Types of Diets: Are all of them healthy?

Types of Diets: Are all of them healthy?

One of the most determining factors when it comes to knowing someone is the diet they follow, because many characteristics and unique aspects of their personality are related to this factor

This is why it is so important to know the types of diets that exist so that we can choose the one that better suits our lifestyle. Each one of them is based on theories that seek to prove their efficacy and importance to achieve an optimal state of health.

Some of the most popular ones are:

Omnivorous Diet

It is considered one of the oldest ones and it is the most common diet among human beings, which makes it the most popular. It is a diet that involves eating food that comes from all kinds of animals and plants.

The Omnivorous Diet follows the famous food pyramid by eating products from all the segments of this pyramid.

It provides a wide variety of components that are necessary for the proper functioning of the body

An omnivore meal

Despite being considered the primary diet of human beings, many studies in this field and in the effects that certain foods have on the organism have created a basis for the growth and development of other diets that limit certain components that are common in an Omnivorous Diet.

This is the reason why vegan and vegetarian diets have experienced such success recently.

Ketogenic Diet

This is a diet that focuses on a high consumption of fat but low in carbohydrates. It mainly seeks to force the body to burn as much fat as possible, so it tends to be chosen for weight loss processes.

The main feature of a Ketogenic Diet is that it reduces the consumption of carbohydrates, without paying attention to the requirements. With this, the liver will transform fat into fatty acids and ketone bodies or ketones due to the reduced supply of carbohydrates.

Ketones are in charge of replacing glucose to serve as a source of energy for the brain

Avocado cut in a half

The human body enters a state of ketosis when there are high levels of ketone bodies. Some studies have proven that it even helps to reduce the frequency of epileptic attacks, which is why it is advised to control this disorder in children, although not everybody agrees

Foods advised for ketosis

Some of the foods advised for a Ketogenic Diet are: fish, seafood and meat, eggs, vegetables that grow on the surface of the earth, cheese and natural fats such as olive oil, nuts, avocado…

Meanwhile, we should avoid other products like pasta, rice, sweets, potatoes, many fruits and bread.

The concerns with the Ketogenic Diet are mainly due to a vitamin B1 deficiency, an increase in cholesterol, the onset of kidney stones and cardiovascular problems

Paleo Diet

This system is mainly based on the products that were consumed during Prehistory by human beings, which means that they consume supplies that could only be found during the Palaeolithic period.

This type of diet tries to distance itself from modern diets and their refined and processed products, which are responsible for the onset of diseases like Parkinson, coronary heart disease and even mental health problems.

Main benefits of the Paleo Diet

  • Weight loss or keeping a healthy organism by avoiding processed foods, which also help us to control the appetite. Moreover, it also contributes to preventing cardiovascular diseases by reducing the triglycerides and increasing our tolerance to glucose.
  • Reducing the chances of suffering diseases such as obesity, degenerative disease, cancer and even diabetes.

Paleo thumbs up or thumbs down

In order to follow the Paleo Diet, we suggest eating: fruits and vegetables, seafood and lean meat, nuts and seeds, healthy fats…

We should avoid mainly processed foods, dairy products, grains, alcohol, sugars and legumes. In this sense, it is similar to the ketogenic diet.

Vegetarian Diet

The Vegetarian Diet is historically the second oldest type of diet that exists. It can be chronologically located in the first civilizations from the India and Greece (5th and 6th century BC). The principles of this diet have been associated with philosophical and spiritual purposes, like Pacifism and faith.

Currently, the Vegetarian Diet is related to respecting nature and animals

What does a vegetarian person eat?

A vegetarian diet is based on plants and their fruits. It avoids animal proteins like meat and fish. Even though there are some exceptions like honey, milk and eggs.

The benefits of a Vegetarian Diet for the body are mainly due to the low consumption of saturated fats and cholesterol.

A vegetarian meal

Moreover, it is quite useful when it comes to preventing disorders related to colon and prostate cancer as well as obesity and diabetes thanks to the importance of fiber within this diet

When dealing with a Vegetarian Diet, the doctors are mainly focused on controlling the consumption of micronutrients like minerals, vitamins and fiber, since it has to be done consciously.

The same happens with the omega-3 fatty acids

If we follow a vegetarian or vegan diet but we do not do it properly, we could suffer serious consequences. Some of the main problems that we can find are… keep reading

Vegan Diet

A Vegan Diet goes beyond a change in the foods we eat, it is considered a lifestyle that deeply rejects all type of animal exploitation. This is why it avoids the consumption of any product that has been obtained from animals or their suffering.

So, apart from food, veganism is also aware of the cosmetics, textile and even plastic industries

Go Vegan

Once we understand this concept, we will understand why someone who follows a Vegan Diet does not consume any food or product from animals

This involves not consuming eggs, meat, fish, milk and honey, among others

Nutritional Deficiencies

Due to the requirements of our body and the increasing popularity of this movement, there are products that have been designed to supplement and meet the possible deficiencies that this type of diet can entail.

So nowadays, we can use products like soy or almond milk instead of cow or sheep milk, sesame or sunflower cheese instead of conventional cheese, and even substitutes for eggs like tofu.

Although let’s not forget that an animal protein is not the same as a vegetable protein

The risks or problems that someone who follows a Vegan Diet can suffer sometimes occur due to a lack of information, which is why it is always advisable to consult a professional that will guide you through any type of diet.

The dangers lie mainly in a lack of vitamin B12, omega-3 fatty acids and proteins, which can cause problems in the red cells and the absorption of iron, among others
