Scientific Studies

STUDIES:

Mechanism of Problem - AKA, proof that Sucrase is the Problem:
  1. 1962 - 1964 Studies -
    1. They basically realized that there were ZERO cases of diabetes in Greenlanders. Diet was a huge reason they believed this happened. They ate seal and whale meat, almost no carbs (wheat, fruit, and other carbs don't grow in the arctic).
  2. 2016 Greenland Study - Identification of Novel Genetic Determinants of Erythrocyte Membrane Fatty Acid Composition among Greenlanders
    1. This is the original study that found that these Greenlanders had a different way of metabolizing fatty acids vs. other people. They were basically knew that there was a difference between these greenlanders that made them healthier, but didn't know why. This study was able to narrow it down to 6 different associations
  3. 2020 Greenland Inuit Study - The derived allele of a novel intergenic variant at chromosome 11 associates with lower body mass index and a favorable metabolic phenotype in Greenlanders
    1. So this was the original study that found this specific gene (the one that controls whether someone creates sucrase or not) resulted in better metabolic health
      1. Stage 1 BMI-association analyses = 4,626 Greenlanders.
      2. Stage 2 replication and meta-analysis were performed in additional cohorts comprising
        1. 1,058 Yup'ik Alaska Native people, and
        2. 1,529 Greenlanders.
    2. variant was associated with:
      1. a leaner body type (weight, -1.68 (0.37) kg;
      2. waist circumference, -1.52 (0.33) cm;
      3. hip circumference, -0.85 (0.24) cm;
      4. lean mass, -0.84 (0.19) kg;
      5. fat mass and percent, -1.66 (0.33) kg and -1.39 (0.27) %;
      6. visceral adipose tissue, -0.30 (0.07) cm;
      7. subcutaneous adipose tissue, -0.16 (0.05) cm, all p = 0.0002),
      8. lower insulin resistance (HOMA-IR, -0.12 (0.04), p = 0.00021), and
      9. favorable lipid levels (triglyceride, -0.05 (0.02) mmol/l, p = 0.025;
      10. HDL-cholesterol, 0.04 (0.01) mmol/l, p = 0.0015).
  4. 2022 Greenland Inuit Study - Loss of Sucrase-Isomaltase Function Increases Acetate Levels and Improves Metabolic Health in Greenlandic Cohorts
    1. Study - Greenland Inuits with Homozygous Trait do NOT produce Sucrase in their gut. As a result, sugar is not metabolized, and it's not absorbed by the body
    2. This study wanted to test to see if this gave them a better metabolic profile. They found these Inuits:
      1. Lower body mass index (β [standard error], –2.0 [0.5] kg/m2; P = 3.1 × 10–5),
      2. body weight (–4.8 [1.4] kg; P = 5.1 × 10–4),
      3. fat percentage (–3.3% [1.0%]; P = 3.7 × 10–4),
      4. fasting triglyceride (–0.27 [0.07] mmol/L; P = 2.3 × 10–6), and
      5. remnant cholesterol (–0.11 [0.03] mmol/L; P = 4.2 × 10–5).
    3. These results were then confirmed in knockout mice.
    4. Notable that these people ate the SAME calories as other people, but had a better metabolic profile.
      1. Further analyses suggested that this was likely mediated partly by higher circulating levels of acetate observed in homozygous carriers (β [standard error], 0.056 [0.002] mmol/L; P = 2.1 × 10–26), and partly by reduced sucrose uptake, but not lower caloric intake.
    5. Additional Study Breakdown/Language
  5. 2023 Study - Results have not been published. This is the study that would look specifically at how the unique greenlander's bodies respond to sugar intake. Specifically, if eating frozen dinner, processed foods, as opposed to whale and seal meat, would cause diabetes.
    1. Western diet: high in starch mostly from bread and pasta. The diet had a relatively high content of sucrose from fruit yogurt, fruits, orange juice, and biscuits. Dinner meals were frozen convenience meals, i.e. pasta dishes and pizza, supplied by extra vegetables. The nutrient composition expressed in percentage of total energy derived from each macronutrient, i.e. energy% (E%), was:
      1. Sucrose 11%
      2. Other carbohydrates: 47–49 E%
      3. Protein: 14 E%
      4. Fat: 25 E%
    2. Traditional Greenlandic diet: high content of fish, both raw and dried, reindeer meat, dried whale meat, and eggs, as well as blueberries, an arctic berry which do not contain sucrose. The majority of the foods were provided frozen and participants prepared dinner meals. The nutrient composition was:
      1. Sucrose: 0 E%
      2. Other carbohydrate: 5 E%
      3. Protein: 36 E%
      4. Fat: 57 E%
Mechanism of Solution - AKA, proof that L-Arabinose is the Solution:
  1. 2018 News Release
    1. Kraft Heinz has sponsored work by Harvard scientists to make an enzyme that turns sugar into fiber. Doesn't work on Sucrase, but is interesting to see that this idea to “Build a wall that prevents sugar from entering blood stream” is not new. But the solution has been under our noses this whole
  2. (2020) Division of Human Nutrition and Health, Wageningen University (Netherlands)
    1. Human Study
      1. Replacing sucrose by L-arabinose in drinks reduces glucose and insulin responses.
      2. L-arabinose in water does not affect glucose or insulin levels.
      3. Replacing sucrose by L-arabinose in cereals does not affect glucose responses.
      4. Replacing sucrose by L-arabinose in cereals lowers peak insulin levels.
        1. Peak Insulin Levels for Cereal 0%, 8%, and 13% arabinose
        2. 42mU/L, 32mU/L, 34mU/L
  3. (2022) Cambridge Unviersity - L-arabinose delays/prevents Sugar absorption
    1. L-arabinose co-ingestion delays glucose absorption derived from sucrose in healthy men and women: a double-blind, randomised crossover trial
  4. 2022 - Division of Human Nutrition and Health, Wageningen University (Netherlands)
    1. Prevented a glucose spike when it also included starches and fats (like in a regular diet)
    2. Human Study, randomized cross-over trial
    3. Had people drink 1 of 6 drinks,
      1. 50g sucrose (sugar), 50g sucrose + starch, 50g sucrose + fat
      2. All of the above + 5g L-arabinose
    4. With L-Arabinose Glucose peak lowered by
      1. 15%, 8%, and 7%
    5. With L-Arabinose Insulin peak lowered by
      1. 52%, 45%, and 29%
  5. Chinese Study (2013)

      1. Human Study
      2. 6 mo trial, 43 volunteers
      3. Tested various metrics at month 2, 4, and 6.
      4. Arabinose added to drink once per day. No diet changes or exercise requirements.
      5. Our results showed that the L-arabinose decreased waist circumference, TC, fasting glucose, serum uric acid, ALT and slightly increased HDLCand slightly decreased diastolic blood pressure after 6 months.
      6. A tendency for decreased waist circumference, TC, fasting glucose, serum uric acid, ALT after 2, 4 and 6 months of treatment with L-arabinose was observed
      7. Weight changes;
        1. Base(72.2±13.0kg),
        2. 2 months Post-treatment (71.5±13.3kg)
        3. 4 months Post-treatment (71.3±13.0kg)
        4. 6 months Post-treatment (70.8±13.6kg)
      8. Waist Circumfrence
        1. Pre-treatment (93.0±8.6cm),
        2. 2 months Post-treatment (92.1±8.5cm) was not statistically significant (P>0.05), the
        3. 4 months Post-treatment (90.6±8.7cm)
        4. 6 months Post-treatment (89.9±8.5cm)
      9. Fasting Blood Glucose
        1. Pre-treatment (113.4±26.1 mg/dL)
        2. 2 months Post-treatment (108.3±18.4 mg/dL)
          1. decreased but was not statistically significant (P>0.05)
        3. 4 months Post-treatment (106.2±18.2 mg/dL)
          1. decreased but was not statistically significant (P>0.05), the
        4. 6 months Post-treatment (98.8±15.3 mg/dL)
          1. decreased and had statistically significance
Mechanism of Solution 2 - Proof that Arabinose + Chromium was the Dynamic Duo:
  1. San Antonio University Study (2011), 20 people over 4 weeks, took Chromium + L-Arabinose - lowered circulating insulin and circulating blood glucose levels (even after eating food)
  2. 2020 Meta-analysis (27 Studies)
    1. Twenty-eight studies reported fasting plasma glucose (FPG), insulin, hemoglobin A1C (HbA1C) and homeostatic model assessment for insulin resistance (HOMA-IR) as an outcome measure. Results revealed significant reduction after chromium supplementation in
      1. FPG (weighted mean difference (WMD):
        1. -19.00 mg/dl, 95% CI: -36.15, -1.85, P = 0.030; I2: 99.8%, p < 0.001),
      2. insulin level (WMD:
        1. -12.35 pmol/l, 95% CI: -17.86, -6.83, P < 0.001),
      3. HbA1C (
        1. WMD: -0.71 %, 95% CI: -1.19, -0.23, P = 0.004) and
      4. HOMA-IR
        1. (WMD: -1.53, 95% CI: -2.35, -0.72, P < 0.001; I2: 89.9%, p < 0.001)
  3. Competitor Product Swipe:
    1. According to a study by Harvard Medical School, chromium safely lowers blood sugar levels and improves insulin sensitivity. When your body lacks chromium, which is likely your situation right now, your ability to lose weight is held back from a cellular level. The right amount of chromium as found in every serving of GlucoTrust helps to unleash your metabolism and kick it into high gear. Your body stops storing fat and starts melting it away like a block of ice under the hot sun.
Mechanism of Ingredients - AKA, proof that Supporting Ingredients Help Solution:
  1. Gymnemma
    1. 2021 Study on GlycaCareII (proprietary herbal formulation that includes Gymnemma)
      1. Compared GCII to Metformin for 120 days
      2. Twice a day treatment for 120 days with GlycaCare-II led to a statistically significant change in HbA1c (p < 0.001), FBS (p < 0.001), PBS (p < 0.001) on both prediabetic and newly diagnosed diabetic patients. GlycaCare-II showed a similar potential as metformin in the treatment of T2DM. In the prediabetic group, both GlycaCare-II and metformin were comparable for all the hyperglycemic index parameters. In the case of newly diagnosed diabetic patients, GlycaCare-II showed a significantly better reduction for PBS (p = 0.026) as compared to metformin, while all other parameters in the diabetic panel were comparable. No adverse events were reported throughout the trial period.
    2. 2021 Metaanalysis
      1. Our meta-analysis consisting of 10 studies with a total of 419 participants showed that GS supplementation significantly reduces
        1. fasting blood glucose (FBG)
          1. (SMD 1.57 mg/dl, 95% CI 2.22 to -0.93, p < .0001, I2 90%),
        2. postprandial blood glucose (PPBG)
          1. (SMD 1.04 mg/dl, 95% CI 1.53 to -0.54, p < .0001, I2 80%), and
        3. glycated hemoglobin (HbA1c)
          1. (SMD 3.91, 95% CI 7.35 to -0.16%, p < .0001, I2 99%) compared to baseline.
      2. Further, our study also found that GS significantly reduces
        1. triglycerides
          1. (SMD 1.81 mg/dl, 95% CI 2.95 to -0.66, p < .0001, I2 : 96%), and
        2. total cholesterol
          1. (SMD 4.10 mg/dl, 95% CI 7.21 to -0.99, p < .0001, I2 : 98%) compared to baseline
