Good Green Stuff

Pregnancy & Breastfeeding

  • Is Good Green Stuff safe to take during pregnancy?

    There is nothing in Good Green Stuff that is contraindicated during pregnancy. We have designed Good Green Stuff to be a safe, every day formula for all adult populations. Note: Rosemary is contraindicated for pregnancy in high (therapeutic/herbal medical) doses but the miniscule amount in Good Green Stuff is completely safe.

  • Can I take Good Green Stuff while breastfeeding?

    According to our health advisors, Good Green Stuff is safe during pregnancy and breastfeeding and may help provide some of the additional nutritional requirements during this time. However, every individual is different and may have specific requirements or a need for special for caution. We always advise women who are pregnant or breastfeeding to seek independent advice from their health practitioner first.

  • I am pregnant and am concerned that there is kelp in Good Green Stuff. Could this affect my thyroid?

    The amount of kelp contained within Good Green Stuff is approximately 60mg, and the total iodine content of Good Green Stuff from kelp and marine algae is around 154mcg – equivalent to the daily dietary recommended intake for adults, but less than the recommended intake for pregnancy and breast-feeding . Iodine in adequate amounts is essential for creation of thyroid hormones. The amount in Good Green Stuff is supportive and should not cause adverse effects.

  • Does Good Green Stuff provide enough Folic Acid during pregnancy?

    Good Green Stuff contains Folate (methyltetrahydrofolate), the natural form of Folic Acid. Having enough L5MTHF (Folate) is imperative during pregnancy to help reduce the risk of neural tube defects in the baby. Many people lack the ability to completely convert synthetic Folic Acid into Folate. This is problematic not only because the body if not getting the nutritional and protective benefits, but un-metabolised Folic Acid has been shown to increase cancer tumour growth. The amount of added Folate in our formula, combined with that naturally sourced thought diet should be adequate for a healthy pregnancy however you should always consult with your health care practitioner.

Ingredients & Formula

  • Is the beta-carotene in Good Green Stuff naturally derived or synthetic?

    Our beta-carotene is derived from an algal source (Dunaliella salina) that also provides other carotenoids; alpha-carotene, lutein and zeaxanthin.

  • Are the probiotics in Good Green Stuff still alive and viable?

    The best research we have to date shows that the viability of probiotic compounds is good for many months so long as the product is kept relatively cool. Be sure to keep the product in the bottom of the pantry or the fridge to preserve viability.

  • Why is there no Iron in Good Green Stuff?

    Iron is an essential mineral however it hasn’t been added to our formula because a significant amount of people (especially middle-aged males) may in fact have iron levels that are too high rather than too low. Genetic iron overload (haemachromatosis) is also a relatively common genetic condition. High iron levels are very damaging to the body, encouraging oxidation linked to heart disease and pre-diabetic conditions. We suggest that anyone thinking about supplementing with iron has their levels checked and a suitable amount prescribed by a qualified health practitioner.

  • Is Vitamin D included in the formula?

    Vitamin D is an extremely important nutrient and one that many people need to supplement. We have included a vegan (algal derived) Vitamin D3 (cholecalciferol) that meets the dietary recommended intake. The alternative, generally used in supplements —Vitamin D2, is not what the body produces naturally (which is D3) and there are serious questions being asked about its use and efficacy. For example a recent meta-analysis by the Cochrane Database showed a mortality risk reduction in those using Vitamin D3, but not those using Vitamin D2.

  • I am sensitive to caffeine, is it ok for me to use the product?

    Due to their amazing antioxidant potential, Good Green Stuff contains green tea and cocoa bean extracts. While the antioxidants remain high, the caffeine content diminishes during the extraction process. Even without extraction, the maximum amount of caffeine that could be expected from the combined amount of green tea and cocoa used in Good Green Stuff would be under 7mg per serve (approx. 1/25th of a small brewed coffee). In reality, after extraction, the amount of caffeine is negligible. Good Green Stuff should be fine even for caffeine sensitive individuals.

  • Is Good Green Stuff Soy Free?

    Yes. Unlike many other products we use sunflower lecithin in place of the more common soy lecithin so that we can be sure our product is soy-free.

  • How is Good Green stuff labelled 'gluten free' when it contains barley and wheat grass?

    The barley and wheat grass in Good Green Stuff are the growing portion of the plant, not the grain. The grain is the part that contains gluten. Every batch of Good Green Stuff is tested for gluten and is certified gluten-free.

  • I have read that many foods and supplements are irradiated. How does this affect the Good Green Stuff formula?

    None of the ingredients in Good Green Stuff are irradiated! This would potentially damage the ingredients, reducing nutrient content and potentially causing allergenic problems. We do not irradiate our products.

Health Conditions, Medications & Diets

  • Can cancer patients take Good Green Stuff?

    There is no reason why cancer patients cannot take Good Green Stuff. The formula is designed as an every day nutritional supplement. It provides a comprehensive blend of whole food derived nutrients that simply help to provide a base of great nutrition. This will benefit anyone needing to ensure quality nutrition to support health and recovery (including cancer patients and those undergoing chemotherapy) whilst avoiding any potential problems of megadosing certain vitamins and mineral, which may be a concern. If undergoing chemotherapy please consult with your oncologist if you have any concerns about supplementation.

  • I have been diagnosed with Candida Albicans overgrowth. Can I take Good Green Stuff?

    Yes! The prebiotic and probiotic nature of Good Green Stuff makes it a great addition to an anti-candida strategy. It is also extremely low in sugar and is yeast-free. The general nutritional support provided by super-food greens, berries, herbs and added vitamins and minerals, and the ability to support detoxification processes and stress response make it a great choice for you.

  • I have Chronic Fatigue Syndrome. Can I take Good Green Stuff?

    Yes! Chronic Fatigue is often characterised by dysfunctional stress responses and impaired adrenal function. The general nutritional support, added vitamins and minerals and especially the ‘adaptogenic herbs’ which help the body to respond to stress more effectively can help the body in its recovery from Chronic Fatigue or Adrenal Fatigue.

  • I am currently undergoing chemotherapy, can I use Good Green Stuff?

    We always suggest that anyone undergoing any drug treatment should consult individually with a suitably qualified health practitioner to discuss their specific needs. Good Green Stuff, though, as a whole food based nutritional support formula may help the body to recover from chemotherapy. There is some discussion as to whether antioxidants may inhibit chemotherapy’s effectiveness, however this discussion tends to involve the use of isolated and therapeutic doses of antioxidants, not whole food based formulas that provide general support for health and wellbeing.

  • Is Good Green Stuff safe for Coeliacs?

    Yes. Every batch of Good Green Stuff is independently tested for gluten and is certified as gluten-free. Some confusion exists due to the addition of the highly nutritive plants wheat grass and barley grass. It is important to remember that these are the growing portion of the plant – not the grain which contains gluten.

  • Is Good Green Stuff suitable for Vegans or Vegetarians?

    Yes, Good Green Stuff is suitable for both vegetarians and vegans. None of the ingredients in Good Green Stuff are derived from animal products.

  • Is Good Green Stuff Kosher?

    While not officially certified, the ingredients in Good Green Stuff and the manufacturing facility all comply with Kosher practices.

  • Is Good Green Stuff safe for diabetics?

    Good Green Stuff is completely safe for diabetics. There are less than 3 grams of carbohydrate per serve so the effect on blood glucose is minimal; and, at around 40 calories per serve, any effect on insulin in type 2 diabetics and those with metabolic syndrome and pre-diabetic disorders is almost nil. Good Green Stuff may even help those with diabetes due to the inclusion of ingredients such as chromium and green tea extracts that aid glycaemic control and improve insulin sensitivity.

  • Is Good Green Stuff Paleo-friendly?

    Good Green Stuff is Paleo friendly. The challenge with legumes on a Paleo or Primal style diet is that ‘anti-nutrients’ that legumes contain. While the product contains pea protein, our patented isolation process effectively removes these (phytate, lectins, saponins and trypsin inhibitors) leaving a highly digestible protein free of the problems associated with legumes.

  • Why is it important that the product is ‘alkaline’?

    Our bodies must maintain finely controlled pH levels (most importantly in our blood) in order to survive and thrive. Modern diets and lifestyles often cause an increase in acidity in the body which then needs to be ‘buffered. If the diet is not providing enough of an alkaline buffer, the body will start to break down muscle and tissue to free up ‘basic’ (alkaline) compounds. Good Green Stuff helps to restore the body’s pH balance by providing an influx of these highly alkaline-forming ingredients.

  • Is Good Green Stuff safe for Children?

    According to Australian and New Zealand regulations, Good Green Stuff is suitable for children aged 4 and over. However the dosage for children aged 4 – 14yrs is half that of an adult (1/2 teaspoon). Regulations may vary from country to country but, in any event, we do not recommend Good Green Stuff for anyone under the age of 4.

  • Can I take Good Green Stuff while I’m on blood pressure medication?

    Yes – there is no problem with taking Good Green Stuff with hypertension. It is important to monitor your blood pressure though as the dietary nitrates in vegetable greens and superfoods (such as beets) found in Good Green Stuff may help to normalise blood pressure, potentially causing blood pressure to become low. Monitor blood pressure and consult with your doctor if blood pressure changes so that your medication can be adjusted.

  • I have recently been diagnosed with IBS. Will Good Green Stuff help me?

    Yes! Good Green Stuff will help to encourage more effective digestion due to its mucilaginous and soothing ingredients (such as slippery elm) and microbiotic ingredients that help to preserve proper levels of benficial bacteria in the bowel. Remember that the addition of foods that contain microbiotics and beneficial fibres can cause urgency or cramping if taken in too great an amount. The body needs a little time to adjust. We suggest starting on a reduced dose (1/2 dessert spoon) for a week and then increasing to the full dose. IBS almost always has other causative factors too, including stress and anxiety. Seek out a practitioner suitably qualified in the mind-body aspects of health to address this.

Product & Usage

  • Why is the Good Green Stuff in powder form?

    There are several reasons why we decided to stick with powder as compared to pill or capsule form for Good Green Stuff: 1. Quantity - It is simply easier for us to get a viable dose in a scoopful of Good Green Stuff than taking the equivalent amount of capsules, which many people would find hard to swallow! 2. Destruction of nutrients in processing - The encapsulation and tableting processes introduce an extra level of processing that could potentially damage some of the nutrients and compounds in Good Green Stuff. 3. Ease of digestion - Powder products generally digest more efficiently and effectively as there is no capsule to first break down, plus we can avoid using artificial binders and fillers that would be needed to put the product into tablet form.

  • Why is there sometimes a little residue left in the glass when I take my Good Green Stuff?

    Good Green Stuff is refined only enough to make it mixable, whilst also preserving some of the more fragile nutritional compounds. Simply make sure that you continue to mix/swirl the glass whilst you drink. Inevitably, some of the heavier particles will naturally settle if you allow it to sit for a while before consumption.

Clean Lean Protein

Health Conditions, Medications & Diets

  • Is Clean Lean Protein Vegan/Vegetarian friendly?

    The peas used in Clean Lean Protein are a vegetable source and the natural flavourings are all plant derived, making Clean Lean Protein 100% vegetarian and vegan.

  • Is Clean Lean Protein ok for Coeliacs?

    Yes. Clean Lean Protein is certified gluten free so it is safe for coeliacs.

  • Why Nuzest claims Clean Lean Protein is ‘allergen-free’

    It is important to recognise that any individual can be allergic to almost any food, the allergenicity often being related to protein components. The use of the phrase ‘allergen-free’ or similar in the food industry generally refers to the avoidance of any foods that contain foods for which food labelling laws require allergen labelling (i.e. major food allergens). In the USA, this means compliance with the Food Allergen Labeling and Consumer Protection Act of 2004. Note 21 USC 301 of this Act1states: “approximately 2 percent of adults and about 5 percent of infants and young children in the United States suffer from food allergies” and “[e]ight major foods or food groups — milk, eggs, fish, Crustacean shellfish, tree nuts, peanuts, wheat, and soybeans — account for 90 percent of food allergies.” Two of these allergen-containing foods, peanuts and soybeans, are of course legumes, and there is some evidence for cross-reactivity among different members of the leguminous plant family, of which peas, and the golden (or yellow) pea (Pisum sativum) are members. This is the pea species from which the pea protein isolate in Clean Lean Protein is derived. Potential sources of allergens in peas Some active lectins can also bind to the mucosa of the intestinal wall damaging the epithelial cells, depressing nutrient absorption, reducing activity of brush border enzymes, and causing hyper secretion of endogenous protein with the shedding of damaged cells.3This does not occur with pea lectins. Pea protein consists of approximately 55-65% globulins and 20-25% albumins (Cosucra, personal communication) and  pea lectins are components of these albumins. Importantly, studies on pigs (there are no comparable human studies) show that pea lectins are not digested in the gastro-intestinal tract and triggered no antibody reactivity.3 Cross-reactivity The proteins that induce allergenicity and anaphylaxis in peanuts have been extremely well studied. While 11 peanuts allergens have been described, most reactions have been attributed to four families of allergens, these being cupin (Ara h 1), prolamin (Ara h 2, 6, 7, 9), profilim (Ara h 5), and bet v-1-related proteins (vicilins) (Ara h 8).4 A search of the peer-review literature PubMed) reveals only a single paper relating specifically to the allergenicity of Pisum sativum.5This paper considers only the theoretical allergenicity based on IgE binding capacity at different maturation levels of the peas. As with all allergens, the possibility, however small, for allergic reactions and cross-reactivity cannot be dismissed. Cross-reactivity between peanut allergy and peas has been described,6 but is only rarely considered to be clinically meaningful.7 Wensing and colleagues have noted positive skin prick tests to pea and peanut and increased IgE in 3 patients with a history of anaphylaxis to peanut exposure. Vicilin (and to a lesser degree convicilin), proteins found in peas, are believed to be the molecular basis for this cross-reactivity. 7, 8 In a study of 12 peanut-sensitive children, positive skin-prick results for pea were seen in 8 participants, with 11 exhibiting positive skin-prick test (> 3mm wheal) for peanuts. However, IgE levels were, overall, less than half (mean = 10 and 23 for PS vs AH respectively).9 In a larger study of 75 peanut-allergic children, 25 one-third) were determined to be at high risk of pea sensitivity.10 So, there is the potential for cross-reactivity of peas and pea flours with those who are allergic or sensitive to peanuts. Do these findings apply to pea protein isolates? The proteins involved with cross-reactivity are protein lectins (haemagglutinins), such as the various vicilins (particularly abundant in kidney beans).11 The isolation process of pea protein isolate used in the manufacture of Clean Lean Protein effectively removes all detectable lectins. Manufacturing batches are regularly evaluated for lectins and to-date, no detectable lectins have ever been found in the finished pea protein isolate used by Nuzest.  It is for this reason that Nuzest makes the “lectin-free” claim on its Clean Lean Protein product range. NOTE: As any food can induce an allergic response in a given individual, and because of the potential (albeit very low) risk of cross-reactivity between different members of the legume family, caution should always be exercised, especially in the case of a known history of anaphylactic reactions to peanuts or any other leguminous food or ingredient. In such cases, we suggest consulting with your primary care physician prior to using any supplement or food containing plant proteins that have not had a past history of safe consumption.   References

Ingredients & Formula

  • Can vegan or plant-based proteins be considered raw?

    While some companies on the market like to claim their protein powders are “raw” the truth is this may be a bit misleading. Raw foods, by nature, are very minimally processed, however when creating protein powder this is nearly impossible. The ingredients that go into protein powders need to be milled, processed, and sanitized in a way that makes them both safe and effective for consumption, which does involve short periods in which the water temperature used to isolate the protein is raised to over 40oC, although the resulting protein is in no way denatured, damaged or rendered less digestible. The raw material in Clean Lean Protein, Pisane® made by Cosucra in Belgium, is in our view the highest quality pea protein isolate available. The unique process that Cosucra uses to extract the protein component out of European Golden Peas (Pisum sativum) results in a protein with an exceptional amino acid profile that is very close to that of whey protein or egg white, both of which are allergenic. The water-based, solvent and chemical free extraction process delivers a protein that is 98% digestible and free from common allergens (i.e. it is hypoallergenic). It is also free of elements of the pea (e.g. lectins) that might adversely impact absorption or contribute to unpleasant flavour notes or odours (a common problem with many other pea proteins). To summarise, while no heat is added to the finished product, it is a bit misleading to label the product as truly “raw”. Unfortunately at this time there is no government standards or definition around this term, which allows for a lot of grey area when it comes to using the term on a product’s label.
