Though ultra-processed foods may be safe, thousands are destroyed during processing. Heavy processing also strips fiber, altering digestion and the number of friendly bacteria in the gut. Dr. Michael Greger wants manufacturers to reconsider their ultraprocessing goals.
Processed foods
Many supermarket foods are highly processed. That means they have been altered in any way from their original state. These include pasteurizing, canning and freezing. These processes alter the nutritional quality of food. Many processed foods contain high amounts of calories, sodium and fat. These foods also usually contain chemical additives. However, this does not necessarily mean they are unhealthy, and minimal processing can be a part of a healthy diet.
Avoid eating processed foods when dining out. Fast-food restaurants tend to sell foods that are high in sugar and calories. You should eat healthier food such as soups, salads, or grilled chicken sandwiches. Even though it might be tempting to grab fast food, you should avoid eating processed meats like sausages, hot dogs, and bacon. You can also choose to eat prepared fruits and veggies that do not contain preservatives.
Sugar
Sugar can naturally be found in many foods. However sugar is sometimes added to foods in order increase their sweetness. Sugar can be white, brown, honey or corn syrup. While sugar can be harmful in small amounts it can pose a risk to your health. Refined sugar is very low in nutrients and is often used to enhance the flavour, texture, and colour of processed foods.
Although sugars have nutritional benefits, they can also be high in calories. Sugar may increase your desire to eat more. Experts recommend that you limit your intake of refined sugar to ten percent of your daily energy intake. However, if you find yourself constantly munching on sugary food, it may be a sign of unhealthy eating habits.
Salt
As an inorganic compound, sodium is used in foods as a natural preserver. It inhibits the growth and prolongs shelf life. In order to improve the texture and taste, salt is often added in processed foods. Studies have shown processed foods have higher amounts of sodium than fresh produce. The most sodium-rich food categories were processed meat, gravy or sauce, and milk products.
The human body loses sodium through perspiration, urine, and diarrhoea. The sodium content in blood drops when this happens, leading to hyponatremia. This can lead to muscle cramps and dizziness as well as shock. In extreme cases, the sodium levels may drop so low that a person may even fall into a coma.
Flavors
Food manufacturers often use flavorings to improve the taste of their products. Some flavors contain only one ingredient, while others have hundreds. However, most of these flavorings have been approved by the US Food and Drug Administration (FDA). Food manufacturers do not list all of their ingredients on the label because they don't want to divulge proprietary formulas.
Food flavors come in a variety of forms, including synthetic and natural. These flavors are often added to processed foods, and they have very little nutritional value. However, natural flavorings may provide some health benefits. In fact, adding strawberries to plain yogurt is not unhealthy. This is because real strawberries give our bodies the strawberry flavor as well as fiber.
Serving size
Although the serving size is based upon typical consumption, it's important to remember that this is an estimation. Packaged food serving sizes are not recommended and may not be suitable for all diets. A single scoop of ice cream has 500 calories and 29g of sugar.
According to a survey conducted by the International Food Information Council, nearly a third of Americans surveyed did not fully understand the concept of portion size. They misunderstood the terms serving size and portion size. Food and Drug Administration established a standardized serving size that is based upon the amount of food consumed in one meal. It is also found on some restaurant menus, cafeteria menus, school lunch menus and hospital cafeteria meals.
