Why is Sugar Toxic?

0 16 June 2017

shutterstock_87679807While humanity struggled for generations to get enough calories to stay alive, in the United States we now struggle to manage too many calories and must learn to eat in healthful balance. Perhaps the most devastating calories in our modern diet come from sugar.

What Makes Sugar Toxic?

The term sugar refers to a group of carbohydrate molecules consisting of carbon, hydrogen, and oxygen – the most relevant type, sucrose, is comprised of glucose and fructose stuck together into a single molecule. Glucose and fructose are metabolized in different ways in the body and are both harmful. Glucose raises the blood sugar abruptly, causing a spike in insulin production, which causes the body to store fat. Fructose is metabolized differently, and although it doesn’t increase the blood sugar as abruptly as glucose, it is much better at causing the deposition of fat into the liver, which can scar the liver and lead to cirrhosis. High-fructose corn syrup (HFCS), which has gotten the lion’s share of bad press of late, is actually quite similar to sucrose – whereas sucrose is 50% each glucose and

Living healthfully requires us to monitor our diets, exercise appropriately, and reduce our exposure to toxins like cigarette smoke and environmental pollutants. But what can we do to keep our skin looking healthy beyond protecting it from excess sun damage? Collagen is the body’s main structural protein. Collagen makes up 70% of skin and gives skin both strength and elasticity. But collagen production begins decreasing at age 18. By the age of 40, the decrease is about 1% per year. For women, the decline equates to a loss of 7% of skin thickness every 10 years. Following menopause, the decline in thickness accelerates to as much as 1.13% annually, while skin elasticity degrades 0.55% per year. Therefore, as we age our skin gets thinner and loses elasticity, making us look older. There are many techniques to improve the quality and appearance of the skin, typically working to increase skin collagen content, thickness, elasticity and hydration.

  Denver-AprilModern humans have become so disconnected from natural light cycles that we routinely struggle to get adequate sleep as we age. While we can’t be sure that our ancestors battled with insomnia, we do know that many adults over 40 have difficulty getting quality on a regular basis. Life stress, worry, unhealthy habits, and hormonal deficiencies can leave many of us wide awake, staring into the darkness wishing for a peaceful night’s rest. Stages of Sleep There are five stages of sleep. Getting into them can be a challenge for many, and coming out of them rapidly can be extremely disorienting. Stage 1, or Light Sleep: In this stage of sleep you may jerk away as your eyes and muscles slow down at the end of the day. Those who struggle with Restless Leg Syndrome often feel it in Stage 1. Stage 2: Brain waves begin to slow, though bursts of rapid waves can occur. The brain is headed into deep sleep. Stage 3 & 4: Deep sleep starts in stage 3, when the brain slows even further and Delta waves appear. Once stage 4 is reached, nearly all brain waves produced are

Denver3:6Introduction No matter how hard we try, we can still be in danger of consuming herbicides and pesticides that can harm our health. Produce can be particularly worrisome, because it seems even an organic diet can lead to some chemical exposure, depending on the certifying authority. GMO Contamination GMO (genetically modified organism)-crop test fields are often grown near non-GMO product fields. This can lead to cross-contamination of healthy plants with genetically modified plants that should not be ingested by humans or the animals we eat. Poor handling of GMO seeds may be at fault. However, even the most careful researchers cannot guard against every heavy rain or strong wind gust. For example, genetically modified canola seeds, supposedly grown in closed testing conditions, have contaminated non-GMO canola crops. Unless you know where the seeds are grown, you cannot be sure the canola oil you buy is strictly non-GMO. Flesh Contamination For those who eat meat, the risk is even higher. Genetically modified corn is a common component of animal feed across the United Stat

Denver-2.6.17Introduction Heart disease is the number one cause of death in the United States in both men and women. Per The Centers for Disease Control, heart disease kills over 600,000 people every year, and was responsible for 25% of all deaths in the United States in 2015. Risk Factors While there are genetic risk factors for heart disease, many of the conditions that increase your risk of heart attack are completely within your control. Being overweight, eating an unhealthy diet, not exercising, smoking and excess alcohol intake can severely impact your heart’s ability to carry you into old age. Exercise to Prevent Heart Disease Any exercise that elevates your pulse is a great way to strengthen your heart. If you’re just starting out on an exercise program, make sure you: 1) realize that you may not like exercise at the beginning, but commit to doing it at least 4-5 days per week, and be confident that as you remain consistent over time, it will become a joy 2) warm-up before your workout and stretch and cool down afterwards 3) find a workout buddy if you’r

denver12-7Most of us will have the privilege of aging. Getting older is a fact of life, and all the Botox and surgery in the world won’t stop the process, but there are lifestyle options which help stave off the aging process and allow us to enjoy our “golden years.” Age management medicine is the medical discipline that focuses on helping you to stay healthy for as long as possible. It is never too early to develop this mindset, and everyone over the age of 40 should consider preparing their physical health as well as their financial health for their retirement years. Invest in your health now: As we age we need to make allowances for the extra stress on our organs, joints and muscles. Diet and exercise are both vital components of a long and healthy life and it is necessary to adjust the way you eat and exercise as you advance in years. Women especially have a slower metabolism after menopause and find they need to eat to maintain a healthy weight. Exercise: Though cardio activities are crucial, they should be kept at the low-impact level to protect joints and ligaments. More attention should be

probioticsWhile it’s easy to consider your body a single being, in fact we are each a large combination of several organisms. The tiny organisms (microbes) that aid in our bodily functions including digestion are critically important to our health. If those microbes get out of balance, our health can be severely impacted.

1. Definition of microbiome The microbiome of a multi-celled organism such as a human is laden with microbes. In fact, while the human body is made up of millions of cells, we each contain more microbes than cells. Bacteria and some viruses are our constant companions, and while some can make us sick, many are good for us and critically important to our well-being. 2. Diseases that can be linked to dysfunction of the microbiome Radical changes to the microbiome can come from several sources including stress and antibiotics. While antibiotics certainly have their place and have been saving lives since the discovery of penicillin in 1928, over use of antibiotics can upset the balance of many bodily systems. Current research on microbiome health suggests

Cenegenics-DenverDementia describes a wide set of symptoms associated with a decline in memory and other cognitive abilities severe enough to affect your ability to perform daily activities. Alzheimer’s disease is the most common type of dementia, but several other types of dementia also exist. Fortunately, there are many things you can do to help prevent the development of dementia as you get older. Stimulate Your Brain: People who challenge their brains and continue to learn things throughout life are less likely to develop dementia. Learn a new language, musical instrument, or hobby. Playing strategy games and doing puzzles are also great ways to stimulate your brain. Varying your habits regularly creates new brain pathways. Try eating with your non-dominant hand or taking a different route on your way home from the store or work. Eat a Mediterranean Diet: Many epidemiological studies indicate that eating a Mediterranean diet dramatically reduces your risk of developing Alzheimer’s disease. Eating plenty of vegetables, legumes, nuts, seeds, fresh fish, healthy fruits, olive oil, and properly rai

There are so many advances in science and technology that promise longer and better lives, but how do we decide when to take advantage of them?  I believe that often times, people jump onto the latest promising supplement and forget to keep themselves grounded in the basics.  Rather than building a beautiful house on sand, it makes much more sense to build it on a strong foundation of stone.  What is that solid foundation when it comes to good health?      

  • Low glycemic, anti-inflammatory eating style – would you put canola oil in the engine of your Ferrari as its energy source? If not, why do you put the equivalent into your body for energy and expect it to run well?
  • Exercise – a combination of strength training and high-intensity interval training – there is no pill that will make you strong and give you endurance! If you want to be healthy at any age, you simply must exercise correctly on a regular basis.  Consistency is the key to success in this area.
  • Corrective
