One of the most common questions for those new to the Paleo diet is “How many grams of carbs, protein and fat should I eat?”. Actually, it’s a common question for many Paleo veterans too, especially when we find ourselves falling short of health goals. Macronutrients are the nutrients we need in big (“macro”) quantities, meaning fat, protein, and carbohydrate (rather than the micronutrients like vitamins and minerals that are even more vital for health but which we need in smaller quantities). And defining an optimal dietary macronutrient ratio (what percentage of our calories should come from carbs vs. fat vs. protein) is a contentious issue.
Given the ongoing debate surrounding how much fat and carbohydrate we should be eating, hunter-gatherers offer valuable insights into what types of macronutrient ratios have supported healthy human populations. How much of their energy comes from gathered fruit and tubers? Is meat a frequent meal or a rarer delicacy? Is their fat intake high or low? Let’s have a look!

Almost 40 per cent of adults say they have taken vitamin and mineral supplements, Statistics Canada reports, but the practice may be worth rethinking, nutrition and medical experts say.
Decades ago, nutritional deficiencies were common among the general population in Canada. Since then, staple foods such as milk, flour and table salt have been fortified with vitamins and minerals to address those deficiencies.
“There's a certain amount of guilt about not eating well, and that's an easy fix,” said nutrition Prof. Mary L'Abbé at the University of Toronto. “‘Hmm, I've skipped meals, we didn't have breakfast, we didn't do lunch,' and that's often what people are doing, using it as an insurance policy. But it's only half-coverage.”
