A healthy dietary lifestyle is known to provide an array of benefits, from increased energy to improved appearance. A nutrient-rich diet is likewise crucial in preventing and treating particular illnesses. Whether you are elderly, young, fit or battling illness, a healthy diet may help improve your current state of wellness and prevent a variety of illnesses from developing.
Colds and Flu
A diet low in nutrients provides little protection against viruses, such as the common cold and influenza, or the flu. According to the Linus Pauling Institute Micronutrient Research for Optimum Health, a diet rich in foods that contain phytochemicals (chemicals produced by plants) are associated with improved physical health. These foods, which include fruits, vegetables, legumes and whole grains, also offer an array of powerful antioxidants that help the body combat infection and disease. Conversely, excessive sugar or alcohol intake may impair the immune system's abilities.
To prevent or reduce symptoms of colds or the flu, consume a balanced, nutrient-rich diet that includes plenty of fruits, vegetables and whole grains. Vitamin C in particular may help prevent colds and flu, so be sure to regularly choose valuable sources such as oranges, grapefruit, citrus juices, tomatoes, spinach, strawberries and kiwi fruit.
Cardiovascular Disease
A diet poor in nutrients may heighten your risk for cardiovascular disease. According to the American Heart Association, a healthy diet is one of the most significant tools humans have to fight heart disease, a leading cause of death in America. Unhealthy foods, such as those containing saturated fats or trans fats, can cause plaque build up in arterial walls, potentially leading to heart attack or stroke. In addition, foods low in nutrients such as processed snack foods, white flour-based products and most sweets are associated with overeating and weight gain, all of which raise people's risk for cardiovascular disease.
To prevent or help treat cardiovascular conditions, eat a nutrient-rich diet that includes healthy foods such as fruits, vegetables, legumes and whole grains. Incorporate modest amounts of healthy fats such as olive oil, fatty fish, nuts or seeds into your diet regularly and limit intake of foods containing unhealthy fats, such as red meat, dark-meat poultry, butter, whole milk and deep-fried foods.
Metabolic Syndrome
Metabolic syndrome refers to a combination of weight and diet-related conditions such as increased blood pressure, elevated insulin levels, excess body fat around the waist and/or unhealthy cholesterol levels. The disorder raises a person's risk for diabetes, heart attack and stroke significantly. According to the University of Chicago Medical Center, sedentary lifestyle, a high body mass index (BMI) and a high fat diet are common risk factors associated with metabolic syndrome. Though research is still being conducted to determine the specific cause of the disorder, it does appear to strongly correlate to America's rise in obesity.
To prevent or help treat metabolic syndrome a nutrient-rich diet, coupled with regular, physical activity and maintaining healthy body weight is encouraged. Begin by increasing nutritious foods, such as fruits and vegetables, in your diet and work to limit or reduce intake of high-fat foods, sugary sweets and processed foods, such as white bread, pastries, chips and pretzels. For best results, seek guidance and supervision from a qualified medical or dietary professional.
