What foods to avoid

First of all, most people have the misconception that eating healthy means that you need to cut out a lot of the foods that you eat now, but that is not the case. The key to having a healthy diet is moderation. You need a balance of all the types of macronutrients and micronutrients to be healthy. Also, simply cutting certain foods out of a diet makes it difficult for you to adjust. Instead, try to limit the amount of the food that you eat; perhaps have smaller portions.

Here are some specific foods that you should try to avoid. You should try to avoid fruit juices because they can contain up to 10 teaspoons of sugar per cup. Processed foods should also be eliminated because they are made with white flour and white sugar, which can cause your blood sugar to go up and down leaving you tired and sapped of energy. Also, canned fruit is often in sugary syrup, and dried fruit can be high in calories. Avoid fried vegetables and those with dressings or sauces as well, as these have unhealthy fat. Finally, it is very important that you limit your amounts of fast food and snacks because they can be loaded with tons of salt, which isn't good for you.
The fats that you should try to avoid are saturated fats and trans fats. Saturated fats can be found in animal sources such as red meat, dairy, and eggs. If you eat a lot of saturated fats, you can increase the cholesterol (LDL)in your blood, which is not good. If your levels of cholesterol are too high, you are at risk of things such as heart attacks, strokes, and narrowed arteries (atherosclerosis). Trans fats are used to extend the shelf life of processed foods, so usually they can be found in foods such as cookies, fries, cakes and donuts. Also, if any food contains "hydrogenate oil" or "partially hydrogenated oil" it likely contains trans fat. These trans fats also raise your cholesterol (LDL) level in your blood. Which could lead to other serious consequences, such as clogging your arteries, which can lead to strokes and heart attacks.

Eating too much sugar could be detrimental to your health, especially if your blood glucose level rises to high. If you have too much sugar, it can cause energy ups and downs and add to health problems such as arthritis, diabetes, osteoporosis, headaches, and depression. You shouldn't ban sugar from your diet, but it's just important to make sure that you have it in moderation.

The recommended amount of sodium is about 2,300 mg per day, the equivalent to one teaspoon of salt. This is most likely a lot less than how much you intake. If the kidneys cannot control the amount of sodium that you are eating, then there are many consequences. For example, high blood pressure, heart failure, kidney problems and kidney stones, stroke, gastric cancer, oedema, left ventricular hypertrophy, and osteoporosis. So it is best to limit fast foods and sodium rich snacks such as potato chips and pretzels.

As you can see, there are an abundance of foods that you should try to avoid. An over intake of these things could cause serious problems, so the best thing that you can do for you body is to maintain a healthy limit to those kinds of foods. That way, you will have this in moderation, which is not a bad thing.
