A High-Fat Diet Increases Risk of Breast Cancer

 

Women who eat diets high in fat and saturated fat increase their risk of developing breast cancer, according to a study published by the National Cancer Institute. Researchers looked at breast cancer subtypes defined by estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 receptor (HER2) using data collected from the European Prospective Investigation into Cancer and Nutrition-Oxford (EPIC) study. Diet records from 337,327 women over a period of 11.5 years were analyzed for fat content. The women who consumed the most fat had a 20 percent increased risk for ER-positive and PR-positive breast cancer subtypes, and women consuming the most saturated fat faced a 28 percent increased risk for the same breast cancer subtypes, compared with those who consumed the least. Risk of developing HER2-negative breast cancer was 20 percent higher among women consuming the most saturated fat.

Jaz ostajam pri svojem mnenju, da razne ketonske diete (=razmeroma visok vnos maščob) ne morejo biti zdrave na dolgi rok.

(razen tega, da gre za dieto, kar je tako ali tako zgrešen pojem, ker kaj pa ko enkrat gredo kilogrami, pa je treba vzdrževat težo?)

Kolikor sem pregledala jedilnike, večina tudi vsebuje visok delež živalskih beljakovin in maščob, za katere pa tudi znanost ve, da niso najboljše.

Je to replika meni? Ker se strinjava glede tega. Drugace bi pa opozorila na angleski izraz 'diet' - oni ga namrec uporabljajo kot dieto IN prehranjevanje nasploh (npr. 'healthy diet' - zdrava prehrana).

Ne direktno tebi, pač pa moj komentar na raziskavo To pa vem ja, da se tadva pojma meša. Ketonsko sem omenila kot primer.

Aja, sem razumela kot da navkjlub raziskavi ostajas pri svojem mnenju, pa mi je bilo cudno, ker se mnenji ne razlikujeta ravno hudo ; )  Nevermind me : D

Comparison of Nutritional Quality of the Vegan, Vegetarian, Semi-Vegetarian, Pesco-Vegetarian and Omnivorous Diet

Abstract: The number of studies comparing nutritional quality of restrictive diets is limited. Data on vegan subjects are especially lacking. It was the aim of the present study to compare the quality and the contributing components of vegan, vegetarian, semi-vegetarian, pesco-vegetarian and omnivorous diets. Dietary intake was estimated using a cross-sectional online survey with a 52-items food frequency questionnaire (FFQ). Healthy Eating Index 2010 (HEI-2010) and the Mediterranean Diet Score (MDS) were calculated as indicators for diet quality. After analysis of the diet questionnaire and the FFQ, 1475 participants were classified as vegans (n = 104), vegetarians (n = 573), semi-vegetarians (n = 498), pesco-vegetarians (n = 145), and omnivores (n = 155). The most restricted diet,i.e., the vegan diet, had the lowest total energy intake, better fat intake profile, lowest protein and highest dietary fiber intake in contrast to the omnivorous diet. Calcium intake was lowest for the vegans and below national dietary recommendations. The vegan diet received the highest index values and the omnivorous the lowest for HEI-2010 and MDS. Typical aspects of a vegan diet (high fruit and vegetable intake, low sodium intake, and low intake of saturated fat) contributed substantially to the total score, independent of the indexing system used. The score for the more prudent diets (vegetarians, semi-vegetarians and pesco-vegetarians) differed as a function of the used indexing system but they were mostly better in terms of nutrient quality than the omnivores.

Keywords: vegan; vegetarian; omnivore; diet quality; dietary pattern analysis

 

 

 

Conclusions

In conclusion, results concerning body weight, nutritional intake, nutritional quality and quantity

are in line with the literature on restricted and prudent diets versus unrestricted omnivorous diets.

The use of indexing systems, estimating the overall diet quality based on different aspects of healthful

dietary models (be it the US Dietary Guidelines for Americans or the compliance to the Mediterranean

Diet) indicated consistently the vegan diet as the most healthy one. The impossibility to score for

(a) specific component(s) for the restricted diets was compensated by the higher scores on most of the

other components. Adaptation with specific components (e.g., soy drinks instead of milk; inclusion of

other polyunsaturated fat sources instead of fish) may increase the relation with different types of

healthful diets, and this especially for the MDS system.

 

Nevertheless, the used indices may be useful as a screening method allowing the judgment of

specific diets.

Postala bom zeliščarka! Kupila sem si sveža zelišča - bolj malo sicer za začetek: baziliko, curry , rumeni origano in rožmarin. Zdaj pa so mi kar

malo prelepa, da bi jih uporabljala, haha.

Koliko joda naj bi vsebovala himalajska sol? Odrasla oseba naj bi na dan vnesla 150 mikrogramov joda.

Glede na spodnjo tabelo sploh ni tako enostavno doseči te številke (brez iodirane soli), še posebej, če se ne jé rib.

 

[Anouk]

V tem primeru je verjetno priporocljivo uzivanje morskih alg (tudi npr. v praskasti obliki - pred casom sta bili chlorella in spirulina precej popularni).

 

Drugace ima pa prehansko dopolnilo Veg1 od Vegan Society notri tudi 150 mikrogramov joda:

Jaz že dva tedna jem kelp (najprej sem ga v prahu, a mi je bil nagnusen, zdaj imam tablete). Počutje se mi je izjemno izboljšalo!! Metabolizem se mi je pospešil, lasje so mi nehali izpadati v tako velikem številu, manj sem utrujena, ne zebe me toliko, koža je manj suha, ta mesec sem imela menstruacijo spet 5 dni (namesto 8-10) in nisem imela migrene (kot ponavadi kakšen teden pred menstruacijo). 

 

Mislim, da sem imela že rahel hipotirodizem... 

 

Sicer pa tudi jaz že več let uporabljam izključno himalajsko sol, a mi je bilo očitno premalo... 

Imam pa te tablete, ki vsebujejo več joda, kot je trenutni RDA (za katerega sem brala, da je postavljen na tako nizko mejo, da še ravno preprečuje nastanek golšavosti, za kaj več pa ne zaleže). Pojem kar celo, čeprav na naši strani piše, da bi se naj vzela le polovička. 

[Matilda]

 

Jaz sem pravzaprav hotela s svojim postom napeljati na to, da je himalajska sol namesto navadne morske z jodom larifari, ampak

nisem našla podatka o tem, koliko naj bi himalajska sol vsebovala joda in zato ne morem z zagotovostjo trditi

 

Seveda ima himalajska sol fuul mineralov in je bolj naravna in podobne finte, AMPAK ima premalo joda!

Vidiš Immortelle, ne želim ti soliti pameti ( ), ampak morda se z jodirano soljo to ne bi zgodilo.

 

Zakaj o tem govorim? Imam vaje v KC na oddelku za ščitnico, in zdravnica nas je opozorila, kako ljudje padajo na razne marketinške finte o naravnih soleh in

ne vem še čim... Pa razvijejo ščitnično bolezen, ker vnesejo premalo joda. Da ne omenjam, kako so te soli dražje in potem se avtomatsko misli, da so boljše.

 

Vnašanje zadostne količine joda je najboljša preventiva za zdravje ščitnice!

 

Te alge so najbrž prav super, ampak zopet - veliko dražja alternativa jodirani soli.

Za sol mi je zadnjič razlagal sodelavec, da ima doma kristal himalajske soli, namočen v vodo, da ustvari solno raztopino in z njim začini solate oziroma takšne jedi, kjer sol v zrncih draži pri prehranjevanju.

[Immortelle]

Kolikor sem brala, ima večina ljudi (tudi vsejedcev) premalo joda... Včasih so baje dodajali jod veliko stvarem (ne samo soli), potem so pa to ukinili. 

Na embalaži himalajske soli je jod na prvem mestu med sestavinami, ni pa res nič navedeno, koliko ga vsebuje.

Za vegane bi bila tudi jodirana sol po mojem premalo, prav tako pa ni dobro uživati večje količine soli... 

 

Meni se zdi kelp v prahu povsem naravna stvar (bolj kot npr. prečiščena sol z dodanim jodom). Pa tudi drag tak prah ni. Jaz sem za 250g dala 5 eur. Čeprav ima res grozen okus - kot da bi pil morsko vodo, pomešano z algami. Vzame se ga do pol žličke na dan - priporočam v kakšnem smoothiju, da se prikrije okus. Nekateri ga posujejo po solati ali dajo v juho. 

[Matilda]

Res je, preveč soli ni dobro. Problem je v tem, da se res pretirava z njo na splošno, ljudje si jo vsujejo v vsako jed že skoraj,

poleg tega pa po možnosti še pokonzumirajo veliko predelane hrane z dodano soljo.

Kakšen ščepec na dan pa se mi ne zdi problematičen, v kombinaciji z nasplošno zdravo prehrano.

Himalajska sol pa ima verjetno premalo joda in ne ščiti pred boleznimi ščitnice, zato ne nasedat in zapravit precej več denarja, kot bi ga za jodirano morsko sol.

[Frčica]

Od fanta sodelavka je zbolela na ščitnici, uporabljala pa je himalajsko sol. Se je pozdravila, ampak je pa na začetku slabo kazalo.

[Immortelle]

Čisto verjamem. Meni je himalajska sol vseeno bolj všečna kot tista navadna, ampak se zelo strinjam s tem, da ni dovolj dober vir joda.

Iron found in meat may increase your risk of heart disease, according to a new meta-analysis published in the Journal of Nutrition.

Researchers analyzed data from 21 international studies, which included 292,454 participants, for an average of ten years. Results showed heme iron (found in meat) increased risk of heart disease by 57 percent. Conversely, non-heme iron found in vegetables showed no relationship to risk or mortality from heart disease.
