Calcium is vital for your body—healthy teeth, strong bones depend on calcium for growth. But milk is not the only source. In fact, it’s not close to being the best one.
Plant-based foods like collards, bok choy, baked beans, leafy green vegetables, soy-milk, tofu…are all high in calcium. Plus they also contain a wealth of minerals, vitamins, and micronutrients.
And that makes it dangerous for people with diabetes, pre-diabetes, family history of diabetes, as well as those suffering from insulin-related disorders like cholesterol, BP, PCOD/PCOS, etc.
