Dietary Fiber: The Basics
Fiber is an essential component of our diets, yet most Americans don’t eat enough, with usual intakes of approximately half the daily recommendation.1

The Science behind the PointsPlus® Program
Our science-based lifetyle modification program is based on 4 pillars: Diet, physical activity, positive thinking and support.

What is “Natural”?
The term "natural" can be found all over the marketplace these days but what does the word really mean?

Salt: Why Less is More for this Essential Nutrient
The evidence is clear that the higher the intake of salt and other sodium-containing foods, the higher the blood pressure.

Vitamin D: Emerging Role in Health
Vitamin D is well known for its role in developing and maintaining strong bones, but new research suggests that it may also play an expanded role in promoting health and preventing disease. At the same time, many people do not get enough.

Vegetarian Diets and Weight
It’s clear that creating a caloric deficit is the only way to lose weight, but how do vegetarian diets rank compared to other diets when it comes to weight loss? Further, is there typically a difference in weight between vegetarians and non-vegetarians?

Vegetarian Diets
Many people choose to follow some form of a vegetarian diet, often saying that it’s healthier. But is there compelling evidence that this is the case?

Water versus Fluid: What Counts, What Doesn’t
In terms of hydration, the words water and fluid are often used interchangeably. However, other liquids, like coffee and fruit juice, are also classified as fluids. Is there scientific evidence to support that these beverages can be included towards meeting fluid recommendations?

Alcohol, Health and Weight
While the relationship between alcohol and general health is relatively clear, the connection between alcohol, appetite and weight is less apparent and a growing area of investigation.

Whole Grains
Whole grains receive much attention for their health benefits, but what exactly are whole grains, and why are they so nutritious?

Organic Foods
Organic foods are growing in popularity, but there is still confusion as to whether they are more nutritious and safer than conventional food.

Probiotics and Prebiotics
As the potential health benefits of probiotics and prebiotics have come to light in recent years, many people are interested in learning what they are, how they work and the strength of the science behind the claims.

Non-Caloric Sweeteners and Weight Management
Non-caloric sweeteners have been researched extensively and have been found to be safe to use. However, their use as a weight-loss tool is still unclear.

Introduction to the Glycemic Index
Making food choices based on Glycemic Index scores can help in the treatment of diabetes and high cholesterol levels.

Glycemic Index and Weight Loss
Experts disagree on the connection between a high or low GI diet and weight loss.

Macronutrient Recommendations
A diet that is balanced in its macronutrient distribution can help reduce the risk of disease and foster lasting weight loss.
