When we consider food-type protein sources, we notice those of creatures beginning: meat, fish, eggs, milk, and subsidiaries. In any case, a whole class of protein sources from plant food varieties adds to a decent eating regimen, which is likewise vital in the Mediterranean. Proteins are fundamental as far as we’re concerned, particularly for the fundamental amino acids they contain: they are called that because our body can’t blend them freely.

Animal And Vegetable Proteins
Proteins are particles shaped by a chain of rings called “amino acids,” each with an alternate capability. Proteins are recognized by the amount and nature of these “rings” of which they are made, i.e., by joining 20 unique amino acids in both creature and vegetable food sources. Nine of these amino acids are designated “fundamental “since we should essentially accept them with the eating routine, while the rest are characterized as “unnecessary,” i.e., those that our body can deliver autonomously.
Difference Between Animal And Vegetable Proteins
Are plant or animal proteins better? Using adjectives such as “best” to distinguish proteins is improper.
The Science of Nutrition divides them into three categories :
- Proteins of high biological value;
- Proteins of medium biological value;
- Proteins of low biological value.
What Is Meant By The Biological Value Of Proteins?
The Study of Nourishment portrays protein quality with a boundary (or file) that assesses the amount, quality, and corresponding proportion of the fundamental amino acids that the protein contains and their natural job. Given the healthful significance of proteins and the trouble of assessing their organic worth, it ought to be stressed that researchers are as yet taken part in their assessment, both for those contained in food varieties and enhancements. It is, hence, a region in constant refreshing. To work on a mind-boggling matter, for example, protein assessment, it very well may be, for the most part, expressed that:
- Proteins of animal origin (eggs, milk, and derivatives, meat in general, fish, etc.) are of high biological value;
- Legume and soy proteins have a medium biological value but are more similar to that animal proteins ;
- Vegetable proteins (derived from cereals and starchy foods) are of low biological value, as they do not contain essential amino acids and are present in small quantities.
It should also be said that we intake amino acids similar to meat by eating cereals and legumes ( single dishes ), such as pasta and beans or rice and peas.

Essential Amino Acids
There are nine essential amino acids for human nutrition:
Among these, stretched chain amino acids should be recognized for their significant capabilities: leucine, isoleucine, and valine, which assist with fixing muscle filaments harmed by muscle use, as well as make energy promptly accessible because they don’t go through the liver. Moreover, they help to balance weariness and the creation of lactic corrosives: for this large number of capabilities, they are significant for the people who play sports. Fundamental amino acids are additionally somewhat tracked down in plant food varieties however are chiefly present in:
- Eggs (in the albumen);
- Meat, poultry, fish;
- Milk and Yogurt;
- Fresh or aged cheeses such as Grana Padano DOP.
This cheddar is a concentrate of milk supplements; it contains 33% of high natural worth proteins, including nine fundamental amino acids (3 of which are fanned); besides, it is the cheddar most extravagant in calcium on an equivalent weight premise among those generally ordinarily polished off, it gives cell reinforcements like zinc, selenium, and vitamin A, as well similar to a magnificent wellspring of vitamin B12. Grana Padano DOP doesn’t contain lactose or gluten; it has less fat than entire milk, with which it is made because it is somewhat skimmed during handling. The fats of Grana Padano DOP are around 29%, of which 32% are unsaturated.
Where Are Plant Proteins Found?
In a balanced diet, proteins are not considered only for their biological value but also for the amount consumed.
Adults should take 0.8-1 g of protein per kilo daily; if they are sporty, 1.3-2 g depending on the type of physical activity.
Among the foods richest in vegetable proteins are legumes :
- Fava beans
- Grass peas
Legumes have the advantage of being relatively low in calories, offering an interesting content of complex carbohydrates and fibers, and promoting satiety, allowing for better control of hunger.
- Soy, in particular, contains over 30% protein and can be consumed in various ways, from a drink to tofu, from flour to tempeh. There are also numerous soy-based products on the market, and it is a vegetable protein source also widely used by the food industry, especially as an emulsifier.
- Vegetable proteins are also contained in small quantities in oilseeds such as peanuts, which are legumes and have precious fatty acids, in dried fruit such as walnuts and almonds, in wheat used to make pasta, baked goods, sweets, bread, etc. ( gluten is a vegetable protein).
Five Tips For Consuming Legumes
For legumes, the average portion is: 50-70 gr for dry ones;150-180 gr for fresh, frozen, or canned water.
- In preparations with cereals, such as pasta and beans or rice and peas, etc., use a quantity of legumes proportionate to the cereals.
- It is advisable to use only extra virgin olive oil . and iodized salt to season legumes. Remember that legumes in preserved/brine water are already salty and that you shouldn’t exceed 5 grams of salt daily, including that present in the preparations.
- To limit the discomfort of swelling induced by eating legumes, remember not to exaggerate with the above quantities and prefer peeled legumes because eating legumes with their peel favors intestinal fermentation.
- Grandma’s old vegetable mill is also useful for preparing tasty legume soups, allowing you to separate the pulp from the peel. The soups can be seasoned with grated Grana Padano DOP instead of salt.
- Instead, be careful when using blenders or food processors: by blending legumes, including their peel, air will also be incorporated, and you risk having the opposite effect, i.e., even more, fermentation and digestive difficulties.
How To Cover Protein Needs Without Eating Meat
The main advice for those who want to adopt a meat-free diet (also excluding fish, shellfish, etc.) is to include foods such as:
- Eggs, milk, and derivatives
Not only to be sure of taking the right amount of high biological value proteins but to avoid the risk of a deficiency of precious micronutrients, first and foremost, vitamin B12. When legumes are taken, combining them with cereals (preferably wholemeal) is advisable to guarantee the balance of amino acids.

Benefits Of Plant Foods On The Cardiovascular System
The correct intake of plant foods is essential to protect our cardiovascular system because while we eat foods such as legumes, we also introduce “good” fats, i.e., monounsaturated, just as when we eat fish, we introduce proteins of high biological value, but also omega-three polyunsaturated fats. If, on the other hand, we eat red meat, for example, we introduce about 5% fat, of which a third is saturated, the ones called “bad.”
However, there are also two-thirds of “good” fats in meat. Saturated fats are associated with a higher cardiovascular risk. In contrast, monounsaturated fats (such as those in olive oil) and polyunsaturated fats in fish – but also in nuts and seeds such as flax seeds – are associated with a lower cardiovascular risk.
A balanced diet includes portions and frequencies of vegetable and animal foods for the balance between proteins and fats and the contribution of minerals, vitamins, and fibers.
Regarding proteins and fats, it is necessary to respect a varied and balanced diet, where the proteins are mostly vegetable and in the minority animal, while the fats are mostly vegetable.
It’s about following a complex, balanced diet because choosing a portion of food based on nutrient intake is difficult while shopping. For this reason, it is advisable to consult a nutritionist who can prescribe the right diet for everyone. However, educational programs offer a balanced diet, indicating the amount of food and the frequency of consumption, having correctly calculated the nutrient content.

To better protect the cardiovascular and digestive systems, the fibers contained in vegetables are very important, recommended daily at main meals, and of course, fruit: 3 fruits a day, equal to about 450 g of fresh fruit.
