Overall breast cancer incidence rates for resident Japanese-Americans are somewhat lower (103/100,000) (2) than the national U.S. average (118/100,000) (3). Urine volume was measured and sample aliquots were stored at −20°C until the end of the study and then at −80°C until analyses. Finally, our estimate of seaweed dose was done post hoc, rather than prospectively, and needs to be explored further. Seaweeds are typically part of most Japanese diets (12). Take your nori seaweed and place it shiny side down on a bamboo mat. Seaweeds also have a higher binding affinity for estrogens than do land plant fibers (15). Nori seaweed is the most common edible seaweed produced worldwide. And research shows eating seaweed builds a strong skeleton. A person with Celiac disease may react to the wheat that may be present in soy sauce, but not to the MSG in the product. Our study is limited by its small size, which limits statistical power, as well as the uniform ethnic racial/ethnic composition typical of the population of central Massachusetts. It goes without saying that seaweed is an indispensable ingredient for making sushi, without which your sushi will not be the same. Although seaweed is only a seemingly small part of a Japanese diet, in seaweed-naive women, it lowered serum estrogens, increased favorable estrogen metabolism, and enhanced soy-stimulated conversion of phytoestrogens. Sekiya M, Funahashi H, Tsukamura K, Sekiya M, Yokoi K, Hayashi H, Shibata A, Hayashi T, Nishikawa M, et al. Leave a one-inch border on the edge of the seaweed that is facing away from you. The lower limit of detection for SHBG using this kit was 3 nmol/L. Seven declined for lack of interest in the study protocol and 8 were excluded on the basis of thyroid-related issues [2 for abnormal serum thyroid stimulating hormone concentrations, 3 for high thyroid peroxidase antibodies (>191 U/L), and 3 for current or recent thyroid medications]. Likely mechanisms include differences in diet, especially soy consumption, and estrogen metabolism. Finally – most have soy sauce in them which typically contains wheat unless it's gluten-free Tamari. The collection jugs were stored in their refrigerators until the clinic visit. Three values for 16αOHE1 were below the lower limit of test validity (0.5 μg/L) and were set to 0.4 μg/L for statistical analysis. Breast cancer incidence rates for Japanese women who migrate to the US rise dramatically after 10 y, increasing from 20/100,000 to 35/100,000 (1). Green algae, whose fatty acid make-up is the closest to higher plants, have a much higher oleic and alpha-linoleic acid content. We thank Larch Hanson and Shep Erhart for their assistance in identifying and collecting the seaweed. The lower limit of detection for E1 was 4.4 pmoI/L. Urinary phytoestrogen excretion in healthy postmenopausal women after placebo, seaweed, soy, and SeaSoy treatments1. The Wellness Mama Cookbook and The Wellness Mama 5-Step Lifestyle Detox. Consumption of soy foods is th… Analyses of urinary 2-hydroxyestrogen (2-OHE) and 16α-hydroxyestrone (16αOHE1) levels were completed at the Hackensack University Medical Center in a single batch, using the competitive solid-phase enzyme immunoassay from IMMUNA CARE (24). Seaweed is chock-full of vitamins, minerals, and fiber, and can be tasty. Japanese women who consume a traditional diet have 2- to 3-fold higher fecal excretion rates of E2 (9), strongly suggesting that dietary factors and their effect on colonic bacteria may be critical in understanding differences in international breast cancer rates. Seaweed supplementation was associated with an inverse correlation between seaweed dose (mg/kg body weight) and serum E2 and was linear across the range of weights (E2 change seaweed-placebo = 0.28 × dose – 42.8; r = 0.70; P = 0.003) (Fig. In comparison to seaweed, soy paper is a better option that doesn’t have the sea smell associated with sushi. Urine volume was measured for the entire 48-h collection and divided by 2 to obtain 24-h volume estimates used in the analyses. In the category of vegetables, we included whole vegetable products in the Top 10 list. A dose of 2 mg isoflavones/kg body weight was calculated for each woman. Estrone (E1), E2, and sex hormone-binding globulin (SHBG) were analyzed at the University of Massachusetts laboratory of Dr. Christopher Longcope. Sue Druker provided excellent project coordination. Seaweed VS Soy Paper. Urinary iodine was used to confirm adherence to the protocol during seaweed supplement periods. Pour cheese sauce over the pasta and add in the seaweed and peas. Individual models were run for 12 hormone-related dependent variables: serum measures of E1, E2, and SHBG, urinary estrogen metabolites 2-OHE, 16αOHE1, and the ratio of 2-hydroxyestrogen:16α-hydroxyestrone (2:16 ratio), and 2 groups of urinary phytoestrogens, the isoflavones: genistein, daidzein, glycitein, O-DMA, equol, and the lignans: secoisolariciresinol, matairesinol, enterolactone, and enterodiol. Recipes for Soy Sauce Alternatives: I have not tried any of these recipes yet but I’m compiling them here for future reference. Wakame contains 2.1 milligrams of iron per 100 grams. Reserve at least ½ cup of the pasta water, and then strain the pasta. I have now eaten nori-wrapped sushi and not hated it. Have you ever had sushi with soy paper instead of seaweed? Two large epidemiologic studies have reported a significant dose-response relationship between higher antibiotic use and breast cancer risk (10,11). Trock BJ, Hilakivi-Clarke L, Clarke R. Rock CL, Flatt S, Laughlin G, Gold EB, Thomson CA, Natarajan L, Jones LA, Caan BJ, Stefanick ML, et al. Linear contrasts were used to test for the main effects and the interaction effects. Most traditional seaweed salad recipes rely heavily on soy sauce (traditional soy sauce contains gluten, plus soy itself is definitely not considered Paleo!) There are many benefits of seaweed and it is a very nutritious food. They concluded that most seaweed products are safe with respect to WHO guidelines. Correlation between seaweed dose and change in serum E2 concentrations after seaweed treatment compared with placebo in healthy postmenopausal women (n = 15) (y = 0.28 × dose − 42.8; r = 0.70; P = 0.003). After a 3-wk washout period, participants were crossed over to the alternate supplement schedule. U.S. Cancer Statistics Working Group. Seaweed alone did not affect these phytoestrogens. SHBG decreased significantly after soy supplementation. Equol producers were identified using the log10 of the equol:daidzein ratio, where a value > −1.75 was classified as an equol producer (27). In our small sample of 5 equol producers and 10 equol nonproducers, the results were not significantly different. Half a sheet is enough to make one set of rolls, which gets cut into 6 or 8 pieces. Ozasa K, Nakao M, Watanabe Y, Hayashi K, Miki T, Mikami K, Mori M, Sakauchi F, Washio M, et al. Therefore, her values for SeaSoy are missing in all analyses. In vivo studies of a similar dietary seaweed (Undaria) report an 80% reduction in production of colonic β-d-glucuronidase (14), the enzyme needed to deconjugate E2 prior to enterohepatic recirculation. Prior to the first clinic visit, all eligible participants were assigned to a treatment group using a computer-generated random number table. Goitrogens found in soy (and other vegetables) only seem to cause thyroid problems when iodine intake is low and soy intake is high. Seaweed is less than 1 calories per sheet. He added the seaweed and, a few minutes later, dried ramen noodles. Demographic variables in healthy postmenopausal women at baseline by disease status1. In general, seaweed harvested from the Korean coast is quite safe. For SeaSoy, the first P-value is for the test relative to placebo and the second is the test for an interaction. However, the magnitude of the changes for women who were equol producers (n = 5) were more impressive, with SeaSoy associated with a 58% increase in 2-OHE, a 40% decrease in 16αOHE1, and a 315% increase in the 2:16 ratio. Supported by the Susan G. Komen Foundation (grant 9735) and the U.S. Army Medical Research and Materiel Command under DAMD 17-98-1-8207. Women were recruited by word of mouth, physician referrals, and through responses to a newspaper article. Women collected 48-h urine specimens immediately preceding each visit. Soy … Nori seaweed nutrition facts. J Chromatogr B Analyt Technol Biomed Life Sci. Kathyrn Edmiston, Michael Wertheimer, and Mary Costanza for their helpful comments on study design and patient recruitment, and Charlene Franz for her work on serum hormone analysis. Scientists have categorized types of seaweed into different categories based on their pigments, cell structure, and other traits. Since there are just so many healthy nutrients that lie in seaweed from omega 3 to magnesium. Does Seaweed Have Too Much Iodine? Salt (or soy sauce) to taste and serve! Urinary estrogen metabolite excretion in healthy postmenopausal women after placebo, seaweed, soy, and SeaSoy treatments1. I am so excited about this b/c I never liked sushi b/c the texture of the seaweed. Seaweed snacks are growing in popularity due to manufacturers’ health claims. Consumption of soy foods is the most commonly identified dietary difference, although recent meta-analyses suggest that eating soy foods may lower breast cancer risk by only ∼20% (4,5). We excluded dried/dehydrated products from the Top 10. To test the primary study hypotheses that seaweed influences estrogen metabolism and that the combination of seaweed plus soy (SeaSoy) would have a synergistic effect (the main effects for seaweed and soy, and a seaweed × soy interaction), we conducted a repeated-measures ANOVA using Proc Mixed in SAS. The study utilized an unbiased, randomized, placebo-controlled crossover design. Cybele Pascal has shared a recipe online on how to make a top 8 allergen free soy sauce recipe using beef stock, seaweed, cider vinegar, garlic, ginger, and pepper. E1 was measured by RIA using kits provided by Diagnostic Systems Laboratories (DSL-8700). Linear contrasts were created in Proc Mixed to test, relative to placebo, for the main effects of seaweed, soy, and SeaSoy, as well as the interaction between seaweed and soy. The University of Massachusetts Medical School Institutional Review Board approved the study. and sesame oil for flavor. Inclusion criteria were: being postmenopausal (self-reported cessation of menstruation > 1 y prior to enrollment); no allergies to seaweed, soy, shellfish, or iodine; no current use of tobacco; no thyroid dysfunction or treatment within the previous 5 y; negative thyroid peroxidase antibodies as determined by screening; no hormone replacement therapy or for breast cancer survivors, no chemotherapy or radiation treatments within the preceding 6 mo, no history of cancer (other than breast cancer); no current gastrointestinal disorders or diabetes; omnivorous eating habits, including meat and dairy products > twice/wk; and no oral antibiotics, iodine-containing medications, or corticosteroids treatment within the previous 3 mo.

Grams is a measure of weight. Samples from a given individual were always assayed in the same batch. No specific mechanism was identified. For the 3 main effects, the difference was calculated separately between the LSMeans for each treatment and placebo. The phytoestrogens were measured as total amount excreted per day. Share on Pinterest. Intra- and interassay CV were 2.1 and 5.9%, respectively. Although 2-OHE1 is the predominant C-2 metabolite found in women, the sum of both metabolites are measured (25). Although there were also similar declines in E1 and SHBG with increasing seaweed dose, none of these were significant. Intra- and interassay CV were 3.5 and 4.1%, respectively. Wakame salad (Lisa Landers) The Promise of Prevention. Does antibacterial treatment for urinary tract infection contribute to the risk of breast cancer? Based on data from our study, the effective E2-lowering dose of seaweed would be ∼75 mg/kg body weight. Future studies should include direct measurement of changes in colonic bacteria. Brown seaweeds have no land equivalents in terms of their specific components of fiber (alginate), primary carotenoid (fucoxanthin), sulfated polysaccharides (fucoidan and laminarin), and polyphenol defense compounds, each of which have shown strong anticarcinogenic properties (18–20). An eye-catching deep purple sushi rolls you must have seen in any Japanese restaurants is actually the red nori algae that grows proficiently in the intertidal sea zones in many temperate areas around the world.. Scientific name: Prophyra spp., Rhodophyceae. Nori is the type of seaweed that is commonly used in sushi rolls. As seaweed is rich in iodine, too much of it over a prolonged period of time can negatively affect the functions of the thyroid gland and may lead to thyroid dysfunction. It contained 1.43 mg/g total aglycone isoflavone equivalents. Studies of Japanese postmenopausal breast cancer survivors have serum levels near the lower level of detection (8) compared with nearly 3-fold higher levels for U.S. postmenopausal breast cancer survivors (7). However, some species such as Hijiki and H. fusiforme may be high in arsenic (. The protein present in some seaweeds , such as spirulina and chlorella, contain all of the essential amino acids. The antibiotic properties of seaweeds may also influence population dynamics of colon bacteria, favoring healthy bacteria (34). Author disclosures: J. Teas, T. G. Hurley, J. R. Hebert, A. To test for the interaction effect of SeaSoy, the difference was calculated as the LSMean for SeaSoy – the sum of the LSMeans for seaweed and soy. Iodine can be obtained naturally from foods such as sea salt and sea vegetables (aka seaweed, e.g. Subsequently, 3 women dropped out of the study due to allergic reactions (rash and reactivated esophageal reflux) to seaweed (2) and naturopath advice (1). It is important to note that C-2 antibody is 100% cross specific for 2-OHE1 as well as 2-OHE2. Copyright © 2020 American Society for Nutrition. An indirect mechanism for reducing serum E2 includes changes in the bacterial ecology of the colon. This might explain why most Japanese and other Asian people can consume seaweed without any problem . All samples were assayed in duplicate and the mean value was used for analysis. Urinary equol excretion has been generally reported to be protective against breast cancer. For a more heart-friendly seaweed salad, prepare it yourself using low-sodium soy … This Honey Soy Salmon with Seaweed Salad is perfect if you’re following a calorie controlled diet, and fits well with any one of the major diet plans such as Weight Watchers. Apply a thin layer of rice on the nori. In this subset of women, both equol and O-DMA increased with soy supplementation and even more with SeaSoy, suggesting a biomagnification of specific colon bacteria. Bread…. The California rolls also have seaweed but it is hidden inside to appeal the westerners. To ensure the laboratory analysis was conducted without knowledge of treatments, each patient at each clinic visit was assigned a unique identification number. Adding seaweed to a meal is an easy way to do that. Only 1 dietary study has included seaweed in its assessment of food variables associated with urinary phytoestrogen excretion and it did report a significant association between seaweed intake and equol production (32). No fillers or binders were added to the seaweed or placebo powder. Fifteen healthy postmenopausal women participated in this double-blind trial of seaweed supplementation with soy challenge. Many seaweeds contain anti-inflammatory and anti-microbial agents. Each type of … Sitemap, The Benefits of Seaweed (And When To Avoid It), Benefits of Onions: A Surefire Home Remedy in Your Kitchen, Too Much Iodine Can Cause Thyroid Problems, Digestive Problems from Seaweed Carbohydrates and Fibers, Radioactive Levels from Fukushima Radiation, develop thyroid problems from too much iodine. For the 5 equol excretors, soy increased urinary equol excretion (P = 0.0001); the combination of SeaSoy further increased equol excretion by 58% (P = 0.0001). A soy challenge was used to more closely approximate the diet consumed by Japanese women. In Japan, between 55 and 60% of the population produce equol after consuming soy foods, compared with only ∼33% of people living in Western countries (27). Seaweed is also considered to have anti-obesity effects. In vitro and in vivo studies of seaweed have reported increased water retention and fecal bulk and decreased colon transit time (28). Intra- and interassay CV were 5.9 and 7.7%, respectively. These data support the hypothesis that lifestyle differences, especially dietary changes and related gene-nutrient interactions, are important in breast cancer susceptibility. Many in vitro and in vivo studies have demonstrated anticarcinogenic activities of seaweeds, especially against breast cancer. What kind of seaweed is used for sushi? The 16α-OHE1 pathway is highly toxic, associated with genotoxic damage, stimulation of growth of anchorage independent breast cancer cells, irreversibly binding to estrogen receptors, and persistent hyperproliferation. A more detailed analysis of changes in iodine and thyroid hormone levels has been presented elsewhere (22). It was chosen for its low-iodine (95 μg/g) concentration (22). The effect of Fucus vesiculosus, an edible brown seaweed, upon menstrual cycle length and hormonal status in three pre-menopausal women: a case report, Brown kelp modulates endocrine hormones in female Sprague-Dawley rats and in human luteinized granulosa cells, Antiproliferative effect of neoxanthin and fucoxanthin on cultured cells, Intracellular signaling in the induction of apoptosis cancer cell line by water extract of Mekabu, A multi-gene molecular investigation of the kelp (Laminariales, Phaeophyceae) supports substantial taxonomic re-organization, Seaweed and soy: companion foods in Asian cuisine and their effects on thyroid function in American women. Before you jump on this trend, weigh the seaweed benefits and side effects. As a guide, an average man needs around 2,500kcal (10,500kJ) a day to maintain a healthy body weight. The groups (or phyta) of seaweed that are commonly consumed include: ... soy milk, and cruciferous vegetables. Results are presented as least square means (LSMeans; these are the covariate-adjusted means obtained from the mixed model) with 95% CI. Kuda T, Yano T, Matsuda N, Nishizawa M.

These estimates are consistent with the 5–7 g/d estimated effective seaweed dose proposed by in vivo seaweed chemoprevention studies of mammary carcinoma (19,20). United States Cancer Statistics: 1999–2004 incidence and mortality Web-based report. There was an inverse correlation between seaweed dose (mg/kg body weight) and serum estradiol (E2) (seaweed-placebo = y = 0.28 × dose − 42.8; r = 0.70; P = 0.003), which was linear across the range of weights. First off, not all preparations of seaweed have a strong taste. Miyoshi Y, Tanji Y, Taguchi T, Tamaki Y, Noguchi S. Adlercreutz H, Gorbach SL, Goldin BR, Woods MN, Dwyer JT, Hamalainen E.

Fukuda S, Saito H, Nakaji S, Yamada M, Ebine N, Tsushima E, Oka E, Kumeta K, Tsukamoto T, et al. Seaweed favorably alters estrogen and phytoestrogen metabolism and these changes likely include modulation of colonic bacteria. Application of an improved ELISA assay to the analysis of urinary estrogen metabolites, Estrogen hydroxylation: the good and the bad, LC/PDA/MS analysis of dietary phytoestrogens from human urine and blood. Stir until all the ingredients come together. Based on changes in urinary iodine during the seaweed supplementation periods, adherence to the study protocol was very high. It is highly nutritious. Alaria esculenta (L.) Greville grows along the northeastern shores of North America. No—glutamate or glutamic acid have nothing to do with gluten. Overall breast cancer incidence rates for resident Japanese-Americans are somewhat lower (103/100,000) (2) than the national U.S. average (118/100,000) (3). 1). Mushroom Inonotus sanghuang alleviates experimental pulmonary fibrosis: Implications for therapy of pulmonary fibrosis. This type of seaweed is called Nori in Japanese. Maltrin M100 maltodextrin (Grain Processing) was used as placebo and 5 g/d provided 75.6 kJ. Nutritional epidemiologic studies in Japan rarely include seaweed, partly because it is hard to quantify, being consumed in both dried and rehydrated forms, includes a variety of different types of seaweeds, and because a hot water seaweed extract (Japanese dashi) broth is used to flavor many dishes so that the presence of seaweed is not obvious. In Asian cultures, seaweed is commonly cooked with foods containing goitrogens such as broccoli, cabbage, bok choi and soy. Researchers have only just begun to uncover the medicinal properties of the unique chemical compounds found in seaweeds. Seaweed fiber reaching the colon may be prebiotic, providing substrate for specific bacteria associated with increased equol production (33). Linear contrasts were used to test for the main effects and the interaction effects. A small but significant decrease in E1 was noted during the SeaSoy period. All capsules were taken with the last meal of the day. Very sadly out. Unless you’re a sushi lover, seaweed is probably not something you eat every day (or even think of as a tasty treat!). When most people think of seaweed, they think of long tangled leafy tendrils floating in the ocean or laying ashore crisscrossing sandy beaches. The Alaria was collected in June from the Sally Islands by Maine Seaweed Company following standard collection protocols (22). In Asia sea vegetables can make up 10 to 15% of the diet. Because this was a pilot study to determine whether a 5-g/d dose of seaweed would have any measurable effect on estrogen and phytoestrogen metabolism, changes in colonic microflora were not measured directly. When they were browned, he poured in water and a generous splash of dark soy sauce. Skibola (16) reported seaweed supplementation lowered serum E2 in 3 U.S. premenopausal women with menstrual dysfunction. Breast cancer incidence rates for Japanese women who migrate to the US rise dramatically after 10 y, increasing from 20/100,000 to 35/100,000 (1). To rule out potential concerns about incomplete urine collections, analyses were conducted with both amount per day and amount per unit of creatinine, a metabolite that is excreted in fairly constant amounts day to day. A soy protein ingredient made with soy protein isolate [High Protein Nutritious Food Ingredient Powder (AB1.2 HG 20CA 29)] was provided by Solae, LLC (formerly Protein Technologies). Seaweed and soy foods are consumed daily in Japan, where breast cancer rates for postmenopausal women are significantly lower than in the West. To assess the potential for weight to modify the effect of seaweed, an exploratory correlation analysis was conducted using a seaweed dose variable (mg/kg). In these models, subject was fit as the repeated factor whereas treatment group (4 levels: placebo, seaweed, soy, and SeaSoy), sequence of treatment administration, disease status, disease status × treatment interaction, and age were fit as independent variables. However, many cultures have regularly consumed seaweed for centuries to their great benefit.Let’s look at some of … Search for other works by this author on: Cancers of the prostate and breast among Japanese and white immigrants in Los Angeles County, Cancer incidence, mortality, and associated risk factors among Asian Americans of Chinese, Filipino, Vietnamese, Korean, and Japanese ethnicities, Department of Health and Human Services US. At the end of the study, an additional 15 women were excluded from analyses for these reasons: tamoxifen use (4), antibiotic use during the study (4), resumption of menses (1), failure to take the supplements (1), and inability to follow protocol (consumed >2 drinks/wk) (5). And, because I wanted to create a flavorful and accessible seaweed salad recipe that was also Autoimmune Protocol -friendly, that put these two ubiquitous ingredients out of reach. The interactive effect of soy and seaweed on colonic microflora merits further study. The lower limit of detection for this kit was 1.8 pmol/L. Does seaweed have b12? Fourteen of the participants had significant increases (mean = 2.2 ± 1.4 μmol/d; P = 0.0001) during the seaweed period; all 15 women had increases during the SeaSoy supplementation period (2.0 ± 1.0 μmol/d; P = 0.0001). U.S. Cancer Statistics Working Group. Brown seaweeds have unique insoluble indigestible fiber that has been shown to directly affect intestinal microflora (13,14). 3 strikes, and it's out. It is unclear if there might be physiologic benefits associated with increased equol levels for equol producers, although SeaSoy for these women was associated more favorable urinary estrogen metabolite profiles. Samples were collected a total of 6 times (blood samples and 48-h urine collection) throughout the study. Seaweed is a rich source of iron and iodine. Treatment arms were either 7 wk of 5 g/d seaweed powder (10 capsules) or 7 wk of 5 g/d maltodextrose in 10 identical gelatin capsules, followed by a 3-wk washout period and then crossed over to the opposite treatment arm.
