Who should take NZFOS+ Yacon Concentrate?

People managing conditions such as: diabetes, cancer or chemotherapy, kidney disease, obesity, fatty liver, menopause, constipation, impaired immunity, cardiovascular concerns, and gut health problems. NZFOS+ has been shown to assist in the management of disease when users are compliant with treatment.

Can NZFOS+ be used to treat diabetes?

Yes. The FOS in the roots of Yacon has a significant hypoglycaemic effect. Experiments have shown that consumption of yacon can significantly increase the number of insulin-positive pancreatic cells and glucagon-like peptide-1 (GLP-1), which can lower blood sugar levels and improve liver insulin sensitivity. In addition, the fermentation of FOS in yacon can produce short-chain fatty acids, which improve blood glucose levels through the direct activation of colonic free fatty acid receptors 2 and 3 (Ffar2 and Ffar3) through the intestinal hormone peptides YY (PYY) and GLP-1.

NZFOS+ is very sweet to the taste, is it really diabetic-friendly?

60% of the sweetness of NZFOS+ comes from its natural FOS. Since the human body does not have the enzyme to break down FOS, FOS does not enter the blood stream, hence it does not affect blood sugar. Not only that, because FOS are soluble dietary fibre, they can slow down the decomposition rate of free sugar in other foods that are simultaneously ingested to stabilize blood sugar. Therefore, diabetics can safely take NZFOS+.

In May 2019, the University of Sydney conducted a human test for the NZFOS+. The test results showed that NZFOS+ had a glycaemic index value of 40, which is categorized as Low GI. Diabetics can safely consume it.

FOS is not broken down, does not enter the blood, does not affect blood sugar, these are well understood, but how does Yacon regulate blood sugar?

To answer this question, we need to understand the two issues that affect blood sugar levels.

Insulin resistance & the imbalance of “insulin” and “glucagon”

Firstly, the FOS in NZFOS+ would reach the large intestine after passing through the digestive tract and selectively nourish the beneficial bacteria in the large intestine. Beneficial bacteria secrete short-chain fatty acids (SCFAs) during the fermentation of FOS. SCFAs enter the bloodstream through the large intestine wall and are transported to the body and improve the sensitivity of human cells to insulin. At this stage, the absorption capacity of glucose in the cells is improved, the glucose content in the blood is not accumulated, and the blood sugar level is also will return to the normal range.

Secondly, the secretion of glucagon in patients with type 2 diabetes could go out of control, breaking the balance between “insulin” and “glucagon”, causing glucose stored in the liver to be released into the blood stream. SCFAs stimulate the secretion of a hormone called GLP1 in the large intestine wall. GLP1 regulates the secretion of glucagon through pancreatic cells and the nervous system.

Can I take NZFOS+ if I have high blood sugar level, high blood pressure, and high blood lipid?

Yes. NZFOS+ can control blood sugar levels, regulate blood pressure, and lower blood fat. The effect of reducing triglycerides and “bad” cholesterol has been observed in human trials. According to a test by Jeong Sook Park, a daily intake of quantitative oligo fructose reduced the cholesterol index by 33% and the triglyceride index by 49% after 6 weeks.

Can I take NZFOS+ if I’m taking prescription drugs for diabetes or other conditions?

Yes.

Can I take NZFOS+ to treat diarrhoea?

Yes. Human experiments have shown that a daily intake of 12 grams of yacon syrup encourages the reproduction of healthy bacteria and decreases the incidents of diarrhoea.

Can I take NZFOS+ to treat constipation?

Yes. It has a significant effect on people with long-term constipation. Human experiments have shown that a daily intake of 12 grams of yacon syrup increases the frequency of bowel movements from an average of once every three days to an average of once a day.

How does NZFOS+ help to relieve constipation?

FOS is a kind of “water-soluble dietary fibre”. Water-soluble dietary fibre swells and shows a gelatine like state after being soaked in water. FOS can increase the weight and volume of faeces, hydrate the intestines, and relieve constipation.

How does NZFOS+ have a weight loss effect?

NZFOS+ has an effect on weight loss. Experiments show that obese women who took the experiment lost an average of 15 kg after taking 120 days of Yacon Syrup. NZFOS+ is rich in dietary fibre and can be taken before meals to increase satiety.

Why does NZFOS+ have the effect of preventing and assisting the treatment of arteriosclerosis?

Lipid waste such as cholesterol and triglycerides are the cause of arteriosclerosis.

The short-chain fatty acids (SCFAs) produced by the beneficial bacteria of the intestinal tract after fermenting FOS are absorbed in the large intestine wall and enter the blood, effectively lower blood cholesterol and triglyceride levels.

Clinical trials showed that after 90 days of continuous administration of FOS, subjects’ blood LDL cholesterol decreased by 16.55% and triglycerides decreased by 15.41%

How does NZFOS+ nourish intestinal beneficial bacteria and inhibit the pathogenic bacteria?

The number of microorganisms in the intestine of an adult is about 10 times that of human cells, and the total weight can reach 1-1.5kg, which is equivalent to the weight of the brain. In fact, their importance to the human body is no less inferior to our brain. Almost 90% of non-communicable diseases (NCDs: diabetes, fatty liver, obesity, mental illnesses such as depression and Alzheimer’s) can be traced back to the imbalance of intestinal flora.

Microorganisms form their own ecosystems in the human intestines. Like a society, there are “good guys”, “bad guys”, and the “conditional bad ones” who wait for opportunities to “commit crimes”. There is competition and cooperation between them. There are also different preferences, for example, beneficial bacteria prefer an environment where the pH is low or acidic, while pathogenic bacteria are the opposite, and they prefer an alkaline environment.

NZFOS+’s rich FOS is called “prebiotics” because FOS will enter the large intestine and become a “nutrient” for the beneficial bacteria there. This is because the human body does not have the ability to break down FOS so it enters the large intestine undigested.

FOS will nourish beneficial bacteria and stimulate the secretion of short-chain fatty acid (SCFAs) that are beneficial to the human body. Changing the intestinal environment to acidic creates a friendly environment for beneficial bacteria, and inhibits the growth and reproduction of pathogens.

Clinical trials have shown that after a 90 -day consumption of FOS, the colonization rate of the beneficial bacteria in the subject increased by 28.47%, and the colonization rate of harmful bacteria decreased by 12.04%

Can people with hypoglycaemia or normal blood sugar level take NZFOS+?

Simple answer: Yes. The role of NZFOS+ is to regulate blood sugar, not just lower blood sugar indiscriminately. It will also help to prevent diabetes. This is because the cells of diabetics are resistant to insulin (also known as insensitivity). Insulin cannot open cells, glucose cannot be absorbed by cells, or absorption rate is reduced. Excess sugar would be deposited in the liver, so obese people, pre-diabetics, and diabetics mostly have a fatty liver issue.

Back to the question, NZFOS+ will help to regulate insulin sensitivity, and therefore regulate blood sugar. It will have no negative effect on people with normal blood sugar or low blood sugar.

Detailed answer:

The process of metabolizing sugar and starch in normal people: Free sugar and starchy foods are ingested by the body, and are digested by digestive enzymes in the stomach and converted into glucose into the blood. Blood transports glucose to the body, and the pancreas senses food intake, which secretes a hormone called insulin.

Insulin and glucose flow in the blood at the same time. Insulin acts like a key, opening the body cells, and the opened cells absorb glucose. In this process, cells get what we often call “energy.” Excess glucose is taken up by the insulin to the liver and becomes a fat reserve.

People with diabetes and pre-diabetes: Free sugar and starchy foods are digested by digestive enzymes in the stomach and converted into glucose into the blood. Blood transports glucose to the body, and the pancreas senses food intake, which secretes a hormone called insulin.

Insulin and glucose flow in the blood at the same time. But the cells of diabetics are resistant to insulin (also known as insensitivity). Insulin cannot open cells, glucose cannot be absorbed by cells, or absorption rate is reduced. This is why people with diabetes may feel that they are “always hungry” or “always tired”, because their cells cannot absorb energy, and “hungry” is a signal the body sends. Excess sugar would be deposited in the liver, so obese people, pre-diabetes, and diabetics mostly have a fatty liver.

NZFOS+ can regulate insulin sensitivity. Its role is to regulate blood sugar. It has no negative effect on people with normal blood sugar or low blood sugar. So people with normal blood sugar level can eat NZFOS+ with confidence.

Can pregnant women take NZFOS+?

Yes. The number of Bifidobacterium in the expectant mothers who consumed FOS prebiotics was significantly higher than that of the control group, and there were no adverse effects on pregnant women or infants were found.

Can children take NZFOS+?

Recommended for over 1 year old.

If I have kidney or prostate disease, can I take this product?

Yes.

Can this product be used every day?

It can be taken every day. This product is a plant-derived puree and is a natural and healthy food that can be used regularly.

How do I take NZFOS+?

The recommended method is to take it directly or with water. FOS will absorb water in the colon so be sure to stay hydrated.

Should I avoid other health care products/drugs while taking NZFOS+?

No. NZFOS+ is made of 99.75% yacon concentrate, take it as a normal food product.

Can I take NZFOS+ with probiotics?

Yes. It can be taken with probiotics. Probiotics supply live bacteria from outside of our body, while NZFOS+ prebiotics nourish the good bacteria in our body and help them flourish.

Can NZFOS+ and honey be taken at the same time?

Yes.

Is it appropriate to take this product during the day or at night?

It is recommended to take in the morning and evening. For weight loss, consume 30 mins before meals to suppress appetite.

What are the storage instructions?

Refrigerate after opening. Consume within two months of opening.

Can I take NZFOS+ on an empty stomach?

Yes.

At what temperature can I heat this product?

50 degrees or less.

Can this product replace breakfast?

NZFOS+ contains high amount of dietary fibre, but it does not provide enough calories or other macronutrients for breakfast, so it is not recommended to use as a replacement for any meal.

How much should you eat a day?

6 to 20 grams, about 1 to 3 small wooden spoon (complimentary with purchasing)

My constipation has improved, but it seems my appetite has been reduced?

NZFOS+ has the effect of increasing satiety. People who want to lose weight should take Yacon half an hour before the meal. For people not looking to suppress appetite and/or children, taking NZFOS+ with or after meal is recommended.

How to incorporate NZFOS+ in to a low FODMAP diet for SIBO or IBS?

Low FODMAP diets to combat SIBO and IBS are intense and should be followed with the advice of a health professional. These usually cut out high FODMAPs for 2-6 weeks. During that time there is little fibre for bacteria in your gut to feed on so they die out and then you can slowly reintroduce foods to single out the ones that aggravate your symptoms.

Yacon Concentrate is an ideal form of fibre to support your diet because it naturally contains inulin fibre rather than a starch your body struggles to break down, let alone digest. This fibre supports the growth of good bugs like lactic acid bacteria. These beneficial strains create SCFAs which in turn make an environment that SIBO causing bugs cannot live in, and promote the development of a healthy intestinal barrier.

Clinical trials in reducing the cause of symptoms like constipation, diarrhea, bloating, and general discomfort used NZFOS+ Yacon Concentrate, and found that supplementing a probiotic strain with even a small amount of this fibre significantly reduced symptoms. As a concentrate this is one of the most pure ways to add a fibre without having to add big quantities of sugar or starchy mases that the body cannot digest. (We recommend starting with less than 6g daily and increasing as you become used to it).

How long does treatment with this product last?

120 day time periods were used in weight loss trials and in improving insulin sensitivity.  For constipation take as needed.

How long would it take to see changes if I take this product?

After taking NZFOS+ (with a healthy diet and exercise), you could expect to see the following changes:

After 3 days – increased gas, increased bowel movements – cleansing period

3-7 days – increased frequency of defecation, constipation gradually disappears – two-way adjustment period

7-21 days – relieve in abdominal discomfort, children become more concentrated, better sleep quality, and increased immunity – probiotic period

21-30 days – The bowel function is normal, a feeling of light and healthy – the unit adjustment cycle

30-60 days – blood pressure balances, skin is smooth, elasticity increases – function manifestation period

60-90 days – female waist and male beer belly reduced – functional moderate appearance period

90-150 days – decreased fat around liver, pancreas and other organs with better metabolic function – functional improvement.

Is NZFOS+ a health supplement or a food substitute?

Both, it is a healthy functional whole food that can be used as a sugar substitute, and is TAPS approved.

How is FOS both dietary fibre and prebiotic?

First of all, FOS is a “water-soluble dietary fibre”. The water-soluble dietary fibre will swell and show a gelatine state after being soaked in water. Therefore, FOS can help the hydrate intestines, increase the weight and volume of faeces, thus helping to relieve constipation.

Secondly, since the human body does not digest or decompose FOS, it eventually reaches the large intestine and selectively nourishes “good bacteria”. For this reason, FOS is a prebiotic approved by the WHO (World Health Organization).

What is the biggest difference between yacon from other countries and NZFOS+ yacon?

The biggest difference between yacon from other countries and New Zealand yacon is the concentration of prebiotics (FOS). New Zealand yacon are grown organically, the thickness of NZFOS+ is at least 80 Brix, and it has a standardised natural FOS level of at least 37 percent.

Why is the product made into syrup instead of powder or capsules?

The form of the syrup best preserves the FOS and other active ingredients from the yacon in the most natural way. Both milling and capsulation require multiple processing steps, and natural prebiotics will be spoiled if they are processed excessively.

Does this product contain any animal ingredients?

No. It is certified Vegan.

Does this product contain hormones?

No. But it can be beneficial for hormone health.

What is the difference between yacon and honey?

NZFOS+ is a low glycaemic index syrup that can be safely consumed by diabetics and can regulate blood sugar. NZFOS+ is rich in prebiotics and is a natural bifidus-factor that promotes the growth of healthy Bifidobacterium in our body. NZFOS+ is certified vegan.

Honey is not low GI, and may not be safe for diabetics or those with blood glucose problems to consume, neither will it improve insulin sensitivity. Although honey is antibacterial, little is known about its effect on gut health. Honey is not a vegan product.

What is the difference between other yacon syrup products and NZFOS+ yacon concentrate?

The biggest difference between is the concentration of prebiotics (FOS) and FOS/free sugar ratio. The thickness of NZFOS+ is 80 Brix, at least 60% of the total carbohydrate is FOS. It is certified low GI and approved for use as a therapeutic supplement not just a food or sugar replacement.

Is NZFOS+ organic?

The yacon used in NZFOS+ comes from three plantations in New Zealand. The yacon from the Kerikeri farm is organic and the other two farms – Pukekohe and Mangatawhiri – are in a transitioning period. New Zealand Pure Organic Certification takes a 3-year monitoring on not just the plantation but the entire supply chain, and we are working towards fully organic.

How long can a 275g jar last?

3 to 4 weeks.

Why not just eat yacon bought from a grocery shops?

Eating fresh yacon fruits may cause blood sugar rise.

The FOS content in yacon fruits fluctuates with seasonal, environmental, or pH level changes and would convert to free sugar. While FOS has no effect on blood sugar, free sugar does.

Diabetics should try to avoid free sugar intake. The purpose of the yacon concentration process is to preserve the natural FOS in yacon to the utmost extent. After years of experimentation, we have ascertained the ideal planting areas, conditions, climate, temperature difference, and even the spacing of the plants and the processing of yacon. Consuming NZFOS+ ensures that you are getting FOS instead of free sugar.

What is the difference between prebiotic and probiotic supplements?

Probiotics are live bacteria, while prebiotics are fibres like fructo-oligosaccharides (FOS) that occur naturally in yacon, and feed the probiotics.

Probiotics are external bacteria, we can add different strains according to different body constitutions and needs, Bifidobacterium have significant effects on gastrointestinal diseases. Prebiotics enter the gastrointestinal tract undigested and promote the absorption of nutrients by feeding probiotics such as Bifidobacterium.

The human immune system may not recognize externally ingested bacteria from supplements and respond negatively to protect its self. These bacteria may also be killed by gastric acid.

What is the difference between NZFOS+ and enzymes?

They both assist with: Cleansing the bowel, weight loss, antibacterial, and anti-inflammatory responses.

However: an enzyme is a protein -often found in food like pineapple- that your body uses for digestion and other metabolic processes. NZFOS+ is a fibre that comes from yacon and will ferment in the body.

If you supplement enzymes often, it may change the structure of your own enzymes, which will affect your health. Most enzymes on the market now contain probiotics, but contain less prebiotics and are not natural.

Can NZFOS+ fibre cause bloating?

When bacteria eat (ferment) fibre they release gas that stretches the colon and the fibre will also draw water into the colon. This is the cause of uncomfortable bloating. NZFOS+ however has shown improvements in the speed of bowel movements, and relief of IBS symptoms like bloating. Start with a dose of 3g and work your way up as your gut allows. Case Studies see an improvement with small doses, although some symptoms like constipation may be relieved by moderate regular doses.
