Here Is How Sugar Addiction May Lead To Depression

All of us feel a little blue at some point. When we are feeling a little extra down, though, a lot of us crave eating something sweet, don’t we? Having that candy, a bar of chocolate, an ice cream, or maybe even a little muffin does lift our spirits momentarily. While eating these sweets occasionally is fine, having too much sugar can have long-term implications on mood disorders.

Complex carbohydrates like fruits, vegetables, and grains have natural sugars that are healthy. However, it is also present in refined food items, such as cakes, pasta, baked goods, candy, and bread. While regular intake of sugar can lead to a variety of health issues, it has also been found to increase your risk of depression and mood disorders. Since the brain depends on an even supply of glucose, sugar’s involvement in aiding anxiety and depression isn’t altogether surprising.
Here we list some of the possible connections between sugar and depression.

1. The link between depression and refined carbohydrates

A study by Columbia Medical Center in 2015 noted that a diet high in refined carbohydrates may become a risk for depression, especially in postmenopausal women. Highly refined carbohydrates include items like white bread/pasta, white rice, crackers, cookies, and soda. These products increase blood sugar and may set off a hormonal response in the body to reduce blood sugar levels. These responses may also lead to changes in mood and cause fatigue.
Researchers also observed that a diet with a higher intake of dietary fiber, whole grains, vegetables, and fruit can lower the risk of depression for middle-age people. Thus, a healthy diet that is low in refined carbohydrates could well be a preventive measure for depressive episodes.

2. Sugar can be more addictive than cocaine

In a study that was published in the British Journal of Sports Medicine, the authors mentioned that sugar could act as a gateway to alcohol and other addictive substances. They added that sugar is refined from plants to produce pure white crystals, much like stimulants, such as cocaine and opium. According to the researchers, this process significantly adds to sugar’s addictive properties.
“Consuming sugar produces effects similar to that of cocaine, altering mood, possibly through its ability to induce reward and pleasure, leading to the seeking out of sugar,” the study states.
Cassie Bjork, R.D., L.D., founder of Healthy Simple Life, further illustrates the point: “Sugar activates the opiate receptors in our brain and affects the reward center, which leads to compulsive behavior, despite the negative consequences like weight gain, headaches, hormone imbalances, and more.”

3. Too much sugar could increase depression risk in men

Recent research has indicated that men who consume more sugar run an increased risk of depression. Researchers from University College London (UCL) studied the sugar in the diet and common mental health problems of a large group of men and women. They discovered a greater link between consuming higher levels of sugar and depression in men. The study claims that men who consumed more than 67g of sugar a day had a 23% increased risk of suffering from a common mental disorder after 5 years than those who had less than 39.5g of sugar.
“This study is important because it is the first to be able to show that an increase in risk of about a quarter in common mental disorders – mostly mild anxiety and depression – in men who eat the most sugar cannot be explained by those who were already anxious or depressed using sugar as a form of comfort,” says Rob Howard, professor of old age psychiatry at UCL.
However, more studies are needed to confirm this theory.

4. Frequent consumption of commercial baked goods can increase the risk of depression

Various commercially prepared baked goods like muffins, doughnuts, croissants, and pastries may taste incredibly good but aren’t good for your mental health according to Spanish researchers. They found that participants who ate the most baked goods had a 38% higher risk of depression compared to those individuals who ate less baked goods.
Too much consumption of commercially prepared baked goods was never good for health anyway. Now that they may have a detrimental effect on depression risk, it is important to be cautious before having these products regularly. 

5. Depression, sugar, and inflammation

A diet that is high in refined carbs may promote inflammation. In fact, researchers at the University of Kansas found that inflammation was an essential physiological effect of dietary sugar intake.

“Added sugars have a profound effect on inflammatory processes within the body and brain, and inflammation may serve as a key mediator of sugar-induced depression onset,” says one of the researchers from the team.

Interestingly, many symptoms of inflammation are also common with depression, e.g. loss of appetite, changes in sleep patterns and heightened perceptions of pain. Furthermore, some studies have reported that inhibition of inflammatory pathways can improve mood. Thus, depression may very well be an elemental sign of inflammation-related issues. 

6. Sugar causes a serotonin crash

Serotonin or 5-hydroxytryptamine is a chemical produced by nerve cells and is found in three parts of the body — the brain, the lining of the digestive tract, and in blood platelets. It is a vital neurotransmitter known as the “happiness molecule” because of its key role in maintaining a positive mood.

When we are feeling low, we often tend to go for sugar and other processed carbs. This generally gives us a serotonin boost or basically helps lift our mood. However, that feeling is short-lived. For instance, candy and sweets, which are simple carbohydrates, will have the greatest impact on your serotonin, but that effect will only last one to two hours before it comes crashing down. This will eventually make you feel worse. Thus, reduced quantities or activity of serotonin in the brain may influence depression.

Do note that the above-mentioned theories are hypotheses and several more studies still need to be conducted to understand how sugar contributes to depression. That being said, it's possible to suggest that high-dose sugar intake can unsettle various metabolic, inflammatory, and neurobiological processes and many of these effects are of particular significance to the onset of depressive illness. Whatever may be the case, it is always good to be careful about your sugar intake for a healthy lifestyle.

New study questions link between saturated fats, heart disease

Many of us have long been told that saturated fat, the type found in meat, butter and cheese, causes heart disease. But a large and exhaustive new analysis by a team of international scientists found no evidence that eating saturated fat increased heart attacks and other cardiac events.

The new findings are part of a growing body of research that has challenged the accepted wisdom that saturated fat is inherently bad for you and will continue the debate about what foods are best to eat.

For decades, health officials have urged the public to avoid saturated fat as much as possible, saying it should be replaced with the unsaturated fats in foods like nuts, fish, seeds and vegetable oils.

But the new research, published on Monday in the journal Annals of Internal Medicine, did not find that people who ate higher levels of saturated fat had more heart disease than those who ate less. Nor did it find less disease in those eating higher amounts of unsaturated fat, including monounsaturated fat like olive oil or polyunsaturated fat like corn oil.

“My take on this would be that it’s not saturated fat that we should worry about” in our diets, said Dr. Rajiv Chowdhury, the lead author of the new study and a cardiovascular epidemiologist in the department of public health and primary care at Cambridge University.

But Dr Frank Hu, a professor of nutrition and epidemiology at the Harvard School of Public Health, said the findings should not be taken as “a green light” to eat more steak, butter and other foods rich in saturated fat. He said that looking at individual fats and other nutrient groups in isolation could be misleading, because when people cut down on fats they tend to eat more bread, cold cereal and other refined carbohydrates that can also be bad for cardiovascular health.

“The single macronutrient approach is outdated,” said Dr Hu, who was not involved in the study. “I think future dietary guidelines will put more and more emphasis on real food rather than giving an absolute upper limit or cut-off point for certain macronutrients.”

He said people should try to  eat foods that are typical of the Mediterranean diet, like nuts, fish, avocado, high-fibre grains and olive oil. A large clinical trial last year, which was not included in the current analysis, found that a Mediterranean diet with more nuts and extra virgin olive oil reduced heart attacks and strokes when compared with a lower fat diet with more starches.

Alice H Lichtenstein, a nutritional biochemist at Tufts University, agreed that “it would be unfortunate if these results were interpreted to suggest that people can go back to eating butter and cheese with abandon,” citing evidence that replacing saturated fat with foods that are high in polyunsaturated fats — instead of simply eating more carbohydrates — reduces cardiovascular risk.

Dr Lichtenstein, who was not involved in the latest study, was the lead author of the American Heart Association’s dietary guidelines, which recommend that people restrict saturated fat to as little as 5 per cent of their daily calories, or roughly two tablespoons of butter or two ounces of Cheddar cheese for the typical person eating about 2,000 calories a day. The heart association states that restricting saturated fat and eating more unsaturated fat, beans and vegetables can protect against heart disease by lowering low-density lipoprotein or so-called bad cholesterol.

In the new research, Dr Chowdhury and his colleagues sought to evaluate the best evidence to date, drawing on nearly 80 studies involving more than a half million people. They looked not only at what people reportedly ate, but at more objective measures such as the composition of fatty acids in their bloodstreams and in their fat tissue. The scientists also reviewed evidence from 27 randomised controlled trials — the gold standard in scientific research — that assessed whether taking polyunsaturated fat supplements like fish oil promoted heart health.

The researchers did find a link between trans fats, the now widely maligned partially hydrogenated oils that had long been added to processed foods, and heart disease. But they found no evidence of dangers from saturated fat, or benefits from other kinds of fats.

The primary reason saturated fat has historically had a bad reputation is that it increases low-density lipoprotein cholesterol, or LDL, the kind that raises the risk for heart attacks. But the relationship between saturated fat and LDL is complex, said Dr. Chowdhury. In addition to raising LDL cholesterol, saturated fat also increases high-density lipoprotein, or HDL, the so-called good cholesterol. And the LDL that it raises is a subtype of big, fluffy particles that are generally benign. Doctors refer to a preponderance of these particles as LDL pattern A.

The smallest and densest form of LDL is more dangerous. These particles are easily oxidized and are more likely to set off inflammation and contribute to the buildup of artery-narrowing plaque. An LDL profile that consists mostly of these particles, known as pattern B, usually coincides with high triglycerides and low levels of HDL, both risk factors for heart attacks and stroke.

The smaller, more artery-clogging particles are increased not by saturated fat, but by sugary foods and an excess of carbohydrates, Dr Chowdhury said. “It’s the high carbohydrate or sugary diet that should be the focus of dietary guidelines,” he said. “If anything is driving your low-density lipoproteins in a more adverse way, it’s carbohydrates.”

While the new research showed no relationship overall between saturated or polyunsaturated fat intake and cardiac events, there are numerous unique fatty acids within these two groups, and there was some indication that they are not all equal.

When the researchers looked at fatty acids in the bloodstream, for example, they found that margaric acid, a saturated fat in milk and dairy products, was associated with lower cardiovascular risk. Two types of omega-3 fatty acids, the polyunsaturated fats found in fish, were also protective. But a number of the omega-6 polyunsaturated fatty acids, commonly found in vegetable oils and processed foods, may pose risks, the findings suggested.

The researchers then looked at data from the randomised trials to see if taking supplements like fish oil produced any cardiovascular benefits. It did not.

But Dr Chowdhury said there might be a good explanation for this discrepancy. The supplement trials mostly involved people who had pre-existing heart disease or were at high risk of developing it , while the other studies involved generally healthy populations.

So it is possible that the benefits of omega-3 fatty acids lie in preventing heart disease, rather than treating or reversing it. At least two large clinical trials designed to see if this is the case are currently underway.
