How many processed meats, sugary drinks, and foods containing trans fatty acids are safe to eat? According to a new analysis, not very much.

The paper, published in Nature Medicine, found that consuming even less than a strip of bacon or a can of soda per day was linked to a higher risk of type 2 diabetes, colon cancer, or ischemic heart disease. Several studies suggest that processed meats, sugar-sweetened beverages, and trans fats contribute to chronic disease, but few have investigated how much of these substances is safe to consume.

The researchers determined that minimizing your intake of each of these food groups can significantly reduce your risk of life-threatening illness. “It is important to not eat these types of foods regularly, and certainly not daily,” McKale Montgomery, PhD, RD, LD, a registered dietitian and assistant professor of nutritional sciences at Texas Christian University, told Health. To assess how much these items contribute to disease risk, researchers evaluated over 60 studies that previously investigated the relationship between the three food categories and a person’s risk of type 2 diabetes, colorectal cancer, and ischemic heart disease. A higher intake of each group was consistently linked to a significantly increased risk of chronic disease.

More specifically, consuming very little amounts of processed foods and drinks upped the risk, and the more you eat, the greater your risk. When it came to processed meat, consuming as little as .6 grams to 57 grams (about five slices of bacon) a day was associated with an 11% and 7% greater risk of type 2 diabetes and colorectal cancer, respectively. Eating 50 grams a day (roughly one hot dog) was linked to a 30% higher risk of type 2 diabetes and 26% increased chances of colon cancer.

Consuming between 1.5 grams and 390 grams of sugar-sweetened drinks a day (about a 12-ounce soda) was linked to an 8% higher risk of type 2 diabetes and a slightly heightened risk of ischemic heart disease.

Meanwhile, trans fats comprising 0.25 to 2.56% of daily calories was associated with a 3% greater risk of ischemic heart disease.
