Fasting for three days can regenerate entire immune system, study finds

Fasting for as little as three days can regenerate the entire immune system, even in the elderly, scientists have found in a breakthrough described as "remarkable".

Although fasting diets have been criticised by nutritionists for being unhealthy, new research suggests starving the body kick-starts stem cells into producing new white blood cells, which fight off infection.

Scientists at the University of Southern California say the discovery could be particularly beneficial for people suffering from damaged immune systems, such as cancer patients on chemotherapy.

It could also help the elderly whose immune system becomes less effective as they age, making it harder for them to fight off even common diseases.

The researchers say fasting "flips a regenerative switch" which prompts stem cells to create brand new white blood cells, essentially regenerating the entire immune system.

"It gives the 'OK' for stem cells to go ahead and begin proliferating and rebuild the entire system," said Prof Valter Longo, Professor of Gerontology and the Biological Sciences at the University of California.

"And the good news is that the body got rid of the parts of the system that might be damaged or old, the inefficient parts, during the fasting.

“Now, if you start with a system heavily damaged by chemotherapy or ageing, fasting cycles can generate, literally, a new immune system."

Prolonged fasting forces the body to use stores of glucose and fat but also breaks down a significant portion of white blood cells.

During each cycle of fasting, this depletion of white blood cells induces changes that trigger stem cell-based regeneration of new immune system cells.

In trials humans were asked to regularly fast for between two and four days over a six-month period.

Scientists found that prolonged fasting also reduced the enzyme PKA, which is linked to ageing and a hormone which increases cancer risk and tumour growth.

"We could not predict that prolonged fasting would have such a remarkable effect in promoting stem cell-based regeneration of the hematopoietic system," added Prof Longo.

"When you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged," Dr Longo said.

"What we started noticing in both our human work and animal work is that the white blood cell count goes down with prolonged fasting. Then when you re-feed, the blood cells come back. So we started thinking, well, where does it come from?"

Fasting for 72 hours also protected cancer patients against the toxic impact of chemotherapy.

"While chemotherapy saves lives, it causes significant collateral damage to the immune system. The results of this study suggest that fasting may mitigate some of the harmful effects of chemotherapy," said co-author Tanya Dorff, assistant professor of clinical medicine at the USC Norris Comprehensive Cancer Center and Hospital.

"More clinical studies are needed, and any such dietary intervention should be undertaken only under the guidance of a physician.”

"We are investigating the possibility that these effects are applicable to many different systems and organs, not just the immune system," added Prof Longo.

However, some British experts were sceptical of the research.

Dr Graham Rook, emeritus professor of immunology at University College London, said the study sounded "improbable".

Chris Mason, Professor of Regenerative Medicine at UCL, said: “There is some interesting data here. It sees that fasting reduces the number and size of cells and then re-feeding at 72 hours saw a rebound.

“That could be potentially useful because that is not such a long time that it would be terribly harmful to someone with cancer.

“But I think the most sensible way forward would be to synthesize this effect with drugs. I am not sure fasting is the best idea. People are better eating on a regular basis.”

Dr Longo added: “There is no evidence at all that fasting would be dangerous while there is strong evidence that it is beneficial.

“I have received emails from hundreds of cancer patients who have combined chemo with fasting, many with the assistance of the oncologists.

“Thus far the great majority have reported doing very well and only a few have reported some side effects including fainting and a temporary increase in liver markers. Clearly we need to finish the clinical trials, but it looks very promising

BACON WRAPPED CREAM CHEESE STUFFED CHICKEN BREAST

An easy, but elegant main dish! The chicken is moist, the flavor superb and the bacon a perfect wrapping!
Author: Adapted by Catherine Daugherty
Recipe type: Main Dish
Cuisine: American
Serves: 4 large servings
Ingredients
1 lb. Boneless skinless chicken breast cut into 4 – 4 ounce pieces
4 tablespoons cream cheese
¼ cup Pepperjack cheese, shredded
2 tablespoons green onion, chopped
4 to 8 pieces of bacon
Instructions
Cut chicken into 4 equal size pieces. Pound breast so it is about ¼" thick.
Mix together softened cream cheese, chopped green onions and shredded pepperjack cheese. Put ¼ of this mixture into the middle of each piece of chicken.
Starting at the long side, roll chicken breast up, keeping the cheese mixture to the middle.
Wrap 1 to 2 slices of bacon around the chicken breast, secure with toothpick, if needed.
Place on baking sheet and back for 30 minutes at 375 degrees F.
Broil topside for about 5 minutes to fully brown and crisp bacon. Turn each breast over and broil for another 3 minutes or so to crisp up the bottom side.
Serve immediately.
Notes
* One piece of bacon wrapped around each breast is enough. But 2 pieces of bacon for each breast fully wraps the chicken and is outstanding as well.

* 1 lb. of chicken usually equals one large chicken breast cut in half. Cut each half in half again and you will have four 4 ounce pieces. 

* This recipe is very adaptable to being basted with your favorite grilling sauce, marinade, chili sauce, or sweet and sour sauce during baking.

If You Eat Garlic And Honey On An Empty Stomach For 7 Days, Here’s What Happens To Your Body

When it comes to cooking, garlic is one of my favourite ingredients. And it’s such a versatile ingredient that it can be used in almost any savoury dish! Roasted with some proteins, stir-fried in some vegetables, blended into a creamy pasta sauce…. the list goes on and on. Personally, I absolutely love the flavour and aroma of garlic so when a recipe calls for two cloves of garlic, I’ll somehow justify to myself that I really should be putting in five or six. And the best part is that I don’t feel too guilty about it because garlic is healthy!

Garlic can be used to help lower cholesterol levels and blood pressure, and prevent cancer, heart attacks, coronary heart disease, and atherosclerosis. This superfood can also be used to help treat the common cold, the flu, bug bites, fungal infections, and traveller’s diarrhoea. Garlic is great for strengthening your immune system while eliminating toxins, leading many people to consume it after chemotherapy.
But while I love cooked garlic, garlic in its raw form is apparently how you’re going to get the best results. This is because heating garlic has been shown to reduce its anticancer properties and inactivate a key enzyme called alliinase. What you’ll want to do to maximise the health benefits of garlic is to crush it up raw, releasing the enzymes that will break down into good organosulfur compounds, and then eat it on an empty stomach. But raw garlic is incredibly pungent, so try this…

Take 2-3 garlic cloves, chop up and crush them, and mix it with a tablespoon of honey (also healthy with anti-bacterial properties!). If you can consume it this way on a regular basis, it can go a long way in boosting your immune system!
