In this Living to 100 Club podcast episode, host Dr. Joseph Casciani interviews Kimberley Gillan, author of How Low Can You Go? Nutritious Meals for $30/$50 per Week. Gillan shares her personal journey—from early experiences of food insecurity, through a cancer diagnosis, to her academic work in economics and food security—that motivated her to research and write a guide on eating nutrient‑dense meals on a tight budget. She defines nutrient density as providing maximal vitamins, minerals, and protein per unit cost, emphasizing that food is medicine. Gillan outlines low‑cost, high‑nutrient foods such as canned sardines, powdered milk, frozen peas, mixed frozen vegetables, pulses (lentils, chickpeas, beans), potatoes, dehydrated soybeans, herbs, spices, and yeast spreads like Vegemite. She explains how to use food composition tables to compare foods, and provides practical budgeting scenarios (e.g., a $10‑a‑week grocery plan) and sample meals like curries, stews, and simple soups. The conversation covers common micronutrient gaps for older adults—especially vitamin B12, zinc, calcium, and iron—and how affordable sources (tinned fish, milk powder, pulses) can fill them. Gillian also discusses the mental‑health benefits of regaining control over diet during chronic illness, the pitfalls of processed foods that cause hidden malnutrition, and the importance of flavor (herbs, spices) to stimulate appetite. She argues that fresh produce is not the only option; frozen, dehydrated, and pantry‑stable items can be equally nutritious and cheaper. The episode concludes with a warning that food prices will continue to rise globally, urging listeners to develop a “Plan B” for nutrition, and provides details on how to purchase her book and access further resources via her website.
