Sugar – Detrimental to Your Immune System Health

Posted on by

The ‘worst food ingredient for your immune system’— sugar. Most Americans consume between 19 and 25 teaspoons of added sugars daily.

Metabolic disorders, like obesity and diabetes, have surged in the U.S. over the past several decades. Experts believe that sugar consumption is the major cause of obesity and chronic diseases, such as type 2 diabetes.

According to many immunologist, having diabetes means your body is in a chronic low-grade inflammatory state, which stresses the body’s innate immune system and makes it slower to jump on pathogens, like COVID19, when they enter the body. Chronic inflammation is an unhealthy and abnormal immune reaction in the body and added sugars are a key diet component known to exacerbate this type of inflammation.

When it comes to your immune system, it important that you understand that what you eat does matter a lot. And no ingredient is more detrimental to your immune system and physical health than added sugar.

From marinara sauce to peanut butter, added sugar can be found in even the most unexpected products. According to the Food and Drug Administration (FDA), added sugars include sugars that are added during the processing of foods (such as sucrose or dextrose), foods packaged as sweeteners (such as table sugar), sugars from syrups and honey, and sugars from concentrated fruit or vegetable juices. They do not include naturally occurring sugars that are found in milk, fruits, and vegetables. The Daily Value for added sugars is 50 grams per day based on a 2,000 calorie daily diet. For most Americans, the main sources of added sugars are sugar-sweetened beverages, baked goods, desserts, and sweets.

The American Heart Association (AHA) states individuals should limit their sugar intake to six to nine teaspoons each day, which is roughly the same amount of sugar in a single can of sugary soda: eight teaspoons.

Sugar is not just bad for your teeth. Too much sugar can contribute to chronic diseases, can affect the pH levels within the body, and can impact heart health and brain health. Basically, sugar can affect the health of both your mind and body.

In the US, added sugars account for up to 17% of the total calorie intake of adults and up to 14% for children, according to AHA. The 2020-2025 Dietary Guidelines for Americans recommend that you limit your added sugars consumption to 10% of total calories, making the current average consumption by Americans significantly higher than recommended.

Eliminating excess added sugar from your diet can not only help end this cycle of increasing metabolic disorders, but it can reverse it completely. Dialing back your sugar consumption is one of the most effective ways to improve your immune system and your overall health.

Preventative care, especially when it comes to an insidious disease like diabetes, it is recommended that the first step you take in your nutrition journey is to ask your health care provider to perform a fasting hemogoblin A1c test, even if your fasting blood glucose is normal.

Hemogoblin A1c tests measure average blood sugar over the previous three months, so even if your blood sugar is normal the day you see your doctor, the test can catch underlying issues.

According to Dr. Heather Moday, a board-certified allergist, immunologist and functional medicine physician, once you have an idea of where you stand on the blood sugar spectrum, you can take the steps below for better health:

  1. Cut back on added sugars. – This means eliminating candy, soda, cake and those seasonal flavored lattes from your diet. These foods and drinks don’t provide any nutritional value, and they contain massive amounts of sugar.
  2. Read the labels. – It is essential to check the amount of added sugar in every item in your pantry. The average American takes in about 17 teaspoons (71 grams) of added sugar a day, but the American Heart Association recommends no more than six teaspoons (25 grams) of added sugar a day for women, and nine teaspoons (36 grams) for men.
  3. Eat more fiber. – If sugar is bad, then fiber is the good. Fiber not only keeps your digestion regular, it also helps slow the absorption of sugar into your bloodstream, which protects you from sugar spikes. Lack of fiber is another reason why sodas, fruit juices and sugared coffee drinks are so detrimental to your health. They contain a ton of sugar and none of the blood-sugar-protecting fiber that fresh whole plant-based foods have. The best high-fiber foods are black beans and lentils, steel-cut oats, avocados, buckwheat, pears, raspberries, barley and flaxseeds.
  4. Chose nutrients over calories. – Instead of worrying about cutting calories, focus on adding more nutrient-dense foods to your diet, with lots of proteins and healthy fats. You don’t need to go low-carb, just choose the “right” carbs. In fact, eating carbs in the form of vegetables, beans, whole fruits, and nuts and seeds — all mineral- and vitamin-rich foods — is a great way to keep those hunger pangs at bay.

Sugar does occur naturally in all foods that contain carbohydrates, such as fruits and vegetables, grains, and dairy. Consuming whole foods that contain natural sugar is okay, according to Harvard Medical School. Plant foods also have high amounts of fiber, essential minerals, and antioxidants, and dairy foods contain protein and calcium. Since your body digests these foods slowly, the sugar in them offers a steady supply of energy to your cells.

However, problems do occur when you consume too much added sugar — the sugar that food manufacturers add to products to increase flavor or extend shelf life. “Excess sugar’s impact on obesity and diabetes is well documented, but one area that may surprise many men is how their taste for sugar can have a serious impact on their heart health,” says Dr. Frank Hu, professor of nutrition at the Harvard T.H. Chan School of Public Health.

Bottomline is that too much added sugar can be one of the greatest threats to cardiovascular disease and metabolic health. And, your consumption of added sugar must be drastically reduced or eliminated from your diet to improve both your cardiovascular and metabolic health.

The goal isn’t to completely eliminate dessert or sweets from your life, but to bring your added sugar intake into a healthier range.
