says …

“Water should be the beverage you turn to most of the time”

Water has zero sugar, zero calories, and zero saturated fat. We all need water and cannot live without it. It is a basic element of life.

One report states that woman needs 11 cups of fluid a day and men needs 15 cups. Note that this amount includes the fluids from all foods and other beverages. The best gauge is to let your body dictate how much water you need. Definitely drink when you’re thirsty. But try to drink so that you do not get thirsty. By the time you feel thirst, you are already a bit dehydrated.

However, drinking plain water can be a bit boring. And for some people drinking plain water means going to the bathroom more frequently because it just passes right through.

So let’s look at other healthy beverages.

Green Tea

Probably the second most healthy beverage after water.  See the health benefits of green tea.

Coffee

Is coffee healthy or not?

Vegetable Juice

Is Vegetable Juice Healthy?

Coconut Juice

Yes, coconut juice is healthy, but watch the sugar.

Kefir

Kefir has good probiotics.  But not for someone who is sensitive to dairy, casein, or lactose. Learn more.

Kombucha

Kombucha is an effervescent fermented tea drink. It is fermented with a combination of healthy bacteria and yeast.  So perhaps those with yeast overgrowth may need to be cautious.

Because of the fermentation processes, some natural alcohol may be formed. But it is often less than less than 0.5% ethanol.  Because of the fermentation process, kombacha contain live probiotics that can be of benefit to health. Other healthy byproducts may include B vitamins, amino acids, organic acids, and enzymes.

However, many doubt the health claims of kombucha and there are incidences of complications in some individuals. There are cases contamination due to home-brewing. If you are going to try kombucha, try the commercially produced brands such as GT’s or Synergy first. If you look at the food label on the bottle, you will see that it is usually quite low on sugar.

Dr. Andrew Weil writes that he knows of no health benefits and that he is …

“concerned about the possibility of contamination in home-brewed kombucha. Some batches contain aspergillus, a toxin-producing fungus. This would be a significant risk for individuals with compromised immune systems, such as those with AIDS or in chemotherapy for cancer. There have been reports in the medical literature of adverse reactions, including nausea, vomiting and headaches, in people drinking more than four ounces of kombucha tea daily.”

Article on RobbWolf.com writes …

“If you are a child, are pregnant, have a compromised immune system, or have kidney disease you may want to talk with your doctor or caution your intake of kombucha.”

MayoClinic.com article writes …

“In short, there isn’t good evidence that kombucha tea delivers on its health claims. At the same time, several cases of harm have been reported. Therefore, the prudent approach is to avoid kombucha tea until more definitive information is available.”

The media such as MSNBC and the New York Times have written about kombucha as well.

In general, probiotic beverages are healthy. This may include kefir and kombucha. Another probiotic drink is KeVita that was mentioned by as being great by Mira and Jayson Calton in the episode “Rich Food, Poor Food” on Underground Wellness radio podcast.

Dr. Axe has good things to say about Kombucha…

 

Beverages to Avoid

Avoid soft drinks and other sugary drinks that contains lots of sugar. This includes any sport drink and vitamin water that contains a lot of sugar. Excessive amounts sugar is one factor that contributes to metabolic syndrome, diabetes, and obesity.

Dr. Jonny Bowden says that soda is one of the two worst foods one can eat. The other is french fries.

Vitamin water is basically water with a little bit of vitamin added. You would most likely get more vitamin by juicing real vegetables. Or take a multi-vitamin pill with your water.

If you think the zero-calories beverages are good for you, think again. Many zero-calories beverages contains artificial sweeteners. Although it is true that artificial sweeteners do not raise blood sugar, some such as aspartame can damage brain cells through excitotoxicity.

Masala chai

I haven’t tried this one, but Mark Sisson says that masala chai is healthy due to its cinnamon, ginger, cardamon, fennel, and clove. But again, easy on the sugar.

He also mention “choffy” as healthy which is ground up roasted cacoa beans steeped in hot water.

Creamy tumeric tea is nice too.

Is Green Tea Healthy?

The book The Chemistry of Calmsays …

“Make pure water your main beverage. … If you like green tea, you can drink it throughout the day.” [page 69-70]

Green tea is our second most healthy beverage — second to water.

Unsweetened green tea can contain zero sugar. Its health benefit comes from its antioxidant capabilities. Green tea contains catechins such as epigallocatechin-3-gallate (EGCG) which inhibits cancer growth. Green tea is also good for the heart since it helps dilate blood vessels.[reference]

In his talk about nutrition and cancer, Dr. Donald Abrams says he drinks 4 cups of green tea each day. See video above.

Although green tea has relatively low caffeine as compared to coffee. If you are concerned about caffeine, don’t drink green tea before bed so as to not affect your sleep.

Direct-to-Consumer Lab Tests

In the past few years, there has been a spawning of various direct to consumer lab testing. These are places online where you can order your own medical tests, go to a local blood draw location (such as LabCorp or Quest Diagnostic), and get your results online. No doctor visits nor referral are needed. All the standard blood tests like cholesterol, glucose, vitamin D, B12, etc are available.

These are great for people who do not have insurance or have a high deductible insurance. And they just want to check their basic health status every once in a while without needing a doctor’s visit. It is sometimes difficult to get a doctor’s appointment without insurance. Because the first thing they ask is what insurance you have.

For those who do have insurance, there might be times when you want to get a test done, but your doctor says that it is not warranted. You can now get your own test done.

Also there are certain tests that you might want to run more frequently without having to always make a doctor’s visit. We all know that doctors are quite busy and have a full queue of patients. An example is a diabetic who wants to get an glycated hemoglobin A1C test done every three months to check to see if diet and exercise is having an effect.

With the Internet as a research tool, many consumers are savvy as to what tests to run and what the results means. For those individuals, they can save the time and expense with direct-to-consumer lab testing.

However, there are others consumers who would be better off seeing a physician in the traditional setting. These do-it-yourself testing is not for everyone.

Of course, there are certain medical conditions where a physician is definitely recommended for everyone.

What Others are Saying about Direct to Consumer Lab Testing

Here is what the media is saying about direct-to-consumer lab testing …

Direct-to-Consumer Lab Testing sites

Here are some direct-to-consumer lab testing sites…

  • DirectLabs.com — Chris Kresser mentions the use of this lab on his site.
  • PrivateMDLabs.com — Jimmy Moore mentions this one on his site.
  • TrueHealthLabs.com — They have Cyrex gluten sensitivity and autoimmune antibody screening tests.
  • WellnessFx.com — They say “You Can Only Improve What You Measure”. They have an health platform that track your biomarker results.

Books on Mind-Body Medicine and Nutrition

The symptoms of anxiety, irritability, and depression often are related. That is because they can different manifestations of the same underlying imbalance. It is not all in the head. The body and nutrition can affect these moods, as can various effects on neurotransmitter and gut flora balance. Some say they symptoms are related to inflammation of the brain.

Some books to give more insights are …

The Mood Cure starts off Chapter 1 by saying …

“If you’re often feeling depressed, anxious, or stressed, you’re not alone. We’re in a bad-mood epidemic, a hundred times more likely to have significant mood problems than people born a hundred years ago.”

Unstuck: Your Guide to the Seven-Stage Journey Out of Depression is by James S. Gordon M.D. who says that “Depression is not a disease”, but rather that …

“stress and the action of stress hormones are more likely causes of depression and of observed changes in neurotransmitter levels.”


The Chemistry of Calm: A Powerful, Drug-Free Plan to Quiet Your Fears and Overcome Your Anxiety talks more about the biochemistry of mood.
