In addition to lead to obesity and harm the metabolism, the junk food biologically that prevents a person improve their diet. The brain is programed to prevent the excessive consumption of a single type of products in search of a balanced diet, but an unhealthy diet inhibits this natural mechanism.

A group of scientists from Australia carried out a study with two groups of rats. The first group was a diverse diet, while the second only ate biscuits, cakes and other products high in calories and fat. The rats were offered two types of water with two different flavors, each accompanied with a different sound.

Throughout the experiment – which lasted two weeks, the rats with healthy diet began to ignore the signs of the water if you have recently had already drunk the flavor that offered them. This is the normal behavior: eating or drinking more of the same would be excessive.

On the other hand, the group with the unhealthy ration not noticeable difference and drank the water every time he wanted possibility without differentiating the flavors, leading to excessive consumption.

What is amazing is that after you return to a healthy diet the second group of rats did not change their behavior, what would be a lasting nature of the food habits caused by junk food. The scientists believe that the outcome of the study deserves a detailed investigation and intended to repeat the experiment with a longer term.

Often when we talk about or hear the term “fat” automatically think of terms such as obesity, cholesterol, fat, poor health… however perhaps there are some things about fats that do not know and that you must take into account the time to follow a healthy diet, since not all fats are bad and, in addition, fats are absolutely necessary for our body.

Fats, along with the carbohydrates and proteins, they are the three basic nutrients that our body needs to stay alive and with energy. We cannot live apart from any of these three macronutrients, therefore you must know that the fat, in its fair measure, are very healthy.

In addition, as carbohydrates are not all equal (see our article about carbohydrates and glycemic index), fats are not all equal. You can distinguish up to three different types:

Saturated fats: These fats are “bad”, which you should avoid at all costs. Well, not how to avoid both, but if you moderate your intake. These fats usually come from foods of animal origin, such as meat, eggs or milk.

Unsaturated: These are the most healthy and help regulate our cholesterol level. Can be found in foods such as soy milk, vegetables, or fish, and is highly recommended prioritize the intake of these fats before that the saturated.

Polyunsaturated fats: These you should also try to avoid them as they are saturated.

Well, now that you know which types of fats are good, we are going to recommend a number of foods that contain unsaturated fats instead of saturated and that, therefore, you must prioritize these in your diet such as dried fruits, mainly walnuts and hazelnuts.

This also includes fish such as salmon or the blue fish. The salmon is a fish that, although it contains many fats, these are unsaturated, so they are healthy. The fat of the fish is, primarily, the well-known omega 3.

The soy milk, in addition to having all the benefits of milk and do not have lactose, has a significant amount of healthy fats.

Virgin olive oil: One of the sources of unsaturated fats that you must incorporate from already to your diet, as well as the food belonging to the Mediterranean diet.

Unsaturated fats have certain benefits to our body that will be key especially in more advanced ages, such as helping to regulate our cholesterol level, and other benefits that are important in all ages, as that helps to prevent obesity and improve our cardiovascular system, making us find more energetic and preventing diseases of the reason.

The sugars in the daily diet should not contribute more than 10-15% of the total calories ingested, however, its excess not only involve an increased risk to achieve a positive energy balance, but that the negative effects of eating sugar in excess go beyond the calories. Below we show you in that other aspects is detrimental consume sugar in excess.

Sugar can increase the risk of deficiencies in the B vitamins. The sugars and carbohydrates in general need of the B complex vitamins for your metabolism, therefore, consuming a lot of sugar will increase the demand for these micronutrients and if your intake is low, we have more risk of deficiency in the B vitamins such as B1, B2 and B5.

Increases the blood triglycerides: an excess of sugars in the diet combined with a great fat intake, you can promote the synthesis and accumulation of triglycerides in the body, therefore, to moderate the contribution of carbohydrates with the simple foods will help to prevent a hypertriglyceridemia that can translate into higher cardiovascular risk if it occurs.

Dental Caries: it is known that foods rich in sugars are the basic substrate of the cariogenic bacteria, therefore, an excessive consumption of substrate will increase the likelihood of having dental and oral diseases such as caries.

Increased risk of acne: people who are prone to acne should know that the great release of insulin which causes consume simple sugars in excess, it can mean a resurgence of acne, therefore, this is another of the negative effects of eating sugar in excess.

Of course, the negative effects of excessive consumption of sugar go beyond calories and this has been demonstrated recently. In addition, we cannot fail to say that the more calories without micronutrients that represents eating sugars in excess may mean obesity. That is to say, beyond the calories and the risk of being overweight, we should all take care of the consumption of sugar if you want to benefit the health with diet and not harm it with what we eat.

Usually associate the fats to a poor health or a type of nutrient harmful for our body, and is not as well. Fats along with carbohydrates are one of the main sources of energy in our body, which makes them essential in our diet, and we must consume moderately.

To begin we’ll start with the healthy fats. Are those that belong to the group of the unsaturated. Fats are in a pure state it is say, no other agency has transformed previously, which is why they are available to our body in order to be processed to your whim and exploited to the maximum. This type of fat found in plant foods such as olive oil or virgin olive oil on the fish at the in the form of omega 3. Regular consumption is essential for the proper functioning of our body.

A diet rich in this type of unsaturated fatty acids will help us to prevent diseases such as cardiovascular disease, because its depurative properties of the blood have the function to reduce the level of cholesterol and triglycerides in the blood, with what our blood pressure will be reduced, and with it the risk of stroke. In addition, they help to regulate our body disorders such as avoiding obesity…

On the other hand we have the saturated fats, which are also essential for the proper functioning of our body, but their consumption should be very limited. This type of fat found in meat, coconut and palm oil, widely used in the industrial bakery and industrially processed foods. A regular intake of this type of food will lead to increased cholesterol, reducing the body’s ability to subdue him, which leads to an increase in cardiovascular diseases as well as an imbalance in our body.

For all these reasons we must consume mainly unsaturated fats that we will provide the health and welfare necessary for our body, as well as the energy that we require for the proper functioning of the body. It is the processed foods that contain the artificial chemicals that can harm our body.
