Certain dietary patterns and habits that have been linked to an increased risk of chronic diseases, which can ultimately lead to a shorter lifespan. Here are some examples:

1. Processed meats: Consuming large amounts of processed meats, such as bacon, sausages, and hot dogs, has been linked to an increased risk of heart disease, stroke, and cancer. 

2. Sugar-sweetened beverages: Drinking large amounts of sugar-sweetened beverages, such as soda and fruit juice, has been linked to an increased risk of obesity, type 2 diabetes, and heart disease. These drinks are also high in calories and can contribute to weight gain, which can negatively impact overall health.

3. Trans fats: Trans fats are a type of unsaturated fat that have been linked to an increased risk of heart disease and other chronic diseases. Trans fats are commonly found in processed foods, such as baked goods, snacks, and fried foods.

4. Refined carbohydrates: Refined carbohydrates, such as white bread, pasta, and rice, have been linked to an increased risk of obesity, type 2 diabetes, and other chronic diseases. These foods are often high in calories and low in nutrients.

5. Excessive alcohol consumption: Consuming large amounts of alcohol has been linked to an increased risk of liver disease, cancer, and other chronic diseases. Alcohol can also contribute to weight gain and other negative health outcomes.

Overall, a diet high in processed and refined foods, sugar-sweetened beverages, trans fats, and alcohol, and low in fruits, vegetables, whole grains, and grass-fed and lean protein sources, has been associated with an increased risk of chronic diseases and a shorter lifespan.
