Grapefruits
The main characteristics of grapefruit
Grapefruit is one of the most particular citrus fruits. First of all, it is of considerable size; in fact, it can reach 2 kg in weight. Furthermore, it is among the rare instances where a naturally occurring hybrid transforms into a distinct species. In actuality, the grapefruit was once the offspring of the sour citrus and sweet orange—that is, the “original” citrus fruit along with the cedar. Grapefruit has maintained its unique identity and traits to this day. For instance, the citrus fruit has a lovely juice on the palate but is bitter. It is distinguished by a thick, non-spongy white section that lies between the peel and the pulp.
Nutritionally speaking, it takes the same route as other citrus fruits. It is naturally high in vitamin C, which supports healthy immune function. In terms of mineral salts, they are rich in phosphorus, calcium, iron, and potassium. Unlike many other citrus fruits, grapefruit is also regarded as a diuretic and an aid in digestion. It also aids in regulating blood sugar levels.
The different varieties of grapefruit
Grapefruit varieties are the result of crosses aimed at increasing the spectrum of tastes and colors. There are currently three macrovarieties available.
- Yellow (or white). It is the oldest variety, the “natural” one. Both the pulp and the peel are characterised by a very light shade, while the flavour is distinctly bitter.
- A fairly recent variety, it has bright pink skin and light pink pulp. While retaining bitter hints, it can be considered sweet.
- It is similar to pink but is characterised by a brighter colour, a sweeter flavour, and the presence of beta-carotene.
How to use this citrus fruit in cooking
Grapefruits are used similarly to other citrus fruits, with the exception of being eaten raw. Actually, it is typically too “intense” and bitter to be used as a “table fruit.” Either way, the juice can be used to create tasty smoothies, granitas, flavoured drinks, and alcoholic and non-alcoholic cocktails. It is often served with fruit juice.
More unusual uses for grapefruit include first courses, especially when served cold. If the aim is to create daring combinations and reproduce bittersweet-sour scents, grapefruit can help. Grapefruit can be used in cold pastas and rice salads (albeit in limited amounts). Below, you will find some recipes I selected that involve the use of grapefruit. There’s something for all tastes, including first courses!
Some delicious recipes
Grapefruit’s organoleptic and decorative qualities make it suitable for a wide variety of delectable and even savoury recipes. Here are the ones that struck me the most.
Puff pastry filled with cheese and citrus fruits. It is a very unique baked dessert, as the seasoning is halfway between sweet, savoury, acidic, and acrid. The grapefruit is cooked in small pieces (keeping the peel) together with the sugar until an irregular mixture is formed to be distributed on the pastry like a jam.
Glasswort, ginger, and grapefruit noodles. Here, the grapefruit serves as a condiment as well as a garnish. It is added raw, without any treatment other than dicing. It impacts the final result in terms of colour and taste.
Lettuce soup with prawns. In this recipe, the grapefruit acts as a garnish but still manages to influence the final result with its predominant flavour. It is used together with lime and orange to marinate the prawns.
Vegetables and citrus fruit mix. It is a very complex side dish that combines body, delicacy, and acrid hints. The vegetables are pan-fried, while the grapefruit and the rest of the citrus fruits are used raw.
Pot-cooked duck. This second course tastes fascinating, and it’s slightly acrid. A lot of citrus fruits, particularly grapefruit, are used in this recipe. Its peel is boiled with sugar and water and then served as a side dish to season the meat.
What are the benefits of grapefruit?
Some people believe grapefruit has medicinal qualities. It may seem excessive, but the benefits are truly numerous and very interesting. Let’s examine a few of them.
- It helps prevent cancer. The reference is above all to flavonoids and vitamin C, which have a good antioxidant function.
- Supports the immune system. By virtue of the presence of vitamin C, grapefruit has a positive impact on the body’s defenses. Other citrus fruit varieties likewise serve the same purpose.
- It is remineralizing. It contains many mineral salts, such as potassium and magnesium. By virtue of this, it helps maintain high energy levels and promotes the full recovery of strength.
- Lowers bad cholesterol. Certain scientific research shows a link between grapefruit and poor cholesterol. The effects are significant and occur in a relatively short time. An interesting detail when considering the consequences of high cholesterol (LDL cholesterol).
- Regulates mood. Although it falls short of chocolate’s potential, it improves mood nonetheless. It contains tryptophan, an amino acid that stimulates melatonin and serotonin synthesis. These two hormones promote the development of a relaxed mood and promote sleep.
Contraindications of grapefruit
As we have seen, grapefruit is good for your health; however, this only concerns balanced consumption, excluding medical contraindications. Certain individuals should drastically cut back on their grapefruit intake, such as those on medications meant to suppress the immune system or treat rheumatoid arthritis.
Negative interactions have also been reported with antiarrhythmics, with some clarithromycin-based antibiotics, with statins, and with some types of tranquilizers. The reason for this lies in the presence of furanocoumarins, substances that tend to “destroy” the active ingredients of drugs before they reach the blood.
But generally speaking, it’s advisable to steer clear of overindulgance. Grapefruit, if ingested beyond the recommended doses, can cause headaches, tiredness, and gastrointestinal disorders. In extreme cases and in predisposed individuals, it can overburden the liver and kidneys.
What about the allergic symptoms? Well, there is no real allergy to grapefruit, but rather an allergy to citrus fruits in general. The symptoms are the same as any type of allergy; therefore, they involve the body at a systemic, dermatological, and intestinal level. In this regard, you may experience itching, eczema, redness, swelling, nausea, and diarrhoea.

Cosa può fare per voi Nonnapaperina.it
Ho già introdotto il motivo per cui ho intrapreso il progetto di Nonnapaperina.it, ossia condivisione della mia esperienza e la possibilità, per tutti, di fruire di soluzioni a portata di mano per un’alimentazione a prova di intolleranze alimentari. Tanto vale, quindi, parlare un po’ del sito e dare qualche consiglio per “viverlo” al meglio. Ad esempio, per la vita di tutti i giorni, fate riferimento alla sezione “ricette per intolleranti”. Ne trovate a bizzeffe, tutte categorizzate per portata (primi, secondi etc.), momento della giornata (colazione, pranzo, cena), funzione (basi, impasti, creme, salse) e molto altro ancora. Non trascurate, però, anche la sezione sulle festività. Se il principio cardine del progetto è la condivisione, allora la palla passa presto a voi, quindi condividete liberamente le ricette con i vostri cari e con i vostri amici. E quale migliore occasione di una festività, sia essa il Natale, la Pasqua o la Festa della Mamma? Non di rado le ricette hanno un ché di artistico. I piatti porgono il fianco a un concetto “elevato” di cucina, che coinvolge non solo il senso del gusto, ma pone le basi per un'esperienza a tutto tondo. Il tutto a uso e consumo degli intolleranti alimentari, o degli amanti del buon cibo in generale. Il consiglio, comunque, è quello di spaziare. Il sito è basato sul principio dell’ipertesto, ossia ciascuna ricetta ne richiama altre, e molte altre ancora. Lasciatevi trasportare e vi sembrerà realmente di intraprendere un viaggio nella cucina anti-intolleranze alimentari, nella sua versione più “friendly” e divertente! Buona degustazione a tutti! Intolleranze alimentari e allergie si sconfiggono a tavola Quello delle intolleranze alimentari e delle allergie rischia di diventare un problema di ordine sociale se non viene gestito con attenzione. In primis per le dimensioni del fenomeno. Si stima, infatti, che circa il 10% della popolazione soffra di un qualche disturbo legato all’assorbimento di sostanze alimentari e, allo stesso tempo, in grado di generare sintomi più o meno importanti. Sul banco degli imputati vi sono l’intolleranza al lattosio e la celiachia, che sono le patologie in assoluto più diffuse, ma vanno prese in considerazione anche l’allergia e la sensibilità al nichel. Per inciso, la distinzione tra intolleranza e allergia è fondamentale ai fini medici. I sintomi sono infatti diversi per tipologia o per intensità (o per entrambi). A fare il bello è il cattivo tempo è in particolar modo l’allergia, che coinvolge il sistema immunitario e quindi determina una sintomatologia spesso e volentieri sistemica. Le intolleranze alimentari, invece, producono prevalentemente sintomi gastrointestinali. Discorso a parte per la celiachia, che tecnicamente non è un’allergia, ma coinvolge ugualmente il sistema immunitario. La distinzione tra intolleranza e allergia, tuttavia, assume una posizione di secondo piano per quanto concerne gli approcci terapici, o per meglio dire “di gestione”. Al netto di alcune eccezioni, che riguardano i casi di “scarsa tollerabilità”, intolleranze e allergie vanno trattate allo stesso modo, ovvero evitando le sostanze che creano i disturbi. Nella quasi totalità dei casi, infatti, non esiste una terapia risolutiva e quindi la guarigione è un'ipotesi da escludere. Ne è consapevole chi viene raggiunto da una diagnosi di intolleranza o allergia. L’impatto emotivo della diagnosi è molto forte proprio per l’impossibilità di raggiungere una guarigione completa. Sia chiaro, il disorientamento iniziale è fisiologico e giustificato. Tuttavia, deve essere destinato a durare poco, ovvero il tempo necessario a prendere atto della buona notizia riguardante intolleranti e allergici: convivere con questi disturbi si può! E’ possibile quindi convivere con i disturbi alimentari senza rinunciare ai propri piatti preferiti e senza dire addio al proprio stile alimentare.Non surrogati ma scelte alimentari consapevoli
Le intolleranze alimentari e le allergie si combattono non solo con le armi della medicina, ma anche attraverso un cambio di mentalità, che a sua volta coinvolge il modo di intendere la cucina. Il trucco è semplice, basta non guardare agli alimenti anallergici e anti-intolleranze come a dei surrogati degli “alimenti normali”. Gli alimenti per intolleranti sono infatti alimenti dotati di una propria specificità e in grado di offrire molto sul piano organolettico e visivo. Chi soffre di intolleranze alimentari e di allergia non dovrebbe replicare il consumo di latte, pane o altri alimenti, ma dovrebbe valorizzare gli alimenti a cui può attingere in tutta sicurezza. Adottare questo approccio significa innanzitutto svincolarsi dal ruolo del “malato”, focalizzandosi in realtà su altri alimenti. Ad aiutarci in questo senso c’è la natura con le sue molteplici varietà. Gli alimenti che fanno al caso del celiaco, o all’intollerante al lattosio, sono numerosi e spesso buoni e belli da vedere; inoltre sono molto versatili in quanto possono dare inizio a molte ricette davvero sfiziose. Non lo sono solo per chi soffre di queste patologie, ma anche per tutti gli altri. Le implicazioni dal punto di vista sociale sono evidenti. Col mio sito di cucina porto avanti esattamente questa filosofia. Non è solo uno spazio per conoscere ricette, ma anche un vero e proprio manifesto per chi vuole affrontare le intolleranze alimentari con armi meno tediose di quelle esclusivamente sanitarie. In quest’ottica la farina di riso non è un surrogato della farina tradizionale, ma un elemento a parte con cui realizzare ricette deliziose, che si abbinano con una grande varietà di ingredienti. E lo stesso, ovviamente, si può dire delle farine di amaranto, di fonio, di quinoa etc. Un discorso simile può essere fatto anche per l’intolleranza al lattosio. Al netto della possibilità di delattosare il latte, le varianti vegetali godono di una propria dignità gastronomica e porgono il fianco a un interessante approccio creativo in cucina. Tra l’altro, questo cambiamento forzato pone le condizioni per un viaggio attraverso le cucine alternative e gli alimenti più esotici. Ecco che si capovolge la prospettiva: intolleranze e allergia non sono solo una condizione gestibile, ma anche un’occasione di arricchimento.Intolleranze alimentari e socialità, un falso problema
Un altro dei motivi per cui la diagnosi di intolleranza o allergia fa molta paura, gettando nello sconforto chi ne soffre, riguarda le implicazioni per la vita sociale. Chi ha ricevuto una diagnosi da poco è convinto nella maggior parte dei casi che la sua patologia inciderà negativamente sulle occasioni di socialità, sia dal punto di vista psicologico - emotivo che dal punto di vista pratico. Il timore è quello di sentirsi diversi e in qualche modo lontani dai canoni della normalità, questo può portare a disagi anche tra parenti e amici. In realtà sono paure infondate. In primo luogo una condizione patologica non corrisponde a una condizione di “anormalità” (al netto dell’inconsistenza semantica del termine). Secondariamente basta un minimo di organizzazione e di consapevolezza per gestire anche le occasioni di socialità. Anzi, quando queste si svolgono fuori di casa, ossia nei locali adibiti alla ristorazione, la questione è addirittura più semplice. I gestori infatti sono nella maggior parte dei casi preparati ad accogliere clienti con intolleranze e allergie. In ogni caso basta informarsi prima e scegliere di conseguenza. Ma il problema non si pone nemmeno se si mangia a casa di altri, o se si invitano a casa propria delle persone. In primo luogo perché le diagnosi di questo tipo non fanno scalpore in quanto sono ormai molto diffuse. In secondo luogo perché i piatti per chi soffre di intolleranze alimentari sono in realtà buoni per tutti, anche per chi non soffre di alcun disturbo. Al netto di tutto ciò, se si pone attenzione al tema della contaminazione alimentare, cucinare per intolleranti alimentari (o per allergici) è più semplice di quanto si possa immaginare.Never self-diagnose!
There is a lot of talk about food intolerances and food allergies. The problem is that it is often talked about badly, the waters are muddied and ineffective advice is given.
For example, there is a common idea that intolerance and allergy are the same thing. It’s not like that. Of course, from time to time the symptoms overlap, and a substance can simultaneously cause intolerance and allergy, but these are two different disorders.
Intolerance is the negative reaction to taking a certain substance. Allergy, on the other hand, is the negative reaction to contact with a certain substance. This contact can be the result of actual intake, but it is not exclusive, i.e. it can also only occur at a skin level.
Intolerance rarely involves the immune system, while it more frequently involves the organs of the digestive system. In the vast majority of cases an individual is intolerant because his body does not contain the enzymes necessary for the metabolism of a substance. This is the case of the lactase enzyme for lactose intolerants. On the other hand, allergies always involvethe immune system. For often genetic reasons, the organism identifies an “enemy” in that specific substance, a foreign and dangerous body, and therefore reacts in a “disorderly” manner.
Differences are also noted regarding the incidence. The percentages change from population to population, given and considering the strong genetic component of these disorders. However, according to recent estimates, up to 4% of the population suffers from some form of food allergy. However, the percentages regarding food intolerances are even higher. There is also talk of 20-30%. The data is “dirtied” by the incidence of lactose intolerance, which is incredibly widespread. Allergies tend to begin in the first years of life, and in some cases disappear by adulthood. Intolerances, however, appear more frequently after adolescence.
Symptoms and triggers
The heterogeneity of symptoms that allergies and intolerances cause also derives from what has just been said. Allergy symptoms are often systemic and violent, and can include severe malaise, rush and respiratory problems. If the interaction with the substance occurs on the skin, eczema may be noted in the contact area. This is the case of nickel allergy. There is no shortage, especially when taken, of gastrointestinal problems, such as pain, cramps, diarrhea and nausea.
The symptoms of intolerances are more limited and are mainly gastrointestinal. This occurs – in most cases – because the body is unable to assimilate the substance, therefore it produces gas in an attempt to do so. This abnormal quantity of gas causes the symptoms we have just described. This is precisely the case with lactose intolerance, in fact lactose remains mostly intact, rather than breaking down into glucose and galactose, stimulating an accumulation of gas.
A difference between allergies and intolerances, which is often mistaken for a common point, is the class of substances that trigger one or the other. In the case of allergies, the offending substance is a food as a whole. In the case of intolerances, it is often a molecule, a sugar or a protein. The most common food allergies involve milk, millet, wheat, eggs and shellfish. The most common food intolerances, however, concern lactose, gluten and so on.
This has varied consequences on living standards. In essence, those with allergies are much more compromised. Having to avoid a substance is one thing, having to avoid a food is another matter entirely. Just to give an example, those who are lactose intolerant can still drink milk and consume dairy products, as long as they are lactose-free. Those who are allergic to milk do not have this option.
How to diagnose allergies and intolerances?
The diagnosis of food allergies is essentially clinical, therefore it is the result of the observation of visible and empirically measurable reactions. This has led to the belief that even a single individual can reach a diagnosis without the help of an expert.In reality, it is a huge mistake. Self-diagnosis is fallacious because to correctly identify the disease, a wealth of knowledge is needed which is useful for the interpretation of the phenomena. Furthermore, it is also dangerous as it risks triggering the symptoms of the disease.
It is true that the diagnosis passes through trials and errors, but these must follow one another from a risk reduction perspective typical of the medical profession. Therefore, yes to eliminating this or that element from the diet, to understand if it is precisely this that triggers the allergic symptoms. Yes also to adding further doses of the suspected allergen to check the body’s reaction, but according to very precise stages and indications, provided by the specialist. Intolerance is also diagnosed or more frequently “discovered” with the addition or subtraction of specific elements from the diet. However, the first aim is to exclude allergy, which is quite simple given the diversity of symptoms.
In some cases, some tests are available that guarantee a diagnosis. This is the case of the breath test for lactose intolerance. The patient is invited to consume milk, progressively. Subsequently, he blows into a machine that analyzes the composition of the air introduced. If there is an excessive quantity of carbon dioxide, then there is an intolerance, in fact the abundance of CO2 is caused precisely by poor digestion and malabsorption. If there is a suspected case of celiac disease, however, blood tests can be carried out to trace specific antibodies, as this pathology still “stimulates” the immune system.
