I"m sure that for you they do, For me and a few others http://www.mentalhealth.org.uk/html/...ec_summary.pdf Complex carbohydrates as well as certain food components such as folic acid, omega-3 fatty acids, selenium and tryptophan are thought to decrease the symptoms of depression.

Department of Psychology, University of Wales Swansea, Singleton Park, Swansea SA2 8PP, UK. A series of studies have reported that a high carbohydrate meal, or diets high in carbohydrate, were associated with feeling less energetic. However, after a drink containing pure sugar most studies report no effect. Meals almost exclusively carbohydrate increase the availability of tryptophan and hence serotonin synthesis in the brain, however, a small amount of protein blocks this mechanism making it an uncommon response. In many individuals, poor mood stimulates the eating of palatable high carbohydrate/high fat foods that stimulate the release of endorphins. There is a tendency for those with lower blood glucose, when performing cognitively demanding tasks, to report poorer mood. In a range of situations an association between a tendency for blood glucose levels to fall rapidly, and irritability, has been found. Differences in the ability to control blood glucose levels influence the association between carbohydrate intake and mood. There is a need in future research to contrast the impact of carbohydrate on mood in those distinguished because of their pre-existing psychological and physiological functioning. Publication Types: Review PMID: 12034132 [PubMed - indexed for MEDLINE] === http://www.ncbi.nlm.nih.gov/entrez/q...80&query_hl=50 1: Public Health Nutr. 1999 Sep;2(3A):403-9. The effects of nutrients on mood. Benton D, Donohoe RT. Department of Psychology, University of Wales Swansea, Swansea, UK. A recent major theory was that a meal high in carbohydrate increased the rate that tryptophan enters the brain, leading to an increase in the level of the neurotransmitter serotonin that modulates mood. Although such a mechanism may be important under laboratory conditions it is unlikely to be of significance following the eating of any typical meal. As little as 2-4% of the calories of a meal as protein will prevent an increased availability of tryptophan. Arguably the food with the greatest impact on mood is chocolate. Those who crave chocolate tend to do so when they feel emotionally low. There have been a series of suggestions that chocolate's mood elevating properties reflect 'drug-like' constituents including anandamines, caffeine, phenylethylamine and magnesium. However, the levels of these substances are so low as to preclude such influences. As all palatable foods stimulate endorphin release in the brain this is the most likely mechanism to account for the elevation of mood. A deficiency of many vitamins is associated with psychological symptoms. In some elderly patients folate deficiency is associated with depression. In four double-blind studies an improvement in thiamine status was associated with improved mood. Iron deficiency anaemia is common, particularly in women, and is associated with apathy, depression and rapid fatigue when exercising. Publication Types: Review PMID: 10610080 [PubMed - indexed for MEDLINE] === http://www.ncbi.nlm.nih.gov/entrez/q...77&query_hl=38 1: Asia Pac J Clin Nutr. 2005;14 Suppl:S87. Diet and mood state. Worsley A, Nowson CA, Margerison C, Jorna MK. School of Exercise and Nutrition Sciences, Deakin University, Burwood, Victoria, Australia. Background - There is some limited data indicating that dietary intake may alter mood states, but most of this is anecdotal. A number of dietary factors have been associated with reduction in blood pressure, which could, in part be related to positive effects on general mood states. Objective - To determine if urinary excretion of particular minerals is associated with different mood states and if changing to one of the test diets DASH type diet (high fruits, vegetables and low fat dairy products) (OZDASH), a low salt, high fruit/vegetable diet (LNAHK) or a high calcium diet (HC) has an effect on mood state. Design - Subjects completed an abbreviated 37-item version of the Profile of Mood States weekly throughout a 14-week dietary study. Each person consumed two different types of diets for 4 weeks, preceded by a 2 week control diet and performed 24-hr urine collections fortnightly. Outcomes - For the 62 subjects who completed all tasks, throughout the study, there was a significant inverse association with 24-urinary excretion of calcium and potassium with depression (r= -0.26 P 0.05, r= -0.25 P 0.05), calcium and fatigue (r= -0.29 P 0.01) and a positive association for sodium and vigour (r=0.39 P =0.01). When assessing the change in urinary electrolytes, moving from the control diet to one of the test diets, there was a significant reduction in tension and anger with all diets (OZDASH (n=93) P 0.05, LNAHK (n=43) P 0.01 and HC (n=47) P 0.01), a reduction in fatigue on the OZDASH and HC (P 0.01), a reduction in confusion on the OZDASH and LNAHK (P 0.05) and a reduction in depression on the HC diet (P 0.05) there were no differences in the vigour scores on any diet. The HC diet had the lowest anger and depression scores and both the OZDASH and HC diet reported lower fatigue scores. Conclusion - These findings strongly suggest that mood is related to mineral metabolism. Dietary change may affect mood state, particularly the inverse association of calcium and potassium to depression/fatigue. These findings should be treated with caution but strongly suggest further replication studies are warranted.

Ok, then avoid carbs, if that happens even with low-GI foods such as pumpernickel rye bread or pasta. [...] Whole grains are also rather satiating, by the way, more than some other foods with the same caloric content. Not from my experience.

For starters, for their content in soluble fiber, that helps prevent diabetes and lower cholesterol, etc. Then, for their phytates, saponines, agglutinins, some polysaccharides, protease inhibitors, thousands of different polyphenols, and so on...".

Only veggies, never grains? What a bore! :-P Actually, there's a lot more variety in taste with veggies than grains. Grains tend to be relatively bland and primarily used as fillers in cooking. Again, why should we chose one or the other when we can have both. There's more variety in taste with veggies *and* grains than veggies alone. Sometimes grains are reintroduced later sometimes not depending on the individual and the plan. As a result, any study posted to ASDLC tat discusses how healthy whole grains are needs to compare them *against veggies*. Why? They are different foods, you can have both. Everyone can't have both. As noted previously in this thread, I am diabetic and cannot tolerate grains (or even legumes except in tiny servings). My bg will not remain stable and my health will deteriorate if I eat grain. Fair enough. If you cannot tollerate grains, you have a very good reason not to eat them! But that doesn't apply to everyone. On the other hand, my husband is not diabetic, and can and does eat whole grains, Do they affect him in some way? as well as a lot more fruit than I do (I stick to small servings of melon and berries only). Other people do not tolerate grains because of gluten intolerance or other allergies. There are also people who avoid other foods for special reasons. For those who can eat both, sure... eat both. Agreed. But... the question of whether there are nutrients missing in a diet without grain is relevant to a lot of folks who cannot tolerate grain for one reason or another. I see your point. I don't know whether there are nutrients missing in a diet without grain. I would tend to doubt that, provided the diet is varied enough. I was not saying grains are "essential", though. I believe there is hardly a truely "essential" food. Think of the vegetarians who can live without meat, fish, cheese, eggs... Still, why should we? Show me a study that has one group eating wheat, corn, rice and occasional oats to the exclusion of veggies, and another group eating asparagus, cauliflower, zucchini and occasional turnips to the exclusion of grain. Then you will have shown me a study that actually discusses if grains are really heatlhy. I doubt that there are "healthy" and "unhealthy" foods (provided we consider real, natural, fresh foods, not toxic stuff). Again, it depends on the individual. Peanuts are a "healthy" food for me and my husband, but will kill other people. Biochemistry is not "one-size-fits-all." And it also depends on what that individual does: his or her life-style... I believe there are healthy and unhealthy *quantities*. Eat more veggies and less grains, and be happy! Agreed. 1) Wolk A, Manson JE, Stampfer MJ, et al. Long-term intake of dietary fiber and decreased risk of coronary heart disease among women. JAMA 1999;281:1998-2004.[Online] Discusses fiber intake. Since fiber can come from either veggies or grain, this study fails to show that eating plenty of veggies and zero grain is any sort of problem. A dull diet *is* a problem, for instance. I don't really think wheat berries or oats add much excitement though. They're relatively bland foods. True, but that's precisely why they always come in good company, oats with milk and nuts in a muesli, for instance... other grains with tomatoes, veggies, oil, olives, cheese, eggs, meat, fish... When you want something flavorful... you think peppers, onions, garlic, tomatoes, spinach, chard, kale, parsley, basil, shallots, leeks, etc. Since most low carb plans are high-veggie and low-or-no-grain, this study is utterly irrelevant to demonstrating that grain is better than the alternative. Try and think the other way round.... Why should we restrict our diet to a few foods when we can enjoy many? Many can't though. "Beat"? Do you think they are alternatives, only veggies or only grains? Well, the discussion began about which nutrients are found in grains that are not in veggies. Ok, but then someone argued that grains are bad for everyone, and that whole grains are just "less bad". So far... the veggies *have* won. For starters, why a competition? I believe I can be healthy without whole grains in my diet. I do *not* believe that my hubsand, who does eat grain, can be healthy without vegetables though. I read the titles of the rest and there isn't any sign that one of them is a meaningfull study. Yeah, whole grains are less bad than junk refined grains, so what? Are you saying that whole grains are "bad" for you (even if "less bad")? Why? From a nutrition standpoint, whole grains contain very little nutrients for the kilocalorie. Well, they have fiber, and some vitamins and minerals. When they come with legumes, they even give some protein. Veggies have fiber too (and vitamins and minerals of course), but I am not sure whether it's the same kind of fiber. Well there's only two kinds and they're both good. Besides, I believe grains have a positive effect on mood. I"m sure that for you they do, but for many people they lead to blood sugar spikes and bad moods. Hence, they are primarily a "filler" food. Yes, and a not so expensive one. Whole grains are also rather satiating, by the way, more than some other foods with the same caloric content. Not from my experience. And fiber and protein are far more sating. Their primary "goodness" nutritionally is for those who are not getting enough kilocalories from other foods. And they are bad if you are a couch potato and you overeat... [the same applies for other caloric foods, by the way] But still, why are grains "bad" as such? Calorie to nutrient ratio. For some people who are insulin resistant and 'carb addicts" grains lead to trouble. Some people can eat them just fine. As far as culinary use, what they add to cooking is primarily texture, gluten being a particularly good example of that. Well, I can do without grains, if I want... but on the long run I get fed up! Eat grains if you want to, but they aren't necessarily better for you than another diet. *** Free account sponsored by SecureIX.com *** *** Encrypt your Internet usage with a free VPN account from http://www.SecureIX.com *** |

He doesn't eat as much carb as most people, because I do most of the cooking and can't eat it myself. But... I accomodate him. Heck, I even bake bread from scratch (*really* from scratch, where step one is hand-grinding the wheat berries). A few days back, I made myself a big pot of soup, made with italian sausage, which he doesn't care for. So... I made him a batch of scalloped potatoes with ham. But mostly, we eat the same emals... and since I restrict carbs, he doesn't eat much carb either. For instance, he has discovered that rice doesn't add anything to stirfry, just dilutes the flavors, so I quit bothering to make some on the side for him.. But... the question of whether there are nutrients missing in a diet without grain is relevant to a lot of folks who cannot tolerate grain for one reason or another. I see your point. I don't know whether there are nutrients missing in a diet without grain. I would tend to doubt that, provided the diet is varied enough. I was not saying grains are "essential", though. I believe there is hardly a truely "essential" food. Think of the vegetarians who can live without meat, fish, cheese, eggs... Still, why should we? It seems to me that in comparison to the time that I ate grain regularly, I eat a *lot* more veggies now. Course, that is how *I* low-carb. You can low-carb in an unhealthy manner too. For instance, my daughter was vegetarian for several years for ethical reasons... and primarily ate starch. She just doesn't care for vegetables much, which is an obvious disadvantage for a vegetarian. You can do *any* diet in a healthy way or an unhealthy way. A dull diet *is* a problem, for instance. I don't really think wheat berries or oats add much excitement though. They're relatively bland foods. True, but that's precisely why they always come in good company, oats with milk and nuts in a muesli, for instance... other grains with tomatoes, veggies, oil, olives, cheese, eggs, meat, fish... Because I have to limit grains, I find foods with them included taste "diluted" to me now. As noted, even my husband, whom had no problems with grains, is sorta finding the same with a lot of dishes. Noodles don't actually add anything to soup. I had a bite of his scalloped potatoes, checking to see if they were cooked through. Really... boring. I'd rather have had the same ham cooked up with a mess of kale. Well, the discussion began about which nutrients are found in grains that are not in veggies. Ok, but then someone argued that grains are bad for everyone, and that whole grains are just "less bad". I have not argued that, myself. I think grains are bad for a lot of people, likely more folks than even know they have issues with grain, but not *everybody.* There are certainly individual differences in what is the best diet for each individual, based on individual biochemistry. From a nutrition standpoint, whole grains contain very little nutrients for the kilocalorie. Well, they have fiber, and some vitamins and minerals. When they come with legumes, they even give some protein. The protein tends to be the problem for a lot of folks. Grain proteins are what cause allergic reactions in those prone to them. Besides, I believe grains have a positive effect on mood. They can raise serotonin levels in normal folks. However, for those with problems metabolizing sugar, such as myself, mood swings from unstable blood sugar are much more severe than a potential lowering of serotonin. So again, it depends on the individual. Whole grains are also rather satiating, by the way, more than some other foods with the same caloric content. Here, I would disagree, primarily based on personal experience. I assume you are not diabetic, and therefore have never experienced ravenous, uncontrollable hunger, within an hour of eating a full meal. Grains, and other carb-heavy foods, do that to me. I'm almost immediatly starving as soon as I eat them. Unstable bg is experienced as severe hunger. There's lots of fuel in your blood, but it doesn't get into your cells... so you are literally starving at a cellular level. A lot of folks whom are not yet frankly diabetic are eating themselves towards the full-blown disease because of that specific reaction to carbs. Some folks have likened it to an addiction, because it does feel that uncontrollable. The bulk of my diet by mass or volume is vegetables, but because vegetables are very low calorie, most of my kilocalories are from fat. I average around 1400-1600 kilocalories per day. That is *without* limiting myself in any way, it's just what I eat if there are few carbs in my diet. But with carbs in my diet... I can go through that many kilocalories in a few hours. Their primary "goodness" nutritionally is for those who are not getting enough kilocalories from other foods. And they are bad if you are a couch potato and you overeat... [the same applies for other caloric foods, by the way] But still, why are grains "bad" as such? Well, I find them "bad" the same way I find cat food "bad." It's perfectly good food for others, but it's not food for *me*. To me, grains are not edible. To me, grains equal high bg, mood swings, lethargy and depression. Continuing on grains would lead to blindness, amputation, organ failure and premature death. So, to me, grain is poison. Note... I am not saying grains are poison. I feed them to my husband and I'm actually pretty fond of the guy. But... they are poison to *me* same as peanuts are poison to those with a severe allergy to peanuts. |
