The Science of Food with Dr Anneline Padayachee

As food producers, should we know more about the nutrition of the products we produce? This week on the podcast we have Dr Anneline Padayachee, a food and nutrition scientist. We dive into the fascinating world of carbs, proteins, micronutrients and more, hopefully leaving you with a better understanding of the food we produce and eat.

Anneline provides a brief history of nutrition science. This relatively new field emerged in the late 1800s, after the discovery of the elements of the periodic table, when it became possible to identify essential nutrients like amino acids, vitamins and minerals. Anneline says that nutrition science can be “ … a little bit behind … ”, as it is always reacting to changes in global diets.

Nutrition science covers the whole spectrum of diets: from the worst that lead to disease and illness, to the best that lead to populations living well past 100. Anneline discusses the concept of ‘blue zones’, regions where people live significantly longer due to an active lifestyle, a strong sense of community and a diet rich in locally sourced, plant-based foods. Anneline is quick to add that while these diets are plant-based, they are not plant-exclusive, emphasising the importance of dietary diversity and moderation in consuming animal products.

Mark asks Anneline the obvious question from a farming podcast: what is the truth about the role of meat in a healthy diet?

“If you can eat meat, go for it,” says Anneline. “Red meat is nutritionally dense. And when I say nutritionally dense, think about a concentrated cordial versus a diluted cordial. The flavour is very different, you only need a little bit of that concentrate in there. It is very nutritionally dense in protein: it has every amino acid that our body does not produce. In addition to iron, which is absolutely essential, you've also got B12. Without B12, you cannot get the energy out of your carbohydrates, so it is absolutely fundamental. And red meat is our only source of dietary B12. There's no other way we can get it, except to take a supplement or get a shot from the doctor.”

Anneline and Mark also discuss ‘lab-grown’ meat and cell culture technology in food production and how it might be used in the future. Whilst the costs to produce a kilogram of these novel foodstuffs are exponentially higher than that to produce beef at present, Anneline says there will likely be some highly useful applications of lab-grown meat, especially for the medical sector. But she finishes by pointing out: “In terms of feeding the masses, nothing is more efficient than a cow.”

This episode offers a broad exploration of food science, nutrition and health. Dr Padayachee provides valuable insight into how to maintain a balanced diet amidst the noise of marketing strategies and fad diets. Whether you're interested in the history of nutrition science, the intricacies of food production, or practical tips for a healthy diet, this episode is one not to miss.
