Past studies have demonstrated that tea intake is beneficial to human health, and the positive effects include mood improvement and cardiovascular disease prevention. In fact, results of a longitudinal study led by Asst Prof Feng which was published in 2017 showed that daily consumption of tea can reduce the risk of cognitive decline in older persons by 50 per cent.
Following this discovery, Asst Prof Feng and his team further explored the direct effect of tea on brain networks.
The research team recruited 36 adults aged 60 and above, and gathered data about their health, lifestyle, and psychological well-being. The elderly participants also had to undergo neuropsychological tests and magnetic resonance imaging (MRI). The study was carried out from 2015 to 2018.
Upon analysing the participants’ cognitive performance and imaging results, the research team found that individuals who consumed either green tea, oolong tea, or black tea at least four times a week for about 25 years had brain regions that were interconnected in a more efficient way.
“Take the analogy of road traffic as an example, consider brain regions as destinations, while the connections between brain regions are roads. When a road system is better organised, the movement of vehicles and passengers is more efficient and uses less resources. Similarly, when the connections between brain regions are more structured, information processing can be performed more efficiently,” explained Asst Prof Feng.
He added, “We have shown in our previous studies that tea drinkers had better cognitive function as compared to non-tea drinkers. Our current results relating to brain network indirectly support our previous findings by showing that the positive effects of regular tea drinking are the result of improved brain organisation brought about by preventing disruption to interregional connections.”
Drinking tea at least three times a week is linked with a longer and healthier life, according to a study published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).
“Habitual tea consumption is associated with lower risks of cardiovascular disease and all-cause death,” said first author Dr Xinyan Wang, Chinese Academy of Medical Sciences, Beijing, China. “The favourable health effects are the most robust for green tea and for long-term habitual tea drinkers.”
The analysis included 100,902 participants of the China-PAR project2 with no history of heart attack, stroke, or cancer. Participants were classified into two groups: habitual tea drinkers (three or more times a week) and never or non-habitual tea drinkers (less than three times a week) and followed-up for a median of 7.3 years.
Habitual tea consumption was associated with more healthy years of life and longer life expectancy.
For example, the analyses estimated that 50-year-old habitual tea drinkers would develop coronary heart disease and stroke 1.41 years later and live 1.26 years longer than those who never or seldom drank tea.
Compared with never or non-habitual tea drinkers, habitual tea consumers had a 20 percent lower risk of incident heart disease and stroke, 22 percent lower risk of fatal heart disease and stroke, and 15 percent decreased risk of all-cause death.
The potential influence of changes in tea drinking behaviour were analysed in a subset of 14,081 participants with assessments at two time points. The average duration between the two surveys was 8.2 years, and the median follow-up after the second survey was 5.3 years.
Habitual tea drinkers who maintained their habit in both surveys had a 39% lower risk of incident heart disease and stroke, 56% lower risk of fatal heart disease and stroke, and 29% decreased risk of all-cause death compared to consistent never or non-habitual tea drinkers.
Senior author Dr. Dongfeng Gu, Chinese Academy of Medical Sciences, said: “The protective effects of tea were most pronounced among the consistent habitual tea drinking group. Mechanism studies have suggested that the main bioactive compounds in tea, namely polyphenols, are not stored in the body long-term. Thus, frequent tea intake over an extended period may be necessary for the cardioprotective effect.”
In a subanalysis by type of tea, drinking green tea was linked with approximately 25% lower risks for incident heart disease and stroke, fatal heart disease and stroke, and all-cause death. However, no significant associations were observed for black tea.
Dr. Gu noted that a preference for green tea is unique to East Asia. “In our study population, 49% of habitual tea drinkers consumed green tea most frequently, while only 8% preferred black tea. The small proportion of habitual black tea drinkers might make it more difficult to observe robust associations, but our findings hint at a differential effect between tea types.”
Two factors may be at play. First, green tea is a rich source of polyphenols which protect against cardiovascular disease and its risk factors including high blood pressure and dyslipidaemia. Black tea is fully fermented and during this process polyphenols are oxidised into pigments and may lose their antioxidant effects. Second, black tea is often served with milk, which previous research has shown may counteract the favourable health effects of tea on vascular function.
Gender-specific analyses showed that the protective effects of habitual tea consumption were pronounced and robust across different outcomes for men, but only modest for women. Dr. Wang said: “One reason might be that 48% of men were habitual tea consumers compared to just 20% of women. Secondly, women had much lower incidence of, and mortality from, heart disease and stroke. These differences made it more likely to find statistically significant results among men.”
She added: “The China-PAR project is ongoing, and with more person-years of follow-up among women the associations may become more pronounced.”
The authors concluded that randomised trials are warranted to confirm the findings and provide evidence for dietary guidelines and lifestyle recommendations.
Breast Feeding Week: RSUTH Targets Health Personnel
As part of measures to heighten the importance of breast feeding, authorities in the State owned Rivers State University Teaching Hospital (RSUTH) is set to sensitise its personnel on the need to ensure that nursing mothers embrace exclusive breast feeding.
The programme forms part of the weeklong activity on breast feeding and is billed to hold tomorrow to school staffers on the health benefits and why they should support the campaign
Member of a committee set up on breast feeding, Nurse Agana Ebirien in a chat with The Tide said the hospital is breast feeding friendly and has over the years held campaigns within and outside the hospital to promote breast feeding.
She stressed the need for health workers to be ambassadors at the forefront for the quest to ensure breast feeding is highly embraced by mothers visiting the health facility.
Ebirien said this year’s theme: “Step Up Breast Feeding, Educate and Support” is aimed at raising awareness and underscoring the need for nursing mothers to exclusively breast feed their babies.
She said, “Most nursing mothers don’t want to breast feed their babies because of the myths surrounding breast feeding. Some of the myths include danger of colostrum and many others.”
Ebiriien explained that the colostrums which is the first drop of breast milk from a nursing is the richest and healthiest part of the breast milk, as it helps boost the baby’s immunity and prevents him from falling ill frequently.
The nursing expert therefore called on nursing mothers to ensure they breast feed their babies exclusively for at least six months, and then breast feed with complementary feeding upto two years.
A nurse and expert on women health, Nurse Agana Ebirien has listed the benefit of breast feeding with the call on nursing mothers to exclusively breast feed their babies for at least six months without water or glucose water.
Nurse Ebirien in an exclusive chat with The Tide said thre are huge benefits of exclusive breast feeding to help the mothers and baby health in the future
Some of the benefits she said include the boosting of the child’s immunity, and improving the child memory and intelligence.
She noted that mothers who breast feed their babies help curb obesity in their babies in the future, as she described breast milk as “ balanced diet in balanced proportion”.
For the mothers she noted that breast feeding help to heal the uterus , “ as the baby sucks the breast the uterus contract and that curbs bleeding in mothers.”
In addition, the nurse explained that mothers who breast feed their babies for a long time also reduce the occurrence of breast and ovarian cancers.
She added that breast feeding is calso economical as it saves the family from spending huge sums from buying milk and other condiments to feed the baby, and therefore called on fathers, and the menfolk in general to encourage their wives to breast feed their babies.

Tiger Nuts Can Heal Urinary Infections -Study
The experts have evaluated the antioxidant vitamins (vitamins A, C and E) and antibacterial potential of tiger nut extracts against germs that cause human urinary tract infection pathogens. These are Escherichia coli, Staphylococcus aureus and Klebsiella pneumonia.
Many individuals, including diabetics, eat tiger nut mainly for its sweetness and for its high content of arginine, which is reported to stimulate the production of insulin. Now, in a new study, researchers have said it is a fruit that should be consumed more to prevent and treat urinary tract infections.
The susceptibility of these disease-causing germs towards the tiger nut extracts was compared with each other and with gentamicin, which was used as a positive control. All plant extracts showed antimicrobial activities against the selected microorganisms at various concentrations and the methanol extract was found to be most effective compared to ethyl acetate extract.
In addition, the antioxidant vitamin composition in the different extracts of tiger nut indicated that it contained an appreciable amount of these vitamins. However, the concentrations of these vitamins were considerably higher in the methanol extract, with Vitamin E exceeding the daily recommended intake by international standards in both extracts.
The study published in the Journal of Agroalimentary Processes and Technologies involved Imaobong E. Daniel and Etukudo Edigeal D. at the Department of Chemistry, University of Uyo, Akwa Ibom State, and it was to authenticate the medicinal importance of tiger nut.
Urinary tract infections (UTI) affect any part of the urinary tract which could be the kidney, ureter, bladder and urethra. The causes of UTIs include sexual intercourse with infected persons, poor hygiene, holding urine longer than necessary, underlying kidney stones, diabetes and loss of oestrogen.
All over the world, millions of people are diagnosed with urinary tract infections (UTI) every year. It is estimated that about 35 percent of healthy individuals suffer from symptoms of UTI at some stage in their lives, with incidences occurring mostly in women than men.

Nursing Mothers Cautioned On Exclusive Breast Feeding
As Rivers State joins the rest of the world to observe the 2022 World Breast Feeding Week, some nursing mothers in Rivers State have cautioned their colleagues not to use poverty and hardship as an excuse against the practice of exclusive breastfeeding of their babies.
It would be recalled that some nursing mothers have cited poverty as factor responsible to practice exclusive breastfeeding of their babies.
Speaking, a mother of three from Okrika, Mrs Patience Owiriwa, said mothers have no excuse not to practice exclusive breastfeeding.
“I advise that as a mother, if you don’t have anything to feed a child, go for breast milk, even if it is little fish you buy to cook.
“That money you use for milk, use it to buy ‘Sungu’ and any good cooking things.
“If you buy N500 fish, you can cook soup that will carry you. When you are eating well, your baby is eating well too”, she said.
Owiriwa said exclusive breast milk prevents children from reacting to unnecessary sicknesses.
“He will be very OK. With breast milk, every vitamin is inside that breast milk; so, even if you feed him with only breast milk, he is good to go”.
Another respondent, Mrs Nnenna Amadi from Ikwerre Local Government Area said, “when you breast feed a child well, you find out that the baby will be OK.
“Moreover, when you do exclusive breastfeeding, the child will not be sick, he will be healthy and plump.
“The breast milk will make the child very sharp”, she said.
This year’s World Breastfeeding Week is from August 1 to 7, 2022.
The theme for this year’s event is: ‘Step Up For Breastfeeding: Educate and Support’.
It would be recalled that the United Nations Children Fund (UNICEF) had recommended that children be initiated to breastfeeding the first hour of birth and exclusively breastfed the first six months of life.
However, some nursing mothers, who spoke on the celebration in an interview said, poverty was hampering their effort to exclusively breastfeed their babies for the first six months of birth.
Accordingly, Esther Alaka, a nursing mother said, “you must eat well before you can give your babies breast.
