Is there such a thing as a longevity diet? Increasingly, studies suggest the answer is yes.
Around the world, certain groups of people enjoy exceptionally long lives. Consider the lucky people of Okinawa. These Pacific Islanders have an average life expectancy of more than 81 years, compared to 78 in the United States and a worldwide average of just 67. Closer to home, members of the Seventh Day Adventists, who typically eat vegetarian diets, outlive their neighbors by four to seven years on average.
Those first strands of gray hair are a sign of the inevitable. We’re getting older and our bodies are changing. We may grow a little rounder around the waistline, or wake in the night, or feel a little stiffer in the morning. Yet while we adapt to new realities, we shouldn’t discount every symptom as just further evidence of aging.
How do you know when to ignore your body’s lapses or when to seek medical advice? What’s normal aging, and what’s not?
“Aging, in and of itself, is a subtle, quiet process,”...
The residents of the San Blas islands off the coast of Panama very rarely suffer from high blood pressure and heart disease. Indeed, research shows that their rate of heart disease is only nine per 100,000 people, compared to 83 per 100,000 among nearby Panamanians on the mainland.
What makes these groups so fortunate? A growing body of evidence suggests that diet is one of the important contributors to longevity and healthy living. Here’s what’s on the menu of people who enjoy long and healthy lives.
Foods for a Healthy Heart
Most of us know to go easy on saturated fat, the kind found in meat and high-fat dairy products. Saturated fats have been shown to raise blood cholesterol levels into the danger zone. Just as important is what you should be eating. For heart health and longevity, you should eat:
Plenty of fruits and vegetables: Packed with fiber and nutrients, fruits and vegetables are also relatively low in calories. Studies consistently show that diets plentiful in fruits and vegetables help people maintain a healthy weight and protect against cardiovascular disease.
Whole grains: Like fruits and vegetables, whole grains pack a lot of nutrition into a low-calorie package. Grains like oats and barley are also rich in a long list of disease-fighting compounds.
In 2009, researchers at the University of Texas Health Sciences Center in Houston reported that study participants whose diets included plenty of whole grains and fruit cut their heart disease risk by almost half compared to those whose diets favored meat and fatty foods. Findings from more than 161,000 nurses enrolled in the Nurses’ Health Study also show that whole grains protect against type 2 diabetes, a disease that increases the danger of heart disease.
