For the last few years, many people have been making claims about organic food being superior. That very same evening, I found myself in what must be one of the most upscale supermarkets on the planet—the flagship Whole Foods in the company's (and my) hometown of Austin. And while Whole Foods' offerings didn't look much different from normal supermarket tomatoes, their price tag did capture my attention.
My overall verdict: These tomatoes were lackluster, little different than the ones that end up on the worst fast-food sandwiches. And if these unimpressive fruits are indeed imposing a harsh ecological toll on the region where they're grown, than that, to me, is a travesty. Vermont is poised to become the first state to require labels on genetically modified food, but will these "frankenfruits" actually hurt the people who eat them? Swapping genes in and out in a lab may sound a little different than cross breeding crops for hundreds of years, but according to Lisa Cimperman, a clinical dietician at University Hospitals in Cleveland, therea€™s no evidence that people are harmed by eating a bug-proof ear of corn or a non-browning apple. Read about how the FDA determined that genetically engineered salmon wona€™t hurt the environment. Petitions have shown up on Change.org asking for companies to get rid of GMOs a€“- or genetically modified organisms -- in foods from apples to Girl Scout Cookies, often citing safety concerns. Cimperman said the only immediate concern that people with food allergies may accidentally eat a a€?safea€? food without realizing one of its ingredients has been spliced with the genes of an allergen. For instance, in the 1990s, an engineered soybean made people with Brazil nut allergies have allergic reactions because they didna€™t realize the beana€™s genetic material included a gene from the Brazil nut, she said. For Cimperman, the biggest concern is whether human tampering will have an environmental effect, strengthening weeds and insects that evolve to beat the genetic engineering. When genetically engineered salmon was deemed safe for the environment in late 2012, former Rep. He introduced federal legislation related to genetically modified food and labeling in every Congress since 1997, but it has never passed.

Table 4.Total acidity (TA) and total soluble solid (TSS) content of three tomato cultivars from organic and conventional production systemAt the same time, it should be noted that Elpida tomatoes were richer in organic acids in comparison to other examined cultivars, independently from the used cultivation system (Table 4).

April McCarthy, Prevent Disease?The tomato was one of the first commercially available genetically modified (GM) crops. Today, tomatoes are being genetically modified to produce a peptide that mimics the actions of HDL cholesterol that biotechnology groups are promoting to supposedly reduce heart disease.
Led by Dr Alan Fogelman from the University of California, Los Angeles (UCLA), USA, his study found that consumption of GM tomatoes resulted in reductions of plaque build-up in arteries (atherosclerosis). The rollout into major grocery retailers is expected, however no timeline has been established until more research is completed.
Fogelman and his team fed the tomatoes to mice that lack the ability to remove low density lipoprotein (LDL) or cholesterol from their blood, and therefore develop inflammation and atherosclerosis when consuming a high-fat diet. There are many other biotech projects aiming to enrich tomatoes with substances that may offer health benefits which claim to be more nutritious, however no human or long-term studies are planned to discover their effects on metabolism. Monsanto developed tomatoes that delayed ripening by preventing the production of ethylene, a hormone that triggers ripening of fruit. Tomatoes (along with potatoes, bananas and other plants) are also being investigated as vehicles for delivering edible vaccines. Although GM foods can only be planted in many countries as part of a trial, and even then only under strict conditions, millions of hectares of the crops have already been planted in the Americas. Campaigners have warned that there is no compulsory labelling of meat or dairy products from animals which have been fed on GM crops, and that any long-term problems from eating the foods is still unknown. I have just recently moved back to the states from Shanghai, China and have actually been trying to eat more organic food because rumor has it - it is better for you.
She, too, is a tomato lover—she introduced me to the pleasure ripe seasonal tomatoes some decades ago. Tom PhilpottFor me, a great tomato has a balance of acidity (foodie-speak for bright, tart flavor) and sweetness. I wouldn't buy them again for a dime a pound, much less for the heirloomesque prices they're fetching. Barry Estabrook, author of Tomatoland, read my post from yesterday and emailed me to urge me to look more closely at one supplier of Baja-grown organic winter tomatoes, US-owned Del Cabo Cooperative. Even Golden rice, a genetically modified crop developed to get extra vitamin A to people lacking it in their diets, has been protested. Once researchers confirmed the allergen was passed on in the genetic engineering process, the company halted production, she said.

Thus, Elpida’ tomato fruit in organic production system contained the highest level of vitamin C. For instance, the concentration of yellow flavonoids was 70% higher in organic fruits when compared to fruits from conventional growing system, but only at the harvesting stage, which is consistent with similar observations previously [57]. We don't shy away from controversy, and will publish anything that interests us and matches our focus for the site. This meant that the tomato plant was no longer able to produce polygalacturonase, an enzyme involved in fruit softening.
Although they were approved in the US and several other countries, tomatoes with delayed ripening have disappeared from the market after peaking in 1998. Although the tomatoes were briefly tested in the marketplace, patent arguments forced its withdrawal. Clinical trials have been conducted on mice using tomatoes that stimulate antibody production targeted to norovirus, hepatitis B, rabies, HIV and anthrax. I have not been in the states long enough to form my own opinion on the organic craze, but I am glad I stumbled on your blog post. Do you think it is still worth going organic to support the environment rather than going organic to better my health?
The scientists says this difference between organic and conventional tomatoes can be explained by the manure used to grown them.Let's All Stop Using the Phrase 'Conventional Agriculture'And another tangent, this time into language use. Our August-September tomato season is sacred to me, as are the jars of them we put up for the rest of the year.
Texture-wise, great tomatoes should yield easily to the tooth, giving off a burst of juice at the bite.
It offered a meager acidity, not balanced in the slightest by sweetness; the texture was too firm, and its juice thin and watery. Irrespective of the cultivation method used, ‘Elpida’ on average also contained the highest level of vitamin C (14.3 mg 100g-1) in comparison to the rest of the examined tomato cultivars.
The concentration in anthocyanins was lower in the fruits from organic farming at all three stages of fruit development [56].


The premise was that tomatoes could be left to ripen on the vine and still have a long shelf life, thus allowing them to develop their full flavour. Submit your article contributions and participate in the world's largest independent online news community today!
I was very interested in your findings that there is no true difference between organic foods and inorganic foods. If you're not already, let's together make a pact that we will never use the word 'conventional' to describe non-organic agriculture. Not unlike the non-organic winter tomatoes found in supermarkets throughout the land, their red hue looked sort of pale.
It also claims to encourage biodiversity, and not monocrops, on the farms it sources from. The conventionally grown Amati and Robin tomato fruits contained more vitamin C than their organically grown counterparts [38].5.
These discrepancies indicate that organic farming had the effect of modifying the levels of transcripts or the activities of enzymes controlling intermediary steps of the biosynthetic pathway of phenolic compounds. Your ending question about producing organic foods as a business rather than benefitting societies health made me think that maybe organic food aids society in a different way. If you have on one hand organic agriculture, and there's actually a legal definition of that specifying what is and isn't organic, then conventional is not the opposite of that. If I hadn't written about organic winter tomatoes from Mexico that very day, Whole Foods' mediocre-looking display would not have caught my eye at all.
Next up was the greenhouse tomato, whose faint acidity was nearly balanced by an even fainter sweetness; the texture was just ok. It may well be that small-scale, diversified growers use water less intensively than the large farms that are sucking Baja's water table dry.
Tomatoes are important not only because of the large amount consumed, but also because of their high health and nutritional contributions to humans.
In spite of the changes in antioxidants, the total antioxidant activity was not significantly different among the organic and conventional tomatoes (Table 2).6.
Conventional doesn't actually describe the agricultural practices themselves, except that today they are the norm. My mother liked this one; I thought it had made a valiant lunge for mediocrity, and almost achieved it. The tomato processing industry has made tremendous advances, developing many forms of tomato-based foods, such as sauces, catsup (ketchup), puree, pastes, soups, juices and juice blends, and canned tomatoes either whole or in diced, sliced, quartered or stewed form [2]. The typical color changes during tomato ripening from green to red are associated with chlorophyll breakdown and the synthesis of carotenoid pigments due to the transformation of chloroplasts to chromoplasts [39]. Mineral contentGrowing method and cultivar had significant influence on K, Ca, Na or Mg contents in tomato fruits. On the contrary, significantly greater concentrations of Zn in conventional tomatoes were found [58]. The third one, the beefsteak, was abysmal: unpleasantly acidic, no sweetness, and a harsh, almost salty flavor overwhelming everything. The tomato’s attractive color and flavor have made it a dietary staple in many parts of the world.
Pigment synthesis in tomato is closely related to the initiation and progress to ripening and red color of the fruit results from the accumulation of lycopene [40], so that lycopene has been suggested as a good indicator of the level of ripening. On the other hand, in the present study, one possible hypothesis that may explain the insignificant differences in the majority of the minerals could be that the tomato plants of the two cultivation methods managed to have similar soil conditions and irrigation.
No significant differences were found between the cultivars in the mean taste index obtained for conventionally cultivated tomatoes.
Lycopene is considered the predominant carotenoid of tomato fruit (80-90%), followed by ?-carotene (5-10%) [41].The lycopene level of tomato fruit is determined by the genetic potential of the cultivar. When using these data, the mean values of the taste index in all the tomatoes belonging to all the cultivars considered were higher than 0.85, which indicates that the tomato cultivars analyzed are tasty.
We found significantly greater concentrations of P, K, Ca and Mg in organic tomatoes, but in conventionally grown tomato we found greater content of Zn, Fe and Cu [60]. Significant differences in the concentration of Na, Ca, Mg and Zn in tomatoes grown in two different production regions of the island of Tenerife (Spain) have been reported [29].
Most importantly, tomato consumption has been shown to reduce the risks of cardiovascular disease and certain types of cancer, such as cancers of prostate, lung and stomach [9].
Some mineral contents in the tomato fruit must be influenced by the region of production, which is mainly influenced by the mineral contents of the cropping soils and of the water for irrigation [29].7. Acidity tends to decrease with the maturity of the fruits while the sugar content increases. The health promoting benefits of tomatoes and tomato products have been attributed mostly to the significant amount of lycopene contained. The skin of the tomato fruit contains high levels of lycopene, comprising an average of 37% of the total fruit lycopene content [45], or 3-to 6-fold higher than in whole tomato pulp [44]. Organically grown Elpida produced the highest level of potassium in fruit (164.31 mg100 g-1) comparing to the other two cultivars. The results of various studies suggest that lycopene plays a role in the prevention of different health issues, cardiovascular disorders, digestive tract tumors and in inhibiting prostate carcinoma cell proliferation in humans [10].As a potent antioxidant, lycopene is presently marketed as a fortified nutritional supplement [2]. About 12 mg of lycopene per 100 g fresh weight was found in tomato skin, while the whole tomato fruit contained only 3.4 mg 100g-1 fresh weight [47]. Conventional tomatoes contained more organic acids in comparison to those cultivated by organic methods, in all periods of analysis, being approximately about 0.48% [21].
The maturity index in this study (in all cultivars in both production systems) were higher than those found by maturity index reported by [64] was 9.4 and therefore, it can be deduced that the maturity levels of the analyzed tomatoes were adequate for consumption.
The outer pericarp constitutes the largest amount of total carotenoids and lycopene, while the locule contains a high proportion of carotene [46].The lycopene content of tomato fruit also varies due to growing and environmental conditions, mainly temperature and light. The carotenoid content of tomatoes is affected by cultural practices on one side – genotype and agronomic technique [11; 12] on the other side. The cultivar is a more influential factor than cultivation methods in the differentiation of the tomato samples according to the chemical characteristics.
Significantly greater concentrations of Ca and Mg in organic tomatoes also represented [58]. However, quality is more than this and can be defined as the sum of all characteristics that make a consumer satisfied with the product [65]. Fruits from the indeterminate tomato cultivar Daniela grown in the greenhouse had a higher lycopene content than field grown fruit [50]. Apart from functional and nutritional characteristics, quality can include aspects of production method, environment or ethics, as well as availability of and information about a product [66]. Organic tomatoes achieve higher prices and a guaranteed placement compared to conventional tomatoes [19], because these products are often linked to protecting the environment and to having better quality (taste, storage), and most people believe that they are healthier.
Lycopene content also changes significantly during maturation and accumulates mainly in the deep red stage [51].Tomatoes grown organically contained substantial amounts of lycopene when ripened to firm red or soft red stages. For all nutrients examined, cultivar differences were greater than differences because of cultivation method.
About half of the total lycopene found in soft red tomatoes was present in pink tomatoes and 70 percent in light-red fruit.


We observed no significant influence of growing method, which in the case of iron is in keeping with earlier findings [62].
This study confirms that the most important variable in the micronutrient content of tomatoes is the cultivar; organically grown tomato is no more nutritious than conventionally grown tomato when soil fertility is well managed [59]. Fruit picked at unripe stages (breaker through light red) gained as much or more lycopene as those picked at the firm or soft red stages. Greenhouse tomato production offers advantages compared to production at the open field with regard to quality assurance principally, because the plants are not exposed directly to the rapid changes of climate conditions.
Research results on the effects of organic and conventional production on fruit quality are sometimes contradictory.
An important role for this purpose is also the cultivar selection by using tomato hybrid varieties with a high yield potential and a good fruit quality.8. In terms of quality, some studies report better taste, higher vitamin C contents and higher levels of other quality related compounds for organically grown products [20; 23], whereas several other studies have found the opposite or no differences in quality characteristics between organically and conventionally grown vegetables [23]. Sensory attributesDuring tomato fruit ripening, a series of quantitative and qualitative changes take place, changing tomato flavor and aroma volatile profiles [67; 68]. The factors influencing tomato quality are complex and interrelated, and additional studies are necessary to consolidate the knowledge about the real interdependences.One major problem in comparative studies might be that genuine organic and conventional production systems differ in many factors and that a simple measurement of food composition does not reflect its quality. Regarding aroma, several descriptors are present in tomatoes and volatiles are part of the tomato aroma profile. Other scientists have argued that a valid comparison of nutritional quality would, for example, require that the same cultivars are grown at the same location, in the same soil and with the same amounts of nutrients [24; 25]. However, there is little information on the effect of different forms of cultivation on the antioxidant potential of tomatoes.3.
Hexanal is one of the major aldehydes in tomatoes and is considered important for fresh tomato flavour.Panelists could perceive a difference between conventional and organic tomatoes by smell or taste with high reliability.
Organic tomatoes were perceived by some of the panelist to be softer, and were preferred because of their taste, flavor, texture and juiciness.
The cultivar ‘Amati’ contained the lowest level of carotenoids in fruit in both cultivation systems. Alternatively, conventional tomatoes were described as 'not as ripe', 'dry', and having 'less aroma' [19].Very different patterns of correlation between nonvolatile and volatile components emerged as perceived by panelists, depending on whether the nasal passage was blocked to evaluate taste descriptors. The main variations concerned pest control, fertilization and fertility of soil, which was of much better quality in the organic production. A composite of all data collected over the three seasons revealed the ‘sweet’ note is positively correlated with soluble solids, total sugars, and sucrose equivalents with partitioning (taste followed by aroma).In previous studies, strong positive correlation has been observed between trained panel response of ‘sweetness’ and reducing sugar and total soluble solids content [70]. In conventional cultivation mineral fertilizers and chemical plant protection were applied.
Organically grown ‘Robin’ produced the highest level of carotenoids in fruit (4.03 mg 100g-1) comparing to the other two cultivars (Fig. Both 'tomato-like’ and ‘fruity’ were positively correlated to acidity and negatively correlated to soluble solids in aroma plus taste trials, but not in the taste followed by aroma trials.
2).Studies on carotene and lycopene contents in organic tomatoes, have reported different results including both higher levels [52] and lower levels [53] when compared with conventional methods. A possible explanation in the lack of correlations with many of these descriptors is that there was little difference between these treatments in the lines selected.
It is clear that evaluating for taste plus aroma was more sensitive than evaluating for aroma plus taste. For sensory evaluation fruits were evaluated by trained descriptive panelists on the day of harvest (red stage). It would however be impulsive to conclude that either production system is superior to the other with respect to healthy or nutritional composition [71].The fruit quality, in terms of taste and nutritional value, did not differ significantly between tomatoes grown in organic or conventional systems. Tomato samples (20 fruits) were collected each year from June till August and were taken from the third to sixth floral branches.Determination of total soluble solids (TSS) was carried out by a refractometer. The more stress plants suffer, the more polyphenols they produce,' these authors point out [55].
Tomato fruits from organic farming experienced stressing conditions that resulted in oxidative stress and the accumulation of higher concentrations of soluble solids as sugars and other compounds contributing to fruit nutritional quality such as vitamin C and phenolic compounds [56].Flavonoid content in tomatoes seems to be related to available N [34].
If the aim of organic systems is to produce fruit of superior quality, it is suggested that old cultivars could be used to develop new tomato cultivars adapted for organic cultivation rather than for conventional systems.9. Heavy metalsSome heavy metals at low doses are essential micronutrients for plants, but in higher doses they may cause metabolic disorders and growth inhibition for most of the plants species [73]. Each ashed sample was dissolved in 20 mL of 3 M HCl, and K, Ca, Na, Mg, Fe, Zn, Mn and Cu levels were determined by atomic absorption spectrophotometry.Besides, a taste index and the maturity were calculated using the equation proposed by X et al. If differences in flavonoid content reflect fundamental differences in the behavior of soil N between conventional and organic systems, then the N available to tomatoes late in the season may have declined in organic plots in recent years in response to the cumulative effects of a decrease in compost application rates [57]. Among the contaminants found in vegetables, heavy metals may reach different levels depending on their content in the soil and the type of fertilization used [73]. For this reason the type of farming techniques can affect the heavy metal content of tomatoes. PhytochemicalsThe levels of some phenolic compounds are known to be higher in organic fruit. Plants create phenolic compounds for many reasons, but a major reason is to make plant tissues less attractive to herbivores, insects and other predators. Producers of organic vegetables, do not use mineral fertilizers and practically never use fertilizers produced by industrial waste, which are the most polluted. Accordingly, it is important to sort out if higher levels of phenolic compounds affect the taste of organic fruits and vegetables when compared to conventionally grown produce [30].The organic growing system affects tomato quality parameters such as nutritional value and phenolic compound content. As a result, one might expect that organic vegetables contain lower amounts of toxic heavy metals. The effect of variety, season, harvest time, maturity, as well as environmental factors such as light, water and nutrient supply on the antioxidant content of tomatoes are reviewed by Dumas et al.
Farm management skills combined with site-specific effects contribute to high vitamin C levels, and the choice of variety significantly influences the content of ascorbic acid [32].
Therefore, it is important to compare organic and conventional foods that are planted and harvested during the same season of the year and that originate from regions with similar incidence of solar radiation.Ascorbic acid content in organically fertilized tomatoes ranges between 29% and 31% [23, 34], which is higher than the results obtained from tomatoes that were fertilized with mineral solutions. The lower zinc content of the hybrids in organic farming compared to conventional production was not statistically significant. Similarly, ascorbic acid content in tomatoes cultivated with an organic substrate was higher than hydroponically cultivated tomatoes [35]. Many citations from literature confirm that tomatoes coming from organic cultivation procedures present higher vitamin C content than fruits from conventional cultivation [36; 37]. It was also found that fertilizer that was rich in soluble nitrogen (N) could cause a decrease in the ascorbic acid content, probably for indirect reasons, since the nitrogen supply increased the plants’ leaf density, which promoted shading over the fruits.
