These recipes are easy to prepare, satisfying, and delicious. The recipes are a great way to add vegetables to your diet with lean protein. In one way, the pescatarian diet is more like a lifestyle. It is quite similar to the Mediterranean and the vegetarian diet, as all three dietary patterns focus on excluding red meat and poultry. However, they are different in many aspects. The next section highlights the similarities and differences between these diets. Keep reading.
Decoding Pescatarian, Mediterranean, & Vegetarian Diets
Pescatarian Vs. Mediterranean Diet
The Mediterranean diet is inspired by the traditional eating habits of people in countries bordering the Mediterranean Sea. It favors the usage of olive oil as the primary fat source, a high consumption of plant-based foods, moderate consumption of fish and poultry, and limited consumption of red meat.
The pescatarian diet shares many similarities with this diet, as both focus on fruits, vegetables, and whole grains. However, unlike the Mediterranean diet, the pescatarian diet food list does not include meat and poultry. Another key difference between both diets is the use of olive oil. While the Mediterranean diet emphasizes olive oil consumption, the oil is not a key component in the pescatarian diet.
However, like the pescatarian diet, the Mediterranean diet promotes heart health (9). Since both these diets are somewhat similar and emphasize the importance of plant-based foods, choose what works best for you. If you enjoy lean chicken and do not like fish and seafood, choose the Mediterranean diet or vice versa.
Whichever diet you choose, ensure it is balanced and meets your dietary requirements. You can follow the same rule while choosing between a vegetarian or a pescatarian diet, which we have compared in the following section.
Pescatarian Vs. Vegetarian Diet
The pescatarian diet has a lot in common with the vegetarian diet. Both include fruits, vegetables, nuts and seeds, whole grains, beans, and lentils, and stay away from meat. But there is a way in which the pescatarians part company from vegetarians – they eat fish and other seafood.
A plant-based diet involves a lower intake of saturated fats, which, in turn, may help lower LDL (bad) cholesterol and reduce the risk of heart disease. It also includes foods with high dietary fiber that may help lower the risk of gastrointestinal disorders (10). Since both vegetarian and pescatarian diets are plant-based, they offer similar benefits.
However, following only a plant-based vegan diet may lower the average plasma concentration of vitamin B12 (10). This is where adding fish to your diet may be beneficial. Studies state that including salmon fish protein supplements in your diet for eight weeks may help increase vitamin B12 levels (11).
Both vegetarian and pescatarian diets are healthy if you follow the basic principles of including whole, nutrient-dense foods instead of fried and processed foods. If you are ethically okay with eating fish, include it in your daily diet in moderation. If not, you may always choose plant-based protein sources like tofu or consult your doctor for supplement recommendations.
While the pescatarian diet has numerous health benefits and offers flexibility in meal planning and preparation, this one too, just like all other diets, has its own set of risks. Check them out in the next section.
Disadvantages Of A Pescatarian Diet
1. May Increase The Risk Of Mercury Poisoning
Fish and seafood carry a greater risk of mercury contamination. The symptoms of mercury poisoning are often mistaken for medical issues like gastritis and respiratory distress, leading to a wrong diagnosis. Excessive mercury exposure may have toxic effects on the body and may also damage the central nervous system and lead to coma and death (12),(13).
Since children and fetuses are highly susceptible to mercury toxicity, the FDA recommends that pregnant or breastfeeding women and children should avoid consuming high-mercury fish like king mackerel and tuna. They may eat freshwater fish like pike and bass in moderation (12).
2. May Not Be Ethically Sustainable
Pescatarianism is often considered more ethical compared to meat and poultry based diets. However, the issues regarding fish and seafood are quite different from meat. Aquatic and marine fishes are often harvested for food production and fish farming may not be an ethical practice. There are concerns regarding the deprivation of natural behavior, breeding, etc. On the other hand, wild fishing may lead to overfishing and pose a risk to the aquatic system (14).
Other than these concerns, the diet may be against people’s ethical beliefs as you are still eating animals (15). The only alternative to this is adding plant-based proteins like lentils, soy, tofu, and tempeh to your diet.
Furthermore, seafood, especially wild-caught varieties that are more nutritious, can be expensive, and so can fresh foods such as vegetables, fruits, and fish(15).
Always remember that it is important to consult with a healthcare professional or dietician before making significant changes to your diet. This will help you get the most out of your chosen diet while avoiding its disadvantages.
The pescatarian diet is perfect for you if you want to add more protein and healthy nutrients to your plant-based diet. While the diet allows you to consume a variety of fish and seafood, keep in mind that it is not an all-fish diet. In order to make it balanced, you may have 2 to 4 fish or seafood meals per week. The remainder of your meals should be plant-based. Also, avoid sweets and processed foods if you aim to lose or maintain weight on the pescatarian diet. In addition to this, follow healthy lifestyle practices like exercising regularly, drinking adequate water, and ensuring proper sleep.
