Processed Foods Lead to Cancer

French studies: every 10% of ultra-processed food in the diet raises the risk of early death by 14% and cancer incidence by 12%.

Processed foods lead to cancer and early death

Fighting weight gain and obesity is a common and costly public health problem that leads to an increased risk of cardiovascular disease, type 2 diabetes, and cancer.

According to the latest data, 18.5% of American children and nearly 40% of adults suffer from obesity. This is a significant increase compared with 1999/2000 figures, when just under 14% of children and 30.5% of adults were affected. Studies have linked the increase in waist circumference to processed foods, sugary drinks, and a high-carbohydrate diet.

Dietary changes drive the obesity epidemic

Over the past 200 years, sugar consumption has risen from 2 to 152 pounds per year. Although Americans are advised to get only 10% of their calories from sugar, the average intake is 42.5 teaspoons per day, while the recommended limit is about 13.

Sugary drinks and fruit juices are particularly harmful: each daily serving raises a child's risk of developing obesity by 60%. A refined high-carbohydrate diet increases the risk of lung cancer by as much as 49%.

Between 1970 and 2009, daily calorie intake grew by an average of 425, or 20%. This growth is largely driven by increased consumption of sugar and processed foods.

When ultra-processed food becomes the norm

Ultra-processed products at the far end of the "significantly altered" spectrum make up 60% of the American diet. The developed world as a whole consumes significant amounts of processed foods. It has been estimated that 40% of healthcare spending in America is attributable to diseases directly linked to excessive sugar consumption.

Defining ultra-processed food

As a rule, ultra-processed foods can be identified as products that meet one or more of the following conditions:

  • Ingredients that are not traditionally used in cooking.
  • Unnaturally high amounts of sugar, salt, processed industrial oils, and harmful fats.
  • Artificial flavorings, colorings, sweeteners, and other additives.
  • Technological modifications: carbonation, fortification, bulking, emulsifiers, humectants.
  • Preservatives and chemicals that give an unnaturally long shelf life.
  • Genetically modified ingredients.

Processed foods linked to early death

A recent study of more than 44,000 people followed over seven years warns that ultra-processed foods increase the risk of early death. The French team found that for every 10% increase in the share of such products in the diet, the risk of death rose by 14%.

Another French study of 105,000 participants showed that a 10% increase in ultra-processed food intake raised the cancer incidence rate by 12%. The risk of developing breast cancer rose by 11% for every 10% increase in ultra-processed food intake.

What to do

  • Focus on raw, fresh foods and avoid processed ones.
  • Strictly limit carbohydrates from refined sugar, fructose, and processed grains.
  • Increase your intake of healthy fats.
  • Eat unlimited amounts of non-starchy vegetables.
  • Limit protein to less than 0.5 grams per pound of lean body mass.
  • Replace sugary drinks and other sweetened beverages with clean filtered water.
  • When shopping, walk the perimeter of the store — that's where most whole foods are located.
