Ja mähän selitin jo, miksi raffinoitua viljaa ei kannata syödä. Lue. Asia ei ole merkityksetön.
Onko jotain tutkimusta/tieteellistä tukemassa väitettäsi? Tai pikemminkin kumoamassa väitettäni - kohtuullisissa määrin merkityksetön seikka, jos suojaravinteita saa tarpeeksi.
Edellisten lähteiden luotettavuus oli melko heikkoa.
Selitit vain, että se aiheuttaa turvotusta, ärtyneisyyttä ja päänsärkyä. Lähde ja perusteet puuttuivat. Söinpäs paljon raffinoitua viljaa eikä tullut päänsärkyä, ärtyneisyyttä eikä turvotusta.
Kysy asiaa ravintoasiantuntijalta.
Voivat sanoa mitä vain, mutta ilman tieteellistä perustaa heidän väitteensä ovat merkityksettömiä. Ravintoasiantuntija on vielä melko suhteellinen käsite.
Raffinoitu vilja aiheuttaa suurelle osalle kansaa erilaisia ongelmia kehon kanssa, piste.
Kohtuullisissa määrin? Lähde?

BACKGROUND: Whole-grain foods are associated in observational studies with a lower body mass index and lower cardiovascular disease (CVD) risk. However, few clinical trials have tested whether incorporating whole grains into a hypocaloric diet increases weight loss and improves CVD risk factors. OBJECTIVE: The aim of this study was to determine whether including whole-grain foods in a hypocaloric (reduced by 500 kcal/d) diet enhances weight loss and improves CVD risk factors. DESIGN: Obese adults (25 M, 25 F) with metabolic syndrome were randomly assigned to receive dietary advice either to avoid whole-grain foods or to obtain all of their grain servings from whole grains for 12 wk. All participants were given the same dietary advice in other respects for weight loss. RESULTS: Body weight, waist circumference, and percentage body fat decreased significantly (P<0.001) in both groups over the study period, but there was a significantly (P=0.03) greater decrease in percentage body fat in the abdominal region in the whole-grain group than in the refined-grain group. C-reactive protein (CRP) decreased 38% in the whole-grain group independent of weight loss but was unchanged in the refined-grain group (P=0.01 for group x time interaction). Total, LDL, and HDL cholesterol decreased in both diet groups (P<0.05). Dietary fiber and magnesium intakes increased in the whole-grain but not the refined-grain group (P=0.007 and P<0.001, respectively, for group x time interaction). CONCLUSIONS: Both hypocaloric diets were effective means of improving CVD risk factors with moderate weight loss. There were significantly (P<0.05) greater decreases in CRP and percentage body fat in the abdominal region in participants consuming whole grains than in those consuming refined grains.

BACKGROUND: Fast food is consumed in large quantities each day. Whether there are differences in the acute metabolic response to these meals as compared to 'healthy' meals with similar composition is unknown. DESIGN: Three-way crossover. METHODS: Six overweight men were given a standard breakfast at 8:00 a.m. on each of 3 occasions, followed by 1 of 3 lunches at noon. The 3 lunches included: (1) a fast-food meal consisting of a burger, French fries and root beer sweetened with high fructose corn syrup; (2) an organic beef meal prepared with organic foods and a root beer containing sucrose, and (3) a turkey meal consisting of a turkey sandwich and granola made with organic foods and an organic orange juice. Glucose, insulin, free fatty acids, ghrelin, leptin, triglycerides, LDL-cholesterol and HDL-cholesterol were measured at 30-min intervals over 6 h. Salivary cortisol was measured after lunch. RESULTS: Total fat, protein and energy content were similar in the 3 meals, but the fatty acid content differed. The fast-food meal had more myristic (C14:0), palmitic (C16:0), stearic (C18:0) and trans fatty acids (C18:1) than the other 2 meals. The pattern of nutrient and hormonal response was similar for a given subject to each of the 3 meals. The only statistically significant acute difference observed was a decrease in the AUC of LDL cholesterol after the organic beef meal relative to that for the other two meals. Other metabolic responses were not different. CONCLUSION: LDL-cholesterol decreased more with the organic beef meal which had lesser amounts of saturated and trans fatty acids than in the fast-food beef meal. Copyright 2007 S. Karger AG, Basel.

Cereals are considered an important source of nutrients both in human and animal nourishment. In this paper nutritional value of brown rice is compared to that of white rice in relation to nutrients. Results show that despite higher nutrients contents of brown rice compared to white rice, experimental datas does not provide evidence that the brown rice diet is better than the diet based on white rice. Possible antinutricional factors present in brown rice have adverse effects on bioavailability of this cereal nutrients.

With the increasing prevalence of obesity in the United Kingdom, the search for an effective weight reducing diet is a priority in helping to reverse this trend. A 12-week dietary intervention study was carried out to test the effectiveness of an energy-restricted, low-fat, sugar-containing diet on weight loss in sedentary overweight men. The study also aimed to assess eating behaviour, to measure change in attitude towards sugar-containing foods and to measure the impact of the study on perceived quality of life. Subjects were recruited from three UK cities; Edinburgh, Birmingham and London. Seventy-six men, aged between 25 and 60 years, completed the study. Baseline diets were assessed by a 7-day diet diary. Compliance to the subsequent dietary advice was measured on four occasions post intervention, by 4-day diaries. Measures of body weight status were also monitored. Eating behaviour, attitudes towards sugar-containing foods and quality of life were assessed by questionnaire. Significant reductions in body weight (5.2%), body fat (11.2%) and waist:hip ratio (3%) were observed following reported dietary changes that included a reduction in reported energy intake of 3.2 MJ/day (770 kcal/day), a reduction in the percent energy from fat (from 38.1% to 26.2%), an increase in the percent energy from total carbohydrate (from 44.4% to 54%) and from protein (from 17.3% to 20.6%). Subjects scored relatively highly for dietary restraint and emotional eating, and were strongly influenced by external eating cues. On completion of the 12-week study, subjects had a more positive attitude towards sugar-containing foods and perceived an improved quality of life. It is concluded, therefore, that including sugar-containing foods in a weight-reducing diet may be an effective strategy to achieve a palatable, low-fat, high-carbohydrate diet, which promotes weight loss in overweight individuals.

In response to evidence linking obesity and high amounts of dietary fat, the food industry has developed numerous reduced-fat and nonfat food items. These items frequently derive a relatively large percentage of their energy from sugars and the effect of these sugars on weight regulation is not well known. We studied the comparative effects of high- and low-sucrose, low-fat, hypoenergetic diets on a variety of metabolic and behavioral indexes in a 6-wk weight-loss program. Both diets contained approximately 4606 kJ energy/d with 11% of energy as fat, 19% as protein, and 71% as carbohydrate. The high-sucrose diet contained 43% of the total daily energy intake as sucrose; the low-sucrose diet contained 4% of the total daily energy intake as sucrose. Twenty women aged 40.6 +/- 8.2 y (mean +/- SD) with a body mass index (in kg/m2) of 35.93 +/- 4.8 consumed the high-sucrose diet; 22 women aged 40.3 +/- 7.3 y with a body mass index of 34.93 +/- 4.4 consumed the low-sucrose diet. Mixed-design analysis of variance showed a main effect of time (P < 0.01), with both diet groups showing decreases in weight, blood pressure, resting energy expenditure, percentage body fat, free triiodothyronine (FT3), urinary norepinephrine, and plasma lipids. Small but significant interactions were found between group and time in total cholesterol (P = 0.009) and low-density lipoprotein (LDL) (P = 0.01). Both groups showed decreases in depression, hunger, and negative mood, and increases in vigilance and positive mood with time (P < 0.01). Results showed that a high sucrose content in a hypoenergetic, low-fat diet did not adversely affect weight loss, metabolism, plasma lipids, or emotional affect.
Wat!! Dieetti joka siälsi peräti 43% kokonaiskaloreista sokeria ei ollut haitallinen painonpudotukselle, aineenvaihdunnalle, veriarvoille tai mielialalle/tunne-elämälle or whatever. Sotii hieman väitteitäsi vastaan eikö?

The long-term impact of dietary carbohydrate type, in particular sucrose, on insulin resistance and the development of diabetes and atherosclerosis is not established. Current guidelines for the healthy population advise restriction of sucrose intake. We investigated the effect of high- versus low-sucrose diet (25 vs. 10%, respectively, of total energy intake) in 13 healthy subjects aged 33 +/- 3 years (mean +/- SE), BMI 26.6 +/- 0.9 kg/m(2), in a randomized crossover design with sequential 6-week dietary interventions separated by a 4-week washout. Weight maintenance, eucaloric diets with identical macronutrient profiles and fiber content were designed. All food was weighed and distributed. Insulin action was assessed using a two-step euglycemic clamp; glycemic profiles were assessed by the continuous glucose monitoring system and vascular compliance by pulse-wave analysis. There was no change in weight across the study. Peripheral glucose uptake and suppression of endogenous glucose production were similar after each diet. Glycemic profiles and measures of vascular compliance did not change. A rise in total and LDL cholesterol was observed. In this study, a high-sucrose intake as part of an eucaloric, weight-maintaining diet had no detrimental effect on insulin sensitivity, glycemic profiles, or measures of vascular compliance in healthy nondiabetic subjects.
Vaikka korkeasokerinen dieetti sisälsi kokonaiskaloreista peräti neljäsosan sokereita, se ei ollut siitä huolimatta haitallisempi insuliiniherkkyydelle, glykeemia-arvoille tai verisuonitautiarvoille kuin dieetti, joka sisälsi saman verran sokeria kuin mitä useimmat ravitsemusasiantuntijat suosittelevat tai pitävät kohtuullisena.
Luuletko todella, että jos päivän suojaravinnetavoitteet on saavutettu, raffinoidulla viljalla on suurta merkitystä? Ja aiemmin mainitsemissa ruoissa on ravinteita, vaikka kaikkia ei yhtä paljon kuin täysjyvätuotteissa. Tarkoittaako tämä, että pitää aina syödä vain ruokaa, joissa on ravinteita koska muuten niistä on haittaa? EI. Mikä on se vaikutusmekanismi, joka tekisi noista tuotteista niin paljon huonomman, että niitä ei saisi syödä. Olettaen, ettö mistään suojaravinteesta ei tule puutetta, miksi/miten niistä olisi haittaa? Ja ennen kaikkea, miksi tiede ei tue kantaasi?
