Who doesn't like the taste of sugar?
The problem is that we can easily become addicted to it and consume so much that it can become detrimental to our health.
However, consider the copious amounts of added-sugar (with calories) consumed in soft and sports drinks, fruit juices, and almost all processed foods. Realize too that sugar is not only in the foods typically acknowledged as sweetened, but its presence also permeates many other processed foods. E.g. Prego spaghetti sauce lists sugar as its second highest ingredient content after tomatoes (containing ~ 2 ½ tsps. / half cup)
Sugar consumption has escalated over the decades
In 2011, the USDA estimated the average American consumed 12 teaspoons sugar /day. That's over 1 ½ tons of sugar in a lifetime!
However, intake of added-sugar (caloric sweeteners) between 1999 and 2008 has SUPPOSEDLY decreased significantly. A study by Welsh and colleagues concluded that added-sugar intake, although still higher than recommended, had reduced primarily because of a reduction in consumption of sweetened beverages (except energy drinks, which increased). Welsh, 2011), but read on . . .
Data from Centers for Disease Control and Prevention NHANES surveys and USDA Economic Research Service food disappearance records provided data for this graph in a 2017 article by academic researcher Dr. Stephan Guyenet, which shows added-sugar consumption on the decline as obesity increased.
This USDA data was altered. Robert Greer, a lawyer who writes about food politics responded to Guyenet in an article entitled "No, sugar consumption hasn't fallen" that the USDA had altered the data at the (documented) request of the sugar industry. "Around 2011, the USDA changed its methodolgy for determining how much sugar Americans consume, by revising its estimate of how much cane and beet sugar was "lost" (i.e. produced but not eaten) from 20% to 34%. The industry association argued that estimates should be even lower. " The result: a reported 14% reduction in average per capita sugar consumption in the U.S. from ~ 88 lbs / person to ~76lbs / person. Mr Greer concludes in an update to his article evaluating new more credible evidence, that sugar consumption may have fallen slightly off already sky-high levels since around 2000.
Since 2000, added-sugar (contains calories) has been replaced with no/low calorie non-nutritional sweeteners (NNS). Although NNS contain no or few calories, the artificial NNS have never-the-less been shown to cause weight gain and their consumption does correlate with obesity.
Do you think the U.S. has a weight or diabetes problem?
An estimated almost 1/3 of Americans aged 20 - 74 are now obese, an additional 1/3 are overweight. Obesity rate has doubled since 1975.
Ogden CL, Carroll MD, McDowell MA, Flegal KM. Obesity among adults in the United Statesâ€”No statistically significant change since 2003-2004. NCHS Data Brief No. 1. Hyattsville, MD: National Center for Health Statistics; 2007. p. 1-8
An estimated 1 out of 3 U.S. children are obese! This author is irritated that the U.S. Department of Family and Children will diligently investigate a claim brought by a teacher who thinks a child looks too thin and underfed, but it is not considered a possible abuse when a child is seen to be significantly overweight
Obesity is the number one reason why applicants fail to qualify for military service. A report by retired admirals and generals found that 27% potential young recruits (~15,000 /year) fail their entrance physicals due to being overweight and a whopping 75% of young people would not qualify to join the military for the same reason.
Report by Mission: Readiness, an organization made up of retired admirals and generals
Compare less than 3 cases of diabetes per 100,000 people in the U.S. in 1893 to today, with diabetes striking almost 8,000 out of every 100,000 people. i.e. 8.3% of the population!

Consuming too much added-sugar is one dietary factor involved in several adverse health consequences
Other health-detrimental dietary factors include: excessive fructose consumption and excessive carbohydrate intake.
Excess sugar has detrimental effects on hormones controlling blood sugar and appetite
Sugar decreases the receptor sensitivity for both INSULIN and LEPTIN - causing high blood sugar / INSULIN resistance (IR), which can lead to:
• High blood pressure and high cholesterol
• Heart disease
• Weight gain
• Premature aging
Sugar increases INSULIN for the purpose of removing sugar from the blood into cells where it can be metabolized.
▲ INSULIN works mainly at the level of most individual cells. INSULIN tells each cell whether to burn or store fat or sugar and whether to utilize produced energy for:
(i) Maintenance and repair - equates to increased longevity;
Or (ii) Reproduction
▲ Chronically high INSULIN levels reduce sensitivity of INSULIN receptors. This is referred to as INSULIN resistance (IR), with consequential high blood glucose levels and so called metabolic syndrome, increasing risk of such as type 2 diabetes, heart disease, obesity and premature aging
Sugar increases LEPTIN (the “satiety” hormone, produced by fat cells). At first sight, this may seem like a good thing, but read on . . .
▲ LEPTIN works at the level of the whole body of cells. It controls energy storage and utilization of the entire republic of cells, communicating with the brain as to whether the body has stored or burned enough energy, whether to be hungry and make more fat, whether it is a good time (nutritionally speaking) to reproduce or not, and whether to maintain/repair yourself.
▲ LEPTIN sends signals that:
(i) Reduce ▼ hunger,
(ii) Increase▲ fat burning
and (iii) Reduce▼ fat storage
▲ However, due to chronically high levels of LEPTIN, in almost all overweight and obese people their LEPTIN receptors have become resistant (even though they have excess LEPTIN), and the LEPTIN signal is not being “heard”- i .e. the body can no longer “hear”the messages telling it to stop eating and burning fat - and so it remains hungry and stores more fat.
LEPTIN - Weight Control Hormone
Sugar consumption triggers addiction process
Eating sugar triggers the brain to produce opioids initiating the addiction process. i.e. the brain becomes addicted to stimulating release of its own opioids in just the same way as partaking of morphine, heroin, cocaine, alcohol, cannabis and nicotine
Long-term stimulation of the brain's pleasure center (nucleus accumbus) drives the addiction process. On consumption of an addictive substance such as sugar, the pleasure centure receives a DOPAMINE signal and you sense pleasure. Receiving pleasure is in fact essential to your will to live, but you can overdo this need by chronically supplying the addictive substance . . . such that the prolonged DOPAMINE exposure causes the signal to weaken and you need more of the addictive substance to get the same effect. This is called TOLERANCE. If you stop providing the addictive substance you go into WITHDRAWAL .
TOLERANCE + WITHDRAWAL = ADDICTION
This biochemical force is not likely to be overcome with cognitive willpower, according to Dr. Robert Lustig, professor of pediatrics at the University of California, San Francisco, who has been a pioneer in understanding sugar metabolism.
It is speculated that high sugar diets also overstimulate the two sweet receptors on the tongue - which in turn may be over-stimulating the brain's reward signals
Sugar makes you fat
Over-consumption of sugar causes obesity. Today's level of added-sugar consumption (mostly sucrose and HFCS) is undoubtedly a major factor in the growing numbers of those who are obese.
Chronic overconsumption of sugar contributes to receptors become insensitive to the messages of INSULIN and LEPTIN. i.e. promotes weight gain
Body stores excess sugar (and other carbs) as fat. The body converts different forms of sugar into glucose, which it uses to provide energy, especially if you are active. If you consume more sugar than you are using, a limited amount is stored for later use in the liver and muscles, but when those small “storage bins” are full, sugar is converted to fat and stored where we can all see it!
Carrying excess weight around will increase your risk for deadly conditions. E.g. heart disease, kidney disease, and diabetes.
Today's obesity problem may be more a result of fructose replacing glucose consumption in mega amounts. Fructose consumption has increased significantly in the last 4 decades:
• HFCS has replaced 50% of U.S. sucrose consumption since the early 70's. SInce this time it should also be noted that caloric intakes of sugar, fats and carbohydrates have also increased
• Fructose is metabolized differently to glucose and places a significant burden on the liver . This can cause related health problems
• ~ 1/3 of fructose calories are stored as fat . Compare this to ~1/100 of glucose calories
• Fructose reduces postprandial INSULIN response. This can lead to INSULIN resistance and then metabolic syndrome/ T2 diabetes
