    LUMII 400W SUNBLASTER HPS GROW LAMP The 400w LUMii SunBlaster Auto HPS grow lamp could possibly be the perfect dual spectrum grow lamp. With increased output and an emphasis on the blue spectrum, they’ll encourage equal amounts of growth during the vegetative stage and bloom, meaning no need to change lamps for optimum flower production. The crystal glass used on the 400w LUMii SunBlaster has a constant thickness that allows the light to emit evenly. LUMii also avoided using a barium film which can darken or blacken the glass, giving reduced output, so with less gas impurities, the emitted light is a lot cleaner and more stable. Combined with an E40 mechanical double layer fitting, the SunBlaster has a lifespan of 32,000 hours and the output is as follows: 140 lumens per watt / 56000 lumens in total Now do the same for this.

Worth reading to better understand blood sugar, but don’t limit yourself to this one resource
Format: Hardcover
My mother had type 2 diabetes and ultimately died from related kidney failure. For years I have exercised and managed my diet in an effort to avoid a similar fate. I was therefore stunned during a recent doctor's appointment when it was revealed that my hemoglobin A1c was above normal limits. I immediately ordered a continous glucose monitor and was dismayed to see that my blood glucose levels were regularly exceeding what would be considered normal. I am now trying to learn as much as possible about preventing these elevated glucose levels. In my research I was led to Jessie Inchauspe (Glucose Goddess on Instagram) and decided to buy her book, The Glucose Revolution. I will say that the majority of the information in this book is available for free on her Instagram account. However, I like the simplicity of reading through the book rather than scrolling through posts and reels. The author gives a thorough overview of glucose, explaining the different forms and how they act in our bodies. She explains glucose spikes and has a really good explanation of what the hemoglobin A1c test is measuring. She then shares 10 hacks to help lower your blood sugar levels that I feel are relatively easy to incorporate into your eating plan. Some of them, like eating dessert over a sweet snack (eat a sweet food after a meal rather than on its own) were things that I have already been doing intuitively. I do wonder at the description of our stomachs as a sink and the intestine as the pipe below. She claims that when we eat carbs first, they flow uninterrupted into the intestine. Drawing on information from my college nutrition classes many years ago, I seem to remember that chemical digestion begins in your mouth and that because of the churning in your stomach, the food that you eat will all be mixed around and therefore it doesn't really matter what order you eat your foods in. That being said, it's a relatively minor thing to eat a veggie starter and/or eat foods in the described order. I also question the idea that our blood sugar shouldn't rise more than 30 points after eating. If my blood sugar is at 80, that means after eating my glucose level should not be above 110. That is well below the generally accepted rise to 140. I'm not saying that we should always be going to that level, but even a modest rise to 120 would not be accepable according to the standards presented in the book. Of note, the author does not have diabetes or prediabetes and started the Glucose Goddess after working for a company that was developing continuous glucose monitors. Overall, I do think this book is worth reading to better understand blood sugar. I wouldn't limit your knowledge to just this one source of information though. I've been slowly working through articles and videos published on the Nourished by Science website. I really appreciate the perspective offered there. Women entering menoupause might want to investigate the effects of decling estrogen on their blood glucose levels too. The New Menopause by Dr. Mary Claire Haver is a fantastic book on this stage of life.

Glucose Revolution is very healthy and has specific recommendations
Format: Hardcover
This was recommended by an outstanding organization that addresses discomfort and overall health and wellbeing, Pearson and Weary. This gives recommendations to stabilize glucose and flatten curves. There was beneficial discussion of the use of fiber which slows the body's glucose absorption. Comparisons of orange juice (lacks fiber) vs. eating an orange (includes fiber) that does not create a glucose spike. Evaluated sugar as a cause of not feeling well and leading to glucose spikes which can lead to heart disease, type II diabetes and cognitive decline. Glucose spikes also lead to inflammation which is a common source of illnesses: strokes, chronic respiratory disease, heart disease, liver disease, diabetes and obesity. When glucose curves are flattened the body burns fat. The book reviews the short term and long-term effects of glucose spikes. Cornell University which I attended as an undergraduate stated there is a specific order to reduce glucose spies by 73% that includes fiber 1st, protein and fat 2nd, starches and sugars last. Other recommendations: (1) never drink fruit juice as sugar from fruit is missing the fiber "resulting in disastrous blood glucose levels." (2) Breakfast cereals is one of the "worst ways to begin your day as it always creates tremendous glucose spikes." Choose savory breakfast can include yogurt, meat, cream cheese, protein powder, butter, eggs, and seeds. Toast alone increases glucose spikes but added peanut butter or avocado can minimize spike. (3) artificial sweeteners can increase insulin rise and havoc in the gastrointestinal system. (4) fasting has benefits for 8-12 hours. (5) snacking increases obesity. (6) add one tablespoon of apple cider vinegar to a large glass of water which is best 20 minutes before eating. This approach after 3 months led to a loss of 2-4 pounds. Vinegar stimulates mitochondria to burn more fat. (7) exercising after eating can also reduce glucose spike and is beneficial within 70 minutes of food consumption.

READ THIS AND CHANGE YOUR LIFE FOR THE BETTER NOW!!!
33% of Americans are verging on type 2 diabetes and do not know it. This should make you run to get this book! Following Glucose goddess on Instagram and got her book as well. It is easy to read, with fun illustrations by the author. She has truly helped me so much with my insulin resistance and managing my glucose spikes. "Lifestyle optimization" is an essential for everyone. Why wait until you are diagnosed? These hacks are simple, fun, and super easy. Her audiobook is also out now and is read by the author!! Which is awesome. What makes this book even MORE useful though, is if you invest in a continuous glucose monitor (CGM) and have the app. I had the Freestyle Libre sensor. Each sensor lasts 2 weeks on the skin and logs your real-time glucose levels 24/7. Way better than doing the old fashioned painful and wasteful lancet and test strips. Although you can verify your CGM occasionally using the lancet, and see how accurate the CGM is. You can have a CGM prescription written for you if you INSIST at your nurse practitioner's. (NPs are WAY more open to this kind of experimentation and self-monitoring...I got the rebuff from the doctor, HA!) What is so sad is that the healthcare system is so broken that insurance will NOT cover a CGM UNTIL you have full-blown type 2 diabetes and are dependent on exogenous insulin delivery. OR if you are a type 1 diabetic and born without the ability to process glucose. Sad huh? The FDA wants you sick, fat, ugly, and miserable. We are MUCH better desperate customers then...willing and eager to take any pills to solve the problems! Let's not be proactive and encourage the PATIENT to take measures against type 2 diabetes, right? So there are MANY benefits of managing glucose. Fairly effortless weight loss actually. In this book she dives into nutrition science and the biochemistry of different sugars as well. She has so much credibility and science-driven data backed up by her own personal journey as well as many peer-reviewed articles. Thank you Jessie!

Really Good Book & Inspired Me to Take Action
Format: Hardcover
After I finished reading the book, I asked my doctor for a Continuous Glucose Monitor. For two weeks, I reduced my carb & sugar intake & was able to keep my glucose in the "steady" range. Then, I ate an oatmeal cookie without pre-eating any fiber or protein. BIG SPIKE! One cookie sent my glucose soaring. I can't even imagine what happens to my body when I eat 1/2 pound of candy. This book was written in a very understandable way & it inspired me to start tracking my glucose levels. I recommend reading this book. And there is definitely something about seeing the effect on your body when you eat sugar by using a CGM. It's an almost immediate visual telling you that you're inflicting damage on yourself. When you don't see it, you can pretend it's not really happening. When I saw that spike, I imagined my poor body trying to release all that insulin to remove sugar from my blood.

Great Book to Understand How Diet Impacts Blook Sugar and Health
Format: Hardcover
Life changing book that helped me understand how sugar and processed foods impacted my health. I verified the tips in this book with my own blood glucose monitor. The tips that she shared helped me reduce my glucose spikes and helped me enjoy a little snack from time to time.
