The truth about dietary fat



For years, experts recommended low-fat diets as a way to lower cholesterol and heart disease risk. Today, we know that low-fat isn't the way to go after all. A healthy diet includes plenty of "good-for-you" fats -- and limits the unhealthy ones. Current dietary guidelines recommend that you get 20% to 35% of your daily calories from fat. Even more may be fine, if you follow these simple guidelines.

Favor the "good" fats.
The best sources of healthy fats are oily, cold-water fish, such as salmon and tuna; plant sources such as avocados and nuts; and vegetable oils, such as olive, canola, soybean, and cottonseed oils. These fats promote heart health because they lower cholesterol levels - and they may even fight chronic inflammation, which may contribute to heart disease. It's okay to get up to 35% of your daily calories from fat - as long as most of it comes from sources like these.

Limit saturated fats
Typical sources of saturated fat include animal products, such as red meat, whole-fat dairy products, and eggs, and also a few vegetable oils, such as palm oil, coconut oil, and cocoa butter. Saturated fat can increase your levels of "bad" LDL cholesterol. But it has some benefits, too - it lowers triglycerides and nudges up levels of "good" HDL cholesterol.

The role of saturated fat in heart disease is currently under debate. For now, it's best to limit your intake of saturated-fat rich foods.

The lowdown on glycemic index and glycemic load

What are the facts about the glycemic load of foods? If you have diabetes, you probably know you need to monitor your carbohydrate intake. But different carbohydrate-containing foods affect blood sugar differently, and these effects can be quantified by measures known as the glycemic index and glycemic load. You might even have been advised to use these numbers to help plan your diet. But what do these numbers really mean---and just how useful are they? Glycemic index vs. glycemic load The glycemic index (GI) assigns a numeric score to a food based on how drastically it makes your blood sugar rise. Foods are ranked on a scale of 10 to 100. The lower of a food's glycemic index, the slower blood sugar rises after eating that food. In general, the more processed a food is, the higher its GI, and the more fiber or fat in a food, the lower it's GI. But the glycemic index tells just part of the story. What it doesn't tell you is how high your blood sugar could go when you

Making friends in your 50s and beyond isn't nearly as easy as it was when you were young. School and work provide the perfect opportunities to meet and interact with new people.

Do you like to knit, paint, play bridge, or sing? Join a knitting club, take a painting class, join a bridge group, or audition for a chorus or musical in your area.
