I NEED HELP PLEASEEEE!!!

New guidelines were recently published by the U.S. Department of Agriculture (USDA) to improve the way people eat. Recommendations include lowering salt intake, eating less sugar and saturated fats, and eating more fruits and vegetables. These guides have come out every 5 years, but though they are developed by reputable scientists, the public virtually ignores them. Countless studies have linked overeating and sedentary lives with multiple diseases and increased medical costs. Even with high-profile figures like Michelle Obama leading the fight for healthier lifestyles, the old habits die hard.
The need to shift to healthier eating is more urgent now than ever. Weight problems are epidemics in the United States, as is the equally pressing problem of undernourishment. For example, people today eat far too much salt. This salt addiction has been proven to increase the risk for heart disease and stroke, as well as other costly and life-threatening illnesses. The new guidelines give specific recommendations regarding how much daily salt is healthy. However, it's doubtful whether Americans will heed the advice. They'd rather watch cable TV and eat French fries than make changes that would likely prolong their lives.
Thankfully, the USDA has become proactive in changing the way we Americans eat. Most people are familiar with the famous food pyramid the agency developed years ago, showing the food groups and servings of each group. However, the agency's guidelines go far beyond the colorful posters hanging in schools across the nation. School meal programs are impacted by the document, as are decisions about the labeling of foods and how foods are marketed to young people. In particular, by using the guidelines to target school breakfast and lunch programs, the USDA hopes to make healthy foods an easy alternative for kids. Clearly, adults cannot be counted on to make healthy eating a priority. With the USDA's help, school kids will get started early on a lifetime of good diet habits.
