black tea1cancer preventioncancerplant extract117471665Highly conflicting evidence on cancer (some studies suggest benefits, others report no effects). Black tea does contain antioxidants but green tea has more - and besides the 'take antioxidants' to improve your health theory has largely been disproved. Why not make yourself a nice cup of tea while you think about this?Several studies have explored a possible association between regular consumption of black tea and rates of cancer in populations. This research has yielded conflicting results, with some studies suggesting benefits, and others reporting no effects. Laboratory and animal studies report that components of tea, such as polyphenols, have antioxidant properties and effects against tumors. However, effects in humans remain unclear, and these components may be more common in green tea rather than in black tea. Some animal and laboratory research suggests that components of black tea may be carcinogenic, although effects in humans are not clear. Overall, the relationship of black tea consumption and human cancer remains undetermined.

camu camumyrciaria dubia, camucamu, cacari, camocamo1oxidative stressgeneral health, cancerfruitOTW1,304127Very high in vitamin C. But a single study of smokers suggests its powerful anti-oxidant and anti-inflammatory effects may be due to other substances in the fruit.2008: 70ml of camu-camu juice per day, containing 1050mg vitamin C, or just 1050mg vitamin C (control) given to 20 male smokers for 7 days. Oxidative stress and inflammatory markers decreased significantly in the camu-camu group, while there was no change in the vitamin C group. Camu-camu juice may have powerful anti-oxidative and anti-inflammatory properties, compared to vitamin C tablets containing equivalent vitamin C content. These effects may be due to the existence of unknown anti-oxidant substances besides vitamin C or unknown substances modulating in vivo vitamin C kinetics in camu-camu. et al 2008

cherries2general healthgeneral healthfruitOTW73961185Cherries are nutritionally rich. In lab and animal studies, show antioxidant and anti-cancer effects. But human studies are needed. Cherries, and in particular sweet cherries, are a nutritionally dense food rich in anthocyanins, quercetin, hydroxycinnamates, potassium, fiber, vitamin C, carotenoids, and melatonin. These constituent nutrients and bioactive food components support the potential preventive health benefits of cherry intake in relation to cancer, cardiovascular disease, diabetes, inflammatory diseases, and Alzheimer's disease. Mechanistically, cherries exhibit relatively high antioxidant activity, low glycemic response, COX 1 and 2 enzyme inhibition, and other anti-carcinogenic effects in vitro and in animal experiments. Well-designed cherry feeding studies are needed to further substantiate any health benefits in humans. et al 2011

No evidence for weight loss.Two 2012 studies: consumption of milled chia seeds increased levels of two types of omega 3 - ALA and EPA - in postmenopausal women but had no effect on DHA levels, inflammation or other disease risk factors. 2009: 50 g chia seeds per day for 12 weeks raised ALA levels but had no effect on body composition, inflammation, oxidative stress, blood pressure, and lipoproteins among overweight and obese people of both sexes. 2009 review: There is limited evidence supporting the efficacy of Salvia hispanica for any indication; thus far, only two clinical studies have examined the effects of Salvia hispanica on cardiovascular disease (CVD) risk factors (including body weight). One study showed some effects on some CVD risk factors, while the other did not. Neither study showed any effects of Salvia hispanica on weight loss. et al 2009
chlorellaChlorella pyrenoidosa1blood pressurecardioalgaOTW19722151Good source of magnesium and GABA (a chemical with a calming effect on the brain). Has slight lowering effect on blood pressure. More research needed.2009: 20mg of chlorella (a kind of algae) twice a day for 12 weeks significantly decreased systolic blood pressure in people compared with placebo, especially among those already with borderline hypertension. The authors suggest its high GABA levels are related to the BP reduction. Diastolic blood pressure also tended to decrease, but not significantly. 2010: 52 Korean male smokers took 6.3g of chlorella or placebo every day for 6 weeks. Antioxidant status improved. Blood pressure tended to decrease, but not significantly. et al 2009
chocolate, dark4blood pressurecardiograin / pulse6132151502-18 weeks of dark chocolate slightly (but significantly) reduces blood pressure in those with high blood-pressure. Less effect on those with normal blood pressure.Meta-analysis: significant blood pressure-reducing effect of cocoa-chocolate compared with control (mean BP change +/- SE: SBP: -3.2 +/- 1.9 mmHg, P = 0.001; DBP: -2.0 +/- 1.3 mmHg, P = 0.003). However, subgroup meta-analysis was significant only for the hypertensive or prehypertensive subgroups (SBP: -5.0 +/- 3.0 mmHg; P = 0.0009; DBP: -2.7 +/- 2.2 mm Hg, P = 0.01), while BP was not significantly reduced in the normotensive subgroups (SBP: -1.6 +/- 2.3 mmHg, P = 0.17; DBP: -1.3 +/- 1.6 mmHg, P = 0.12). CONCLUSION: dark chocolate is superior to placebo in reducing systolic hypertension or diastolic prehypertension.

chocolate, dark2cardiovascular disease, diabetescardio, diabetesgrain / pulseOTW61327150People who eat more chocolate have a lower risk of heart disease (by 37%), stroke (29%) and diabetes. But properly controlled trials needed. It could be something other than the chocolate.A 2011 review of 7 studies including 114,009 participants found 5 of the studies reported a beneficial association between higher levels of chocolate consumption and the risk of cardiometabolic disorders (cardiovascular disease, myocardial infarction, stroke, ischaemic heart disease, heart failure, diabetes, metabolic syndrome). The highest levels of chocolate consumption were associated with a 37% reduction in cardiovascular disease and a 29% reduction in stroke compared with the lowest levels. However, none of these studies was a randomised controlled trial. RCTs are needed to establish this link firmly. et al 2011

coffee2depressionmental health, womengrain / pulse352287721Women who drink more coffee (not decaf) have a lower depression risk. More research needed on whether caffeine prevents depression. A large study of over 50,000 US women followed for 10 years found depression risk decreases with increasing caffeinated coffee consumption. Compared to women drinking less than a cup a week, the risk of developing depression among women consuming 2-3 cups / day was 15% lower and for 4+ cups a day 20% lower. Decaffeinated coffee was not associated with depression risk. Further investigations are needed to confirm this finding and to determine whether usual caffeinated coffee consumption can contribute to depression prevention. et al 2011

But coffee raises cholesterol and worsens insomnia and some heart problems. Caffeine withdrawal an obvious downside for the addicted. Pregnant and postmenopausal women should avoid drinking too much. 2011 review: coffee consumption inversely correlated with incidence of diabetes mellitus, various cancer lines, Parkinsonism, and Alzheimer's disease. Coffee ameliorates oxidative stress and caffeine and its metabolites help in proper cognitive functionality. Coffee lipid fraction containing cafestol and kahweol act as a safeguard against some malignant cells by modulating the detoxifying enzymes. On the other hand, their higher levels raise serum cholesterol, posing a possible threat to coronary health, for example, myocardial and cerebral infarction (heart attacks and strokes), insomnia, and cardiovascular complications. Caffeine also affects adenosine receptors and its withdrawal is accompanied with muscle fatigue and allied problems in those addicted to coffee. An array of evidence showed that pregnant women or those with postmenopausal problems should avoid excessive consumption of coffee because of its interference with oral contraceptives or postmenopausal hormones. and Sultan 2011

cranberry productscranberry juice, cranberries1urinary tract infectionsurinary, womenplant extract473624166Cranberry juice doesn't prevent painful urinary tract infections. In trials many people stopped drinking it. Cranberry tablets and capsules also ineffective.In a 2012 review of 24 studies (4473 participants) comparing cranberry products with control or alternative treatments, there was a small trend towards fewer UTIs in people taking cranberry product compared to placebo or no treatment but this was not a significant finding. Many people in the studies stopped drinking the juice, suggesting it may not be a acceptable intervention. Cranberry juice does not appear to have a significant benefit in preventing UTIs and may be unacceptable to consume in the long term. Cranberry products (such as tablets or capsules) were also ineffective (although had the same effect as taking antibiotics), possibly due to lack of potency of the 'active ingredient'. The Cochrane review of cranberry products for the treatment of UTIs found no suitable studies. review: Cranberries for preventing urinary tract infections

Not clear whether omega 3 intake has any effect on heart attack, stroke or cancer risk, or risk of death from any cause. But potent at lowering triglycerides (which increase cardio disease risk) among people with high levels.2009 Cochrane review: it is not clear whether dietary or supplemental omega 3 fats (found in oily fish and some vegetable oils) alter total deaths, cardiovascular events (such as heart attacks and strokes) or cancers in the general population, or in people at risk of, or with, cardiovascular disease. When the analysis was limited to fish-based or plant-based, dietary or supplemental omega 3 fats there was still no evidence of reduction in deaths or cardiovascular events in any group. 2012 meta-analysis: insufficient evidence of a secondary preventive effect of omega-3 fatty acid supplements against overall cardiovascular events among patients with a history of cardiovascular disease. 2012 second meta-analysis: omega-3 PUFA supplementation was not associated with a lower risk of all-cause mortality, cardiac death, sudden death, myocardial infarction, or stroke based on relative and absolute measures of association. 2009 meta-analysis: Fish oil supplementation produces a clinically significant dose-dependent reduction of fasting blood TG but not total, HDL or LDL cholesterol in hyperlipidemic subjects. 2011: both EPA and DHA reduce triglycerides review: Omega 3 fatty acids for prevention and treatment of cardiovascular disease

Omega 3 increases weight and appetite, improves quality of life and health after surgery. More than 1.5 grams per day for at least 8 weeks recommended.A 2007 systematic review of 17 studies (8 of high quality) found oral supplements with n-3 fatty acids benefit patients with advanced cancer and weight loss. The advantages observed were: increased weight and appetite, improved quality of life, and reduced post-surgical morbidity.

fish oil / omega 31asthmageneral healthanimal product463791015Changing your diet to include more fish oil does not improve asthma.Eating more fish has been recommended as one way of possibly reducing asthma. Populations (such as Eskimo communities) with diets high in fish also have low rates of asthma. As diets in other communities have become higher in saturated fats, asthma has also increased. The theory has been that an ingredient in fish oil may reduce inflammation. Inflammation causes the swelling in the airways of the lungs that leads to asthma attacks. However, this review of trials found that people with asthma changing their diets to include more fish oil did not improve their asthma. review: Dietary marine fatty acids (fish oil) for asthma in adults and children
fish oil / omega 32cognitive function in young peoplemental healthanimal product463781015DHA (a kind of omega 3 fatty acid) may or may not improve aspects of cognitive function among children.2013 review: McNamara et al. (2010) showed in healthy boys (8–10 years old) that only 8 weeks of supplementation with 400 mg (low, normal dose) or 1200 mg (high dose) of DHA per day dose improved reaction time during performance on an attention task. Not all positive effects have been found. In Kennedy et al. (2009), 90 healthy, cognitive intact 10–12 year old children were fed either 400 mg or 1000 mg of DHA per day for 8 weeks, but reported no reliable beneficial effects of these diets on cognitive performance. Karr et al. (2012) assessed the effects of a four week fish oil (480 mg DHA/720 mg EPA) treatment in healthy college-aged individuals on cognitive performance, but reported limited cognitive benefits, although acknowledged that the dose of fish oil may have been sub-therapeutic and sample size too small. and Song 2013

fruit + veg, all types3cancer preventioncancerfruit30790121369Contrary to popular belief, eating fruit and vegetables has little effect on overall cancer risk. But specific groups of vegetables may protect against particular cancer types. Contrary to popular belief, evidence suggests eating fruit and vegetables has little effect on overall cancer risk. 2011 review: 'The possibility that fruit and vegetables may help to reduce the risk of cancer has been studied for over 30 years, but no protective effects have been firmly established..' An analysis (Boffetta et al, 2010) involving 142 605 men and 335 873 women over 1992-2000 found that high fruit and vegetable intake lowers cancer risk only by a small amount: around 1-3%. The study found a stronger reduction in risk in heavy drinkers, confined to cancers caused by smoking and alcohol. However, consumption of specific groups of vegetables and fruits may protect against subtypes of esophageal and gastric cancer. For example, the risk of developing a type of oesophageal cancer dropped by 19% per 25g/day of raw vegetables consumed, and brassica vegetable consumption was associated with lowered risk of a type of stomach cancer. et al 2010

garlic 2cancer preventioncancervegetable1395022247Eating more garlic is associated with lower cancer risk, especially for stomach and intestinal cancers. However, the link may or may not be causal. More research needed.Preliminary studies suggest that garlic consumption may reduce the risk of developing several types of cancer, especially cancers of the gastrointestinal tract. Several population studies show an association between increased intake of garlic and reduced risk of certain cancers, including cancers of the stomach, colon, esophagus, pancreas, and breast. Most of the studies evaluated different types of garlic preparations and used them in varying amounts. If garlic consumption does reduce the risk of developing cancer, the amount needed to lower risk remains unknown. Cancer Institute

goji berry wolfberry1eye healthgeneral healthfruitOTW2047225High in antioxidants needed for good vision. Goji supplements for 90 days increase blood levels of these antioxidants and improves some measures of eye health. More trials needed.2011: Goji berry (Lycium barbarum L.) is purported to benefit vision because of its high antioxidant (especially zeaxanthin) content, although this effect has not been demonstrated in high-quality human studies. Daily dietary supplementation with goji berry for 90 days increases plasma zeaxanthin and antioxidant levels as well as protects from hypopigmentation and soft drusen accumulation in the macula of elderly subjects. However, the mechanism of action is unclear, given the lack of relationship between change in plasma zeaxanthin and change in macular characteristics. 2005: Epidemiological studies provide some evidence that an increased consumption of lutein and zeaxanthin with the diet is associated with a lowered risk for age-related macular degeneration, a disease with increasing incidence in the elderly. 2005b: 2005: Zeaxanthin in whole wolfberries is bioavailable and that intake of a modest daily amount markedly increases fasting plasma zeaxanthin levels. et al 2011

green coffee beans3high blood pressurecardiograin / pulseOTW2,709432Green (unroasted) coffee appears to lower blood pressure while ordinary roasted coffee does not. The more green coffee is drunk, the larger the effect. Why? The BP-lowering effects of beneficial acids in green coffee seem to be inhibited by other compounds produced during the roasting process.2005: blood pressure among 117 male volunteers with mild hypertension was significantly reduced over 28 days in a dose-related manner by daily green coffee bean extract. 2006: 140 mg / day chlorogenic acids from green coffee beans reduced blood pressure among 28 men with mild hypertension. 2008: hydroxyhydroquinone (HHQ), produced by roasting green coffee beans, may inhibit the antihypertensive effect of chlorogenic acids in brewed coffee. But this study showed reducing HHQ had no effect on blood pressure. 2008: reduced HHQ coffee did lower blood pressure in a dose-dependent manner compared to ordinary coffee. et al 2008

hawthorncrataegus spp.5chronic heart failurecardiofruit275510104Hawthorn extract made from dried hawthorn improved heart function and symptoms of heart failure in patients with chronic heart failure. Appears beneficial when used in on top of existing treatment.2009 Cochrane review: Hawthorn extract (made from the dried leaves, flowers and fruits of the hawthorn bush) may be used as an oral treatment option for chronic heart failure. In this review, 14 double-blind, placebo controlled randomised clinical trials (RCTs) were found. They did not all measure the same outcomes and several did not explain what other heart failure treatments patients were receiving. Those trials (10 trials, 855 patients) that could be included in a meta-analysis showed improvements in heart failure symptoms and in the function of the heart. The results, therefore, are suggestive of a benefit from hawthorn extract used in addition to conventional treatments for chronic heart failure. review: Hawthorn extract for treating chronic heart failure
