Blood sugar stability matters more than many people realize. Registered dietitian Jessica Cording and Dr. Uma Naidoo, a psychiatrist and nutrition specialist at Massachusetts General Hospital, break down snacks that prevent the energy crashes and mood swings that come with blood sugar spikes.

The key principle is pairing protein, healthy fats, and fiber. These three components slow down digestion and keep glucose levels steady. A snack of just crackers or fruit alone causes rapid blood sugar rises followed by crashes. Adding cheese, nuts, or nut butter changes the equation entirely.

Dr. Naidoo recommends Greek yogurt with berries and almonds as a portable option. The yogurt delivers protein, berries provide fiber and antioxidants, and almonds contribute healthy fats. The combination prevents the blood sugar spike that plain yogurt or fruit alone would trigger.

Cording highlights hummus and vegetables as an underrated choice. Hummus provides plant-based protein and healthy fats from tahini and olive oil, while raw vegetables contribute fiber without added sugars. She notes this works equally well at home or packed in a container for work.

For convenience, hard cheese and a small apple work. The dairy protein and fat in cheese balance the natural sugars in the apple. This combination addresses a common problem: eating fruit alone creates a rapid glucose spike.

Nuts and seeds deserve mention as standalone snacks. Almonds, walnuts, pumpkin seeds, and sunflower seeds contain protein, fat, and fiber in compact form. One small handful provides satiety and stable energy for hours.

The timing of snacks also matters. Eating before hunger becomes intense helps prevent overeating and poor choices driven by desperation. Cording suggests planning snacks similar to planning meals.
