Smoking is the single largest lifestyle factor reducing life expectancy, with smokers losing approximately 10 years of life compared to non-smokers. Other major contributors to reduced lifespan include high-calorie/processed diets, obesity, excessive alcohol consumption, and sedentary lifestyles, which together drive chronic diseases like cardiovascular disease and cancer.
A new report from the Institute for Clinical Evaluative Sciences and Public Health Ontario concluded that smoking, excess alcohol consumption, poor diet, sedentary lifestyle and stress can all collectively decrease your lifespan by seven and a half years.
A peanut butter and jelly (PB&J) sandwich adds about 33 minutes to your healthy life expectancy, according to a University of Michigan study that developed a Health Nutritional Index (HENI) to quantify the minutes gained or lost from eating different foods. This benefit comes from its mix of healthy fats, protein, and antioxidants, especially when using whole-grain bread and lower-sugar spreads, contrasting with foods like hot dogs that take minutes off your life.
Together, injuries (drug overdose, firearm-related deaths, motor vehicle accidents, homicide), circulatory diseases, and mental disorders/nervous system diseases (including Alzheimer's disease) account for 86% and 67% of American men's and women's life expectancy shortfall, respectively.
For longevity, longevity expert Valter Longo suggests avoiding the "poisonous 5 Ps": Pizza, Pasta, Protein, Potatoes, and Pane (bread), particularly in refined forms, as these contribute to inflammation, blood sugar spikes, and obesity, hindering healthspan and lifespan, especially in diets like the modern Italian one that deviates from the traditional Mediterranean diet.
What food can you survive on forever? No, it is not possible to survive on a single food forever without developing nutritional deficiencies. While some foods offer a broad range of nutrients, none provide all the essential macronutrients, vitamins, and minerals needed to sustain long-term health.
Previous research from the CALERIE trial has found that calorie restriction can slow the pace of aging in adults by 2 to 3 percent — enough to reduce the risk of death by 10 to 15 percent. Other research indicates that cutting calories can decrease DNA damage and improve heart health, sleep and sexual function.
Alcohol: Drinking too much alcohol can dehydrate and damage your skin over time, leading to signs of premature aging. Poor sleep: Studies show that low quality (or not enough) sleep makes your cells age faster. Stress: When you're stressed, your brain pumps out cortisol, a stress hormone.
The number one worst thing for heart health is widely considered to be smoking tobacco, including cigarettes, cigars, and vaping, as it significantly damages blood vessels, raises blood pressure, reduces good cholesterol, and increases the risk of blood clots, leading to heart attacks and strokes. Other major culprits include a sedentary lifestyle, poor diet (processed foods, sugar, unhealthy fats), excessive alcohol, chronic stress, and carrying excess belly fat, all of which contribute to heart disease.
The "3-3-3 Rule" for habits is a guideline suggesting it takes 3 days to start, 3 weeks to build consistency, and 3 months (about 90 days) to solidify a new behavior into a permanent habit or lifestyle change, acting as a psychological tool to break down overwhelming goals into manageable phases. It helps you push through initial resistance (days), establish a routine (weeks), and integrate it fully (months), though real change happens through consistent identity-based action, not just the numbers.
Best survival rates were found among those who slept seven hours a night. A group sleeping eight hours was 12% more likely to die within the six year period than those sleeping seven hours, other factors being equal. Even those with as little as five hours lived longer than those with eight hours or more nightly.
While it is no surprise that a lifetime of smoking, heavy drinking, and physical inactivity is a recipe for ill health later in life. Now, a new study finds that these habits can result in health issues as young as the age of 36, including their influence on mental health.
The 80/20 rule diet is a flexible eating plan where you focus on nutritious, whole foods (fruits, veggies, lean proteins, whole grains) for 80% of your diet, allowing for less healthy, indulgent foods (treats, desserts) for the remaining 20%. It's sustainable because it emphasizes consistency over perfection, prevents feelings of deprivation, and promotes a healthy relationship with food, making it easier to stick with long-term for weight management and overall health.
The 2-2-2 food rule is a simple guideline for food safety and reducing waste with leftovers: get cooked food into the fridge within 2 hours, eat it within 2 days, and if freezing, store it for up to 2 months for best quality, preventing harmful bacteria growth in the "Danger Zone" (40°F-140°F). This rule helps you manage perishable items, from big roasts to batch-cooked soups, ensuring they're safe and delicious.
The researchers calculated that people who adhered to five things—drink no more than one glass of alcohol per day (two for men), maintain a healthy body weight, eat a high-quality diet, abstain from smoking, and exercise at a moderate-to-vigorous pace (think a brisk walk, at least) for 30 minutes or more a day—had a ...
