Misconceptions about food have been around for centuries. For instance, it was once believed that the tomato was poisonous. We now know that the tomato contains many nutrients beneficial to health. What’s more, can you imagine pasta without marinara? Presently, some common myths include that a multivitamin is a healthy substitute for fruits and vegetables, that combining certain foods can boost your metabolism, and eggs raise your cholesterol. While some of these claims sound true enough, they rarely have any basis in fact. Separating truth from fiction can often be a challenge, and determining the best strategies for eating smart is no exception. The following may help to dispel some of these myths.
Myth: Multivitamins are a substitute for the recommended five servings of fruits and vegetables. A pill can not take the place of food. Fruits and vegetables provide much more than just vitamins and minerals. They’re packed with phytochemicals (plant-based compounds that may help prevent chronic disease), and fiber which is good for the heart and keeps cravings at bay.
Myth: Combining certain foods in the same meal may boost metabolism and weight loss. The idea is to eat protein and starch containing foods separately so digestive enzymes work more efficiently to boost metabolism and enhance nutrient absorption. However, no combination of foods will speed up metabolism or burn fat and calories. The body is designed to digest all types of foods, no matter when or how they are eaten. Healthy eating habits and regular exercise is the best combination for weight loss.
Myth: Eggs raise your cholesterol. Eggs have been getting a bad rap for years because they are high in cholesterol. However, if your cholesterol levels are normal, you can safely eat up to three or four eggs a week as recommended by the American Heart Association. In fact, it is saturated fat that has been shown to raise cholesterol levels and the risk for heart disease and stroke rather than cholesterol itself.
Myth: Beef is bad for you. While some cuts are high in saturated fat, two servings of lean beef a week can actually be beneficial. Beef contains a highly absorbable form of iron needed for the production of red blood cells. Lean cuts, like those from the loin or round provide as few as four grams of fat in a three-ounce serving.
Myth: Fresh fruits and vegetables are healthier than canned or frozen. Actually, canned or frozen fruits and vegetables may have as much nutritional value as fresh, and some may have more. Canned and frozen produce is picked fully ripe and processed almost immediately, thus helping to preserve the nutrients. Remember though that canned vegetables are higher in sodium and fruits packed in syrup often have more calories than fresh.
Myth: Carbohydrates make you fat. The truth is eating extra calories causes weight gain, whether from carbohydrate, protein, or fat. Carbohydrate is the body’s fuel of choice; omitting them from the diet may increase your risk of kidney problems, osteoporosis, and fatigue. The recommendation is that at least 50 percent of your daily calories should come from complex carbohydrates such as whole grains, rice, pasta, and legumes.
Myth: You can eat more low-fat and fat-free foods without gaining weight. Calorie for calorie there is not much difference in low-fat and full fat foods. Food manufacturers often replace the fat in these products with high-calorie fruit purees, sugar, and salt to make up for the missing flavor. It is wise to read the labels and keep counting calories.
