Pescatarian Diet Definition and Benefits

What is Pescatarian Diet? – Overview

The Pescatarian Diet is an alternative to a vegetarian diet that allows you to consume seafood.

If you like both a vegetarian diet and seafood, then the Pescatarian Diet might be an ideal choice for you.

In this post, we will clarify the Pescatarian diet, discuss its health benefits, and provide examples of how to follow this diet regularly.

This vegetarian diet includes fish and other seafood, such as shrimp, mussels, salmon, crabs, and lobster, in addition to plant-based meals.

The term “pesce” is derived from the Latin word “piscis,” which means “fish.” As a result, a Pescatarian diet contains both vegetarian and seafood meals.

It also shares many similarities with the Mediterranean diet such as prioritizing fruits and vegetables, whole grains, nuts, seeds, and fish as important nutritional categories.

Except for fish, all animals are forbidden on a pescatarian diet. This diet excludes all meat (such as red meat and chicken) or any animal parts.

It is considered an extension of a vegetarian diet, but thanks to the inclusion of seafood, adequate daily protein requirements may be easier to maintain.

Benefits of Pescatarian Diet. What is Pescatarian Diet Good For?

Maintaining a pescatarian meal plan is a highly healthy way of eating, and pescatarians are generally interested in the food they consume. The following are some of the health advantages of a pescatarian diet:

1. Increased levels of omega-3 fatty acids

Omega 3 Acids

Pescatarian Diet – Omega 3 Acids

When fish replaces meat as your major source of protein, you will naturally consume more omega-3 fatty acids.

Fatty fish are high in omega-3 fatty acids, which are polyunsaturated fats that have powerful anti-inflammatory action and aid in the prevention and treatment of many disease processes, including liver disease and metabolic disorders, as well as supporting heart function.

2. Avoiding Meat

Pescatarian Diet Definition – Avoiding Meat

Though a pescatarian diet is often well-balanced, it does not exclude meat as a source of protein.

Avoiding red meat and pork is very good for your health since it reduces saturated fat, which is highly dangerous and unhealthy and leads to insulin resistance and high cholesterol while raising your risk of cardiovascular disease.

On the other hand, only animal-based protein sources supply the proper ratios of essential amino acids, which are required for synthesizing muscle tissue, neurotransmitters, hormones, and enzymes and are, therefore, necessary for human health.

You may achieve a balanced amount of essential amino acids by eating a predominantly vegan diet with only periodic servings of fish.

3. Weight Loss

Weight reduction can be achieved by eating a predominantly vegetarian diet rich in vegetables and supplemented with healthy portions of fish.

Fruits and vegetables are low in calories and high in anti-inflammatory compounds, which can help you maintain a healthy weight and protect your heart.

As a result, sticking to a well-planned pescatarian diet increases your chances of losing weight.

Whitefish, such as cod and haddock, for example, are low in calories while yet offering a high protein content. 100g of cod, for example, provides 20g of protein for just 82kcals.

4. Diabetes and inflammation

What is Pescatarian Diet – Anti Inflammatory

Type 2 diabetes, high blood pressure, and obesity can all be reduced by following a plant-based diet.

Furthermore, anti-inflammatory and antioxidant compounds such as flavonoids are abundant in plant-based diets. Flavonoids are anti-inflammatory and anti-diabetic.

Potential Risks of the Pescatarian Diet

1. Vitamin B12 deficiency

People who eat meat are the only ones that receive enough vitamin B12 from their diet.

Supplementation is typically required for vegans and Pescatarians to maintain appropriate vitamin B12 levels.

Vitamin B12 is essential for neurological, mood control, and red blood cell formation.

2. Mercury content in seafood

Mercury poisoning can occur if a person consumes too much fish, although the risk is considered minimal.

Because not all fish have the same amount of mercury, it’s important to be aware of what you’re eating to limit your mercury exposure.

What Can You Eat on A Pescatarian Diet?

When beginning a new diet, be assured that you are obtaining all the required nutrients.

A Pescatarian diet often consists of various vegetables, fruits, legumes, potatoes, grains, pasta, beans, pulses, nuts, and any fish or shellfish.

Pescatarians eat dairy and eggs, such as cheese, yogurt, and milk, but they do not eat meat. In addition to any fish such as salmon, tuna, prawns, and lobster, you may consume foods produced from plants, dairy, and eggs.

Other foods that Pescatarians can consume include:

  • Canned sardines, salmon and tuna
  • Fruits
  • Grains and Seeds
  • Legumes
  • Shellfish
  • Seeds, such as flaxseeds and hemp seeds.

Here is what to eat on a typical day as Pescatarians:

A. Breakfast:
Breakfast consists of a large dish of oats (Tamryn’s preference) and a cup of bulletproof coffee.

B. Lunch:
A usual lunch consists of a good proportion of greens, beans, a bowl of salad with sweet potato, and healthy fats (like avocado)

C. Dinner:
Because this is the last meal of the day, keep it light, such as a fast vegetable stir fry with some fish.
