What Is Nutrigenomics? The Science Of Food, Genes & Environment

“The biggest benefit of nutrigenomics—the reason that people are so drawn to it—is because it’s truly personalized medicine. People want to know ‘what’s right for my body?'” says Ginger Hutlin, M.S., RDN, owner of ChampagneNutrition and author of Anti-Inflammatory Diet Meal Prep. “I want answers to what I need for my unique situation.” 

For Lipman, nutrigenomics capability is “huge, as it can help individualize what types of nutrients (whether in food or supplements) can help different people.” Admittedly, moving away from a one-size-fits-all approach, “Nutrigenomics can help us target treatments to someone’s nutritional, genetic strengths and weaknesses,” he says.

Space mining is not science fiction, and Canada could figure prominently

In this era of climate crisis, space mining is a topic of increasing relevance. The need for a net-zero carbon economy requires a surge in the supply of non-renewable natural resources such as battery metals. This forms the background to a new space race involving nations and the private sector.


Canada is a space-faring nation, a world leader in mining and a major player in the global carbon economy. It’s therefore well-positioned to actively participate in the emerging space resources domain.

But the issues arising in this sphere are

The God Hypothesis Versus Atheist Science Denial

My friend and colleague Stephen Meyer has a superb essay at The Federalist about the major scientific discoveries in the past century that clearly point to God. Dr. Meyer points out that a large percentage of young atheists today cite science as a reason for their disbelief in God, and that is because many atheist scientists have publicly misused modern scientific findings to discredit belief in God. The public square is replete with books and articles written by atheist scientists claiming that cosmology or genetics or evolution properly understood disproves the

Humans were apex predators for two million years

Researchers at Tel Aviv University were able to reconstruct the nutrition of stone age humans. In a paper published in the Yearbook of the American Physical Anthropology Association, Dr. Miki Ben-Dor and Prof. Ran Barkai of the Jacob M. Alkov Department of Archaeology at Tel Aviv University, together with Raphael Sirtoli of Portugal, show that humans were an apex predator for about two million years. Only the extinction of larger animals (megafauna) in various parts of the world, and the decline of animal food sources toward the end of the stone age, led humans to gradually increase the vegetable element

Fantastic yeasts and where to find them: The science behind sourdough starters

This is an Inside Science story.

Sourdough bread has nurtured humans for thousands of years — perhaps even more so during the bread-making hype of the COVID-19 pandemic — and bakers have perfected the craft of making it over generations. Now, scientists are beginning to understand the identities and activities of the microbes in sourdough that are key to making a delicious loaf.

“People are making sourdough all over the world — it’s the most ancient form of bread-making and an ancient form of fermentation,” said Elizabeth Landis, a microbiologist at Tufts University near Boston, Massachusetts. But she added, “We
