National Nutrition Month 2017: Are Half Of Your Grains Whole?

Recent studies focus on the benefits of whole grains in lowering risk of obesity, type 2 diabetes, cardiovascular diseases and other chronic conditions. But what types of carbohydrates should you choose for workouts and for keeping your energy high throughout the day?

Incorporating grains into a healthy lifestyle
Carbohydrates act as the primary fuel for your brain and muscles. Remember those pasta nights before the big game? The reason for the “carb load” was to increase your glycogen, or your stored carbohydrates, to be available as energy while you exercise. Fast-acting energy sources, such as refined grains, can provide quick energy before, during and after a game or workout. But what about energy over the course of the day, while you are at work or taking care of the kids? Throughout the day, active men and women should consume 6-8 ounces or servings of grains.

What kind of grains should I look for?
According to the Dietary Guidelines, at least half of your grains should be whole grains. Whole grains contain the entire kernel and provide dietary fiber, iron, B vitamins and phytochemicals. When shopping, look for whole grains as the first ingredient on the package. When eating out, look for menu items with whole grain pasta, brown rice, quinoa, oatmeal, whole wheat wraps, tortillas and other whole grains.

Bottom Line:
The health benefits of whole grains are more pronounced within the context of a healthy lifestyle. If you lead an active lifestyle, consider limiting refined grains to periods before, during or after a workout. The rest of your servings of carbohydrates should be focused on complex, whole grains.

National Nutrition Month 2017: Plant Power

If you follow food trends, you’ve surely noticed that plant-based foods, recipes and restaurants have been getting a larger share of the spotlight lately. Does this mean that more of us are becoming vegetarians? Should we be? Why more plants? Fruits, vegetables, whole grains, beans, peas, nuts and seeds are key features of some of the healthiest diets in the world. Plant based foods are a common theme in the Mediterranean Diet, the DASH Diet and most dietary guidelines. The balance of health promoting nutrients with moderate calories and less of the stuff we should be limiting make plant based foods an easy fit for most people. Looking beyond personal health, to the health of our planet, plant based foods tend to more sustainable and less taxing on the environment. What is a flexitarian? Or a pescatarian? With the expansion of plant foods on our plates has come an expansion of how we refer to the way we eat. Vegetarian still refers to people who don’t eat meat, fish or poultry, but the...

Are you a Healthy Shopper?

Does where you buy your food determine how healthy you are? A recent study suggests that there may be a link between the type of store where you do most of your food shopping and your weight and the health of your diet overall. Which stores were better? Some of the results were what you might expect. People who shopped often at convenience stores ate fewer fruits and vegetables. Convenience stores don’t tend to have large produce departments, so this makes sense. Fruits and vegetables were a bigger part of the diets of people who frequented supermarkets and specialty stores. Overall diet quality was highest in those who shopped at food co-ops. From a weight perspective, people who shopped at specialty stores and farmers markets tended to weigh less and people who shopped at food co-ops had smaller waists. Which comes first? Now the question is, do healthy people tend to shop at certain stores or do certain shopping habits make you healthier? This recent study isn’t able to say for sure...
