The potato is part of many household memories, but after 60:

  • It has one of the highest glycemic indexes among vegetables.
  • It causes intense spikes in glucose and insulin.
  • In the long term, it can wear down the pancreas, promote type 2 diabetes, and increase chronic inflammation.

In addition, it belongs to the nightshades and may contain:

  • Solanine and chaconine, toxic alkaloids especially present in:
    • green potatoes,
    • sprouted potatoes,
    • damaged potatoes.

How to reduce risks:

  • Totally avoid potatoes with green parts or sprouts.
  • Prefer steamed or baked potatoes, with skin on and in moderate portions.
  • Let it cool after cooking: resistant starch is formed, which behaves more like fiber.
  • Avoid French fries, very creamy purees with butter and cream.

3. Aubergine: beneficial, but not for everyone or in any way

Aubergine is another nightshade with two sides:

  • It provides fiber, flavonoids and anthocyanins, good for the heart and inflammation.
  • But it also contains alkaloids and oxalates that can:
    • aggravate discomfort in people with arthritis,
    • promote the formation of kidney stones,
    • cause discomfort if consumed raw or very unripe.

Guidelines for safer consumption:

  • Never eat it raw or in large quantities.
  • Cook it in the oven, on the grill or sautéed with olive oil.
  • Moderate your intake if you have a history of kidney stones or joint pain.

4. Jicama: refreshing, yes… but with a skin that can’t be eaten

Jicama seems like a perfect choice: fresh, crunchy, light. But:

  • The skin and inedible root contain substances such as coumarin, which can be toxic.
  • Consuming it without peeling it well or using inedible parts can cause:
    • nausea
    • Vomiting
    • severe digestive upset.

The white, well-peeled part does offer advantages:

  • Low in calories.
  • Rich in soluble and insoluble fiber, which improves digestion.
  • Low glycemic index, ideal for controlling blood sugar.
  • It provides potassium and vitamin C, useful for blood pressure and the immune system.

Security keys:

  • Always peel the jicama thoroughly.
  • Consume it in moderate amounts.
  • Buy from reliable places and prefer fresh pieces.

5. Zucchini: light and healthy, except when bitter

Zucchini is associated with light diets, but it has an important detail:

  • It contains cucurbitacins, compounds responsible for the bitter taste.
  • In high doses, these substances can be toxic and cause:
    • nausea
    • Vomiting
    • severe diarrhea,
    • abdominal pain.
