The regulation of anthocyanin biosynthesis has been an area of significant interest. Genes involved in the anthocyanin biosynthesis pathway are regulated by ternary MYB-bHLH-WD40 complexes formed by R2R3-MYB transcription factors, bHLH transcription factors, and WD40 proteins . Jiang et al. revealed their cooperation to modulate anthocyanin production in the wheat purple pericarp. They reported that TFs, MYB 1, and bHLH co-regulate anthocyanin biosynthesis in purple pericarps of wheat.

Thus, the final anthocyanin content in the seed depends on the genotype and environment interaction. The invention of industrialized roller mills in the late 19th century changed the way we process grains. Milling strips away the oceanfront music bran and germ and leaves only the soft, easy-to-digest endosperm. Without the fibrous bran, the grain is easier to chew. The germ is removed because of its fat content, which can limit the shelf life of processed wheat products.

Wheat is filled with a host of nutrients that are great for your health. It contains catalytic elements, Vitamin E, Vitamin B, mineral salts, copper, calcium, iodide, magnesium, zinc, potassium, manganese, Sulphur, silicon, chlorine, and arsenic, which is why it is a great foundation for any diet. Guide to Non-Wheat Flours Wheat isn’t the only source of flour.

Ferulic and p‐coumaric acids have also been reported to have antiproliferative effects on human Caco‐2 colon cancer cells, but this effect has not been confirmed in vivo. The other important trait is adaptability to the environment. Morgounov et al. reported a more significant environmental effect than the genotype for purple wheat productivity.

In adults, allergy is most often reported among those regularly exposed to airborne wheat dust. If you have this condition, it may be best to limit wheat consumption. It is more common in people who experience anxiety and is often triggered by a stressful life event . In fact, approximately 30% of people with IBS experience a wheat sensitivity . Evidence suggests that wheat sensitivity is caused by fructans, which belong to a class of fibers known as FODMAPs . Frequently reported symptoms of wheat sensitivity include abdominal pain, headache, fatigue, diarrhea, joint pain, bloating, and eczema .

Similarly, black wheat cultivated at 24/17 °C in Tainan, China, has higher anthocyanin content than 35/18°C in India . Although, the anthocyanin content for blue wheat is not much different in the case of 22/15°C at Taian, China, 20/9°C at Kromeriz, Czech Republic, or 35/18°C for Mohali, India . Thus, genotype also has a significant influence on the anthocyanin content. Three genotypes of purple wheat from Denmark and two from Canada showed considerable differences in the anthocyanin content .

Further, native blue-colored wheat varieties are winter wheat in nature. It needs a prolonged vegetative phase for biomass production, but when transferred to the subtropical region, they experience multiple stresses because of poor adaptability. Garg et al. demonstrated that color wheat varieties adapted to various environments by using breeding strategies like crossing exotic winter color wheat lines to locally adapted spring wheat cultivars. They have generated colored wheat lines for the Indian environment having high anthocyanin content and a better yield . In another study, two different isogenic lines for purple grain in the background of cv.

Functional studies were performed in small mesenteric arteries in isometric myograph. Immunoblotting and fluorescence studies were made in arterial homogenates and arterial sections, respectively. These data agrees with the beneficial actions of RBEE on dyslipidemia, hyperinsulinemia and hypertension in obesity.

There was also variation in the percentage of stanols, by 2.6‐fold (from 11 to 29% total sterols). Lignin is a complex polymer of aromatic alcohols and is characteristic of the secondary cell walls of woody tissues. In wheat and other cereals it is only present in the pericarp/seed coat and hence is enriched in the bran and absent from white flour . The detailed structure of cereal grain lignin has been described by Bunzel et al. . Wheat is often considered primarily as a source of energy and it is certainly important in this respect.

The UK Scientific Advisory Committee on Nutrition has recently reviewed the evidence for health benefits of cereal fiber, as part of a wider review of dietary carbohydrates. Table8 therefore summarize its conclusions on the health benefits of wheat fiber, including data for “total fiber”, “soluble fiber” and “insoluble fiber” fractions which include fiber from other sources . These tables also include data for widely studied β‐glucan fractions from oats and barley. However, it should be noted that oat and barley β‐glucans differ from wheat β‐glucan in their structures and properties, being much more soluble and giving more highly viscous solutions (Li et al. 2006; Lazaridou and Biliaderis 2007). Table7 summarizes analyses of total dietary fiber and the major components (AX and β‐glucan) in wholemeal and white flour, with the AX being determined as total, water‐extractable (i.e., soluble) and water‐unextractable .
