Living a healthy lifestyle is really not that hard. The problem is trying to avoid all of the things that make life fun but are not exactly healthy for you. The key is to remember that moderation is your best friend; with it you can enjoy some of the bad stuff and still remain healthy, as long as the bad stuff is not too bad. The idea is to figure out where the line is and stay just inside it without crossing over too much, and to know where that line is well enough that you can enjoy yourself without worrying too much about the negative aspects. Finding that line can be pretty difficult, but it is there.
Even the best health scientists disagree about which foods are dangerous and which should be avoided; this is not that their advice should be disregarded as virtually worthless, but that it is important to listen to what they are saying. Consider the advice that processed meats cause cancer: While there is plenty of evidence that bacon and other meats cause cancer, there is also a school of thought that, in small amounts, they can actually be good for you. As such, it may not be such a bad thing to include some bacon in a healthy diet. Just look at all of the old men that live past 90 that swear fried foods were the key to their longevity: They may not have eaten fried foods with every meal or every day, but they were nonetheless part of the diet.
While there may be the inclination to ignore medical advice when it comes to food, especially when the advice seems to change every few years, pay special attention to what is actually being said. Few doctors have ever okayed a diet based on fried foods, but there have been concessions that some fried foods may not be all that bad for you. Combined with an otherwise healthy diet, a lot of exercise, and recreation geared towards relieving stress, a few fried foods every so actually contributes just enough bad cholesterol to the diet to make for a healthy person. Does this mean that you should eat a pound of bacon every day? No, but a few strips every so often will not kill you.
The key here is that moderation in all things, even moderation, is the key to a healthy lifestyle. You should be able to enjoy your health, and sometimes you need to be able to relax and enjoy a fun meal without guilt; if your diet does not allow you a few treats every so often then it may be time to take a serious look at the diet or find one that does allow you to enjoy yourself every so often.
