AI synopsis

What people are saying

Across these discussions, participants express strong agreement with the study’s conclusions, often citing specific increases in mineral absorption (e.g., 66% for iron from sorghum), and demonstrate deep engagement by questioning population applicability and mechanisms, reflecting the research's potential to influence dietary strategies globally.

AgreementStrong agreement

Most discussions support the findings, emphasizing the benefits of adding garlic and onion to enhance mineral absorption, indicating strong consensus.

InterestHigh interest

Postings show high curiosity and engagement, with many referencing scientific studies, potential health benefits, and practical applications in diets.

EngagementHigh engagement

Several participants cite specific data points and methods, like increased absorption rates and influence on micronutrient bioavailability, demonstrating deep involvement.

ImpactHigh impact

The discussions highlight significant implications for public health, especially in populations with micronutrient deficiencies, suggesting real-world importance of the findings.

Abstract in brief

  • Garlic and onion, rich in sulfur compounds, can increase the bioaccessibility of iron and zinc from plant-based foods like cereals and pulses, both when raw and cooked.
  • The study found that adding garlic and onion to food grains resulted in significant increases in mineral bioaccessibility—up to roughly 99% for iron and around 149% for zinc in some cases.
  • These findings suggest that including garlic and onion in diets could be an effective food-based strategy to combat micronutrient deficiencies, especially in populations dependent on plant foods.

Onion and garlic naturally increase absorption of iron and zinc from foods. Many children in India have deficiency of iron and zinc which are required for growth/ concentration/skin health/immunity etc. https://t.co/DKeo2OXKxZ https://t.co/fHyJfQAHga

People who want to increase their iron and zinc absorption from food should add onion and garlic to their cooking. Sometimes you have to choose between satvik and science (tamasik) https://t.co/DKeo2PfTM7 https://t.co/fHyJfQjEea

Garlic is one of the best-tasting foods to get into your cooking, but it's also one you should prioritise as it helps improve bioavailability of iron and zinc from plant foods. Don't worry about the garlic breath, just eat more garlic

Its really a choice between science and religion finally "Higher Bioaccessibility of Iron and Zinc from Food Grains in the Presence of Garlic and Onion" https://t.co/35fNZJzLtN This is not even a study done by a "Christian evangelist' or 'Muslim terrorist' but by CFTRI, Mysore!!

Both onion and garlic have been known to increase the absorption of iron and zinc from foods, both of which are documented to be deficient in the Indian population. Normally vegetarian foods have phytates to inhibit absorption of iron. (9) https://t.co/DKeo2PfTM7

@ChrisMasterjohn Chris, here's a 2010 study showing sulfur-containing amino acids enhance bioavailability of iron and zinc in plant foods. Alliums seem to combat the malabsorption from phytates: Higher bioaccessibility of iron and zinc from food grains in the presence of garlic and onion

@kcisney @TyRBeal Careful planning. 1) Soaking and sprouting nuts and beans decreases phytates, which means greater absorption of certian minerals such as iron and zinc. https://t.co/3rqnmxa88B 2) Sulfur-rich compound such as garlic or onion combined with grains/legumes. https://t.co/8S6RSVEpKA

Não quer comer animais? Pelo menos adicione alho e cebola para minimizar o dano e melhorar o sabor. "Tanto o alho quanto a cebola mostraram ter uma influência promotora na bioacessibilidade de ferro e zinco de grãos alimentícios." https://t.co/y8csAKyyAA https://t.co/2PFD7ak0Ad

@ScepticalDoctor @The_Nutrivore @TrejbalChris Garlic and onions magnify zinc (and Iron) absorption from around 10% to 75% in pulses, 65% for grains. There had to be a reason for receipts that included both in most "sane" culinary cultures. https://t.co/Sq0xk8IV62 We don't need to breastfeed for zinc.
